Heavenly Heat Saunas are the only saunas I trust enough to partner with, and I don’t say that lightly
The co-owner, Kayla Barnes, has followed me for a while, and I coincidentally learned that she owned the company on my search for a good brand
That led me down the Heavenly Heat rabbit hole via Matt Justice and was very pleased with his assessment of their saunas, from head to toe
I had my wife (a PR wizard) send them an email, which is how we got to this point
They’re the gold standard in a space that’s full of cheap materials and sloppy engineering. These guys build everything in the United States, use non-toxic wood, zero plywood, zero VOCs, and the cleanest electric heaters in the industry
You can verify the quality through Matt Justice of Certified Saunas on YouTube
No gimmicks. No nnEMF circus. Just reliable, therapeutic heat the way it’s supposed to be delivered so that you can heal and improve your metabolic health
Ultra clean build standards
No glues/adhesives for those who are chemically sensitive and need to heal from serious metabolic dysfunction
Ultra-low nnEMF & ELF with grounded faraday shielding via carbon infrared heaters that reduce electric and magnetic exposure for safety
Excellent pre-heat time
Most importantly, one hell of a deep sweat that improves your health across the board (yes, you can buy a sauna that does a crappy job of making you sweat because of the low quality build standard)
Many sauna companies cut corners. Heavenly Heat doesn’t. That’s why their units cost more, and why they last longer, hit harder, and don’t poison the air while you’re using it
I’ve partnered with them because I have always been interested in the power of sauna use for detox, infrared therapy, and more, but never had the chance to get one myself for consistent use
These are the saunas I’d put my own family in without hesitation. That’s why I’ve educated my family to have more skin in the game here
Their selection is awesome as well. The ECO infrared can fit into a closet. The 2 person combination switches between infrared and traditional. The 2 person red light therapy infrared gives you more photobiomodulation power. They even have an outdoor option
Black Friday is upon us. Now is your chance to get huge savings, especially with my own discount code thrown into the mix. Even if you decide to get one after Black Friday, my code offers substantial savings
I suggest you take advantage to save anywhere between $800-$1,100 off all models. It’s likely the cheapest price point you’ll ever get
Remember, in the sauna space, you truly do get what you pay for. Don’t be that person who makes a rash decision and buys a cheap sauna from Amazon because it has a lower price tag. They are a nightmare to have when things are going wrong
Get one for yourself and family with the link and code below. Ask questions if they arise
Enjoy Heavenly Heat Sauna quality
Use code ZAID for huge savings, in addition to the Black Friday deal

Amber light, fat cells, and nature
Researchers took human fat cells and shined different colors of light on them.. violet, blue, green, yellow, amber (nanometers), and red
Only one wavelength consistently did something dramatic:
Amber light made fat cells break down their stored fat droplets. This wasn’t done by the normal fat burning hormone pathway, but by turning on the cells cleanup and recycling machinery
Autophagy + lysosomes = internal fat digestion. Autophagy being the cell’s self-cleaning process, and lysosomes being acidic sacs that digest waste
The cell essentially ate its own fat droplets from the inside out as a result of amber light exposure
This pathway is not the classic adrenaline to HSL to fat breakdown route
The researchers even blocked the usual lipase pathways, and the amber light effect still happened
So, the study tells us that amber light activates the cell’s recycling machinery that destroys fat droplets
It’s not a stretch at all to suggest that light wavelengths can influence adipocyte (fat cell) behavior in a measurable way
•••
Every wavelength does something different in the body because different molecules and tissues absorb different photons
Blue light is highly stimulating and alerting. Red and infrared boosts mitochondrial ATP. UV-A and UV-B offer distinct benefits
Amber sits in an interesting middle zone because it penetrates deeper than blue, carries more energy than red, and interacts with metabolic tissue like fat
Amber is also heavily involved in:
• cerebellar development
• circadian signaling
• mitochondrial dynamics
• melanin intermediates
• POMC related pathways
Fat cells responding to amber light fits the pattern of amber being a metabolic wavelength
Amber exists in the natural world for your benefit. It’s most abundant during sunrise and sunset due to Rayleigh Scattering, where you have a high concentration of red/infrared/oranges/yellow/ambers
Golden hour is an amber rich experience
You literally bathe in amber light just by stepping outside during sunrise and sunset
Firelight offers a lot of amber along with many of the same wavelengths that sunrise and sunset provide
Full spectrum sunlight during the day offers amber as well, but at less concentration since it’s mixed with the rest of the spectrum
Incandescents are a man-made lighting source that is rich in amber light
By maintaining circadian alignment, you bring amber back into your life during both the day (sunrise, sunbathing, sunset, incandescents) and night (firelight & low lux incandescents)

Daylight savings time is ass on every level. Nature doesn’t observe it. The sun still rises and sets on its own schedule. We’re the only species arrogant enough to think we can “save” daylight by lying to our circadian clocks. We need permanent standard time because it aligns our social clock with the solar clock

When someone claims that a tan is a sign of skin or DNA damage, remind them that this entire narrative has its roots in eugenics and scientific racism, not objective circadian biology
The early dermatology and photobiology frameworks that demonized tanning were developed during an era when darker skin tones were pathologized, not understood
“Sun damage” became a term that conveniently upheld the pseudoscientific belief that pale skin was biologically superior, a view promoted by eugenicists who associated light skin with purity and intelligence
So, when they parrot the idea that melanin production equals damage, ask them why they’re defending a framework built on racist pseudoscience rather than updated circadian photobiology
Melanin is NOT a damage response
It’s an adaptive and photoprotective system that presents the following benefits:
1. Powerful antioxidant that neutralizes free radicals and maintains redox balance
2. Natural anti-venom that binds and neutralizes toxic compounds, including heavy metals
3. Anti-tumor agent that suppresses abnormal cell proliferation through redox and immune modulation
4. Biological nnEMF shield that dissipates excess electromagnetic stress at the cellular level
5. Detoxifying polymer that chelates and eliminates environmental toxins and heavy metals
6. Photoprotective barrier which is nature’s built-in sunscreen that adapts to UV exposure from full spectrum sunlight
7. Lipid peroxidation defender that prevents oxidative damage to cellular membranes and fats
8. Broad spectrum anti-viral that inhibits viral replication via photochemical and immune pathways
9. Anti-microbial shield that resists bacterial and fungal invasion through oxidative control
10. Neuroprotective agent that safeguards neurons from oxidative and excitotoxic stress
And so much more
God and nature infused those benefits into melanin by design. A tan is your body training under full spectrum sunlight
It’s an adaptation. That’s why it’s found throughout the entire natural world, especially in human beings, through three forms (neuromelanin, eumelanin, pheomelanin)
I’ll tie your mainstream dermatologist into a Gordian knot by forcing the question they won’t want to answer
Whose interests does this “damage” narrative actually serve?
I’ll tell you this
It doesn’t fucking serve the people

