Appropriate sun exposure prevents skin cancer!

Came across this interesting article today which challenges conventional thinking about the relationship between sun exposure and increases in the incidence of Melanoma. Apparently, several studies have shown that appropriate sun exposure can actually prevent skin cancer.  The rationale is that your body converts the vitamin D your body makes from sun exposure into a compound (Calcitriol) that your organs use to prepare damage from cancer cells and tumours.  It goes on to recommend exposing your uncovered skin to produce a light pink colour for optimal vitamin D production: 10 to 20 minutes for fair skinned people. The key is simply not to get burned.

Interesting stuff and seems to support my view that moderate sun exposure and appropriate protection is the way to go (though the article goes on to say that suncreams block UVB rays and hence production of vitamin D. And I’m finding it hard to accept the idea of not using sun protection even for a short period of time out in the sun) .  I’d recommend you read the full article and would be interested in your thoughts.
