Take naps regularly? May have high blood pressure and stroke

According to a new study, people who take regular naps are also more likely to develop high blood pressure and have a stroke.

“This could be because while napping itself isn’t harmful, many people who nap may be doing so because of poor sleep at night. Poor sleep at night is associated with poor health. , and naps aren’t enough to compensate for that,” says clinical psychologist Michael Grandner.

Grandner directs the Behavioral Sleep Medicine Clinic at Banner-University Medical Center in Tucson, Arizona, but was not involved in the study.

Study participants who took daytime naps were 12% more likely to have high blood pressureand 24% more likely to have a stroke, compared to people who never took a nap.

For those under 60, napping increased the risk of developing high blood pressure by 20%, compared to people who never or rarely nap, according to the study. published this Monday in Hypertension, a journal of the American Heart Association (AHA).

The AHA recently added sleep duration as one of its eight essential measures for a healthy heart and brain.

The results held even after the team excluded people at high risk for hypertension, such as people with type 2 diabetes, high blood pressure, high cholesterol, sleep disturbances, and low-grade work. night.

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

“From a clinical perspective, I think this underscores the importance for healthcare providers to regularly ask patients about napping and excessive daytime sleepiness and to assess other conditions that contribute to a increased risk of cardiovascular disease.” CNN.

Longer naps are worse

The study used data from 360,000 participants, who provided information on napping habits to the UK Biobank, a large biomedical and research database that tracked UK residents from 2006 to 2010.

People involved in the UK study provided blood, urine and saliva samples regularly and responded four times during the four-year study to questions about naps.

However, the study only collected nap frequency, not duration, and relied on self-reports, a limitation due to imperfect collection.

“They haven’t defined what a nap should be. If you go to sleep for an hour, two hours for example, it’s not really a napexplained Raj Dasgupta, a sleep specialist and professor of clinical medicine at the Keck School of Medicine at the University of Southern California.

“A 15-20 minute nap between noon and 2 p.m. is 100% the solution if you’re sleep deprived,” Dasgupta pointed out. “If you suffer from chronic insomnia, we do not encourage napping as it takes away the urge to sleep at night.”

Most of the people in the study who took regular naps smoked cigarettes, drank daily, snored, suffered from insomnia and pretended to be nocturnal.

Several of these factors can have an impact on the quality and quantity of sleep of a person, Dasgupta warned. Poor sleep causes “excessive daytime fatigue which can lead to excessive daytime naps,” he insisted.

“I believe that napping is a warning sign of an underlying sleep disorder in some individuals,” he added.

“Sleep disturbances are linked to increased stress and weight-regulating hormones that can lead to obesity, high blood pressure, type 2 diabetes – all heart disease risk factors“, he concluded.
