According to a new study, exercise and a regular coffee habit might be enough to ward off skin cancer. Researchers from the Laboratory for Cancer Research at the School of Pharmacy at Rutgers University, New Jersey, found that caffeine and exercise inhibited ultraviolet light-induced skin cancer among mice. While each of the solutions works on their own, the combination of the two works better, according to researchers, as both caffeine and exercise appear to kill UVB-damaged cells before malignancy occurs. The results were fairly dramatic. The caffeine drinkers revealed a 96 percent increase in damaged cell death, while the exercisers showed a 120 percent increase. However, the mice that drank caffeine and ran on a training wheel had a nearly 400 percent increase in the cell death of damaged cells, in comparison.
All the same, according to the Skin Cancer Foundation, people shouldn’t jump to conclusions about the efficacy of these results in humans. Caffeine, when applied topically, has been popular as a cosmeceutical anti-aging ingredient, but the concept of systemic caffeine needs to be researched more deeply.
