Regular afternoon naps — even of just five minutes a day — may improve your mental agility and help to stave off dementia, a study has reported.
Researchers from China studied the sleep patterns of 2,214 healthy adults aged 60 or over who lived in several large cities — including Beijing, Shanghai and Xian.
Of the participants, 1,534 reported taking a regular afternoon nap of between five minutes and two hours, while the remaining 680 individuals did not.