Vitamin D3 isn’t the only hormone with dozens of metabolites, endogenous melatonin also has more than a dozen identified metabolites
Counting both enzymatic and non-enzymatic pathways, researchers have cataloged at least 10-15 distinct melatonin metabolites, and the list keeps growing as metabolomics improves
Just like Vitamin D, we’re talking about a complex network with storage forms, active forms, and downstream derivatives that have a powerful impact on systemic health, especially mitochondrial function and immunity
Melatonin metabolism operates on two parallel levels:
1. Sub-cellular/local form (inside mitochondria, cells, and tissues)
2. Systemic/circulatory (pineal secretion into the bloodstream, measurable in urine or plasma)
The first is made by NIR light outside during the day, while the second is made from nighttime darkness
Melatonin is a master circadian hormone that is married to the light and dark cycle, meaning circadian alignment fosters both forms while circadian disruption destroys them
More than ever, you need to abide by bright days under full spectrum sunlight and dark nights with very minimal circadian lighting
After all, don’t you want to take advantage of endogenous melatonin’s benefits
We’re talking about anti-cancer, anti-inflammatory, anti-aging, anti-viral, anti-neurodegenerative, anti-metabolic dysfunction, anti-oxidant, and more
Melatonin is one of the most potent and versatile antioxidants in the human body, far stronger and more strategic than most dietary antioxidants like vitamin C or E
It’s in a league of its own
It neutralizes multiple types of reactive species (ROS, RNS, RCS), not just one or two like many antioxidants. It can directly quench hydroxyl radicals, peroxynitrite, singlet oxygen, nitric oxide, and more.. with no pro-oxidant rebound
Unlike vitamin C, which can flip into a pro-oxidant under certain conditions, melatonin never does
Melatonin is both water (hydrophilic) and fat (lipophilic) soluble. This grants it access to move freely through cell membranes, blood, cytosol, and mitochondria. Most antioxidants are stuck in one compartment, melatonin patrols them all
It’s one of the few antioxidants that can get into mitochondria, where most free radicals are generated. It stabilizes the inner membrane, supports electron transport, and prevents oxidative chain reactions at their source
I think the most shocking fact about it is that over 95% of your melatonin is made inside your mitochondria, not in your pineal gland, and it’s produced during the day, not just at night
Mainstream medicine still hasn’t caught up to that truth
Put some respect on endogenous melatonin

Calling sunscreen anti aging is a joke
You’re blocking the very UV and infrared light your skin uses to build collagen, make Vitamin D3, generate nitric oxide, and stimulate melanin based photo-protection
All sunscreens (both chemical and mineral based) disable natural photoadaptation and mitochondrial signaling, processes that actually preserve skin structure and youth
“When it’s black, it don’t crack” is a cultural truth pointing in the direction of eumelanin, but also melanin at large
Nature already equipped melanin rich skin with a full spectrum sunscreen and anti aging mechanism
And guess what
All skin types have melanin, you just have to maximize its longevity and function through a circadian aligned lifestyle and sunbathing framework

Circadian eyesight regeneration isn’t some fringe idea, it was the norm for our ancestors
Long before screens, sunglasses, and artificial light, human vision was constantly bathed in the sun’s full spectrum from sunrise to sunset
The daily dance between light during the day and darkness at night trained, nourished, and regenerated the visual system
Our eyes evolved in lockstep with the sun, not under fluorescents or LEDs
Mitochondria are circadian controlled organelles. Opsins are circadian controlled light sensing proteins. Melanin is a circadian and electromagnetic biological polymer
These are all light sensing mechanisms central to eye function and longevity
What we call “decline” today was once prevented naturally, and often reversed, through nothing more than consistent circadian alignment
Your ancestors didn’t need eye exercises or blue light blocking lenses to preserve their vision, their entire lifestyle was an ocular regeneration protocol because nature built it in as a feature
Every phase of daytime light carries specific frequencies that tunes and maintains the melanin, photoreceptors, retinal pigment epithelium, mitochondria, and even ocular blood flow
Contrast that with today
People spend 90%+ of their time indoors on average, staring at backlit screens under static artificial light
The retina is starved of the spectral diversity and rhythms it evolved to depend on
It’s no surprise that myopia, dry eye, and degenerative eye diseases are skyrocketing
The problem isn’t genetic, it’s epigenetic based on chronic circadian disruption because the environment has changed drastically
This isn’t pseudoscience, your own beloved mainstream research confirms the power of light for vision
Longer wavelengths like red improve color contrast vision with a single three minute exposure, with it lasting for up to one week
Violet light stops myopia through the activation of the EGR1 gene in human beings
Red and infrared regenerates opsins, while retinal dopamine made by bright light from the sun improves photoadaptation
Blue light activates melanopsin within intrinsically photosensitive retinal ganglion cells, creating systemic circadian alignment
Green light for the improvement of headaches/migraines as shown through the work of Dr. Tom Seager, with that light into the eyes peripherally being a key component of the process
UV-A stimulates the release of nitric oxide and activates the pituitary-retinal axis, affecting dopamine and other neurotransmitters crucial for eye growth and focus regulation
UV-B influences ocular immune regulation and indirectly supports tear film and corneal health through systemic pathways
This is some of the most well grounded science available to human beings, but your optometrist and ophthalmologist don’t know that

