Napping Regularly Linked To High Blood Pressure And Stroke - Study

Category: Health Matters 

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

“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,” said clinical psychologist Michael Grandner in a statement. Grandner directs the Behavioral Sleep Medicine Clinic at the Banner-University Medical Center in Tucson, Arizona, and was not involved in the study.

Study participants who typically napped during the day were 12% more likely to develop high blood pressure over time and were 24% more likely to have a stroke compared with people who never napped.

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, according to the study published Monday in Hypertension, an American Heart Association journal.

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.

“The results demonstrate that napping increases the incidence of hypertension and stroke, after adjusting or considering many variables known to be associated with risk for cardiovascular disease and stroke,” said Dr. Phyllis Zee, director of the Center for Circadian and Sleep Medicine at Northwestern University Feinberg School of Medicine in Chicago.

“From a clinical standpoint, I think it highlights the importance for health care providers to routinely ask patients about napping and excessive daytime sleepiness and evaluate for other contributing conditions to potentially modify the risk for cardiovascular disease,” said Zee, who was not involved in the study.
