The cause of disease
Supercooling stimulation
People's skin temperature is different, that is, the temperature of limbs is lower than that of trunk, the temperature of hands and feet is lower, and the ability of human body to adjust temperature is powerless.
anion
In an air-conditioned clean room, negative ions are almost equal to zero. Air negative ions are negatively charged air particles, which can cheer people up and improve human functions. They are called air "vitamins", and the lack of negative ions can make people feel headache.
The air is not fresh.
People feel chest tightness, palpitation, dizziness and fatigue, and their work efficiency and health status are obviously reduced. According to the measurement, the number of negative ions per square centimeter in an ordinary room is fifty, but it can be reduced to less than ten after using air conditioning devices.
Sudden temperature change
When you enter an air-conditioned room from a high-temperature outdoor or other house, the temperature difference is large, the temperature changes suddenly, and the autonomic nervous system of the human body is difficult to adapt, so the symptoms of air-conditioning disease will appear. Manifested as irritability, nervousness, insomnia, etc. In addition, because the air-conditioned room is usually closed, although the air-conditioning system can filter out most of the dust and bacteria in the air, the residual bacteria in the air will still cause pollution. People live in a monotonous air-conditioned environment for a long time, and the biological rhythm of the human body is destroyed, which will also cause autonomic nerve dysfunction. [ 1]
symptom
cardinal symptom
The main symptoms of air conditioning disease are different because of different adaptability. The general symptoms are chills and discomfort, fatigue and weakness, pain in muscles and joints of limbs, headache and low back pain, and severe cases can also cause facial paralysis. The reason is that the vascular nerve function of the local tissue in the ear is disordered, which makes the arteriole located in stylomastoid foramen spasm, causing primary facial nerve ischemia, and then venous congestion and edema, which oppresses the facial nerve and makes the affected side skew.
disadvantaged groups
Generally speaking, people who are prone to air conditioning diseases are mainly the elderly, children and women. Old people and children have low body resistance, while women have thin clothes and bare arms.
Susceptible site
The most fragile respiratory tract is the most fragile. Once air conditioning breaks through the fragile "defense line" of respiratory tract, cold symptoms such as cough, sneezing and runny nose are mild, that is, upper respiratory tract diseases, and air conditioning causes more serious lower respiratory tract diseases, especially pneumonia. Especially when working and studying under central air conditioning, central air conditioning is very suitable for the spread of Legionella, and the incubation period is about 2- 12 days. Although the upper respiratory tract is unresponsive, it causes fever, chills, muscle aches, dry cough, no phlegm or less phlegm. If not treated in time, you will continue to have a fever, dry cough, chills, and even die of respiratory failure. In addition, although the room is cold, the humidity is too low, which is not good for people's eyes and nasal mucosa. A dry environment is suitable for the survival of bacteria and viruses. People should be especially careful when their noses and throats are dry. At the same time, the dust and dust mites at home cannot circulate, and people with allergies are prone to allergic reactions. Brain nerves will be out of balance, and people who often sit in air-conditioned rooms will often say "I am dizzy, see stars, and forget things" and so on. According to reports, this is a common brain imbalance reaction caused by air conditioning disease. Air conditioning not only causes colds, but also does great harm to the brain. The negative ions contained in the air can inhibit the central nervous system and relieve brain fatigue. But the air conditioner absorbs too many anions, which makes more and more cations in the room. The imbalance of anion and cation also makes the human brain nervous system unbalanced. If indoor air conditioning only makes you dizzy and sick, then indoor air conditioning adds a little danger to the driver's brain and nerves. Many drivers who are used to turning on air conditioners sometimes feel tired, headache and numbness in their hands and feet. It is easy to get sleepy in summer, lose control of the brain and feel uncomfortable all over, which is easy to cause traffic accidents. Young people who are prone to colds in joints and intestines often don't pay much attention to joint pain caused by air conditioning, but such problems will occur when air conditioning is turned on for a long time. In summer, the outdoor air is hot, and people generally wear less. But the indoor air conditioner blows badly and the clothes are so thin. Such a low-temperature environment will stimulate the rapid contraction of blood vessels and poor blood circulation, leading to joint injury and cold pain, such as stiff neck and back, sore waist and limbs, cold and numbness in hands and feet. In addition, too "cold" in the room can easily lead to weakened gastrointestinal movement. In addition, people often eat cold drinks in summer, and both inside and outside the intestine are controlled by "cold". It's not surprising that many people pull and vomit. In fact, this kind of autonomic nervous disorder caused by sympathetic nerve excitation is most likely to occur in young women, mainly manifested as menstrual disorder. Nowadays, many white-collar women work in the company office, under low temperature air conditioning all day and wearing short skirts at the same time. Originally, their physique was relatively weak, and their hands and feet dissipated heat quickly, leading to vasomotor disorders. Such cold stimulation is likely to affect ovarian function, causing ovulation disorder, menstrual disorder or severe abdominal pain.

