A man who stayed up until 3 a.m. every night was diagnosed with stomach cancer! Staying up late is more terrible than you think

Yesterday, a news story about a man who stayed up until 3 o'clock every night and was diagnosed with stomach cancer became a hot topic. Staying up late may be more terrifying than you think.

Staying up late is more terrible than you think

Staying up late increases the risk of stomach cancer

A study by the University of Hong Kong found that when rats were deprived of sleep for seven days, the blood flow to the stomach decreased by 15%, and the gastric mucosa was damaged by 30% to 50%. This means that lack of sleep can easily lead to damage to the gastric mucosa, making it easy to suffer from peptic ulcer disease.

Chen Yuqian, chief physician of the Department of Gastroenterology, said that the human gastrointestinal tract also needs rest to achieve self-"maintenance". Staying up late will greatly reduce the effect of rest for the gastrointestinal tract, affect the stomach's ability to repair and protect, and weaken gastrointestinal function. In the long run, diseases such as gastritis, gastric ulcers, and gastric cancer will follow. In addition, some people are used to eating when they stay up late, which will increase the burden on the gastrointestinal tract and cause stomach problems.

Staying up late can easily induce diabetes

Shi Fengying, chief physician of the Endocrinology Department of Zhongshan Hospital Affiliated to Fudan University: For people with a family history of diabetes, staying up late often increases the risk of diabetes. This is because compared with other people, people with a family history of diabetes have certain predisposing factors for the disease. If the conditions are right, just like a seed encountering a suitable environment, it will quickly take root and sprout.

Staying up late can easily lead to high blood pressure and even sudden death

Ding Jiandong, chief physician of the Department of Cardiology at Zhongda Hospital Affiliated to Southeast University: Studies have shown that long-term lack of sleep is an important pathogenic factor of hypertension. This also greatly increases the risk of people who stay up late suffering from various sudden cardiovascular and cerebrovascular diseases, and in severe cases can lead to sudden death.

Staying up late can increase risk of 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 rate of people who often stay up late is more than 3 times higher than that of the general population. This is because cancer cells are produced during cell division, and cell division mostly occurs during sleep. Staying up late will affect the normal division of cells, thus causing cell mutations and the production of cancer cells.

Staying up late often leads to depression

Researchers from Thailand's Mahidol University found that type 2 diabetics who like to stay up late are more likely to be depressed than type 2 diabetics who go to bed early and get up early.

The researchers selected nearly 500 type 2 diabetics from the United States and Thailand, 70% of whom were women. All participants reported their depressive symptoms, sleep quality, and preferred activities and sleep time on a questionnaire. The analysis results showed that in both groups of subjects, patients who preferred nighttime activities had more depressive symptoms than those who preferred daytime activities. After the researchers adjusted for other factors that may affect the occurrence of depression (such as sleep quality, age, and gender), the above conclusions still held true.

The research results, which were announced at the annual meeting of the American Endocrine Society, show that developing the habit of going to bed early and getting up early is more beneficial to the physical and mental health of diabetics.

Staying up late hurts your eyes

The damage to the eyes caused by staying up late is not as simple as the appearance of "panda eyes". Long-term overload of eyes can cause pain, dryness and other problems in the eyes, and even cause people to suffer from dry eyes.

In addition, eye muscle fatigue can also lead to temporary vision loss. Excessive fatigue caused by staying up late for a long time may also induce central retinitis, leading to a sudden drop in vision.

Staying up late causes neurasthenia, headache and insomnia

The sympathetic nerves of a person should rest at night and be excited during the day, so that they can support a day's work. However, the sympathetic nerves of people who stay up late are excited at night. The next day after staying up late, the sympathetic nerves are difficult to be fully excited, which will make people lack energy, feel dizzy, have memory loss, lack of concentration, slow reaction, forgetfulness, dizziness, headache, etc. Over time, more serious problems such as neurasthenia and insomnia will occur.

