Many white-collar workers or students cannot go home or back to the dormitory at noon, so they will just lie down on their seats for a nap. When they wake up, they often see things blurry, and sometimes they have neck pain, numbness in their hands and feet. So what's going on? I fell asleep on the table and woke up to find that I couldn't see clearly. Why?I lay down to rest at noon and woke up with blurry vision. This may be due to the following reasons: 1. Insufficient blood supply. In this case, the blood supply to the brain and eyes may be insufficient, and temporary blurring may occur. 2. Corneal deformation. Sometimes, the cornea is deformed due to external forces. After a period of time, the cornea will be deformed, so blurriness will occur, but the cornea will quickly return to its original state. 3. Increased intraocular pressure. Long-term pressure on the eyeball will cause the anterior chamber to become shallower, affecting the circulation of aqueous humor, causing increased intraocular pressure and possibly leading to glaucoma. Therefore, during lunch break, try not to use the digging method. If there is no other way, avoid pressing on the eyeballs! What to do if your neck hurts when you sleep on your stomachWhen you sleep on your stomach, your eyeballs are compressed, and the muscles in your neck are in a twisted state. The neck muscles become stiff, which causes the neck blood vessels to become thinner and induces insufficient blood supply to the brain. That's why you have blurred vision when you wake up. Numbness in your hands is also due to poor blood circulation and the lack of nutrition for the nerves, resulting in temporary numbness. This numbness will disappear when you move around, and the neck pain will slowly ease by getting up and moving around. Therefore, this phenomenon is temporary. Blurred vision will improve when the blood supply to the brain is improved, and numbness in the hands will also be relieved when the blood circulation is smooth. It is recommended that people who often need to lie on the table to rest should prepare a pillow to sleep with. This is more conducive to protecting the cervical spine and preventing blurred vision and numbness in the hands. Why do I drool when I sleep on my stomach?Whether you are lying on the table, sleeping on the bed, or sleeping on your side, it is easy to drool. The reason is that when the face is facing down, the cheek is close to the table or pillow, the saliva is squeezed and secreted from the inside of the mouth, which is called saliva outflow. In addition to improper sleeping posture, tooth deformity or oral problems, this is also one of the causes of drooling. Oral inflammation, such as oral ulcers or caries, periodontitis, etc., can cause increased saliva. In this case, drooling usually has color and odor. Additionally, when a person is overtired or overexcited, autonomic dysfunction may result in false signals to the brain during sleep, leading to increased saliva production. |
