Scientists have told the danger of frequent daytime sleep


    Scientists told what is dangerous frequent naps

    Many people like to take a nap or two, but as the researchers note, if you regularly “pass out” in the middle of the day, you should pay special attention.

    According to In a new expert study, frequent or even normal daytime naps may be associated with an increased risk of hypertension and stroke, writes USA Today News.

    Study results showed that frequent naps in adults were associated with a 12% increase in risk of developing high blood pressure and a 24% higher risk of stroke compared to those who do not take a nap during the day.

    For the experiment, the experts used information from the UK Biobank, a biomedical database that contains anonymous genetic and health information from half a million UK participants. It is also worth noting that all recipients did not have hypertension or stroke at baseline.

    The nap frequency survey was conducted 4 times between 2006 and 2019, with at least 5,000 participants each time. Participants self-reported whether they nap “never/rarely”, “sometimes”, or “regularly” during the day.

    The results of the study also differed depending on the age of the participants. Respondents younger than 60 years old who usually napped during the day had a 20% higher risk of developing high blood pressure than people of the same age who never napped during the day. At the age of over 60, this risk was increased by 10%.

    The study also showed that a higher percentage of people who usually took a nap during the day were men. What's more, they reported cigarette smoking, daily alcohol use, and insomnia.

    “While daytime naps are not in themselves harmful, many people sleep during the day because of poor nighttime sleep. Poor sleep at night is associated with poor health , however, daytime sleep is not enough to compensate for this, “explained scientist Michael A. Grandner from the University of Arizona.

    However, it is worth noting that the study has several limitations. It looked at nap frequency, not duration. The frequency of daytime sleep was also self-reported by the participants, with no specific measurements. The people who participated in the study were mostly middle-aged and elderly of European origin, so the results cannot be generalized to everyone.
