Researchers at the American Heart Association explored the link between frequent naps and cardiovascular diseases. The study is published in the journal Hypertension.
In the study, the researchers used both observational analysis and Mendelian randomization (a genetic risk validation) for over 500,000 participants living in the UK and aged 40–69 years.
The participants regularly provided blood, urine, and saliva samples, as well as information about their genetics, lifestyle, and health. They also presented reports of afternoon naps and stroke or high blood pressure.
During analysis, the participants were divided into three groups based on self-reported napping frequency: “never/rarely”, “sometimes”, or “usually”.
The results revealed the link between frequent daytime napping and an increased risk of stroke or high blood pressure. The groups with a higher percentage of frequent nappers were also associated with low education and income levels, frequent tobacco and alcohol use, and sleep disorders (like insomnia, snoring, etc.).
One of the lead researchers, Dr. E. Wang, remarked: “These results are especially interesting since millions of people might enjoy a regular or even daily nap.”
