For modern white-collar workers, working overtime and staying up late is a very common thing. Because of the huge work pressure, the sleep quality has declined dramatically. Recently, a survey found that lack of sleep actually affects human DNA and has cancer risk, so it's better to stay up late for your own health!
According to a recent article in Taiwan's Zhongshi electronic news, sleep is an important part of the life cycle, and people usually need to sleep for eight hours. The research points out that sleep deficiency can cause blood glucose disorder. If people are greedy for food, it may affect human genes, and then develop into chronic diseases. At the same time, sleep is also closely related to mental and emotional aspects, and it is easy to fall into depression if you do not sleep well.
BBC Documentary believe me, I'm a doctor has proved by experiments that sleeping less than an hour a night can affect about 500 genes in the human body, which may lead to cancer or diabetes if the changes are serious.
The BBC is also working with Oxford University to study the relationship between sleep and mood. The team called four volunteers to sleep for eight hours in the first three nights and only four hours in the second three nights. They were monitored with instruments and asked to answer the mental and emotional rating scale.
The study found that, for three consecutive days of sleep deprivation, the mood of volunteers changed, anxiety, depression and stress indicators showed an upward trend, and they began to have a tendency to be suspicious, even positive emotions decreased, negative thoughts increased, although I may not feel it.
According to Freeman, a psychology professor at Oxford University, lack of sleep can interfere with the brain because of its constant negative thinking. That is to say, if sleep quality is not good, negative thoughts will increase.
All in all, improving sleep quality can further improve people's overall health and well-being.
What are the hazards of staying up late often?
1. It may cause heart trouble. In modern society, life is fast-paced and stressful, especially for people living in the city, many people ignore sleep for work, study, entertainment and other reasons, but these behaviors bring many hidden dangers to the heart. Recently, according to a survey, 40% of the respondents often stay up late, 26.67% often suffer from insomnia, 73.33% of them are "late to bed and early to rise". Recently, sudden death often occurs, mostly because of continuous staying up late to work, resulting in cardiac overload operation, coupled with the usual inattention, resulting in sudden cardiac death.
2. Gastrointestinal damage. 'it's shameless not to sleep at 11:00 p.m. and it's not fatal not to sleep at 12:00 p.m.', as many people know, but they can't do it. Long term 'black and white reversed' people, not only bad temper, viscera can not be adjusted in time, so that the risk of heart disease increased. At the same time, it will also cause deafness, tinnitus, headache and gastrointestinal diseases. When sleeping, it is the best rest time for the body organs. People who often stay up late will have the habit of eating midnight, and eating midnight will increase the burden on the gastrointestinal tract, so that neither the liver nor the gastrointestinal tract can rest. Over time, the gastrointestinal tract must have problems.
3. Liver damage, dark complexion and unhealthy skin. We can find that people who often stay up late must have dark skin and may have acne. That's because staying up late makes the liver unable to rest, the function of detoxification and detoxification decreases, the blood pressure circulation is not smooth or the detoxification is not good, and only skin detoxification can be used. People who stay up late will be more angry and easily lose their temper.
4. Prone to cancer. If we compare the body to a large electrical appliance, we sleep at night to recharge, and during the day to discharge. According to the theory of traditional Chinese medicine, if we don't sleep at night, we will lose Yang Qi, if we don't rise in the morning, we will kill Yang Qi. There is a biological clock in the human body, which enables people to follow the laws of nature, "work at sunrise, and rest at sunset". Modern medicine also believes that the period from 11 p.m. to 6 a.m. the next day is the 'golden seven hours' of sleep. If you can have a good sleep in this period, then your health will be more guaranteed. On the contrary, if you stay up late continuously, it will lead to the decline of the body's resistance and immunity, then cancer will take advantage of the situation and get cancer.
