nap It’s one of the many activities that people engage in out of habit, especially when they need to finish their workdays or “replenish energy” to stay active for the rest of the day. However, a study from the Sleep Medicine Clinic at Banner University Medical Center in Tucson, USA, published in the journal Hypertension, concluded that the habit could be harmful to your health.
Who would imagine that napping before the usual time would cause problems like high blood pressure? According to Michael Grandner, a researcher who directs the sleep medicine clinic at Banner University Medical Center in Tucson, there’s a reason people tend to have high blood pressure.
What does the study say about napping?
Information from 360,000 people was used for this research, which consisted of analyzing nap duration but not frequency. It was then found that participants who took naps during the day were 12% more likely to have high blood pressure and 24% more likely to have a stroke than those who never slept.

On the other hand, people under 60 who napped were 20% more likely to develop high blood pressure, they revealed in the American Heart Association’s journal Hypertension.
The study excluded people with type 2 diabetes, pre-existing high blood pressure, high cholesterol, sleep disorders and night workers.
How long should a nap last?
according to dr Raj Dasgupta, a sleep specialist and associate professor of clinical medicine at the Keck School of Medicine at the University of Southern California, a nap needs to be long enough to help you recover from fatigue.

“For example, if you sleep an hour, two hours, that’s not really a nap. A 15-20 minute power nap between 12pm and 2pm is 100% right if you are sleep deprived. If you suffer from chronic insomnia, we don’t recommend napping as it discourages you from sleeping at night,” he explained.
