Limited by the location of the nap, most people basically choose the "national common posture"-lying on the table, but that kind of nap posture is difficult to relieve fatigue. On the one hand, lying down for a nap is inevitable, which easily leads to poor blood flow in hands and feet, nerve damage and numbness in limbs; On the other hand, lying down for a nap shows obvious curl, but it will squeeze the cervical spine and spine, endanger the blood supply to the head and cause dizziness. Therefore, mastering the appropriate nap posture can reflect the real use value of nap!
The best way to take a nap in the afternoon is to lie down and fall asleep. However, many wage earners and students are limited by conditions and can only take a nap at their desks. But in fact, this kind of sleeping position is very easy to make their heads and necks stretch forward, and their fatigue will expand. Moreover, it will violate the structure of the human body system for a long time, leading to the cervical vertebrae leaning forward, which is detrimental to beauty and elegance. Sleeping on your stomach will also make your arm blood night not circulate, leading to pain, numbness and long-term coma. If your arms are numb because you are sleeping on your stomach, you can do more "spine-clamping" postures after a nap, that is, put your hands behind your back, then pull up Shen and return to the original point, for a group of ten seconds, three times in a row. Ridge-clamping posture can not only reduce arm numbness, but also stimulate body muscles and bones, which is very beneficial.
Many people also like to sleep in a chair with their heads up, but in fact, sleeping with their heads up is also very easy to scratch the shoulder muscles and squeeze the aortic nervous system around the cervical vertebra. Over time, there will be insufficient blood supply to the brain, which will lead to mental fatigue, fatigue, inattention, dizziness and tinnitus. So for sleeping posture, if the standard is enough, you can buy a stool that bends and stretches at will, or you can put a U-shaped pillow on your head and neck, which can relax and adjust your body muscles.
Many people feel uncomfortable after a nap. At this time, they can stand up and walk, pour a glass of water, and then drink it. The purpose of drinking water during a nap is to replenish water in the body, improve blood volume, and then dilute blood at night and maintain capillaries. But it must be noted that drinking water does not require overeating and drinking too much. Drinking too much water can easily make the inside and outside of the body cells wet. When people wake up from a nap, their brains will be temporarily short of blood supply, so that some people often have dizziness, nausea and vomiting, fatigue and other symptoms after waking up.
