Therefore, siesta is a scientific regulation of human biological clock. Not all naps can achieve the purpose of rest. We should pay attention to the following points:
A taboo:
The longer the nap, the better.
It is advisable to take a nap for half an hour to one hour. If you sleep too much, you will feel uncomfortable after waking up because you have fallen into a deep sleep. If this happens, get up and exercise properly, or wash your face with cold water and drink a glass of water, and the discomfort will soon disappear.
Two bogeys:
Take a casual nap.
You can't just lie down and sleep in the corridor, under the shade, on the grass, on the concrete floor, and don't take a nap in the draught or on the tuyere. Because people's body temperature regulation center function declines during sleep, the severe ones catch a cold, and the light ones wake up unwell.
Three bogeys:
Sit or lie down and take a nap.
Because of the limited conditions, many people sit or lie down at the edge of the table during lunch break, which has long formed the habit of sitting or lying down during lunch break, which is extremely unfavorable to their health. Taking a nap at the edge of the table will oppress the chest, affect breathing, numb the arms, and even fail to adjust the body.
Four bogeys:
Everyone needs a nap.
Not everyone needs a nap. As long as they are healthy and get enough sleep at night, not taking a nap will generally not affect their health. But for people engaged in mental work, primary and secondary school students, the weak or the elderly, a nap is necessary.
Do not take a nap for more than 30 minutes.
