Heart attack risk shifts with daylight savings

As we get ready to turn the clocks back Saturday for Daylight Savings Time, researchers say it may also turn back the risk for heart attacks.

Researchers in Stockholm, Sweden say through studies, they've found the chances of having a heart attack goes up during the first three days after people "spring ahead" their clocks in the springtime. They say it's possibly due to sleep deprivation.

But getting an extra night of sleep, as we roll back the clocks, seems to reduce the risk for heart attack. Still the effects of the extra hour, researchers say likely only lasts one day.

During the daylight savings time shift, researchers found women are more vulnerable to heart attacks than men. And younger people overall are more at risk, likely because the retired population has a more flexible schedule and may not be affected by the loss of sleep.
