New study found that, People who often nap have a greater chance of developing high blood pressure and having a stroke.

In a statement clinical psychologist and director of Behavioral Sleep Medicine Clinic at the Banner-University Medical Center in Tucson, Arizona, Michael Grandner, said "This may be because, although taking a nap itself is not harmful, many people who take naps may do so because of poor sleep at night. Poor sleep at night is associated with poorer health, and naps are not enough to make up for that." He was not involved in the study.

According to the study published Monday in Hypertension, an American Heart Association (AHA) journal, if the person was younger than age 60, napping most days raised the risk of developing high blood pressure by 20% compared with people who never or rarely nap. The AHA recently added sleep duration as one of its eight essential metrics to optimal heart and brain health.

The results held true even after researchers excluded people at high risk for hypertension, such as those with type 2 diabetes, existing high blood pressure, high cholesterol, sleep disorders and who did night-shift work.
