From the New York Times, here.
Since my trip to Onjuku earlier this month, I have taken to getting some sun every day, now that I am not so embarrassed about my pyloric stenosis scar and slight chubbiness. OK, maybe not slight. Anyway . . ..
To answer the people who worry about skin cancer, I use the 50 SPF. I also have spent years out of the sun, in corporate cubicles and offices and the like, so I just really feel that twenty or thirty hours over a summer time isn’t going to tip things to cancer. My lower arms would be getting lethal dosages if that’s true, because they take a hit every summer. So does the skin on my face and neck area.
Now comes word that many people don’t get enough Vitamin D, which historically has been provided by the sun. That inconvenient yellow star that seems to do so much for us! This lack of Vitamin D is now suggested to contribute to a range of health deficiencies
Studies indicate that the effects of a vitamin D deficiency include an elevated risk of developing (and dying from) cancers of the colon, breast and prostate; high blood pressure and cardiovascular disease; osteoarthritis; and immune-system abnormalities that can result in infections and autoimmune disorders like multiple sclerosis, Type 1 diabetes and rheumatoid arthritis.
I don’t know how much of this is due to sedentary lifestyle (which often goes hand-in-hand with not being out in the sun), but I presume the scientists are wise enough to account for this when they do the studies.
I stopped drinking milk several years ago, when it became tougher to digest. Thank goodness for tuna and salmon here in Japan, or I might not be getting any D.
