1. Get up and fold the quilt itself-it's also a pollution source. In a night's sleep, human skin will emit a lot of water vapor, making the quilt moist to varying degrees. There are 145 chemicals excreted by human breath and pores distributed all over the body, and 15 1 chemicals evaporated by sweat. The quilt absorbs or absorbs moisture and gas. If you don't let it out, it will overlap immediately, which will easily make the quilt damp and polluted by chemicals. People who don't eat breakfast will feel tired and dizzy if they eat irregularly. Over time, it will cause malnutrition, anemia, decreased resistance, pancreas and gallstones. 3. Loosening the belt after meals can reduce the intra-abdominal pressure, increase the activity of digestive organs and the load of ligaments, thus promoting the aggravation of intestinal peristalsis, prone to intestinal volvulus, abdominal distension, abdominal pain, vomiting and gastroptosis. Sleeping after a meal will make the blood in the brain flow to the stomach. Because blood pressure decreases, the oxygen supply to the brain will also decrease, leading to extreme fatigue after meals, which is easy to cause heartburn, indigestion and obesity. If the blood supply is insufficient, you will fall asleep after meals. This motionless state can easily lead to a stroke. 5. Eating too much can easily lead to memory loss, slow thinking, inattention and weakened stress ability. Often over-satiated, especially over-satiated dinner, due to excessive intake of calories, will make the body fat excess, blood lipids increase, leading to cerebral atherosclerosis. It will also cause a substance called "fibroblast growth factor" to grow tens of thousands of times in the brain, which is a protein that promotes arteriosclerosis. The result of cerebral arteriosclerosis will lead to hypoxia and lack of nutrition in the brain, thus affecting the metabolism of brain cells. Often full, it can also induce gallstones, cholecystitis, diabetes and other diseases, which will make people aging before they get old and shorten their life span. 6. More and more evidences show that the longer the hobby of eating sugar on an empty stomach, the more serious the damage to protein absorption. Because protein is the foundation of life activities, eating sugar on an empty stomach for a long time will affect all kinds of normal functions of the human body, making the human body weak and shortening its life span. 7. Eating salty food sodium stays in the human body, which is easy to form or aggravate high blood pressure and heart disease. 8. Beards have the ability to absorb harmful substances. When people inhale, harmful substances adsorbed on their beards may be inhaled into the respiratory tract. According to the quantitative analysis of the air composition inhaled by bearded people, it is found that the inhaled air contains dozens of harmful substances, including carcinogens such as phenol, toluene, acetone and isoprene, and the air pollution index inhaled by bearded people is 4.2 times that of ordinary air. If you have a beard on your chin and a moustache, the pollution index can be as high as 7.2 times. Coupled with smoking and other factors, the pollution index will be as high as 50 times that of ordinary air. 9. Crossing your legs and crossing your legs will make the blood flow in your legs poor and affect your health. If you are a patient with venous tumor, arthritis, neuralgia and venous thrombosis, crossing your legs will make your condition worse. Especially people with long legs or pregnant women, it is easy to get venous thrombosis. 10. Squinting, rubbing your eyes and squinting, crow's feet are easy to appear in the corner of your eyes. Habitual squinting can also cause eye muscle fatigue, dizziness and headache. When rubbing your eyes, germs can infect your eyes from your hands, leading to inflammation, broken eyelashes or falling off. 1 1. Forced urination may cause acute cystitis, characterized by frequent urination, dysuria, small abdominal distension and pain. A research report released by American scientists pointed out that people who have the habit of holding their urine are five times more likely to develop bladder cancer than the average person. When holding urine, the urine stored in the bladder cannot be discharged in time, resulting in artificial urinary retention. If you hold your urine regularly, your sphincter and detrusor will always be in a state of tension; If you hold your urine for too long, the amount of urine in your bladder will continue to increase, and the internal pressure will gradually increase. After a long time, symptoms of bladder neck obstruction will appear, leading to dysuria and obstruction, or urinary leakage and incontinence. Urinary retention is also easy to cause complicated infection and stones, and will also affect renal function in severe cases. 12. Take a nap at your desk. Most people will have temporary blurred vision after taking a nap at your desk. The reason is that the eyeball is compressed, causing corneal deformation and curvature change. If you press your eyeball every day, the intraocular pressure will be too high, and if this continues, your vision will be damaged. 13. Lying prone makes the spine bend, which increases the pressure on muscles and ligaments, making people still unable to rest while sleeping. In addition, it will increase the pressure on the chest, heart, lungs and face, leading to facial edema and bloodshot eyes after waking up. 14. If you don't wash your face before going to bed, the cosmetics left on your face will cause inflammation such as acne and pinholes, and it will also make your eyes inflamed and cause skin allergic reactions. 15.

This is because the bacteria and residues left in the mouth and teeth have a strong corrosive effect on teeth and tooth age at night. 16. Sleeping late will inhibit the cerebral cortex for a long time, which will cause a certain degree of artificial brain dysfunction, lead to a decline in understanding and memory, and also reduce immune function, disrupt the biological rhythm of the body, make people lazy and inert, and at the same time, it is not good for muscles, joints and urinary system. In addition, poor blood circulation and untimely systemic nutrition delivery will also affect metabolism. Because the doors and windows are closed at night to sleep, the indoor air is cloudy in the morning, and falling in love with the bed is easy to cause respiratory diseases such as colds and coughs. 17. The hot water bath time is too long. Chloroform and trichloroethylene are easily volatile harmful substances in tap water. Because there are more opportunities for water droplets to contact the air during ice bath, these two harmful substances are released a lot. According to the collected data, only 25% chloroform and 40% trichloroethylene are released into the air if hot water bath is used. Bathing with hot water will release 50% chloroform and 80% trichloroethylene into the air. 18. Gambling is harmful to one's physical and mental health, because gambling itself is a strong stimulus. Long-term gambling will make the central nervous system in a state of high tension for a long time, which will easily lead to increased hormone secretion, vasoconstriction, increased blood pressure, and accelerated heartbeat and breathing. , and will increase the incidence of cardiovascular diseases, as well as peptic ulcer and tension headache. 19. Some young and middle-aged people who are engaged in mental work and business are overloaded with life machines all day. Because of their strong competitive psychology, they are under great pressure both physically and psychologically. After excessive mental and physical labor, the ability of anti-fatigue and disease prevention is weakened, which may lead to many diseases.
