The habit of sleeping for an hour or 30 minutes after lunch has been found to boost brain activity in older adults. The researchers behind this finding believe that a nap in general in the afternoon can keep the brain five times younger.

According to the Daily Mail, the study involved more than 2,000 Chinese adults who were older than 60 years. More than 50 percent of the participants in the study reported that they took naps everyday after lunch for 90-30 minutes.

Dr. Junxin Li, one of the researchers behind the study, explained that those who did not take a nap or took shorter naps also experienced a decline in their mental capabilities
