A 2016 study published in the Journal of the American Geriatrics Society found a link between napping 30 to 90 minutes after lunch and improved cognitive function.

The research included analysis of self-reported data on napping from 2,974 people in China, aged 65 years and older.

Participants were divided into groups: no nap, short nap (less than 30 minutes), moderate nap (30 to 90 minutes), and extended nap (more than 90 minutes).

Attention, episodic memory and visual-spatial abilities were assessed, and those who took moderate naps performed better overall, while those who did not take naps showed poorer cognitive abilities than those who took short naps.

This study is just one of many that have looked at the benefits and drawbacks of daytime napping.

Interestingly, science seems divided on how beneficial napping is for your brain. For example, a 2022 study linked napping during the day to an increased risk of Alzheimer's disease, while a 2021 study found that napping for less than 30 minutes reduces the risk of developing Alzheimer's disease. Alzheimer's disease.

While some may swear they need a nap to keep their energy levels steady throughout the day, others say that taking a quick nap leaves them feeling sluggish afterwards.

If you rely excessively on napping, you may not sleep well at night, or you may have an underlying health condition that requires seeing a doctor.
