I am one of those 'Nuts' that thinks sunshine is good for you. I also think there is more to it than just vitamin D, but that is for another post.
I cannot help but notice in my twenty plus years of practice that nearly all of my Breast Cancer patients have what I would call an unhealthy pallor. There is a trend among women to avoid the sun, wear sunscreens in nearly all cosmetics and if they go to a Tanning Bed they go to the ones with only UVA which prevent the formation of any significant Vitamin D. Newer studies have suggested that Vitamin D is protective against cancer. That research is encouraging but cannot be the whole story.
Someone needs to find out.
