Sleep in a darker room

Getting a full night’s sleep is one of the best ways to control appetite and reduce your risk for weight gain, but the brightness in the room where you sleep may have an impact on your size, too. According to a study in the Proceedings of the National Academy of Sciences of the United States of America, mice who slept in environments with either bright lights or dim illumination (think: a television flickering across the room) eat more compared to mice that snoozed in total darkness. What’s more, the study found that mice that slept with lights on ate at odd times and had interrupted metabolic signals that influenced how often they were hungry. Cut out all light in your bedroom, or slip on a light-blocking sleep mask to help boost your weight-loss goals.
