Usually take more than ten minutes and then take a nap after eating.
3, sleeping posture should take the head high foot low, right side lying position. This can reduce the pressure of the heart and prevent snoring. It should be noted that sitting and sleeping on the desk will reduce head blood supply and make people wake up dizzy, dizzy, tired and a series of symptoms of cerebral ischemia and hypoxia. Some people use their hands as pillows and lie on the table for a lunch break, which will cause eyeball compression and will easily induce eye diseases over time. In addition, lying on the table will oppress the chest, affect respiration, and also affect blood circulation and nerve conduction, causing arms and hands to tingle and tingle.
4, during the nap, avoid strong external stimulation. Because of muscle relaxation, telangiectasia, and enlarged sweat pores after falling asleep, it is easy to catch cold or other diseases.
5, light activity after waking up. After a nap, you should stand up slowly and drink a glass of water to replenish the blood volume and dilute the blood viscosity. Do not immediately engage in complex and dangerous work, because early awakening often makes people feel trance.
