Do you indulge in a midnight snack? Here’s how you are risking your skin

A study found that people who eat late at night may be more vulnerable to sunburn and longer-term effects such as skin aging and skin cancer.

Sunbathers, you may want to avoid raiding the fridge in the middle of the night before catching some rays as according to a recent study, eating habits affect skin’s protection against the sun. The study in mice from the O’Donnell Brain Institute and UC Irvine showed that eating at abnormal times disrupts the biological clock of the skin, including the daytime potency of an enzyme that protects against the sun’s harmful ultraviolet radiation.

Although further research is needed, the finding indicated that people who eat late at night may be more vulnerable to sunburn and longer-term effects such as skin aging and skin cancer, said researcher Joseph S. Takahashi. The study showed that mice given food only during the day - an abnormal eating time for the otherwise nocturnal animals - sustained more skin damage when exposed to ultraviolet B (UVB) light during the day than during the night. This outcome occurred, at least in part, because an enzyme that repairs UV-damaged skin - xeroderma pigmentosum group A (XPA) - shifted its daily cycle to be less active in the day.

“It is likely that if you have a normal eating schedule, then you will be better protected from UV during the daytime,” said Takahashi. “If you have an abnormal eating schedule, that could cause a harmful shift in your skin clock, like it did in the mouse.”
