Injury 1: deafness
Some people play online games all night, indulge in disco dancing in bars and play mahjong, which makes many people seriously lack sleep. However, lack of sleep can easily make blood vessels tense, leading to insufficient blood supply to the inner ear, which is extremely destructive to hearing, and staying up late for a long time may lead to deafness.
Injury 2: Obesity?
Anything eaten after 20 pm is called "midnight snack". There are two kinds of autonomic nerves in human body: sympathetic nerve and parasympathetic nerve. Sympathetic nerve makes the stomach run frequently during the day when the body is active, promoting digestion and absorption; At night, the parasympathetic nerve is active, allowing the ingested nutrients to be stored in the body at rest. If you eat at night, it will not only be difficult to sleep, but also make you lose your appetite the next morning. The resulting nutritional imbalance will lead to obesity.
Injury 3: skin damage?
Generally speaking, the skin enters the night maintenance state from 10 pm to 1 1 pm. If you stay up late for a long time, the normal circulation of human endocrine and nervous system will lose balance, and the disorder of nervous system will cause problems such as dry skin, poor elasticity, dull skin and lack of luster. Endocrine disorders can make skin, especially young people's skin, prone to acne, acne, chloasma, dark spots and other problems.
Injury 4: Memory loss?
Under normal circumstances, people's sympathetic nerves should rest at night and be excited during the day to support people's work and life in a day. The sympathetic nerves of those who stay up late are excited at night, so that people will have problems such as listlessness, dizziness, memory loss, inattention, unresponsiveness, forgetfulness, dizziness and headache during the day. After a long time, there will be problems such as neurasthenia and insomnia.
Injury 5: Gastrointestinal crisis?
The stomach is very sensitive and fragile, and staying up late is very harmful to the stomach, which can easily lead to acute gastroenteritis and gastrointestinal dysfunction.
If you often stay up late, you may have gastric ulcer, 12 duodenal ulcer, chronic atrophic gastritis, gastric cancer and other lesions. Need to be actively improved
This process is usually carried out during gastrointestinal rest at night. If you often eat at night, the gastrointestinal tract will not get the necessary rest, and the repair of gastric mucosa will not be carried out smoothly. Moreover, when you sleep at night, the supper you eat stays in your stomach for a long time, which can promote the secretion of gastric juice and stimulate the gastric mucosa. Over time, it is easy to cause gastric mucosal erosion and ulcer.
Injury 6: decreased immunity
If you are often in a state of staying up late, fatigue and listlessness, your immunity will decline, and symptoms of autonomic nervous disorders such as colds, gastrointestinal infections and allergies will come to you unexpectedly. Moreover, the direct symptoms caused by staying up late often are dizziness, inability to concentrate and even migraine when going to work the next day.
Injury 7: Heart disease risk
Staying up late often will lead to neuroendocrine dysfunction in our body. Sympathetic nerve fibers that dominate our heart are in a state of excitement for a long time, which will release too much catecholamine substances, which will accelerate our heart rate and increase our blood pressure, thus increasing the extra burden on the heart. Staying up late often will cause coronary vasospasm, vascular endothelial damage, and unstable atherosclerotic plaque, which will lead to insufficient blood supply and oxygen supply to myocardium, ischemia, hypoxia and even necrosis of myocardial cells, and even lead to sudden death of heart patients in severe cases. Staying up late often will also make our immunity decline and endocrine function disorder, especially organs like the heart, which will not be adjusted to staying up late because of rest during the day. Therefore, if black and white are reversed for a long time, the risk of heart disease will increase.
