Health hazards of holding back fart: A lot of gases, such as nitrogen, hydrogen sulfide and dioxins, will be produced in the process of intestinal metabolism.
Carbon, ammonia, indole, etc. The mixture of these gases is fart. Therefore, the above gases contained in fart are harmful substances. If you hold your fart, these gases will be reabsorbed by the intestinal mucosa, enter the blood and tissues, and further harm the body. Therefore, when there is fart, you must not hold it back. If you have the habit of holding back your fart frequently, it will easily lead to chronic poisoning, and symptoms and signs such as listlessness, indigestion, dizziness and sallow complexion will appear.
The health hazard of inertia? Inertia refers to a negative psychological expression of laziness, depression and lack of progress. To put it simply, I just don't want to use my head and don't want to do it. Medical psychology believes that inertia has the following hazards to physical and mental health:
1. Slow thinking: The human brain also follows the law of use and abandonment. People who use their brains frequently can increase the release of special biochemical substances such as enkephalin, and the content of ribonucleic acid in the brain is higher than the average level of ordinary people 10% ~ 20%. RNA can promote the pituitary gland to secrete neurohormone, a new protein molecule, a "memory molecule" composed of polypeptide. It plays an important role in promoting the development of memory and intelligence. Because the brain function of lazy people is not fully exerted, the release and level of bioactive substances such as enkephalin and ribonucleic acid are reduced. After a long time, brain function will gradually deteriorate, thinking will gradually slow down, and the ability of analysis and judgment will also decline.
2. Decline in physical fitness: Lazy people have little limb activity. In the long run, the body will not get exercise, physical consumption will be reduced, and the "income" of heat energy will be greater than "expenditure", and the body will gradually gain weight and even suffer from various diseases. With less physical activity, the functions of various organs and systems of the body will be "adaptive". In addition, the immune function of the body also changes according to the law of using it and discarding it. Therefore, laziness will inevitably reduce the physical quality.
3. Harm to interpersonal relationships: lazy people are willing to be mediocre and do not strive for progress, which will naturally cause dissatisfaction among people around them, resulting in negative emotions, such as depression, frustration, resentment, irritability, resentment, etc. The expression of this emotion. It will aggravate interpersonal conflicts, worsen relationships and even affect normal work and life.
4. Lead to premature aging: Research shows that the health of middle-aged and elderly people depends on psychological balance. It depends on the nervous system to maintain a certain tension. Inertia will reduce the body's adaptability to the external environment and lead to premature aging. Some data show that the risk of cardiovascular disease is 3.5 times higher than that of ordinary people, and the heart declines prematurely.
5. Susceptibility to psychosomatic diseases: Negative emotions caused by inertia can cause a series of malignant physiological and biochemical changes in the body, affect endocrine function, and make the body suffer from psychosomatic diseases, such as palpitation, duodenal ulcer, coronary heart disease and hypertension. This is a large-scale syndrome. The emergence of psychosomatic diseases will aggravate neuropsychology and play a role in fueling the development of psychosomatic diseases. American scientist Franklin said, "inertia, like rust, consumes the body more than labor." In order to be healthy, we need to give up inertia. Inertia is harmful and should be given up.
The Harm of Snacks to Health Ten Bad Snacks
1. Jelly eating jelly can not only supplement nutrition, but even hinder the absorption of some nutrients. At present, the jelly-based three ingredients sold in the market are carrageenan, a carbohydrate that the human body can't absorb, and basically contains no juice. Its sweetness comes from refined sugar and its fragrance comes from artificial essence.
But there is no fat in jelly, and some "water-soluble dietary fibers" contain fat. Eating a small amount won't hurt you or make you fat, but you can't expect to use it to "increase nutrition".
2. Potato chips have low nutritional value and contain a lot of fat and energy. Eating too much will destroy appetite and easily lead to obesity, which is also the enemy of panel bodybuilding.
3. The nutritional value of popcorn is acceptable, but it contains a lot of lead, which will affect children's intellectual and physical development and damage the neurological function of adults.
4. Fruit candy and lollipop only contain sugar, which has nothing to do with fruit. Its fruity taste comes from additives such as essence and pigment. Eating too much can easily lead to dental caries and obesity.
5. Preserved fruits and preserves During the processing of these foods, the vitamin C contained in fruits is basically completely destroyed, and there is almost no other nutrition except a lot of heat energy. Eating so much polysaccharide can also lead to the lack of vitamin B and some trace elements. In addition, some preserved fruits and other foods may also contain preservatives, which will affect health if eaten frequently.
6. The salt content of dark plum and plum is too high. If you consume a lot of salt for a long time, it will induce hypertension.
7. Fast food noodles have high fat content and low nutritional value, so eating more is not conducive to a balanced diet.
