Would you be willing to exercise a little more and drink an extra cup of coffee if you knew it could prevent skin cancer? A recent study from Rutgers University says that just might work.
In mice, the combination of caffeine and voluntary exercise heightened the destruction of precancerous cells that had been damaged by UVB rays. Caffeine alone has a protective effect, and exercise alone has a protective effect; but research shows the protection of both together is greater than their sum-a 400% increase in apoptosis (the self-destruction of cells with damaged DNA).
Researchers think that this will extrapolate to humans, and they are planning to perform a clinical trial in people.
There are over a million new cases of skin cancer in America each year, so scientists are always looking for novel new ways to deal with the increasing UVB radiation risk. However, until more studies are done to prove alternate methods of sun defense, our only dependable source of protection is sunscreen.
