Sun Helps Prevent NHL?!

In the International Journal of Cancer, December 10th issue, Australian researchers report sun exposure apparently has a protective effect against the development non-Hodgkin's lymphoma (NHL).

Dr. Anne Kricker, of the University of Sydney, and colleagues investigated the possibility that high sun exposure is associated with an increased risk of NHL -- and found the opposite!

The risk of NHL decreased with increasing hours of sun exposure. With the highest exposures, the odds of having NHL decreased by 35 percent compared with the lowest exposure level.

One effect of sunlight is to stimulate the body's production of vitamin D. The researchers say that "increasing evidence that vitamin D may protect against cancer makes ultraviolet-mediated synthesis of vitamin D a plausible mechanism whereby sun exposure might protect against NHL."

Now you might be at risk for skin cancer so don't overdo it!
