A large new study has found that people who snooze more often have a higher chance of developing high blood pressure and having a stroke.

“This may be because, although napping in and of itself is not harmful, many people who nap may do so due to poor sleep at night. Lack of sleep at night is linked to poor health,” clinical psychologist Michael Grandner said in a statement. and naps aren’t enough to make up for it.Granner runs the Behavioral Sleep Medicine Clinic at Banner University Medical Center in Tucson, Arizona, and He did not participate in the study.

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

If the person is younger than At age 60, napping on most days increased the risk of high blood pressure by 20% compared to people who never or rarely nap, according to the study published Monday in Hypertension, the journal of the American Heart Association. The AHA recently added sleep duration as one of its eight primary measures of optimal heart and brain health.

The results held true even after the researchers excluded people at high risk of developing high blood pressure, such as those with type 2 diabetes, current high blood pressure, high cholesterol, sleep disturbances, and those who did night shifts.

“The results show that napping increases the incidence of high blood pressure and stroke, after adjusting for or accounting for several variables known to be associated with the risk of cardiovascular disease and stroke,” said Dr. Phyllis Zee, director of the Center for Sleep Medicine and Surgery at Northwestern. Feinberg University School of Medicine in Chicago.

said Zee, who was not involved in the study.

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

People in the UK study provided blood, urine and saliva samples on a regular basis, and answered questions about naps Four times over the course of four years of study. However, the study only collected the number of naps, not the duration, and relied on self-reports of naps, a limitation due to incomplete recall.

“They didn’t specify what the nap should be. If you are going to sleep for an hour or two, for example, it is not really a nap,” said sleep specialist Dr. Raj Dasgupta, an assistant Professor of Clinical Medicine at the Keck School of Medicine at the University of Southern California.

“A refreshing energy nap of about 15-20 minutes from noon to 2 p.m. is the 100% better method if you’re sleep-deprived,” said Dasgupta, who was not involved in the study. “If you have chronic insomnia, we don’t encourage naps because it takes away from sleep at night.”

Most of the people in the study who took regular naps smoked cigarettes, drank daily, snore, had insomnia, and reported being evening people.

Dasgupta said many of these factors can affect the quality and quantity of a person’s sleep. Lack of sleep, he said, causes “excessive fatigue during the day that can lead to excessive daytime naps”.

“I think naps are a warning sign of an underlying sleep disorder in some individuals,” he added. “Sleep disturbances are associated with increased stress and weight-regulating hormones that can lead to obesity, high blood pressure, and type 2 diabetes — all risk factors for heart disease.”
