1, increasing the risk of breast cancer.

Liu Depei, chief physician of the Department of Obstetrics and Gynecology, Nanjing Hospital of Integrated Traditional Chinese and Western Medicine, Jiangsu Province, said that long-term continuous exposure to artificial light and mental stress will interfere with the secretion of hormones in the human body, thus inhibiting the secretion of melatonin by the pineal gland of the brain and increasing the probability of cancer.

Chinese medicine believes that yang is weak and yin is cold at night. If you stay up late for a long time and don't pay attention to cold protection at night, it will increase the internal cold in the body and lead to breast cancer induced by blood deficiency.

2, increase the risk of gastric cancer.

Chen Yuqian, chief physician of the Department of Gastroenterology, said that the human gastrointestinal tract also needs rest to maintain itself. Staying up late will greatly reduce the effect of gastrointestinal rest, affect the ability of gastrointestinal repair and protection, and weaken gastrointestinal function.

In the long run, gastritis, gastric ulcer, gastric cancer and other diseases will follow. In addition, some people are used to eating late at night, which will increase the burden on the stomach and lead to stomach problems.

3, easy to be sad

Xing, deputy chief physician of the Department of Cardiology, said that sleep is closely related to arrhythmia, sick sinus syndrome, angina pectoris, heart failure and cardiogenic asthma.

During 4:00-7:00 in the morning, the excitability of human sympathetic nerve increases and cardiovascular activity is unstable. If you don't rest at this time, it is more likely to lead to myocardial ischemia, hypoxia, sudden angina pectoris and myocardial infarction.

4, reduce immunity

Xia, deputy director of the insomnia clinic of the Department of Preventive Medicine, said that Chinese medicine believes that "blood will return to the liver as soon as people lie down", and the best stage for the liver to play its role in storing blood and detoxifying is at night 1 1 until 3 am. This period of time can not guarantee to rest on time, which will damage liver qi and reduce resistance and immunity over time. Therefore, people who maintain health and nourish the liver must sleep before 1 1 at night, which is conducive to blood returning to the liver to detoxify.

5, easy to have nightmares

Li Fang, chief physician of respiratory medicine, said that nightmares usually come from the stress of life, and sometimes they may be a signal of health problems.

If you have more and more nightmares, the content of dreams is often that you can't breathe. It is best to find a professional to check whether you have sleep apnea, which is a chronic disease, and your breathing stops or becomes shallow during sleep. Sleep apnea will destroy your sleep because of lack of oxygen.

6, easy to get fat

Zang Ping, the attending physician of the slimming clinic, said that people who sleep less than 6.5 hours a day are more likely to be obese. Lack of sleep will make the human body secrete more "hunger hormones", which will make people overeat and lead to obesity.

Human adrenocortical hormone and growth hormone are secreted at night. Often staying up late can also lead to endocrine disorders, thus forming endocrine disorders and obesity.

7, prone to depression

Experts point out that watching computer or TV for a long time will make people tired, listless and lose appetite. More importantly, the quality of sleep has turned red, making them unable to sleep during the day and night.

After that, the body's long-term fatigue and discomfort are mixed with some emotions of work and life pressure. Once insomnia occurs, it will fall into fear of life and exaggerate the pain in the details of life, leading to long-term depression.

8. It's bad for the brain

According to experts, staying up late often leads to memory loss, slow response, headache and insomnia. This is because staying up late leads to "overtime" of brain nerves, and the result of nerve failure is negative "slack", which causes chronic damage to brain nerves.
