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)
