Regular exercise and consumption of caffeine protect the body from the destructive effects of ultraviolet (UVA) and therefore may be associated with the prevention of skin cancer, according to a new study by Rutgers  University (New Jersey), whose results are published in the “Proceedings of the National Academy of Sciences.”

According to this research, caffeine and exercise collaborate in the destruction of precancerous cells whose DNA has been damaged by UVA, causing self-destruction. “If apoptosis takes place in cells damaged by the sun, it will slow down the progression of cancer through them,” explained one of the authors of the study, Dr. Allan Conney.

The investigation was conducted with hairless mice that were exposed to ultraviolet radiation lamps that generated that damage DNA from the cells of their skin. In turn, four groups were established, one that drank water caffeine, another who exercised running on a wheel, a third group did both, while a fourth and final group did not carry out any of these behaviors. Rodents caffeine drinkers showed about a 95% increase in apoptosis induced by UVA, which exercised showed an increase of 120%, while those who made both approached an increase of 400%.
