Have trouble waking up in the morning? Or maybe it’s hard to fall asleep at night? Curling up under the stars might be the answer to your woes. A new study shows that exposure to natural light cycles can help you get your body clock back on track. If you can’t escape to the great outdoors (or if you take a more “Troop Beverly Hills” approach to nature), try to increase the amount of sunlight you get during the day and put your phone and computer away at least an hour before bedtime.
