Hour Long Naps Shown to Improve Thinking in Older Chinese Adults

A recent study among nearly 3,000 Chinese adults aged 65 and older, discovered important benefits from taking an afternoon nap.

The finding is important given the demographic transition toward an older population where preserving memory, as well as the ability to think clearly and make decisions, becomes a key goal.

Researchers have a growing interest in the role sleep plays in helping older adults maintain their healthy mental function.

The recent study, “Afternoon Napping and Cognition in Chinese Older Adults: Findings From the China Health and Retirement Longitudinal Study (CHARLS) Baseline Assessment” appears online, ahead of print in the Journal of the American Geriatrics Society.

Nearly 60 percent of the people in the study said they napped after lunch in the afternoon. They napped between about 30 minutes to more than 90 minutes, with most people taking naps lasting about 63 minutes.

The participants took several tests to assess their mental status. They answered simple questions — such as questions about the date, the season of the year, etc. — and they did some basic math problems.

Participants also were asked to memorize and recall words, and were asked to copy drawings of simple geometric figures. Finally, these older Chinese adults were asked questions about their napping and nighttime sleep habits.

According to the study’s results, people who took an hour-long nap after lunch did better on the mental tests compared to the people who did not nap. Those who napped for about an hour also did better than people who took shorter or longer rests.

People who took no naps, short naps, or longer naps experienced decreases in their mental ability that were about four-to-six times greater than people who took hour-long naps.

The people who did not nap, and those who took shorter or longer naps, experienced about the same decline in their mental abilities that a five-year increase in age would be expected to cause.