Modern medicine is broken
You can preach about how great it is for acute care, and I’ll agree, but that’s a distraction from the real issue
People like me who’ve experienced iatrogenic harm don’t care about excuses. We’ve been burned, directly or indirectly, by the very system meant to heal
As an example, the system itself, a medical bureaucracy, inflicted harm by penalizing my midwife who acted in my family’s best interest during an emergency. That’s institutional iatrogenesis
Heavy is the head that wears the crown, so take it on the chin, not up the ass
Knowing what iatrogenesis means ≠ reflecting on your role in perpetuating it. Every pilot understands gravity, that doesn’t mean crashes aren’t caused by bad training or broken systems
Complexity doesn’t excuse negligence or misaligned incentives. It’s one thing to accept risk, while it’s another to normalize harm as inevitable
Patient “self-harm” is often secondary to a system that fails to educate, empower, or create health literate citizens. The culture conditions dependency, then blames the dependent. Sounds like an abusive and alcoholic parent
“Don’t confuse your Google search with my medical degree” is the type of arrogance I’m talking about
When the entire model rewards treatment over prevention, blaming the patient for acting “autogenically” is hypocrisy
Yes, doctors may be more ethical than pharma execs or insurers, but that’s like saying the captain’s the most sober man on a sinking ship
Ethics are relative within the system, and that doesn’t absolve the profession’s complicity in the machine
I’ve seen more people heal from sunrise, movement, and truth than from any prescription written under fluorescent lights
Modern medicine doesn’t own health, but people are waking up, literally and figuratively
If I break my leg, I’m obviously going to the hospital. If I have an acute situation that requires a hospital visit, I’ll have no problem going
That’s what modern medicine should be for. Acute trauma, emergencies, saving lives when seconds matter
But don’t treat me like a fucking idiot who’s incapable of learning, thinking, or discerning truth for myself
Because where I’ll actually find health, where I’ll reverse disease, restore energy, and build resilience will never be inside those walls lit by toxic lighting
It’ll be outside
In the sun, in the cold, in the rhythms of nature that trained my biology long before medicine tried to manage it
https://blossom.primal.net/44de73cfbbac06f835bb9b00dd6811e5a318ba018382bfe8c8d89166e00662cb.jpg

2025-10-19 23:57:36 UTC

There are many Vitamin D metabolites that differ in water solubility, how long they last, and their ability to be reactivated in tissues when needed
This means your body can store Vitamin D in different forms, keep it circulating longer, and reactivate it on demand, hence Vitamin D status isn’t just about new production, but also how well your system manages and taps into these reserves
Because of this, someone with strong metabolic and circadian rhythms can stay Vitamin D sufficient longer, even with little sun, by cycling and reusing stored forms efficiently
On the flip side, if those pathways are disrupted, your body will likely struggle to access or convert those stored metabolites, leading to deficiency even if you technically have plenty in the bank
Skin type absolutely matters, but mainly upstream, at the level of how much Vitamin D you can make and store in the first place, not so much in the downstream recycling
Darker skin makes Vitamin D more slowly because higher eumelanin blocks UV-B more effectively, but once D3 is produced and metabolized, the sulfation, storage, and recycling pathways work similarly
Lighter skin can build up stores faster with less UV-B exposure, but if circadian rhythms or metabolic health are poor, they can burn through or fail to mobilize those stores just as easily
This is such a game changing and refreshing narrative involving Vitamin D3 acquisition and storage

For many, this is true

Most melanomas occur on body parts that rarely see the sun
This alone should make you pause. If full spectrum sunlight were the primary culprit, you’d expect the highest melanoma rates on chronically sun exposed areas like the face, neck, and forearms
Instead, melanomas overwhelmingly appear on the trunk, thighs, and other typically covered areas
That pattern doesn’t scream UV causation, it points to something deeper, like systemic chronic circadian and metabolic dysfunction
https://blossom.primal.net/f184f479e2a46f404357bc733586a9eb655c3eeb3bbc6e4274cb1fc3a1429721.jpg

2025-10-15 16:35:31 UTC

Here’s where mechanisms meet the real world results, and I love to see it because my most recent Substack article explains much of the why behind this
Most think it’s impossible for Vitamin D levels to rise through a cold, “sun and UV poor” Canadian winter despite no supplementation
1. Mobilization of fat stores during cold exposure. 25(OH)D is fat-soluble and stored in body fat. Frequent cold exposure increases sympathetic tone, brown adipose tissue activation, and lipolysis, which mobilizes stored lipophilic compounds, including Vitamin D metabolites, into circulation
In winter, you’re not necessarily producing new Vitamin D through skin UV-B exposure, but your body is liberating what you stored during summer, raising serum levels
2. Enhanced sulfation and circulation dynamics in cold
Cold exposure upregulates hepatic sulfotransferase activity and improves peripheral circulation
Sulfated Vitamin D metabolites like 25(OH)D₃-3-sulfate) are more water-dispersible and can act as a circulating reserve pool, re-entering active circulation when lipolysis and transport proteins shift
Likely making more Vitamin D bioavailable or detectable in standard blood tests depending on the assay
3. Seasonal hormonal and binding protein fluctuations
Vitamin D–binding protein and albumin levels are not static, they fluctuate seasonally and under stress. Cold exposure, changes in liver metabolism, and altered circadian photoperiods can shift DBP levels. A lower DBP concentration can increase the proportion of free and bioavailable 25(OH)D, which can raise measured total levels depending on the test
4. Reduced conversion to active metabolites
In colder months, metabolic rates and sun exposure patterns shift. If less 25(OH)D is being converted to 1,25(OH)₂D (the active form), the circulating pool of 25(OH)D might actually RISE because less is being drawn downstream
Think of it like reduced spending during hibernation, the checking account balance creeps up because withdrawals slow down
5. Circadian and photoperiod adaptations
Even without external UV-B, proper light entrainment through getting AM light daily keeps the hepatic-renal axis and hormonal cascades in sync, further supporting efficient recycling and conservation of Vitamin D metabolites
Circadian alignment creates more efficient Vitamin D homeostasis
•••
All this points to some fascinating overlap that most people do not consider
A winter rise in Vitamin D likely reflects a synergy of three processes:
1. Mobilization of stored lipophilic D metabolites through cold-induced lipolysis
2. Enzymatic reconversion of conjugated metabolites into measurable 25(OH)D
3. Endogenous biophoton UV-B photochemistry acting on cholesterol/sulfated precursors, sustaining low level Vitamin D production even in the absence of external UV-B
This is why I advocate for sunbathing when the time is right, so you can build that reserve of Vitamin D metabolites
In winter, especially with cold exposure and good circadian hygiene, your body liberates and conserves those stores more efficiently, oftentimes enough to increase serum Vitamin D, even without new synthesis
The human animal is built for this
https://blossom.primal.net/8518ba77ac82e0db94f9b791ae732d664f4f7a7654eac343bc298a52ba22e6df.jpg

