A netizen asked: During breaks at work every day, I will take a nap for more than an hour to recharge my body. However, every time I wake up, I am not as refreshed as I imagined, but feel more tired the longer I sleep. What's going on? My god, which construction site are you working on? You can actually take a nap for more than an hour at noon. I envy you so much~ Just kidding, let’s get down to business. A nap can be described as a "repair agent" for the body. Taking a nap after lunch will make you feel refreshed in the afternoon. However, we need to remind you that there are many things to pay attention to when taking a nap, and you can't just take a nap casually. In particular, the length of the nap and the sleeping posture must be taken seriously. Let’s talk about the length of the nap first—— Generally speaking, a half-hour nap is best, but not too long. This is because people usually enter the deep sleep stage half an hour after falling asleep. At this time, the central nervous system is in the stage of inhibition. The blood flow through the brain tissue is relatively reduced. At the same time, the human body's muscles are in a relaxed state, and the metabolic process in the body is also relatively reduced. If people wake up at this moment, the inhibition of their cerebral cortex has not yet been lifted, and they are prone to symptoms such as general discomfort, dizziness, and fatigue. Therefore, the nap time should not be too long, about 20 to 30 minutes is appropriate, that is, before entering the deep sleep period. After reading this, you should know why you feel more tired the more you sleep! Let's talk about the nap posture - First of all, everyone should avoid sleeping on the table. Sleeping on your stomach, especially with your arms as a pillow, will not only affect blood circulation, cause numbness and tingling in your arms and hands, make your neck and waist muscles tight and sore, but also put pressure on the stomach and easily cause bloating. In addition, people who sleep on their stomachs are prone to symptoms of cerebral ischemia and hypoxia, such as dizziness, blurred vision, and fatigue after waking up. In fact, the most ideal nap position is lying down. For office workers who have the conditions, it is recommended to buy a folding bed or a folding recliner and sleep on it, so that the whole body can be effectively relaxed. If conditions do not permit, you can sleep leaning against the back of a chair. It is recommended to place a cushion behind your waist, a U-shaped pillow on your neck, and make the chair back as flat as possible, so as to reduce the pressure on the cervical and lumbar vertebrae. |
