A proper nap is of course hugely beneficial, but a bad one is also harmful. Does everything have two sides?
Busy work, nervous rhythm, often make people powerless, accordingly, the afternoon nap became the important guarantee of a lot of people’s work a day. The expert thinks, siesta not only can enhance physical strength, eliminate fatigue, improve the working efficiency in the afternoon, still have the effect that enhances airframe protection function at the same time. But there are a lot of attention to the nap, only a reasonable nap method to achieve the best results.
First, don’t rush to take a nap after dinner. Many people used to sleep after lunch, and then the stomach was just filled with food, a large amount of blood flow to the stomach, blood pressure dropped, oxygen and nutrition to the brain decreased significantly, immediately fall asleep will cause insufficient brain blood supply. Therefore, it is best to be active for 10 minutes before taking a nap so that food can digest.
Second, pay attention to sleep time. People generally think that as long as you sleep at noon, you can achieve the effect. However, experts say people are most likely to fall asleep either eight hours after waking up or eight hours before going to bed at around 1pm. Because at this time people’s vigilance is in a natural decline, at this time the body will get a good rest.
Three is to nap to pay attention to health. Don’t eat too greasy food or too full before going to bed, because greasy food will increase blood viscosity and aggravate coronary artery disease, and too full will increase gastric digestion burden. In addition, after waking up, you can drink a glass of water to replenish blood volume and dilute blood viscosity, and then you can have some light activities of walking.
Four is the nap should not be too long. Experts believe that a healthy nap of 15-30 minutes is the most appropriate, the longest should not exceed an hour. If the time is too short to achieve the effect of rest; If the time is too long, you will feel a slight headache and general weakness after waking up, and it is not easy to wake up.
Fifth, don’t sleep on your stomach. It is understood that most people do not pay attention to the nap position, some prone, some flat on the table to sleep. In fact, lying down to sleep will reduce blood supply to the head, so that people wake up after dizziness, dizziness, fatigue and a series of symptoms of cerebral ischemia and hypoxia. At the same time, using the hand as a pillow will cause eyeball compression, over time easy to induce eye disease, and lying on the table will compress the chest, affecting blood circulation and nerve conduction.
