The benefits of taking a nap

After lunch, it's a habit of many people. After working for the afternoon, the office worker “supples energy.” The retired people are nourished. A few days ago, studies showed that: Taking a half-hour nap before meals and siestaing for 2 hours after a meal can effectively eliminate fatigue and greatly increase the efficiency of work and study in the afternoon. In this regard, scientists suggest that it is best to advance the siesta time --- to nap before meals.

"There is a certain truth in this argument, but don't put it in a hard-won way." Professor Fan Dongsheng, head of the Sleep Center at Peking University Third Hospital, told reporters. Why do people get dizzy after siesta? This is because after the meal, the blood flow to the gastrointestinal tract, resulting in the relative reduction of blood flow to the brain and limbs, the brain and limbs can not get enough oxygen and nutrient supply, lactic acid and other metabolites can not be discharged in time, wake up and feel Dizziness, limb weakness, whole body sore. Folks have the saying "sleep and intestines back". In particular, office workers often nap on the desk for a while, causing the chest to be oppressed, affecting the breathing, increasing the degree of hypoxia of the brain, and appearing physiological transient "brainemia." At the same time, the brain and the stomach and the stomach compete for blood and they often miss one another, causing the digestive and nervous systems to work hard. According to a study by German scholars, during the siesta after a meal, subcutaneous capillaries dilate, blood flow increases, and the blood flock to the digestive organs to fight blood with the brain. At this time, there is a danger of inducing cerebral embolism. Therefore, people who weigh more than 20% of the standard body weight, people with low blood pressure, and the blood circulation system have serious obstacles. People who are often dizzy because of cerebrovascular disease should avoid napping after meals.

This will eliminate fatigue more effectively and allow food to be fully digested and absorbed. People with poor gastrointestinal function should pay special attention not to sleep after meals. For people who are unwilling to change their sleep habits, they can do some minor activities after meals, take a walk, rub their abdomen for about 10 to 20 minutes, and then they can step down and relax. Office workers who are busy with work, if there is not enough nap time before meals at noon, after the meal is over, you can lie back in your chair and take care of your eyes for a moment. Try to relax your belt so that your brain and stomach can be fully rested. It should be noted that the nap time should be controlled within 15 to 30 minutes and it should be within 1 hour. If it exceeds this limit, from shallow sleep to deep sleep, it is not only difficult to wake up, but also wake up. Mild headache or general feeling of weakness.
