Why do college students sleep on their desks when they are in class?

Personally, I think that the phenomenon of college students sleeping on their desks in class is mainly because college students often stay up late to play games, do not take their studies to heart, ignore the university courses, and at the same time, the university teachers are not so strict.

Because college is more relaxed, teachers can't be as strict as high school Second, after college, children are more relaxed.

Because college students often stay up late at night to play games, they don't pay attention to their studies at all, and they also ignore the courses during college, so this phenomenon will occur.

That's not good.

1. Sleeping on the table during the nap will affect digestion, many students sleep on their stomachs after lunch, this is not good, just after eating, the human stomach needs a lot of blood to support food digestion, if you sleep on your stomach, sleeping on your stomach will aggravate the ischemia of the brain, and eventually lead to dizziness, tinnitus, soft legs and numbness and other symptoms. So it's better to lie down and sleep.

2. Sleeping on the stomach also affects breathing, because sleeping on the stomach and the body is bent, so that the chest breathing is not so smooth, especially for women. This affects oxygen**, which can lead to damage to the brain, for example.

3. Sleeping on your stomach will also lead to various problems, such as small problems such as not being good for your eyes and easy paralysis of your arms, but these small problems will always evolve into other problems, so you still need to pay more attention to these small problems in life in order to have a good body.

It is recommended that you better stay in bed as well, so that the blood circulation is not good

Weak legs and numbness in the feet caused by cerebral ischemia Often sleeping on the table causes harm to health: 1. Affect breathing. Due to the increased curvature of the body due to the sleeping position on the stomach, the breathing is not smooth, and the oxygen in the body will naturally be insufficient.

Postures that compress the chest can also induce various heart diseases. Second, the sleeping posture will press the eyeballs, and the eyes are easy to be congested, resulting in an increase in intraocular pressure, and temporary blurred vision often occurs after waking up, especially for people with high myopia. 3. After falling asleep, the heart rate will gradually slow down, the blood flow through various tissues will also slow down, and the blood flowing into the brain will be less than usual.

After lunch, more blood enters the gastrointestinal tract to help digestion, and sleeping on the stomach will aggravate the ischemia of the brain, which will eventually lead to symptoms such as dizziness, tinnitus, and numbness in the legs and feet. 4. If the head is pillowed on the arm for a long time, the blood circulation of the arm is blocked, the nerve conduction is affected, and it is easy to have symptoms such as numbness and soreness in the arm. 5. Affecting digestion, most people eat more at lunch, and it takes about 3 hours to digest these foods.

Taking a nap on the table after eating lunch is easy to cause stomach bloating. Sixth, lying on the table to sleep is generally not clothed, and after people fall asleep, the basal metabolism of the whole body slows down, and the body temperature regulation function also declines, resulting in a decrease in the body's resistance, and the pores of the whole body are in a state of opening. If you don't pay attention to keeping warm, you will often experience symptoms such as nasal congestion and dizziness after waking up.

7. In addition, sleeping at the desk can not make the body completely relaxed, and some muscle groups, sweat glands, and ** of the body will still be in a state of tension, resulting in not only no feeling of full energy after sleeping, but may feel more tired on the contrary.

Hazard 1: Students are afraid of sleeping on the table mainly lying on the arm, which is easy to compress part of the nerves on the arm for a long time, and the nap time is not long, many students are very anxious to seize the time to sleep.

Hazard 2: Students sleeping on the table will also compress many nerves in the eyes, including the eyeballs, and temporary blurred vision usually occurs after napping.

Induce chronic diseases of heart and cerebrovascular.

Induce cervical spine and spine diseases, induce respiratory diseases, induce elbow ulnar nerve disease, and damage the eyes are normal. This kind of temporary eye discomfort can be obtained through conditioning, but if you often take a nap at the desk, the eyeball is often squeezed abnormally, which will lead to irreversible eye hazards, and even the focus can not be gathered when working at close range, and eye abnormalities such as rainbow-like halos appear when looking at lights. In addition, long-term squeezing of the eyeball by the arm can also lead to a decrease in the curvature of the cornea.

The cornea is an important part of the eye's refractive system, and when it is deformed, it can lead to changes in refraction and blurred vision. 3. Avoid excessive intraocular pressure.

Outdoor activities can increase the oxygen supply to the blood vessels in the fundus, which can avoid the increase in intraocular pressure. Do not work in the dark for too long, as this will dilate the pupils and increase intraocular pressure. As long as you sleep on your stomach, you can't keep your hands from going numb unless you change your sleeping position.

Because some of them don't understand or the students are not interested in listening to it during class, they can't do anything during class except play with their mobile phones, but they can't play with their mobile phones casually, so they have to sleep.

College students like to sleep in class are also cultivated later, but in fact, this is not the case at the beginning. When I first entered the university, I was more active in the class to listen to the lectures, that is, I left the high school classroom habits to listen to the lectures, and the learning efficiency and habits at that time were very high, and they were all very obedient students, that is, sometimes the more sleepy students dozed off and would not sleep on their stomachs, and when they got out of class, they had already fallen down a large piece, or they would directly make up for it in the dormitory when there was no class.

After adapting to a period of actual college life, I feel that there are more people who sleep, and sometimes when I see the seniors in class, I find that I sleep a lot, and the teacher will not pay too much attention to it. At that time, our atmosphere followed, and the students gradually listened to the class and became distracted, either many of them secretly played with their mobile phones, or they swaggered to sleep, and many teachers would not ask too much about your sleep, he was afraid of delaying the progress of the lecture.

After a period of trying, students sleep and play with mobile phones without listening to lectures without much problem and become accustomed to a lot, and the life of the university is colorful, how late you sleep at night will not restrain you, at that time your heart of play will be active, students often play very late, so that there is no *** sleep at night, the next day will definitely be sleepy, so when the class is in class, college students sleep more, life is maintained like this to form a regular sleep, in the eyes of others is like to sleep in class.

In fact, many people feel that they should sleep because they are not interested in what they are learning or do not understand what the teacher says.

The class is too boring, and the general teacher lectures are boring.
