Fewer heart attacks when clocks set back

Turning the clock back on Sunday may be good for your heart. Looking at 20 years of records, Swedish researchers discovered the number of heart attacks dip on the Monday after clocks are set back.

The healthy affect may have something to do with people getting an extra hour of sleep.

Not surprisingly, moving clocks forward in the spring appeared to have the opposite effect. There were more heart attacks during the week after the start of daylight savings time.

Researchers say this is yet more proof that sleep affects cardiovascular health.

There's more on this study in this week's New England Journal of Medicine.
