Turning Clocks Back Could Help Your Heart

The time change this weekend could be good for your heart. Daylight saving time ends at 2 a.m. Sunday. In Thursday's New England Journal of Medicine, Swedish researchers report they found fewer heart attacks the Monday after clocks were turned back an hour. They examined 20 years of records. The researchers said that moving the clocks ahead appeared to have the opposite effect.

RENEE MONTAGNE, host:

Good morning, I'm Renee Montagne. It'll feel really good to sleep in a bit this Sunday. And it will do you good, too. In today's New England Journal of Medicine, Swedish researchers write that after looking at 20 years of records, they found fewer heart attacks the Monday after clocks went back an hour. Possibly, they write, because of that extra hour of sleep. They also found heart attacks went up in the spring in the days after losing that hour. It's Morning Edition.
