The sun has a lot to do with how you look and feel. Maybe that's
why people with tans are viewed as healthier. Sunlight triggers a reaction in
your brain to make the "happy hormone" Serotonin. It boosts your
immune system to activate Vitamin D, The change in light at the end of the day
also signals your brain to make growth hormone to repair your body and
melatonin to help you sleep. (Melatonin is also a potent booster of natural
killer cells, and it has a profound impact on sex hormones, so sleep helps your
body in more ways than one).
I had a yearly habit of using a tanning booth twice a week
in the dead of winter to get light and not much of a tan. I skipped that this
year. I remembered that the last time I had this condition. it cleared with the
arrival of spring and longer days. maybe it's time to enlighten my paleface. 6
minutes in the stand up booth made a tremendous difference in my skin. My eyes
appeared to be healing a few hours later. Maybe converting the Vitamin D is the
ticket. (If you want to see a very entertaining Vitamin D lecture see Dr
