RICHMOND, Va -- If your boss catches you sleeping at work, you can justify yourself by citing a new study.
According to a study presented in a London medical conference, napping may reduce a person's risk for heart attack and stroke. Researchers studied just under 400 patients who were about 61 years old and had high blood pressure.
Scientists found the patients who took a nap in the middle of the day had less damage from high blood pressure in their hearts and arteries than those who did not take naps.
The benefits were seen the most in people who napped for at least an hour.
