It’s interesting, but the only recommendation is that diabetics can benefit from getting some sun.
Hi Chuck, Lazy me… but is that why everyone says we need to go for a walk? Not only does it help burn a few calories; but it also gives us that wonderful sunlight and extra bit of oxygen that brings about some healing factors.
I can only say that when I do get up and moved out doors, I have more energy:)
I know some people even have lots of house plants to to keep the air fresh,clean and much more healthy in their homes.
I"ll go back and read more in a bit… 
just had to put a off the top of my head thought in:)
MeadowLark…hee hee! It’ll remind me I got something new to learn!
OK I just read the summary! Wow! Our bodies sure do alot of stuff without us knowing a thing about it! LOL! Me thinks I’ll get off my lazy can and move outside for a little walk and maybe on sunny days chase the kids a bit more! I think I like NO and I think I’d like to know that more NO is playing in my bloodstream:D
No I haven’t read anything about it but after I had the pancres transplant then rejected the transplant Dr told me to stay out of the sun!Maybe they have made improvements on it.
I knew that lounging by the side of the pool had to be good for something!
