Lack of sleep for a long time hurt these five parts most

The research published in the proceedings of the National Academy of Sciences of the United States by the University of Surrey in the United Kingdom found that if you sleep less than 6 hours every night for a week, there will be changes in the functions of 711 genes in the human body, which involve metabolism, inflammation, immunity, compression and other functions. Insufficient sleep can also disturb the biological clock and make people’s mental state unstable throughout the day. This means that lack of sleep will hinder the body’s supply function and increase people’s risk of illness. Once the normal sleep pattern is continuously destroyed, it will cause permanent damage to human organs and physiological tissues and cause a variety of diseases.

First of all, the most obvious effect of lack of sleep on the human body is emotional instability and inattention. Especially for those who stay up late, the sympathetic nerve remains excited at night, and in the daytime, they will be listless, dizzy, poor memory, slow reaction, etc. over a long period of time, they will also have problems such as neurasthenia and insomnia. Luo Youlun, a physician at Chang Gung Memorial Hospital who specializes in sleep problems in Taiwan, said that generally speaking, people are most vulnerable to sleep debt at 4-5 a.m. and 2-3 p.m., because this is the lowest point of the biological clock and the stage when we are most powerless to resist sleep. Many major accidents and traffic accidents occur at this time.

Secondly, when sleep debt accumulates to a certain extent, it will cause serious harm to the body, including dry, dark and dull skin; Hearing loss, deafness and tinnitus; Loss of appetite and obesity; Gastric mucosal erosive ulcer; The incidence of heart disease, cold and other diseases increases.

Finally, good sleep quality is the key to longevity. According to a survey by the American Cancer Association, people who sleep an average of 7-8 hours a night live the longest; 80% of those who sleep an average of less than 4 hours a night are short-lived.

Guo jueheng, director of the sleep and respiratory disease diagnosis and treatment center of Beijing Chaoyang Hospital, pointed out that the best sleep time for different age groups is different. The elderly over 60 years old should sleep 5.5 ~ 7 hours a day; Adults aged 30 to 60 should sleep about 7 hours a day; Young people aged 13 to 29 should sleep about 8 hours a day; Children aged 4-12 years should sleep for 10-12 hours every day; Children aged 1 to 3 should sleep 12 hours every night and 2 to 3 hours during the day; Under the age of 1, 16 hours of sleep is required every day.
