It might take you a couple days to adjust to daylight saving time on Sunday, when at 2 a.m., time will "spring ahead" to 3 a.m., but you will indeed get used to that hour of light being swiped from the morning and transported to the evening. Until then, walk it off ...literally.

A poll released this week by the National Sleep Foundation found that people who exercise, even a little, enjoyed more restful sleep than people who got no exercise at all.

"I don't think we can say, on the basis of this poll, that exercise improves sleep, but people who exercise regularly are less likely to report sleep disturbance," said Dr. Barbara Phillips, the medical director of the sleep lab at the University of Kentucky's College of Medicine. She also helped put together questions for the poll, taken of 1,000 adults ages 23 to 60. Results also showed that it doesn't really matter what time of day you can get your walk into your schedule.

But walk or not the good news is most people recover from the switch to in time in a day or two. To make the transition smoother, consider these tips:-Go to sleep a little earlier Saturday. If you really want to prepare, make the bedtime earlier a little bit each night leading up to the switch.

-Get plenty of sunlight in the morning, as early as you can.

-Avoid bright lights in the evening, including the use of electronic gadgets that emit LED light.

-Even if you're tired, don't take a nap.
