vitamin D3. It's the Sun giving that vitamin. I've been telling people to load up on D3. Not vitamin C.
Quoting: Anonymous Coward 75133552 Lol, this is all I hear over and over again about sunlight.
Saying sunlight increases D3 is like food increases calories. There are so many incredible benefits to sunlight exposure, if it was the D3 that mattered, taking a supplement would confer you the same benefits. It doesn't.
Sunlight boosts all hormonal, immune, and neurotransmitter activity. Sunlight directly on the testicles, for instance, has been shown to boost testosterone levels DRASTICALLY, time and time again.
It speeds up your metabolism, tunes your circadian rhythm, improves sleep dramatically, which in turn increases your endogenous levels of growth hormone you endogenous release of melatonin and serotonin, increases your production of dopamine, lowers cortisol.
Some of you who have taken tropical vacations and/or spent time in the outdoors, exposing your skin for prolonged periods of time will notice you aren't getting fatter, your sleeping better, you aren't feeling stress the same way, your sex drive is boosted etc, etc
