One extremely important topic wasn't mentioned here - the impact of sunlight. For those, who feel that sunlight is crucial for their cognitive and (more important) emotional base-level, I recommend a great book by Linda Geddes - "Chasing the sun"[1].

Even 2 small studies with LED helmets that vastly improved Alzheimer's symptoms (at least for ~2 weeks, so patients need to keep up the routine; they a…

Do you notice much difference between just flashing those CCTV lights at your head vs making a helmet of some sort?

I'm curious to try it, so far I mostly see positive responses from those who have but I am yet to invest more time into researching it.

Not everyone lives in a sunny tropical paradise.

it more reminds me about sitting in front of campfire and my grandmother's house wood stove in the childhood. This is probably how i got so smart.

That would be more far infrared than near infrared, meaning there is almost no penetration deeper than 1 millimeter or stgh.