Staying up late increases breast cancer risk

A Canadian medical study found that women who work night shifts for a long time have a doubled risk of breast cancer. Previously, researchers from Queen's University in Canada compared the health data of 1,134 female breast cancer patients with 1,179 healthy women. The results showed that compared with other women, women who work night shifts for more than 30 years have a two-fold increased risk of breast cancer, which shows that staying up late has a direct impact on breast cancer.

Liu Depei, chief physician of the Department of Obstetrics and Gynecology at the Nanjing Hospital of Integrated Traditional Chinese and Western Medicine in Jiangsu Province, said that staying up late for a long time and being exposed to artificial light, coupled with mental tension, will interfere with the secretion of hormones in the human body, thereby inhibiting the pineal gland in the brain from secreting melatonin and increasing the probability of cancer.

Staying up late can make you sad

Experts from the Population Health Department of the U.S. Centers for Disease Control and Prevention conducted a new study, selecting approximately 54,000 adults aged 45 and above. The results showed that compared with people who sleep 7 to 9 hours a day, people who sleep too little have a higher risk of developing coronary heart disease, stroke and other diseases.

Xing Junwu, deputy chief physician of the Department of Cardiology, said that sleep is closely related to arrhythmia, sick sinus syndrome, angina pectoris, heart failure, and cardiac asthma. During the period from 4 to 7 a.m., the excitability of the sympathetic nerves of the human body increases, and cardiovascular activity is unstable. If you are not in a resting state at this time, it is more likely to cause myocardial ischemia and hypoxia, leading to sudden angina pectoris, myocardial infarction, etc.

Staying up late reduces immunity

A new study in the United States found that the rhythm of human physiological reactions is consistent with the alternation of day and night. Once this rhythm is disrupted, the disease resistance of the human immune system will be reduced. Researcher Yu Xiaofei, a doctor of immunology at the University of Texas Southwestern Medical Center, said: "This research result not only reveals how the alternation of day and night affects the body's immune system at the molecular level, but also helps us to more effectively use our own immune function to fight infection or prevent immune diseases."

Staying up late can cause nightmares

According to a new study published in the journal Sleep and Biological Rhythms, going to bed too late is more likely to cause nightmares. In the study, Turkish scientists investigated the sleep habits of 264 college students and measured the frequency of their nightmares using the Dream Anxiety Index. The results showed that the average Dream Anxiety Index of participants who were used to staying up late was 2.10, while that of participants who were used to going to bed early was only 1.23. In addition, the researchers conducted an online survey of nearly 4,000 people and found that among women in their 20s, staying up late was positively correlated with nightmares.

Staying up late can make you fat

A research report published in the American magazine Sleep stated that the later people stay up late, the more calories they consume and the more likely they are to gain weight. The study involved 255 volunteers, some of whom were in the group that stayed up late and lacked sleep, and some of whom were in the control group. The results showed that when the volunteers in the group that stayed up late and lacked sleep went to bed at 4 a.m. and got up at 8 a.m. four hours later, they consumed an average of about 550 calories after 11 p.m., which far exceeded the body's needs, leading to obesity.

Zang Ping, the attending physician of the weight loss clinic, said that people who sleep less than 6.5 hours a day are more likely to get obesity. Lack of sleep can make the human body secrete more "hunger hormones", which can cause people to overeat and lead to obesity. The human body's adrenal cortex hormones and growth hormones are secreted only during sleep at night. Staying up late often can also lead to endocrine disorders, thus forming endocrine disorder obesity.

Staying up late is harmful to the brain

A study by Uppsala University in Sweden found that the brain chemicals neuron-specific enolase (NSE) and S-100B protein in subjects who did not sleep all night showed an upward trend, both of which are markers of brain damage. The experimental results show that having a good sleep is essential for maintaining brain health.

Experts say that staying up late often can cause people to suffer from memory loss, slow reaction, headaches, insomnia, etc. This is because staying up late causes the brain nerves to "work overtime", and the result of nervous fatigue is passive "slacking", causing chronic damage to the brain nerves.
