What are the behaviors that endanger health? Talk about how to develop good behavior habits and promote health.

First, wash your hands before and after meals: the hand is the "diplomatic organ" of the human body and plays a leading role in everyone's "foreign affairs activities". You need to use your hands to complete the investigation made by scientists. An unwashed hand contains at least 40,000 to 400,000 bacteria. Nail seam is a good place for bacteria to hide. One nail seam can hide as many as 3.8 billion bacteria. The flu virus can survive for 7 days on wet and warm hands. So, my hands are dirty. Moreover, when traveling, visiting and studying, and performing tasks, hands often touch some items and get dirty. Especially patients with infectious diseases and those who seem to be in good health, often spread pathogenic microorganisms to various articles and appliances. As soon as a healthy person's hand touches it, pathogenic microorganisms will come to your hand. Washing hands can remove bacteria and eggs attached to hands. Washing your hands with tap water can wash 80% of the bacteria off your hands. If you wash with soap first and then tap water, you can wash 99% of the bacteria off your hands. Second, don't vomit: everyone will vomit, but not everyone has a good way to vomit. Some so-called "health lovers" spit sputum on the ground and wipe it clean with shoes, thinking that it will be clean if you can't see sputum. I didn't know that sputum contained millions of bacteria, viruses and fungi. People with respiratory diseases, such as tuberculosis, influenza and meningitis, have more bacteria and viruses in their sputum, which is the case with SARS. Millions of mycobacterium tuberculosis can be found in one mouthful sputum of tuberculosis patients. If you spit on the ground and the sputum is dry, bacteria will fly into the air with the dust, and healthy people may get respiratory diseases by inhaling such dust. So we should form a good habit of not spitting. Sputum should be spit in the spittoon, which should be scrubbed regularly every day. Where there is no spittoon, the spittoon should be wrapped in waste paper and thrown into the wastebasket or dustbin to avoid spitting and maintain the hygiene of public places. 3. Don't cough or sneeze at others: If you don't pay attention to the occasion, sneezing in front of others or food is an unhealthy bad behavior. According to the survey, a cough can eject 20,000 tiny droplets, and a sneeze can eject nearly 654.38+0 billion droplets. Moreover, the speed of droplet ejection is very fast, and it can fly 4.6 meters in less than 1 s, and it can fly 9 meters with the wind. The nasal cavity and throat are one of the places with the densest bacteria and viruses, and the sprayed droplets contain a lot of bacteria and viruses. A sneeze can spit out 85 million bacteria. These tiny water droplets can float in the air for a long time, 30-60 minutes in a windless room, and up to 30 hours. Among the legal infectious diseases in China, 15 is airborne (such as chicken pox, mumps, mycoplasma pneumonia, etc. Therefore, for everyone's health, we should pay attention to politeness and hygiene when coughing and sneezing. 4. No smoking: Smoking is harmful and useless, which is recognized by the scientific community all over the world. Tobacco smoke contains more than 3000 kinds of harmful substances. Among them, there are mainly nicotine (nicotine), cigarette tar, light hydrofluoric acid, acrylic acid, carbon monoxide and so on. Nicotine is a toxic substance. Tobacco tar contains nitrosamines, phenols, arsenic, radioisotopes and other carcinogenic or carcinogenic substances, especially benzopyrene, which is recognized as a strong carcinogen. According to statistics, the incidence of lung cancer in people who smoke 40 cigarettes a day is 70 times higher than that in non-smokers. In addition, smoking is closely related to laryngeal cancer, esophageal cancer and gastric cancer. Smoking can promote the development of systemic arteriosclerosis and hypertension, so the incidence and mortality of cardiovascular and cerebrovascular diseases of smokers are higher than those of non-smokers. In addition, smokers are prone to bronchitis, bronchitis and emphysema. Some people say that smoking can refresh oneself and improve work efficiency, which is a misunderstanding. Modern medical research believes that, therefore, people who smoke heavily for a long time lose their balance in the process of excitation and inhibition of cerebral cortex, but instead show decreased memory, distraction and work efficiency. The incubation period of many smoking-related diseases is very long, and it is not as fast as eating highly toxic substances. So in a short time, people often can't see his harm. Sometimes it takes decades from smoking to death. This is also the main reason why people don't know enough about the harm of smoking. There are about 200-300 million smokers in China, accounting for more than15 of the national population and10-0/0.2 billion smokers in the world. Not only will it consume a lot of money every year, but many years later, the state and individuals will invest unimaginable money to treat various diseases caused by smoking. At present, European and American countries have seen the great harm of smoking and used legal, economic and political means to greatly reduce the smoking rate of the masses. For example, American law clearly stipulates that selling cigarettes to teenagers under the age of 18 will be severely punished and even prosecuted to the court. Newspapers also published complaints from local people in Europe and the United States about the harm that tobacco companies and advertising agencies have done to themselves and their families. At present, China is still in the process of reform and opening up, and some laws are not perfect. Some departments also use cigarettes as a magic weapon to create huge profits. Young people regard a cigarette in their hand or mouth as a sign of maturity, and even some women have joined the ranks of smokers now. A famous foreign scholar predicts that about 50 million young people under the age of 20 will die of smoking in China in the future. So at present, many people think that smoking is a public hazard, a plague in 2 1 century, and opium in the new century, which harms the Chinese nation. 5. Don't drink too much: Modern medical research shows that when the alcohol concentration reaches 0.6%, it often leads to death. The harm of drunkenness is systemic and the consequences are quite serious. A Chinese scholar dissected 47 corpses that died of drunkenness and found that all the corpses had extensive internal congestion, especially congestion, edema and bleeding of gastric and duodenal mucosa, and some gastrointestinal mucosa could be necrotic. Many scholars have pointed out that heavy drinking will lead to a high degree of cerebral cortex inhibition, inhibition of respiratory and circulatory centers, leading to respiratory arrest, which is a common cause of death for drunkards. Do not drink unclean water, eat raw fruits and vegetables should be washed or peeled, do not urinate anywhere, do not litter.
