Five hazards of staying up late:
First, it is easy to cause immune dysfunction.
Professor Chen Yujie from the Respiratory and Sleep Department of Sichuan Fourth People's Hospital said: "Dark circles and mental fatigue are only superficial symptoms caused by staying up late. In fact, the more terrible harm of staying up late for a long time is the disorder of the body's immune function, nephritis in the kidneys, lupus erythematosus in the skin and rheumatoid arthritis in the joints.
At the same time, the body's immune ability will also be reduced, making the human body in a serious sub-health state, and respiratory diseases such as colds and gastroenteritis will come to you.
Second, it leads to high blood pressure and even sudden death.
Jiandong Ding, chief physician of the Department of Cardiology, Zhong Da Hospital affiliated to Southeast University, said: Studies show that long-term lack of sleep is an important pathogenic factor of hypertension, which greatly increases the probability of people staying up late suffering from various sudden cardiovascular and cerebrovascular diseases, and even leads to sudden death.
Remedy: Patients with hypertension must pay attention to the quality of sleep and try to avoid staying up late at ordinary times, especially those with congenital heart disease and elderly hypertension.
Third, people who stay up late are more likely to get cancer.
Medical research shows that people who stay up late are more likely to get cancer than those who sleep normally. Take pancreatic cancer as an example, the incidence of people who often stay up late is more than three times higher than the average person. Because cancer cells are produced during cell division, and cell division is mostly carried out during sleep. Staying up late will affect the normal division of cells, leading to cell mutation and cancer cells.
Fourth, staying up late for a long time will hurt your eyes.
Staying up late is not only harmful to eyes. Overloading the eyes for a long time will cause problems such as eye pain and dryness, and even make people suffer from dry eye. In addition, eye muscle fatigue can also lead to temporary vision loss. Overwork caused by staying up late for a long time may also induce central retinitis, leading to a sudden drop in vision.
Five, cause neurasthenia, headache and insomnia.
People's sympathetic nerves should rest at night and be excited during the day, so as to support people's work in the day, while people who stay up late are excited at night.
During the day after staying up late, it is difficult for sympathetic nerves to be fully excited, which will make people listless, dizzy, memory loss, inattention, unresponsiveness, forgetfulness, dizziness and headache. After a long time, there will be problems such as neurasthenia and insomnia.
