We've all heard about the potential dangers of cell-phone use when it comes to radiation, but it turns out there could be an upside. The Wall Street Journal takes a look at a new study which explores how brain activity changes when you use a cell phone—namely, the areas of the brain nearest to the antenna show increased activity levels. While the health implications are as yet unknown, a post on the paper's health blog suggests that cell phones could someday be used as non-invasive tools to treat depression and "stimulate parts of the brain that aren't working optimally." It's an interesting theory, anyway.
And finally, a friendly reminder from your pillow: You probably need to get more sleep. A report released yesterday by the Centers for Disease Control and Prevention found that a third of Americans get less than the recommended seven hours of sleep a night. In a survey of nearly 75,000 adults, almost 5 percent admitted to falling asleep while driving—yikes. With National Sleep Awareness Week kicking off on Monday, maybe we can all resolve to get just a few more Z's.
