Napping can help relieve fatigue, rest the body, and increase physical strength. However, if the time of the nap is not properly controlled, the sleep effect will be greatly reduced, especially the nap without the concept of time, too much sleep during the day, and the result is counting sheep at night. Such a vicious cycle will cause more damage to the body.
The lunch break should be kept at about 30 minutes, and the longest time should not exceed 1 hour. Appropriate nap can reduce stress and improve work efficiency. But siesta is just a "gas station" to let the body rest, and do not affect the quality of sleep because of the long siesta time.
The best time to take a nap is around 1pm after lunch, and rest until 1.30pm, which is enough to maintain the energy in the afternoon. After 3pm, it is not advisable to take a nap again, otherwise when the time to sleep at night is real, the body lacks the "demand" for sleep, which leads to insomnia, and long-term insomnia is not worth the effort. The elderly should pay special attention to this point.
Under normal circumstances, it is best to sleep at 11pm, get up at 7am in the morning, and start a lunch break at around 1pm, even if you do n’t have to go to work or on vacation.
