The positive effects of afternoon napping are widely known, as they can boost mood, reduce tiredness, and enhance alertness. However, it is important to consider the optimal duration of these naps. A recent study published in the May 2023 edition of Obesity suggests that keeping midday naps under 30 minutes is ideal for maintaining good health.
The study involved 3,275 individuals who were in good health. Baseline health assessments were conducted, and participants completed a questionnaire regarding their napping habits as well as other lifestyle factors such as diet and sleep patterns. The findings revealed that individuals who took midday naps lasting 30 minutes or longer had higher body mass index, cholesterol levels, blood sugar levels, and blood pressure compared to those who did not nap. On the other hand, participants who had shorter naps, lasting less than 30 minutes, did not exhibit these risks and were even less likely to have elevated blood pressure compared to non-nappers.
Researchers suggest that the increased health risks associated with longer naps may be due to disruptions in circadian rhythms, which can lead to insulin resistance, obesity, and metabolic syndrome. Another possible explanation could be overeating, as many individuals who napped for more than 30 minutes reported feeling hungry and craving sugary foods after their naps.