8. Cookies are high-fat, high-energy foods with less vitamins and minerals. Eating too much is not conducive to a balanced diet and can easily lead to obesity.
9. The nutritional value of bubble gum and chewing gum is almost zero. Some products contain a lot of preservatives and artificial sweeteners, especially some inferior products, which are very harmful to health.
10. Puffed snacks are rich in nutrition, but they contain a lot of food additives such as pigments, flavors, preservatives, artificial sweeteners, accessories, etc. It is unhealthy to eat too much.

How to prevent indoor formaldehyde from endangering human health? You can add about 5-7 drops of lavender essential oil to tap water, shake it in a watering can and spray it around the room. You can also place chlorophytum indoors, and you can also put charcoal or bamboo charcoal, vinegar and so on.
SY's frequent harm to health is related to your growth and endocrine, because the loss of protein is related to water.
Main sources of indoor radon and its harm to human health. People spend 70% ~ 90% of their life indoors, and the indoor environment is directly related to human health. Indoor radon is the main factor that affects indoor environment, so people should know about it in order to take corresponding measures to reduce the harm of radon to their own health.
1. What is radon?
Radon is ubiquitous in our living environment. Radon is the only natural radioactive inert gas produced by the decay of radium and thorium. It has no color or smell. The decay products of radon in the air are called radon daughters. Radon and its daughters can form radioactive aerosols in the air at room temperature, pollute the air, and are easily intercepted by the respiratory system and accumulate continuously in the region.
2. How harmful is radon to human body?
According to the National Security Council, as many as 30,000 people in the United States die from radon every year. As early as 1980s, the US Department of Health announced that radon was the second leading cause of lung cancer. There is also a serious radon pollution problem in China. Some survey results show that indoor radon concentration is much higher than outdoor radon concentration, which is several times of outdoor radon concentration, and some indoor radon content is six times as high as the national standard! According to incomplete statistics, there are more than 50,000 cases of lung cancer caused by radon in China every year. Therefore, radon has been listed as an important indoor carcinogen by international cancer research institutions, ranking first among the three human carcinogens confirmed by the World Health Organization, which must attract our attention. After 9 years' investigation, the research team led by researcher Wang Zuoyuan from the Institute of Radiation Protection and Nuclear Safety Medicine of China Center for Disease Control and Prevention got the risk index of lung cancer caused by indoor radon pollution for the first time: 0. 19. It means that when the radon concentration in indoor air increases 100 baker/m3, the probability of people living in this environment will increase 19%.
3. How did indoor radon come from?
Indoor radon mainly comes from the following sources:
1. Radon is separated from the foundation soil. High concentrations of radon can be found in soil and rocks containing uranium, radium and thorium deep in the stratum. These radon can pass through the stratum fault zone and enter the soil and atmosphere. When a building is built on it, radon will spread indoors along the cracks in the ground.
2. Radon separated from building materials. 1982 The report of the United Nations Scientific Committee on the Effects of Atomic Radiation points out that building materials are the main source of indoor radon. Such as granite, brick sand, cement and gypsum, especially natural stones containing radioactive elements, are easy to release radon.
There is also radon entering the room from outdoor air, and radon released from water supply and natural gas used for heating and kitchen equipment.
4. How can we reduce indoor radon concentration?
No matter how high or low indoor radon content is, it will do harm to human body, but as long as we pay attention to reducing indoor radon content, this harm can be reduced. From some experiences at home and abroad, there are many ways to reduce indoor radon level.
1. Selection of building foundation. When selecting the foundation before building, if possible, please ask the relevant departments to do radon detection first, and then take radon reduction measures. Individuals should consider this factor when buying a house.
2. Selection of building materials. When building construction and room decoration, try to choose low-level radioactive building and decoration materials that meet national standards. Real estate developers should pay special attention to the radioactivity of building materials and entrust radiation protection safety institutions to carry out testing in time. Residents should pay more attention to this when decorating their homes.
3. In the interior decoration of office buildings and families, attention should be paid to caulking all cracks on the ground and walls, especially in the basement and the first floor and rooms with high indoor radon content, which can effectively reduce radon precipitation.
4. Good indoor ventilation is an effective way to reduce indoor radon concentration. According to experts' experiments, if a room with radon concentration of 1, 5 1 baker/cubic meter is ventilated 1 hour, the indoor radon concentration will be reduced to 48 baker/cubic meter. Conditional can be equipped with effective indoor air purifier.
5. What should I do if I suspect the existence of radon in my working and living space?
If you are concerned about whether there is radon in your work and living space and whether it is necessary to take measures to reduce radon, you can consult the Radiation Protection Safety Institute of Shandong Provincial Center for Disease Control and Prevention, or you can apply for radiation detection service in the indoor radiation detection room.
