I had a set of blood tests done a couple of weeks ago, and I am deficient! In potassium and Vitamin D. I hadn't put together my recent episodes of muscle cramping with the potassium, but that's probably why I've had the pain.
I have *no* idea what's up with the Vitamin D. I don't even know why my doc requested to check the level. But I have to take some high-powered heavy-duty one-a-week pill for 8 weeks and then have the level re-checked.
By coincidence (or maybe not) Vitamin D is in the news. Apparently a lot of us aren't getting enough sun for our bodies to make adequate Vitamin D. The doc in the article recommends sitting in the shade during the middle of the day, although he doesn't say for how long (an hour? ten minutes?).
Vitamin D, when absorbed through the skin from UV rays, has been found to help prevent various cancers, multiple sclerosis, diabetes, arthritis and inflammatory bowel disease.
“People are constantly saying ‘don’t expose yourself to the sun too much’ and ‘don’t go outside between 8am and 5pm’,” Dr Turnbull said.
“My research says the best time is in the middle of the day, if you sit in the shade.”
“In the middle of the day you get more radiation from vitamin D because the sun is directly overhead and has less atmosphere to pass through.”
By sitting in the shade, harmful UVA rays that were linked to skin cancer, DNA damage and immune suppression could be filtered out, Dr Turnbull said.
“In the US, between 50,000 and 60,000 people die each year because of issues relating to not getting enough sun exposure,” he said.
I also wonder about that last line. What exactly are "issues relating to not getting enough sun exposure?" And what do you suppose dermatologists and oncologists who treat skin cancer think?