Maybe your Vitamin D3 levels aren’t meant to stay sky high all year
Maybe, just maybe, life is built on seasonal duality, not perpetual summer
Even at the equator, there’s no such thing as true perpetual summer, it’s just a different kind of rhythm. The sun might rise and set at nearly the same time year-round, but rainfall patterns, food availability, humidity, and cloud cover create their own seasonal cues that living systems have adapted to
Equatorial populations still experience cycles, they’re just less about temperature and more about rain, light diffusion, and ecological shifts. The body still syncs to these environmental rhythms
So the idea of keeping D3 status or any biological marker “locked in” year-round is ahistorical and biologically tone deaf
Even nature’s most stable environments pulse
Modern thinking treats health like a thermostat. Pick an “optimal” number and lock it in
What they fail to understand is that biology is rhythmic. Vitamin D3 levels naturally rise with abundant UV-B in summer and decline through winter, mirroring changes in light, temperature, food availability, and circadian gene expression, so forth
Forcing levels to remain elevated year-round through supplements or artificial UV ignores this deeper rhythm and turns you into a neurotic pain in the ass
Winter is a different operating mode
Just like trees shed their leaves, your physiology shifts gears.. altering hormone cascades, immune tone, and metabolic priorities. Flattening these seasonal waves may feel optimized on paper, but it often clashes with how humans actually evolved to function
The point? Health isn’t about constant abundance, it’s about respecting the ebb and flow

UV-A and blue light in the morning from the sun boost T-cell motility and immune surveillance through nitric oxide release and specific photoreceptor pathways in the skin
This effect is spectrally coordinated along with circadian timing
UV-A rises after dawn, alongside visible light and IR, priming immune cells to patrol tissues more effectively
Tanning beds, on the other hand, blast narrow UV spectra in isolation, nearly always without the proper timing, visible light balance, or infrared context that drives this immune activation
So while they may pigment the skin or raise Vitamin D with repeated use, they don’t replicate the immune tuning role of sunlight.. no sunrise gradient, no nitric oxide surge, no circadian signaling
The devil is in the details here

Tanning bed salon culture is one of the strangest modern subcultures
It’s built entirely around light, yet next to no one involved understands anything about light or circadian biology
Instead, the entire experience gets reduced to chemical bronzers, accelerators, collagen “boosters,” and gimmicky lotions with names like “Mermaid,” “Dark 47,” and “Power Up,” all while blasting isolated UV and other wavelengths in artificial indoor environments
And to call your most advanced tanning beds “full spectrum” is a joke. It’s marketing garbage
They chase a tan, but completely ignore the timing, spectrum, and circadian signaling that make sunlight life giving
Talk about a perfect microcosm of modern confusion. Obsessing over the appearance of a tan while completely ignoring the physiological context that makes real sunlight regenerative rather than disruptive

Carrying your phone directly against your body (especially next to sensitive tissues like breasts, ovaries, or testes) means you’re placing the source of non-native electromagnetic emissions millimeters away from cells, not meters
Total abuse of the inverse square law
Electromagnetic fields obey the inverse square law: Doubling the distance drops the intensity by a factor of four. Keeping the phone on your body = maximum exposure
For most of human history, the body experienced only natural (native) electromagnetic fields from the Earth’s Schumann resonances, cosmic background radiation, and sunlight’s broad spectrum
Suddenly, we’re placing high frequency, pulsed nnEMFs directly on reproductive glands, mammary tissue, and major nerves for hours a day, often overnight
These tissues are highly vascularized (absorbing more energy), hormone sensitive (breast, testes, ovaries), and Undergo constant cellular turnover, making them more vulnerable to chronic stressors
Even if we set aside debates about long term carcinogenicity, constantly bombarding sensitive tissue with an artificial signal source is reckless
Airplane mode is common sense
Turning your phone off or switching to airplane mode when it’s on your body:
1. Eliminates active signal emissions
2. Costs you nothing (you can still use offline apps, camera, notes, etc)
3. Restores a basic buffer between your body and nnEMFs
You wouldn’t sleep with your head next to a running microwave or keep a heat lamp pressed against your skin all day
So why carry a mini transmitter in your bra or pocket for hours on end?
This isn’t fear mongering, it’s the intersection of physics and biology, otherwise known as biophysics
Your body is an electromagnetic system. Your phone is a transmitter. Distance matters. Sensitive tissues matter. And airplane mode is the simplest, lowest cost way to reduce unnecessary chronic exposure
https://blossom.primal.net/5260c5e6253275759af54463a0c93207002fa2ea018b39401357b6093c504b1f.jpg

The undeniable evidence that your mitochondria are light-sensing organelles which use the sun’s full spectrum for energy production
Here’s what will put those who speak ill of the sun to shame
Let’s start with the basics
Your body evolved to be under the sun’s full light spectrum, which is why every aspect of it is designed to sense and use light
How can I prove this?
Because we have chromophores all over the exterior and interior of our bodies
Chromophores are molecules or parts of molecules responsible for the color of compounds
They are typically the parts of a molecule that absorb visible light or ultraviolet light, leading to electronic transitions
When a chromophore absorbs light, it moves to an excited state, and the energy associated with this transition often falls within the visible spectrum, which is why we perceive color
So, how does this tie into the mitochondria?
Well, each mitochondrion in your body contains a series of complexes which are designed to transfer electrons through redox reactions to produce energy (ATP)
This chain of complexes is what we call the electron transport chain, and it’s found within the inner mitochondrial membrane
Mitochondria are the lifeblood of each cell, hence they make all the difference between health and disease, life and death
It ties in perfectly because of this fact:
The entire electron transport chain is LOADED with chromophores which are critical to the function of these complexes
Now here’s where it gets fun
I told you that your mitochondria are light-sensing organelles
Now here’s why
⚡️ Complex I (NADH:Ubiquinone Oxidoreductase)
• Flavin Mononucleotide (FMN): Absorbs light at around 370 nm (UV) and 450 nm (blue light)
• Iron-Sulfur Clusters: These clusters have broad absorption, typically in the 400-600 nm range, but they don’t have distinct peaks like other chromophores
⚡️ Complex II (Succinate:Ubiquinone Oxidoreductase)
• Flavin Adenine Dinucleotide (FAD): Absorbs at around 370 nm (UV) and 450 nm (blue light)
• Iron-Sulfur Clusters: Similar to Complex I, absorption is broad and typically in the 400-600 nm range
⚡️ Complex III (Cytochrome bc1 Complex)
• Cytochrome b:
- bL (low potential form): Absorbs at around 563 nm (yellow-green)
- bH (high potential form): Absorbs at around 566 nm (yellow-green)
• Cytochrome c1: Absorbs at around 552 nm
• Rieske Iron-Sulfur Protein (2Fe-2S cluster): Absorption is broad, typically between 400-500 nm
⚡️ Complex IV (Cytochrome c Oxidase)
• Cytochrome a: Absorbs at ~ 605 nm
• Cytochrome a3: Absorbs at ~ 655 nm
Both orange and red light absorbed here
• Copper Centers (CuA and CuB): These centers absorb broadly in the visible region, but their exact absorption properties are less defined than the heme chromophores
⚡️ Additional Chromophores in the ETC
Ubiquinone (Coenzyme Q): Ubiquinone itself is not strongly absorbing in the visible spectrum but does have weak absorption peaks in the UV range, around 275-290 nm
Biophoton emission right there
⚡️ Cytochrome c (Mobile Carrier)
Cytochrome c has an absorption wavelength of ~ 550 nm (in reduced form)
Now here’s the million dollar question
Why does the entire electron transport chain sense various wavelengths of light from the sun at extreme precision?
I want to see the look on every physician, dermatologist, and ophthalmologist’s face when they’re shown this information
The overall absorption range of the chromophores within the electron transport chain is between ~ 200 nm to ~ 900 nm
From extremely low-frequency UV light (biophotons) to NIR light
Any argument against sunlight exposure or the use of sunglasses, sunscreen, sun-avoidance is hereby deemed as retarded knowing this information
This is especially the case because mitochondria control the health of every cell and are found everywhere in the body
I rest my case
https://blossom.primal.net/568378c21b48ac45b6825837afc097d33e9b30cf77da954e33cd107cbe026c56.jpg

