Sunny (Vitamin) D

I recently returned to Michigan from a weekend trip to Arizona. I spent nearly two full days laying in the sun and zero days sightseeing or even shopping. Besides the obvious relaxation of lying around all weekend, I have now convinced myself that I was also being healthy (sort of).

New research has shown that vitamin D in the body has significant protective effects against the development of cancer because it regulates cell growth, cell differentiation and cell death. This is supported by evidence that sun exposure, which helps in the production of vitamin D, can have anticancer effects. Different people have different levels of vitamin D in their bodies; therefore some individuals may be able to achieve more vitamin D related protection against cancer than others. Generally those with darker skin require more time in the sun to produce the same amount of vitamin D as those with lighter skin. Of course, season, proximity to the equator, time of day, cloud cover, smog and sunscreen affect UV rays exposure and vitamin D synthesis in the skin. It is important for those with limited sun exposure to supplement vitamin D in their diet. More research is needed on this topic but it is always recommend to apply sunscreen before sun exposure! And remember to also be careful not to get too much sun exposure as the risk of skin cancer will increase as well.
