How springing forward to daylight saving time could affect your health — and how to prepare

WASHINGTON — Most of America “springs forward” Sunday for daylight saving time and losing that hour of sleep can do more than leave you tired and cranky the next day. Darker mornings and more evening light together knock your body clock out of whack — which means daylight saving time can usher in sleep trouble for weeks or longer. Some people try to prepare for daylight saving time’s sleep jolt by going to bed a little earlier two or three nights ahead. How to prepare for daylight saving time Gradually shift bedtimes about 15 or 20 minutes earlier for several nights before the time change, and rise earlier the next morning, too. Go outside for early morning sunshine that first week of daylight saving time, another way to help reset your body’s internal clock.
