"David, is there anything that you do to protect your skin form the sun?"
Glad you asked.
Yes. My body makes a substance called Melanin. Melanin has an interesting shape because it is composed of multiple conjugated benzene and pyrrole rings, often linked to long, complex chains and constructions.
These are able to trap (UV) photons and turn them into an electric current which my body can use. At the same time the absorption of the photons protects my DNA from damage.
Truly incredible invention.
I gradually increased the amount of melanin in my skin by gradually increasing my sun exposure over time.
But there's even more that I do:
1. I avoid seed oils wherever I can. Seed oils consist large amounts of Polyunsaturated fatty acids (PUFAs) which have a high propensity to oxidise. Since spending a lot of time in the sun can cause the formation of free radicals in the skin, present PUFAs will likely be oxidised and thus cause inflammation (i.e. sunburn)
2. I consume Astaxanthin.
Contained in larger amounts in salmon or shrimps, it can help protect the skin against damage from excess sun exposure.
3. I use a novel invention called the shade like any animal on the planet does when I notice that I've gotten enough sun for the moment.
4. I ensure that my nights are pitch black. Because regeneration of the skin and melanogenesis requires good circadian oscillations to build the foundation of future exposure.
5. (Very important) I go outside during sunrise to prepare my skin for sun exposure during the day. And I go outside during sunset again to calm my skin down with regenerative Near Infrared wavelengths.

The real crazy part is how all the guidelines and regulations are completely meaningless because damaging effects have been shown at way, waaaaay lower doses… But I guess some people aren’t ready for this conversation.

These effects are well documented and have a strong scientific background but most docs aren't even aware of them. Patients must be engaged in their own health journey these days.

A doctor recently said to my mom that a Vitamin D deficiency cannot be fixed with solar exposure.
Would've loved to asked that doctor why we then evolved to need Vitamin D for so many crucial processes in the body and developed the ability to make it from Cholesterol and sun.
Ridiculous pill shilling...

Light spectrum when I work from home. Opening a window is underrated (and free).
You can do this almost everywhere to make sure you meet your needs for Infrared light.

In Pharma class they taught us about a bunch of drugs where the mechanism of action isn't known.
I bet most could be figured out by looking at emission spectra.

According to this study (DOI: /10.1002/jbio.202300521) you can reduce your blood sugar by exposing yourself to a huge amount of 670nm light.
And you can get vast, vast amounts of 670nm light outside, from the sun. It makes sense to eat outside to dampen blood sugar spikes from meals. Eating outside should be a standard protocol for every diabetic. (This is no medical advice though)

Red LED lamps peaking at around 640nm.
Looks good, right?
But they flicker. Don't use them anymore these days. Sticking to candles.
