The disadvantages of staying in bed Sleep is a life activity that the human body must carry out. According to foreign observation and measurement, teenagers have 6.5-8 hours of good sleep, and 965,438+0.7% people can get rid of fatigue and recover their physical strength. Many people think that sleeping more during the development period is beneficial to organ development and physical and mental health; Can enhance the biological activity of the body; People will grow taller and stronger. Japanese health experts point out that the above three concepts are all wrong, and they are often used by parents as the best reason to "protect" their children from sleeping late, so it is very harmful. A normal teenager who often stays in bed and gets up late (10 hours or more) will not increase his spirit, but will often cause the following six "complications". Obesity often stays in bed, but does not pay attention to a reasonable diet (eating a lot of meat and sweets). The other is not very active. Three-pronged approach, energy reserves will be greater than consumption, in the form of fat accumulated under the skin. It only takes about a year and a half, and you will find yourself a little fat. Obesity does not subside, and the potential harm is not shallow. Epidemiological surveys in Europe and America have found that diseases such as heart disease, hypertension, mastopathy, diabetes, and limb deformity in adulthood are all related to teenagers' bad living habits, among which eating disorders and sleepiness account for a certain proportion. Therefore, teenagers with obesity trend must give up sleepiness more, while they are still in the shaping stage, cooperate with exercise, dieting and other methods to restore their vigorous figure and good mental outlook, and don't let themselves become a little fat man who loves to sleep late. In addition, some people find that lying in bed can also make people wander aimlessly. After getting up, I feel top-heavy, weak, upset and don't want to do anything. According to the analysis, this may be because "using the brain" in bed consumes a lot of energy elements such as oxygen, blood sugar, protein and lecithin. , make the brain tissue appear temporary "malnutrition", can't work normally. Breaking the biological clock effect, traveling by plane across time zones, especially to Europe and America, often leads to dizziness, insanity, rapid heartbeat, lack of food, fatigue and other symptoms when you first arrive in a certain place. If you are an athlete, it will often affect your performance. Are you sick? No, it's just the so-called jet lag. Joking with the body is the difference in space distance and time, which is related to the fluctuation of hormones in the body. Let a person on the day shift take a hormone test. The results show that the concentrations of many hormones secreted by hypothalamus and pituitary gland are relatively high from morning to night, but relatively low from night to dawn. The middle and late shift workers are the opposite. If you live a regular life, but sleep late on holidays, it will disrupt the timing of the biological clock in the body and make the hormone level fluctuate abnormally. As a result, the hormone level can't go up during the day and can't fall down at night, which makes people sleepy at night, fidgeting and exhausted during the day. It can be seen that the secretion of hormones is very regular and closely related to people's living habits. Bad living habits, especially sleeping habits, will inevitably disrupt the normal work of endocrine and directly affect people's behavior. Generally speaking, a moderate dinner is basically digested around 7 am the next day. At this time, the gastrointestinal tract began to move according to the body's "hunger" information, ready to accept and digest new food. However, those who lie in bed lose their appetite because of comfortable sleepiness, preferring to have an empty stomach rather than get up to eat. Day after day, due to the frequent occurrence of hunger and peristalsis in gastrointestinal tract, the integrity of mucosa is destroyed, and diseases such as gastritis, ulcer and digestive and absorption dysfunction are prone to occur. Low muscle tone. After a night's rest, muscles and joints usually become more relaxed in the morning. If you get up immediately after waking up, on the one hand, you can increase the tension of muscle tissue to adapt to daytime activities. On the other hand, through activities, the blood supply of muscles is increased, muscle tissue is in an active repair state, and metabolites accumulated in muscles at night are discharged. This is beneficial to the thickening and toughening of muscle fibers. People who only care about staying in bed often feel weak legs, lumbosacral discomfort and limb weakness after getting up because they missed the opportunity of activities. People who don't know the truth think they didn't sleep well and plan for the next day's lie-in. Compared with foreign sports anthropologists, the muscle tension of teenagers who get up late is often lower than that of ordinary people. In other words, people who lie in bed have insufficient muscle explosive force and slow action response. The air in the bedroom is the most turbid in the morning. Even if the windows are not locked, 23% of the air cannot be circulated and exchanged. You will be surprised if you take samples from the local area. The air contains a lot of bacteria, mold and fermentation particles, carbon dioxide, moisture and dust. It goes without saying that these unclean ingredients will bring trouble to the body. No wonder those who sleep with the windows closed often have colds, coughs, sore throats and dizziness. In addition, high concentration of carbon dioxide will stimulate the respiratory center, making people uncomfortable to breathe. Some people think that frequent carbon dioxide poisoning may reduce memory and hearing. When teenagers are in good health, about 96% of the tissues and organs are still under construction, so we should take good care of them. Lying in bed is an unsanitary living habit and trampling on one's body and mind. It kills time and wastes valuable fitness and morning study time. It is really a stumbling block that hinders the healthy development of teenagers in all aspects. We should consciously resist it for a long time.
