Sleeping right can help your heart

Form NBC Healthcast

Getting the right amount of sleep can do your heart good. Researchers say just one extra hour of sleep each night appears to decrease the risk of calcium buildup in the arteries, which is associated with heart disease.

They found people who slept more than seven hours a night were the least likely to have calcification. That held especially true for women. Researchers aren't sure why sleep helps. But more studies are needed.