preventive
◆ 1. When using air conditioner, be sure to pay attention to ventilation. Open the window regularly every day, turn off the air conditioner, and add air for ventilation to keep a certain amount of fresh air indoors. It is best to clean the air conditioner once every two weeks. [2] ◆2. When going out in an air-conditioned environment, you should first move in the shade for a while, and then move in the sun after your body adapts; If you are in an air-conditioned room for a long time, you should go outdoors more and drink more boiled water to speed up your metabolism. ◆3. The room temperature and outdoor natural temperature of the air conditioner should not be too high, and should not exceed 5 degrees. It is best not to use air conditioning at night. It is safer to turn off the air conditioner when you are asleep. Being outdoors before going to bed is conducive to promoting blood circulation and preventing air-conditioning diseases. ◆4. When working and studying in an air-conditioned environment, don't let the cold air from the air outlet blow directly on your body. It is best not to blow air conditioning directly when sweating, so the temperature drops too fast and it is easy to get sick. ◆5. Smoking is prohibited indoors. ◆6. Always keep your skin clean and hygienic. This is due to frequent contact with air-conditioned environment, sudden changes in heat and cold, and bacteria attached to the skin are easily blocked in sweat glands or sebaceous glands, causing infection and suppuration. Therefore, always take a bath and keep your skin clean. ◆7. Use disinfectants to kill and prevent the growth of microorganisms. ◆8. Add a dehumidifier to prevent bacterial growth. ◆9. Don't turn on the air conditioner in the stationary car, so as to prevent the carbon monoxide discharged from the automobile engine from flowing back into the car and causing an accident, that is, carbon monoxide poisoning. ◆ 10. Pay attention to the clothes in the workplace to meet the requirements of keeping warm in an air-conditioned environment. ◆11Turn on the air conditioner above 26 degrees Celsius, which saves energy and is not easy to get sick. The prevention of air-conditioning diseases is mainly the above ten items. If you have symptoms such as cold, fever, pneumonia, mouth and eyes askew, you should consult a doctor in time.
New preventive technology
At present, the world's leading high-purity air negative ion technology is an "ion converter" technology invented by Japanese scientist Moriguchi, MD, who is known as the "first person in negative ions". It is a patented technology that uses the natural resources of the earth to generate natural air negative ions. It is understood that since the beginning of this year, products and technologies related to this important invention have been introduced to China through the internationally renowned brand Sailumei founded by Dr. Horikou. The air negative ions produced by it are no different from those produced in nature, which is very suitable for regulating human body functions and plays an important role in improving physical fitness and maintaining health. ◆ The introduction of this technology will bring China customers the most advanced environmental improvement equipment in the world, and will be able to meet the needs and tastes of the most critical building owners, families and car owners in China. With the release of Sailumei series products, the definitions of environmental improvement equipment and negative ion devices of top central air conditioners for home and vehicle are updated again. In summer, when the temperature is high and the clothes are thin, staying in a low temperature environment for a long time transmits the feeling of' cold' to the thermoregulation center, instructing the skin blood vessels to contract and the sweat glands to stop secreting, so as to reduce heat dissipation and maintain body temperature; The feeling of' cold' excites sympathetic nerves, which leads to the contraction of blood vessels in abdominal cavity and the weakening of gastrointestinal movement, resulting in many corresponding symptoms. Cold stimulates female body, which can affect ovarian function and cause ovulation disorder and menstrual disorder. In addition to the above cold factors, doors and windows are closed and there is a lack of fresh air; The temperature difference between inside and outside the air-conditioned room is too large; And although there are air-conditioned filters that can remove most of the dust, they can't remove microorganisms, and pathogenic bacteria can easily board, grow and reproduce in air-conditioned rooms ... these are the causes of diseases.
