Do you often take power naps?  It can lead to high blood pressure, study

Washington (USA): According to new research, frequent naps increase the risk of high blood pressure and stroke. The study findings were published in Hypertension, a journal of the American Heart Association. Researchers in China investigated whether frequent naps could be a potentially causal risk factor for high blood pressure and/or stroke. This is the first study to use both observational analysis of long-term participants and Mendelian randomization – a genetic risk validation to examine whether frequent naps were associated with hypertension and ischemic stroke. “These results are particularly interesting because millions of people may enjoy regular or daily naps,” says E Wang, PhD, MD,

The researchers used information from the UK Biobank, a large biomedical database and research resource that includes anonymous genetic, lifestyle and health information from half a million UK participants. The UK Biobank recruited more than 500,000 participants between the ages of 40 and 69 who lived in the United Kingdom between 2006 and 2010. They regularly provided blood, urine and saliva samples, as well as detailed information about their lifestyle. A small proportion of UK Biobank participants surveyed 4 times snooze frequency from 2006–2019. Wang’s group excluded records of people who had already had a stroke or had high blood pressure before the study began. This left about 360,000 participants to analyze the association between naps and first-time reports of stroke or high blood pressure, with an average follow-up of about 11 years. Participants were divided into groups based on self-reported nap frequency: “never/rarely,” “sometimes,” or “usually.”

The study found: *A higher percentage of ordinary-nappers were male, had lower levels of education and income and reported higher levels of cigarette smoking, daily drinking, insomnia, snoring, and more than occasional-nappers in the evening. person was reported to be; *When compared to those who reported never taking a nap, those who nap frequently were 12% more likely to develop high blood pressure and 24% more likely to have a stroke; * Participants under the age of 60 who usually nap had a 20% higher risk of developing it. High blood pressure compared to people of the same age who never napped. After age 60, napping in general was associated with a 10% higher risk of high blood pressure than those who reported never naps; * Nearly three-quarters of participants remained in the same napping category throughout the study; *Mendelian randomization results showed that the risk of hypertension increased by 40% if the frequency of naps increased by a range (from never to infrequent or usually to rarely). Higher napping frequency was related to genetic predisposition for hypertension risk.

 

“This may be because, although naps in themselves are not harmful, many people who take naps may do so due to poor sleep at night. Poor sleep at night is linked to poor health, and naps are not enough to compensate. Grandner, PhD, MTR, a sleep specialist and co-author of the American Heart Association’s new Life Essential 8 Cardiovascular Health Score, which in June 2022 as the 8th metric to measure optimal heart and brain health. added sleep duration. , “This study echoes other findings that generally show that taking more naps reflects an increased risk for problems with heart health and other issues.”

Grander is director of the Sleep Health Research Program and Behavioral Sleep Medicine Clinic and associate professor of psychiatry at the University of Arizona in Tucson. The authors recommend further investigation into the relationship between healthy sleep patterns, including daytime naps, and heart health. There are several important limitations to the study to consider. The researchers only collected nap frequency during the day, not duration, so there is no information about how nap length affects blood pressure or stroke risks. Additionally, blink frequency was self-reported without any objective measure, making the estimate non-quantitative. Study participants were mostly middle-aged and elderly of European descent, so the results may not be generalizable. eventually,
