The health advantages of taking a day nap are well documented. They can improve mood, reduce fatigue, and increase alertness. But how long should they last? A study within the May 2023 issue obesity suggested that the best duration is lower than half-hour.
The observational study involved 3,275 healthy adults. Baseline health was measured, and participants accomplished a questionnaire on their sleeping habits and other lifestyle aspects resembling weight loss plan and sleep. The results found that in comparison with individuals who didn't nap, those that took afternoon naps of half-hour or longer had higher body mass index and better levels of cholesterol, blood sugar and blood pressure. In contrast, those that took fewer naps (lower than half-hour) didn't share these risks and were less more likely to have elevated blood pressure than those that never napped.
According to the researchers, a few of these risks stands out as the results of long naps disrupting day by day circadian rhythms, which might result in insulin resistance, obesity, and metabolic syndrome (a cluster of conditions that increase the danger of heart disease, stroke, and diabetes). Another possible link may very well be overeating, as many individuals who slept longer than half-hour reported feeling hungrier and craving sweets.
Does it matter how often you sleep? All afternoon nappers, no matter how long they slept, averaged about 4 naps per week, however the researchers found no link between frequency and better health risks. So, enjoy your afternoon naps, but keep them to lower than half-hour, and do not sleep too late within the afternoon, as this may disrupt your night's sleep.
