Spring Forward? Plan Ahead
Mar. 9 -- FRIDAY, March 6 (HealthDay News) -- You already know you'll lose an hour of precious sleep when the clocks shift forward into daylight saving time early Sunday morning.
But you may not know that you could lose a lot more if you don't take steps to ease the adjustment, experts said.
"There are more accidents on the road within two days of daylight savings," said Shelby Harris, director of behavioral sleep medicine at Montefiore Medical Center's Sleep-Wake Disorders Center in New York City. "If there are that many accidents, think about how many other things are affected."
Indeed, research released last fall in the New England Journal of Medicine revealed a jump in the number of heart attacks following both semi-annual time changes, although it was more pronounced in the spring.
According to Dr. Aparajitha Verma, medical director of the Sleep Disorders Center at The Methodist Hospital System in Houston, normal circadian rhythms (your "body clock") typically take 24 to 48 hours to readjust to time changes.
The good news is that a few simple steps can help smooth the transition. Take this advice from the experts:
- Move your bedtime up gradually by about 15 minutes every day for three days or so before the change. But don't get excited by the prospect of more sleep -- in order to fully adjust, you'll also need to wake up 15 minutes earlier. "You're basically trying to get yourself to bed a little bit earlier than you would ordinarily to get you in sync with the time change," said Dr. Nicholas Rummo, director of the Center for Sleep Medicine at Northern Westchester Hospital Center in Mount Kisco, N.Y.
- Make sure you take into account your body's other rhythms as well. Eat dinner an hour earlier and don't nap in the afternoon or evenings just before the time change, Harris advised.
- Expose yourself to bright light first thing in the morning, either by standing close to a window or even going outside for a few moments. "That tends to move the internal rhythm a little bit forward," Rummo explained. "Daytime exercise in good light has the same effect."
