Sunlight continues to damage people’s skin and increase the risk of cancer for hours after they leave the beach and head indoors, according to a study published in the journal Science.
Stepping under the shade of an umbrella after soaking in some sun might feel like an instant cool, but your skin cells have a postsunshine hangover that lasts for hours.
