Daylight saving time increases heart attack risk

Fresno, CA The study from the New England Journal of Medicine says daylight saving time increases your chance of a heart attack.

Researchers predict that 1 billion people around the world will get an hour less sleep this weekend.

That small amount could be enough to spike your chance of a heart attack by 5 percent.

People who are "un-fit" or smoke are more at risk.

In the same study, researchers say your chance of a heart attack goes down by 2 percent when we gain an hour in the fall.
