? If there is an important dinner or activity in the evening, it may delay the time to sleep at night, so you can reserve sleep in advance in the afternoon. Taking a nap after lunch is a habit of many people. Office workers "replenish energy" for afternoon work, while retirees recharge their batteries. A few days ago, a study showed that taking a nap for half an hour before meals can effectively eliminate fatigue and greatly improve the efficiency of work and study in the afternoon. In this regard, scientists suggest that it is best to take a nap before meals instead of taking a nap in advance.

It is not advisable to sleep at the computer desk.

Taking a nap with hands instead of pillows has three major hazards.

Hazard 1: Because of sleeping on the arm, many nerves are oppressed, and they are often anxious and can't sleep during a nap.

Hazard 2: Temporary blurred vision usually occurs after a nap, because the eyeball is compressed when sleeping on your stomach. If this happens for a long time, the intraocular pressure will be too high. Over time, the eyeball will swell and the axial length will become longer, which will lead to high myopia and easily increase the incidence of glaucoma.

Hazard 3: Sleeping on your stomach and pressing your arms and face for a long time will affect normal blood circulation and nerve conduction, making your arms and face numb and even sore. After a long time, it will develop into local nerve paralysis or facial deformation.

? Intimate reminder: If you can't go home for a nap, try to lie down for a nap and don't sleep on your desk.

According to foreign reports, a study conducted by psychologists at Harvard University in the United States shows that a nap at noon can refresh the mind, and the effect is equivalent to sleeping for eight hours all night.

Napping is a scientific regulation of human biological clock, but there are also taboos:

1. Try to avoid taking a nap. It is best to control the nap time within half an hour, otherwise it will be very uncomfortable to wake up. If this happens, get up and exercise properly, or wash your face with cold water, the discomfort will soon disappear.
