5 More than 30 minutes of napping time is a bit long, but it is not good for health. If you take a nap for more than 30 minutes, your body will fall into a deep sleep, and if you wake up after about 45 minutes, you will not be able to complete the entire sleep cycle, causing headaches and other uncomfortable symptoms. If it is longer than 30 minutes, it is recommended to extend the nap time to 1 hour to complete the entire sleep cycle.

Taking a nap for 1 or 2 hours at noon can relax and rest the brain and various systems of the body, improve the body's immune function, and enhance the body's ability to resist diseases. Naping is a good way to promote health, but it is also necessary to pay attention to science, otherwise it will be counterproductive.

Therefore, there are five things to pay attention to when taking a nap:

1. Don't eat anything too greasy before going to bed, and don't overeat. Because oiliness will increase the viscosity of the blood and aggravate coronary artery disease; Being too full can increase the burden on the stomach to digest. Many people are accustomed to going to bed after lunch, when the stomach is just filled with food, a large amount of blood flows to the stomach, blood pressure drops, and the oxygen supply and nutrition to the brain drop significantly.

2. It is best to control the nap time within half an hour, otherwise it will be very uncomfortable to wake up. Taking too long a nap can also disrupt the biological clock and affect the regularity of sleeping at night.

3. Although taking a nap is to take a nap, it must not be too casual, do not sit or lie on the table to sleep, which will reduce the blood supply to the head and make people wake up with symptoms of cerebral ischemia and hypoxia such as dizziness, dizziness, and fatigue.

If you use your hands as a pillow, your eyes will be compressed, and it is easy to induce eye diseases over time, and lying on the table will compress your chest, affect blood circulation and nerve conduction, and make your arms and hands numb and tingling. The ideal nap position is one that lies comfortably, flat or on your side, preferably with your head high and your feet down, facing your right side.

4. No matter how hot the weather is, you should also cover your abdomen with a little towel quilt or quilt when you take a nap to prevent the cool air from entering.

5. Do not take a nap in a place where there is a wind or tuyere. Because the function of the thermoregulatory center decreases during sleep, the mild ones will feel unwell after waking up, and the severe ones will get sick from the cold.
