Napping Regularly Can Lead to High Blood Pressure and Causes Stroke, a New Study Finds

A sleep specialist said that regular naps can indicate sleep disorders.

A large new study has discovered that those who frequently nap have a higher risk of developing high blood pressure and having a stroke. 

Clinical psychologist Michael Grandner in a statement, "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." Grandner, who runs the Banner-University Medical Center's Behavioral Sleep Medicine Clinic in Tucson, Arizona, was not engaged in the study, reports CNN.

Participants in the study who slept frequently during the day were 12 percent more likely to acquire high blood pressure over time and 24 percent more likely to suffer a stroke than those who never napped. According to the study, published in Hypertension, an American Heart Association journal, when compared to people who never or seldom sleep, napping most days increased the chance of getting high blood pressure by 20% if the person was under the age of 60. 




Researchers in China examined data from UK Biobank, a biological database including genetic, lifestyle, and health information from half a million people in the United Kingdom aged 40 to 69, per a news release by AHA. 

The findings were consistent even when researchers removed persons who were at high risk for hypertension, such as those with type 2 diabetes, pre-existing high blood pressure, high cholesterol, sleep difficulties, or who worked nights. Over the course of four years, participants in the UK research supplied blood, urine, and saliva samples on a regular basis, as well as answers to questions about sleeping four times. The research, however, only gathered sleep frequency rather than length and relied on self-reports of napping, a drawback related to faulty memory.




Dr. Phyllis Zee, director of the Center for Circadian and Sleep Medicine at Northwestern University Feinberg School of Medicine in Chicago, said, "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." Zee added, "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."




According to the release, a greater number of individuals who indicated they typically napped were males with lower education and income levels than persons who claimed they never or just sometimes napped. The group which took frequent naps also smoked cigarettes, consumed alcohol on a daily basis and snored, per WebMD.  

Many of these things may have an influence on a person's sleep quality and quantity, according to Dr. Raj Dasgupta, a sleep specialist. He added, "I do believe napping is a warning sign of an underlying sleep disorder in certain individuals. Sleep disorders are linked to an increase in stress and weight regulation hormones which can lead to obesity, high blood pressure, type 2 diabetes -- all risk factors for heart disease."
