A new study funded by the National Cancer Institute found that the combination of caffeine and exercise might help the body heal itself from sun damage.
According to the report, drinking the caffeine equivalent of one to two cups of coffee each day, along with moderate exercise, can cause the body to destroy cells with damaged DNA.
"The body has its own mechanism, called apoptosis, to help destroy precancerous cells," said Dr. Elizabeth Tanzi of the Washington Institute of Dermatologic Laser Surgery. "It turns out the combination of caffeine and exercise increases apoptosis, therefore it can protect against skin cancer."
So you might want to get a cup of joe before your morning commute. Of course, this doesn't mean you should stop using sunblock.