Mitochondria gives cells a tan
You read that correctly
Let’s put this reductionist notion that mitochondria are simply the powerhouse of the cell to rest
They surpass that simplistic label, as they play a far more complex role, including a significant influence on skin pigmentation and melanin development
•••
Mitochondria are involved in various cellular processes that affect skin pigmentation:
They are the energy supply for melanin production through their ability to provide ATP, essential for the biosynthesis of melanin
Mitochondria produce reactive oxygen species (ROS), which can influence melanin production. An increase in ROS can stimulate melanogenesis, leading to darker pigmentation
They control apoptosis (programmed cell death), affecting the turnover of melanocytes, which are the cells that make melanin (PMID: 19659442)
Mitochondria regulate calcium within the cell. Proper calcium uptake by mitochondria is essential for melanin production in melanosomes (PMID: 39527653)
Mitochondria sit at the heart of redox balance. They regulate the redox environment, which in turn influences the stability of tyrosinase, a key enzyme in melanin synthesis, and affects melanosomes
•••
What more proof do you need that melanin production is a cornerstone of human health?
Stop listening to centralized dermatologists who view biology and skin through a reductionist lens
It’s time to cultivate your tan through wise full spectrum sun exposure, aligned with a circadian appropriate framework

Because it’s not just about color temperature, which is a superficial metric. It involves light spectrum, flicker rate, so forth. LED’s in the conventional sense offer isolated blue light, which is very damaging to a circadian system that evolved for full spectrum sunlight during the day and darkness at night.

The most sophisticated healing technology in existence is a sunrise
Think of it as a reset button for your body
It’s a technology older and more precise than anything humans have ever engineered
At first light, red and infrared wavelengths flood the environment, charging mitochondria and priming cellular repair
As the sun rises higher, UV-A arrives, stimulating nitric oxide release, circadian hormone signaling, and the POMC pathway that ties together mood, energy, skin protection, and immune function
Then UV-B delivers its irreplaceable gift, Vitamin D3 production, the master regulator of immunity and cellular health
Understand that this sequence isn’t random. It’s an orchestrated rollout of light frequencies, a code written into biological systems over billions of years
Every ancestor before you relied on this signal to synchronize metabolism, brain chemistry, and sleep
Compare that to modern technologies.. pills, lab manufactured supplements, artificial lights.. all of them clumsy, fragmented attempts to imitate what the sunrise does effortlessly each morning
When you watch a sunrise, you aren’t just seeing light, you’re witnessing the most advanced regenerative technology ever deployed on Earth
It costs nothing
It carries no side effects
It works flawlessly
Forget the fads, tap into what’s timeless

Circadian alignment is the single most powerful foundation for preventing cancer across your lifespan, especially skin cancers
“But doesn’t UV from the sun raise your risk of developing all forms of skin cancers?”
No, the centralized narrative has more epistemological holes than Swiss Cheese
I have exposed many of these contradictions in my work here, on Instagram, and on my Substack
People simply do not know that all anti-cancer defenses in the body are under circadian control, from autophagy to tumor suppression
What do you think happens to the body of the average person who spends 90+% of their time indoors with a Vitamin D3, endogenous melatonin, infrared, UV, and full spectrum deficiency?
They experience a chronic breakdown of all these anti-cancer defenses, which opens them up to a dramatically increased cancer risk in all forms
Don’t act like modern medicine has everything figured out. I’m teaching physicians about this work. The system has utterly failed to educate from circadian first principles for many reasons
By keeping yourself in sync with the light and dark cycle, you create the biological conditions that allow your cells to repair, regenerate, and defend against mutations before they spiral into malignancy
The circadian system orchestrates DNA repair enzymes, immune surveillance, melatonin secretion, and mitochondrial function.. processes that together act as the frontline defense against uncontrolled cell growth
When you consistently rise with the sun, expose your skin and eyes to full spectrum sunlight, move in alignment with daylight hours, and protect darkness at night, you’re not just “living healthy”
You’re hardwiring your body’s innate cancer prevention system, day in and day out
This is especially crucial for the skin, an organ directly wired to the solar cycle
Proper light exposure builds melanin, strengthens antioxidant pathways, and trains your skin to benefit from solar eustress
Cancer prevention isn’t just about avoiding toxins or eating clean food, it’s about honoring the master and peripheral circadian clocks
Circadian alignment places you in the biological state where disease struggles to take root
You hold such strong energy for “fuck cancer” campaigns for reasons that I understand, maybe it’s time to do some shit about it
It’s not enough to talk about how much you hate cancer, give yourself the practical circadian tools to prevent it in the first place

“Sun ages the skin”
Here’s what you’re really saying:
“I’ve been programmed to fear the sun without context. I don’t know that UV-A, UV-B, infrared, and visible light interact like a symphony, not a single note. I don’t know that progressive exposure builds a tan, strengthening skin the way lifting builds muscle. I don’t know that circadian biology is the master regulator of every anti-aging process, from autophagy to collagen repair. So instead of first principles, I repeat fear slogans as if they were wisdom”
Don’t be a parrot who repeats pre-packaged slogans without understanding the biology underneath
Too many recycle a dermatology marketing script, word for word, without ever digging into the mechanisms, context, or nuance