Preventive diet
In addition to often opening windows for ventilation, Koreans also have a good way to fight air-conditioning diseases with celery porridge. Wash celery, cut into pieces, put cold rice into a pot, add water, add celery after the rice becomes sticky, add sesame oil and appropriate amount of salt after a little cooking. Air-conditioned rooms are cooler, and celery is a cool food. Why can it fight air conditioning disease? Celery, celery and celery have the same composition and function, and are rich in provitamin A, vitamin B 1, B2, vitamin C and vitamin P, as well as trace elements, protein, mannitol and dietary fiber. In a closed air-conditioned room, the internal heat of the human body cannot be discharged, which is easy to cause diseases. Celery has the functions of clearing away heat, promoting gastrointestinal peristalsis and helping to dispel summer heat. When buying celery, you should choose short and thick stems and few green leaves; The freshness of celery mainly depends on whether the leaves are straight. The leaves of fresh celery are straight. Celery stored for a long time, the tip of the leaf will tilt, the leaves will become soft, and even yellow and rust. Why can drinking porridge fight air-conditioning disease? In a closed air-conditioned room, people's body temperature regulation, water and salt metabolism, circulation, digestion, nerves, endocrine and urinary system will all change, and the loss of appetite in summer will also limit the absorption of nutrients. Therefore, it is a good method to supplement nutrition to combat air-conditioned cold rice porridge disease. Drinking porridge can enhance appetite and replenish physical strength; Drinking porridge can replenish water for the body and effectively prevent constipation; It can also prevent colds, prevent dry throat and regulate the stomach. Why do you cook porridge with cold rice? Casserole porridge is the best, but it's a "slow work" thing, but office workers can't spare the time. Cooking porridge with cold rice saves time and is nutritious. What are the benefits of adding sesame oil to porridge? Reminder, remember to add sesame oil after cooking porridge. This fragrance is not only appetizing, but also beneficial to the digestion and absorption of food. Sesame oil is rich in nutrition and vitamin E, which can promote cell division and delay aging. Sesame oil can protect blood vessels. Sesame oil contains about 40% unsaturated fatty acids such as linoleic acid and palmitic acid, which is easily decomposed, absorbed and utilized by human body, promotes cholesterol metabolism and helps to eliminate deposits on arterial wall. Sedentary people are prone to habitual constipation. Drinking a mouthful of sesame oil on an empty stomach in the morning and evening can relax the bowels. Drinking sesame oil before drinking can protect the mouth, esophagus, cardia and gastric mucosa. Drinking sesame oil often can enhance the elasticity of vocal cords, make the glottis open and close flexibly and effectively, and have a good recovery effect on hoarseness and chronic pharyngitis.
