Humans are solar powered.

And I have only touched the surface.

Each wavelength of sunlight has a job to do.

Infrared, red, blue, UVA, UVB... they all trigger different systems.

Sunlight is a biological signal that helps to regulate:

→ Mitochondrial energy production.
→ Gene expression & circadian rhythm.
→ Appetite, fat-burning, and blood sugar.
→ Brain function, sleep, and mental clarity.
→ Immunity, wound healing, and inflammation.
→ Hormones like serotonin, cortisol, and melatonin.

Next time sometimes tells you to avoid or block the sun, you can tell them that's not a good idea.

Sunlight is a nutrient, we are solar powered.

? = Circumstantial evidence but likely in my eyes.

There is an overlap between some wavelengths e.g. Red & Infrared and visible light has not been extensively studied.