Take those sunglasses off. Full spectrum sunlight into the eyes peripherally controls every major hormone and neurotransmitter in your body. There is a direct endocrine connection. The eyes are simply an extension of the brain and skin. One neuroectoderm circadian unit with no separation and full on bidirectional connection. Let God’s light grace your bare eyes

When your circadian rhythm is chronically disrupted, your body builds up wear and tear over time
This is what we call allostatic load
The retina specifically plays a key role in setting your master and peripheral circadian clocks through light, so if it gets damaged through isolated blue light exposure (as in most people’s experience), it adds extra stress to the entire system
Ongoing circadian disruption slowly wears your body down, and retinal damage makes that stress worse because it disrupts how your brain senses and responds to light
Retinal damage does NOT stay local
It weakens your body’s ability to keep time, amplifying the overall physiological stress from circadian disruption
https://blossom.primal.net/d0cd5fe25d5993863d81e34a37ca0fb7b67bc656a60395cec1811d860d77657b.jpg

Collagen, elastin, and every other part of the body that signifies youth are meant to be used, not preserved like fragile relics
The weakest thing you can do is orient your entire life around clinging to these components of youth, because in doing so, you’re automatically playing defense against a loss that is both certain and unavoidable
Youth is temporary by design
Its purpose is to be expressed, exhausted, and transformed into wisdom, resilience, and depth
To obsess over holding onto it is to miss the greater game of life, growth
But in all of this, there’s a paradox
When you live in circadian alignment, you actually get the best of both worlds
Morning and daytime exposure to red and infrared light stimulate the body’s own production of collagen, elastin, and hyaluronic acid, keeping your skin youthful, your tissues resilient, and your life vibrant, all without obsessively chasing the anti-aging gimmicks
You live fully, and in return, nature keeps you both youthful and healthy

A bolt of lightning is nothing more than massive charge separation and rapid discharge across a potential difference
Mitochondria do the same thing, but on a cellular scale. They strip electrons from food, pump protons to create a charge gradient (~150 - 180 mV), then discharge that gradient through ATP synthase, a molecular turbine
That proton-motive force is literally a nanoscopic electrical storm
Here’s what’s crazy
The mitochondrial inner membrane potential is around –150 mV
Given the membrane is only ~5 nm thick, the electric field across it is on the order of 30 million volts per meter (30 MV/m)
That’s stronger than the electric field in a lightning bolt
Your mitochondria are biological lightning engines that run billions of tiny lightning strikes per second, inside you, to keep you alive
Put some respect on God’s work
https://blossom.primal.net/455a978ff62281af9372fde41f1425c33de9c0ce4d820f9a270ef0aff843c0d3.jpg

On nano and “non-nano” sunscreens
1. Your skin circadian driven organ
Barrier function (stratum corneum tightness, lipid organization, permeability) varies by time of day, usually strongest at night and weakest during the day
Sunscreens are mostly applied in the morning/daytime, precisely when skin is naturally more permeable and meant to interact with full spectrum sunlight
Nanoparticles slipping in during this window is problematic
2. Metal ions in the blood act as circadian clock disruptors
Zn²⁺ is not neutral. It’s a powerful cofactor in transcription factors, enzymes, and synaptic signaling
Sudden spikes from non-dietary routes (skin → blood → CSF) could scramble local zinc homeostasis that’s usually tuned to food intake timing and gut absorption
Titanium (TiO₂ NPs) is even trickier because bulk TiO₂ is inert, but nanosized TiO₂ generates EXCESS reactive oxygen species under UV, throwing off the intricate balance involved with ROS and RNS within the system
3. Consider the circadian consequences
🌞 Melatonin suppression at the wrong place/time
Zinc and titanium nanoparticles can accumulate in mitochondria, altering ROS signaling
Melatonin is not just made in the pineal gland. It’s also made locally in mitochondria via the sub-cellular form
if nanoparticles hijack redox homeostasis, melatonin’s nighttime signal weakens
🌞 Central vs peripheral clock confusion
The skin clock reads the light in your environment, while the liver clock reads the food environment. Introducing artificial nanoparticle stressors through the skin is like giving the skin clock false input, which then feeds back to the SCN
🌞 Neurotoxicity risk
If Zn²⁺ ions cross into cerebral spinal fluid, they can modulate NMDA receptors, excitability, and even contribute to neurodegeneration
This is especially concerning when exposure happens daily in sync with sunlight, the very zeitgeber meant to entrain brain clocks
•••
Normally, sunlight enters through your skin and sends clean signals to your cells and brain about what time of day it is
When you cover your skin with nanoparticles, you’re letting tiny foreign particles slip inside
Instead of sunlight guiding your body’s clocks, these particles interfere with the signal, creating confusion in how your cells and brain read light
This blunts the natural circadian benefits of sunlight (progressive UV tolerance, melanin signaling, nitric oxide release) while layering in an unnatural, time dependent toxic load
From a circadian standpoint, ZnO and TiO₂ nanoparticles in sunscreens aren’t just a toxicology problem
They’re an information problem
They introduce chaos into a system that relies on precise temporal signaling from light, food, and redox balance
Put simply, they trick your body into thinking they’re part of sunlight’s signal, but instead they scramble your internal clocks
•••
Both nano and so called “non-nano” sunscreen options have issues, just different flavors of them
Nano (ZnO, TiO₂)
Nanoparticles can slip through the skin into blood and even CSF, disrupting metal balance, oxidative stress, and circadian signaling
Nano TiO₂ also acts like a photocatalyst, generating excess free radicals under UV light that damage cells
When washed off, these particles pollute rivers and oceans, harming plankton, corals, and fish
Yet companies still label them “safe mineral sunscreens,” where “safe” often only means not immediately irritating, not truly circadian or mitochondrial safe
Non-Nano (larger ZnO, TiO₂ particles)
“Non-nano” particles are often just slightly bigger than the nano cutoff, but can still fragment into smaller pieces on the skin
They block UV-B, the very wavelength range needed for Vitamin D3 production, while leaving a white cast that companies often “fix” by secretly blending in smaller particles
Even larger ZnO can still leach zinc ions into sweat and the bloodstream, just at lower levels than true nanoparticles
Nano = higher penetration risk + excess ROS stress
Non-nano = less penetration, but still blocks critical light wavelengths and often hides nano fragments anyway
Both confuse the circadian system by replacing evolutionary light signaling with an artificial barrier or intrusion
This is why I’m so strict on my recommendation of no sunscreen use, in any form
What I just laid out here is informed consent in practice, not the typical nonsense of “use this XYZ sunscreen to avoid burns”
I choose no sunscreen because the body only adapts in the way it should by respecting circadian principles and implementing progressive overload for melanin development
Sunlight exposure when UV-A and UV-B are out isn’t to be abused
It must be approached with gradual, mindful exposure rather than reckless overexposure
And if you choose to be in scenarios that increase the risk of overexposure, while using any sunscreen option, that’s your choice
Again, informed consent

