Taking naps

Napping

Description

Certain cultures, particularly those in hot climates, have systematic nap times, or siesta. A 15- or 20-minute sleep in the day can for some improve alertness, sharpen memory and reduce the symptoms of fatigue. Some people may need more or less time. Humans are more likely to nap after lunch.

Implementation

Midday napping is a cultural practice in China and it is built into the after-lunch schedule in work and at schools.

Young adults who take a nap during the day perform better in school, according to a study published in the journal Behavioral Sleep Medicine by researchers from the University of Delaware and the University of Pennsylvania.

US President Lyndon B. Johnson was a dedicated napper who donned pajamas in the middle of the day and slept for half an hour.

Claim

Multiple short naps (between twenty and thirty minutes every four hours or so) can reduce total sleep to two or three hours in the 24 for weeks on end without detriment to a person's overall performance.

A nap is not a substitute for a full night's sleep; it is only a short-term solution. But it could spell the difference between life and death if you're sleep-deprived and planning on a long drive.
