Let me give you the authoritative answer! Sleeping on the table is a student’s exclusive right. Let me tell you what symptoms it will cause. First of all, numbness in the upper or lower limbs, like standing up after squatting for a long time. The feeling is the same. This kind of numbness is usually accompanied by weakness. When it is severe, you can't stand up or hold a pen. This is caused by poor blood circulation and long-term lack of oxygen in the muscles. If you are sleeping, you will definitely feel uncomfortable. Go to sleep to adjust. If this happens in a coma, it is likely to cause limb necrosis. Basically everyone has encountered this situation, so there is no need to worry. It’s a purely mobile phone call, which is the best!