The story I hope people will tell when I’m gone is that I reminded them the sun was enough
That I helped them see their body as perfectly designed, not broken
That I have them the tools to reclaim their health without fear, dogma, or dependence on a system that profits from disease management and sickness
If people say, ‘Because of Zaid, I started watching sunrise, developed a mad tan, changed how I lived, and passed that wisdom to my kids,’ then I’ve done my job
That’s the legacy I want
A ripple effect of people realigning with nature’s rhythm. Circadian alignment en masse

Blue light has the ability to shrink adipocytes (fat cells) and make them more efficient at burning fat
But wasn’t this study done using isolated blue light, divorced from full spectrum sunlight?
You’d be correct
I will always argue that the results would be way more impressive with full spectrum sunlight because it shows us the full effect, rather than just proof of mechanism
This study narrowed in on 450 - 480 nanometer blue light to show melanopsin/TRPC signaling in fat cells
That’s elegant for mechanistic proof, but it only scratches the surface
In nature, light is never monochromatic. Full spectrum sunlight is polychromatic and carries a dynamic orchestra of wavelengths (UV-A, UV-B, violet, green, red, infrared), all working in layered synergy
What we see in this paper is the bare minimum effect. Blue alone tweaks lipolysis and adipokine signaling
But in the real world, those signals would be amplified, modulated, and stabilized by the rest of the spectrum
Researchers often isolate a single wavelength to prove mechanism, in this case, that subcutaneous white adipocytes (scWAT) have a melanopsin/TRPC mediated light sensitive pathway
By showing that just blue light can trigger measurable currents and metabolic changes (lipolysis, adiponectin/leptin secretion shifts, reduced lipid droplet size), they establish causality
Melanopsin (the blue light sensing opsin found throughout the body) absorbs in this range and directly mediates fat cell signaling
This study shows proof of principle
Your fat cells are literally photoreceptive, they “see” blue light through melanopsin and change metabolic behavior in response
What does this mean from a physiological standpoint?
That under the sun, blue light within the full spectrum helps tune fat metabolism, aligning lipolysis and adipokine signaling with the day’s activity/eating cycle
But, this is a two way street
It also means that isolated blue light at night will distort adipocyte signaling, promoting fat storage, leptin/adiponectin imbalance, and metabolic dysfunction through circadian disruption
If the researchers used full spectrum sunlight (or at least a solar simulator), they likely would have seen:
🌞 Greater lipid mobilization because of red/infrared synergy
🌞 Stronger leptin/adiponectin modulation (hormonal entrainment, not just a stress response)
🌞 Circadian phase reinforcement with UV + blue acting as zeitgebers
🌞 Less oxidative “noise” or stress compared to blue in isolation
Instead of proving that fat cells can sense blue, the paper would have demonstrated that sunlight orchestrates fat metabolism through opsins in fat itself
That’s a paradigm shifting story

At least 10-15 minutes of both sunrise and UV-A rise are my rule of thumbs. I see a lot of people wearing sunglasses during the AM. It’s a major problem

Pair it with UV-A rise, which typically happens around an hour after sunrise
You’ll never complain about energy again

I would avoid looking directly at the sun unless you’re sun-gazing during sunrise and sunset. Even then, I think it needs to be done progressively because there’s an adjustment period

2025-10-11 15:37:05 UTC

I have zero respect for any culture that dares to demonize the very force that gave it life
In the 21st century, this insanity is everywhere
We smear children in chemicals that block the very wavelengths meant to build their bones and regulate their hormones.. then act shocked when autoimmune disease, depression, and obesity skyrocket
We tell people to fear midday light while trapping them under fluorescent bulbs and LED screens that fry their circadian system
We invented sunglasses so people could look “stylish,” all while severing the retinal signals that set their body’s circadian clocks
And perhaps most deranged of all, we convinced billions that the star that sustained life for four billion years suddenly became a carcinogen sometime in the last century
That’s not science, that’s cultural brain rot dressed up as hot shit
To curse the sun, to fear it, to brand it as dangerous is to spit in the face of your own body, and in the face of God
Civilizations once built temples to the sun, knowing their survival depended on reverence, not rejection
Yet here we are, in an age that calls itself “advanced,” teaching kids to hide from daylight while chronic disease eats society alive
People act like lathering sunscreen, popping vitamin D pills, and hiding indoors is cutting edge wisdom
No, it’s the most pathetic imitation of health we’ve ever seen
Demonizing the sun is cultural suicide, and the decay is already here, rotting people on the individual and collective level in real time
This is the schizophrenia of our age
People worship artificial light, while fearing the most perfect source of light in the Universe
And the worst part?
We parade this madness as if it’s the hot new gospel, when in reality, it’s the blueprint for mass extinction
And that’s not hyperbole
•••
No culture in history has ever demonized the sun to the degree modern industrialized society has
Egyptians, Mesopotamians, Mayans, Aztecs, Hindus, Greeks, Romans, Japanese, the list goes on. Almost every civilization you can name elevated the sun to god like status. Ra, Helios, Surya, Inti, Amaterasu.. these were central deities, not enemies
Even when solar intensity was feared (like droughts or scorching heat), it was never demonized in the sense of being cast as inherently toxic
It was treated as a force to respect, appease, or balance with ritual rather than something to chemically block or hide from
Sunlight was woven into healing practices as well. Heliotherapy for tuberculosis, rickets, and skin conditions is documented in both ancient Greece and up through the late 19th century in Europe
Only 20th and 21st century Western medicine, backed by centralized dermatology, Rockefeller Medicine, and chemical industry interests, flipped the sun into an existential threat
Sunscreen, sunglasses, sun avoidance campaigns, dermatology “truck driver” scare stories, this is a modern Frankenstein creation
We are literally the first and only culture in history to tell our children that the light which sustains all life on Earth is dangerous
What’s crazy is that this isn’t just some low grade fear, it’s institutionalized paranoia based on the most ghoulish “science” to date
Albino mice under isolated UV
Skin cell cultures under isolated blue
Epidemiology that can sometimes hint at big patterns, but are by no means final answers
Are you genuinely having a fucking laugh, this is the “Science” I’m told to place all of my trust into?
This is the gospel that’s supposed to justify covering children in petrochemical sludge, banning them from daylight, and selling them a lifetime of pills, screens, and fluorescent boxes?

