Don't forget to turn your clock back an hour this weekend, and try some simple tips to get more restful sleep.
The switch from Daylight Saving Time to Standard Time officially occurs at 2 a.m. Sunday morning, and it moves one hour of daylight from the evening to the morning.
"For the body, the time changes are like jet lag—they sleep-deprive the patient at the time of the time changes," said Dr. Jordan Josephson, a sinus, snoring and sleep apnea specialist at Lenox Hill Hospital, in New York City. "Even an hour changes your circadian rhythm and this can give you problems for weeks."
But another expert said that people can ease into Standard Time by starting a bit early.
"The most important thing is to try to change one of the clocks on Friday and start following that clock to eat meals, sleep and wake according to that clock. When Monday comes you will be better adjusted," said Dr. Praveen Rudraraju, director of the Center for Sleep Medicine at Northern Westchester Hospital in Mt. Kisco, N.Y.
