Your sunscreen may one day list caffeine as a key ingredient. The same caffeine that gets you going in the morning also helps kill off human cells that have been damaged by ultraviolet light. It’s new research from the University of Washington. Experts say caffeine appears to stimulate cells to kill themselves off when they’ve been exposed to U.V. light. Ultraviolet rays increase the risk for several types of skin cancer Researchers say you’d have to drink at least six cups of coffee everyday t reduce your risk of skin cancer by about a third.
It may seem like busy work, but a new study says doodling can actually help a person stay focused. Plymouth University researchers evaluated 40 volunteers. They listened to a two and a half minute long phone call. Afterwards they were asked to recall names and places. People doodling during the call remembered about 29% more than non-scribblers. The lead researcher says doodling keeps a person more alert. It can also stop people from daydreaming and help them stay focused on the task of listening.