Light skin evolved as an adaptation to higher latitudes, where UV light is weaker
This trait allowed people to absorb ultraviolet light more efficiently, ensuring enough Vitamin D3 synthesis despite reduced solar intensity
That evolutionary gift is a blessing, an ingenious survival mechanism
But in today’s context, it can also become a curse if you ignore the principles of circadian biology
Light skin makes you more vulnerable to sudden, unconditioned doses of strong sunlight
Without respecting progressive overload (gradually building tolerance to UV exposure the same way you would increase weight in the gym), you pay the price in the form of burns and other undesirable manifestations

Thanks brother! Absolute legend ⚡️

If you buy into the centralized claim that melanin is nothing more than a marker of DNA or skin damage, then you’re basically admitting that evolutionary biology and adaptation are worthless ideas with no real backing
This is, of course, absurd
I don’t care if you’re a hardcore scientist or devout follower of religion, denying the existence of evolutionary biology is head in the sand behavior
Think about it
Why would nature preserve melanin across species, climates, and lineages for millions of years if its sole purpose was to signal cellular damage?
That would make evolution an incompetent, suicidal process
Melanin exists because it’s functional, protective, and adaptive. It’s a molecular shield, an energy sink, and a communication system all in one
To reduce it to “damage” is to ignore its role in photoprotection, redox regulation, circadian signaling, and even quantum energy transfer
The centralized narrative strips melanin of its sophistication, turning a masterpiece of evolutionary engineering into a pathology
If you call melanin a sign of damage, you’re not just wrong about skin biology
You’re essentially declaring that adaptation itself is a myth

If you’re not dedicating time to proper sunbathing with a large portion of your skin exposed, you’re not giving yourself the chance to produce meaningful amounts of vitamin D3 from UV-B exposure
For some reason, many people assume that simply going to a baseball game without sunglasses or a hat, while keeping most of their skin covered with clothes, will somehow generate sufficient vitamin D3
Absolutely not
You need actual skin in the game at the correct times and in circadian alignment
Sunlight must strike bare skin directly, and ideally in a consistent, intentional way. It’s not something you stumble into by accident. It requires a dedicated practice
Watching sunrise?
Great, you’re still not making D3
Making it dark at night?
Great, still not making D3
UV-A rise?
Fantastic, still not making D3
You must be sunbathing with BARE SKIN when UV-B is present to begin the conversion process in your body
Let me remind you of the conversion process involved here:
1. UV-B hits the skin and penetrates into the epidermis (outer most layer of the skin)
2. UV-B changes the shape of the starting molecule known as 7-DHC (7-dehydrocholesterol)
3. This UV-B induced change turns 7-DHC into Pre-Vitamin D3. With heat, pre-vitamin D3 naturally rearranges into Vitamin D3 (cholecalciferol)
4. That’s where binding for transport occurs. Vitamin D3 cannot float freely in the blood, so it binds to a carrier called DBP (Vitamin D Binding Protein), forming DBP-VD3
5. Once bound, it moves through the bloodstream where it can later be activated in the liver and kidneys into the full active hormone form (calcitriol)
I have bad news if you use any form of SPF as well, so prepare yourself
SPF 15 blocks ~93% of UV-B
SPF 30 blocks ~97% of UV-B
SPF 50 blocks ~98 of UV-B
SPF 100 blocks ~99% of UV-B
So if you use any form of sunscreen, whether chemical or mineral based, you’re blocking the very light wavelength range needed to produce D3 (also one of your most potent anti-cancer hormones)
Negligible conversion is happening, even if you do a shitty job of applying your sunscreen considering the chronic circadian disruption that a modern lifestyle creates, further worsening D3 status
People who don’t have a strong circadian education are likely to make these simple mistakes
And I see it time and time again
https://blossom.primal.net/471b36598cf33d7908eedec3f0752c3c0f2d12ec86262bd60eb980946c01ed24.jpg

All hormones and neurotransmitters in the body are directly controlled through full spectrum sunlight into the eyes peripheral during the day
Sunglasses in 99% of scenarios are a net negative because they go directly against the first principles of evolutionary circadian biology
There is no argument to be made for the use of sunglasses outside of active glare
The optometrists and ophthalmologists who try to push this narrative around UV ocular damage are out of their depth. They don’t know anything about circadian mechanisms, nor how light relates to a systems view of biology
https://blossom.primal.net/9db939860c889e3b21747f46157350dada4dd616d685396ecdaf99a609eb7ccc.jpg

2025-10-11 15:11:53 UTC

If you believe full spectrum sunlight inherently causes skin cancer or damage, your mind has been hijacked by propaganda. The good news is that truth is redeemable through circadian education

2025-10-11 15:11:20 UTC

Sunglasses, sunscreen, contact lenses, tanning beds, and prescription glasses are all man made inventions that, intentionally or not, disrupt the body’s circadian hormetic system
What once evolved to calibrate itself precisely through full spectrum sunlight is now constantly interfered with by synthetic barriers and distortions
The immediate impact of these inventions is obvious
Altered light input to the eyes and skin, disrupted circadian signaling to the brain, and changes in how the human body interact with UV, infrared, plus the rest of the spectrum
But it’s the second and third order consequences that are truly devastating, and largely invisible to the average person
When you distort the timing, spectrum, or intensity of light reaching the body, you alter hormonal rhythms, neurotransmitter balance, mitochondrial redox states, and even genetic expression through light responsive pathways
Over years, this leads to downstream issues in metabolism, fertility, mood regulation, sleep quality, and immune function
What seems like a simple convenience, a pair of sunglasses or daily sunscreen, compounds over time into chronic, systemic circadian disruption

2025-10-11 15:10:31 UTC

You’re playing with fire when you expose yourself to isolated UV light without the natural balancing forces of red and infrared wavelengths that are always present in full spectrum sunlight.
Stripping UV away from its biological context disrupts the protective and regenerative mechanisms that evolved to handle it.