[Edit this paragraph] Disease prevention in different environments
driver
According to the research of medical experts, in the hot summer, the temperature inside the air-conditioned car differs greatly from that outside the car, which makes it difficult for some drivers to adapt to this obvious temperature change from cold to hot, and it is easy to cause the body's resistance to air-conditioning diseases to decline when driving, thus leading to the occurrence of colds. So the temperature of the air conditioner should be constant. The best standard of constant temperature is: the temperature difference between inside and outside the car is controlled within 5℃, and the maximum is not more than 7℃. In this temperature range, the body temperature center of the human body can be flexibly and freely adjusted; If the temperature difference exceeds this limit, it will be difficult for the human body to adapt and the body will have discomfort symptoms. In addition, vehicles equipped with air conditioning generally have better sealing performance. When the air conditioner works, the replacement time of the air in the car is 2 to 5 times longer than usual, and some even 8 times. Most people will feel dizzy and tired after staying in this environment for a few hours, and their memory will also decline. If the vehicle is not driving, it is more dangerous to use air conditioning. Because when the air conditioner works, it will input carbon monoxide gas discharged from the engine into the car. In hot summer, when enjoying the coolness brought by air-conditioned cars, we must strengthen self-care and improve our physical resistance. In order to avoid accidents when using automobile air conditioners, the following points should be noted: 1. When the car is parked, try to avoid using the air conditioner for a long time, and generally it is better not to exceed 1 hour; 2. If you need to use the air conditioner for a long time, you should use the external air circulation device and open the window to ensure the fresh air in the car. [3]
office
1. Avoid wearing short skirts and keep some thick clothes around. 2. Avoid air conditioning blowing directly on a certain part of the body for a long time. 3. Take a proper rest and exercise during the break. 4. Avoid cold drinks and try to drink warm water. 5. Exercise at ordinary times to enhance physical fitness. 6. Take a bath in warm water, dispel cold and decompress.
[Edit this paragraph] Disease prevention for different groups of people
young people
Air conditioning+cold air, neck and shoulders are the most injured. "Enjoying the artificial cold air of air conditioners and fans is quite harmful to human health. The prevention of air-conditioning diseases is very heavy, from neck and shoulder pain and arm numbness to dizziness, shoulder pain and arm weakness. " He Yingshan, deputy chief physician of the Upper Limb Orthopaedics Department of Zhengzhou Orthopaedics Hospital, said that repeated cold exposure in air-conditioned rooms for a long time can easily cause damage to neck, shoulders and muscle fibers. "Especially for beauty-loving women who often wear strapless clothes, staying in an air-conditioned room for a long time is easy to induce periarthritis of shoulder, which in turn leads to cervical degeneration." He Yingshan reminded that this disease can be prevented by pricking collaterals and cupping in traditional Chinese medicine, that is, acupuncture stimulates acupoints to relax qi and blood, and then a set of cupping, cupping and cupping methods are used to treat neck and shoulder stiffness. Or prepare a turtleneck dress in an air-conditioned room to protect your neck from cold, and try to avoid using air conditioner and fan at the same time.
the aged
Cold air easily induces old cold legs. "Since the summer, the number of patients with old cold legs in outpatient clinics has also increased." Lu, chief physician of acupuncture department of Zhengzhou Traditional Chinese Medicine Hospital, said that leg cold is common in winter, but with the popularity of air conditioning in recent years, it is not uncommon for the elderly to stay in air-conditioned rooms for a long time to induce leg cold in summer. "In addition to the old cold legs, the outpatient survey also found that 80% of them are due to working, studying and living in a low-temperature room with air conditioning on for too long, and the knee joint is stimulated by cold, leading to diseases such as synovitis, bursitis and knee arthritis." Lu pointed out that the horizontal temperature of the ground is the lowest after the indoor air conditioner is turned on in summer. People's legs are in the low temperature of the ground for a long time, and they have short clothes and many clothes in summer, and their exposed knees are easily stimulated by cold. Lu reminded that in order to prevent the "air-conditioned leg" disease, try not to stay in the air-conditioned room for a long time. If you can't leave the low-temperature space for work reasons, you'd better wear air pants and stockings to protect your knees and soles.
children
Blowing the air conditioner for a long time is easy to get pneumonia. The high temperature makes adults reluctant to go out in air-conditioned rooms. Parents who love their children are worried that their children can't stand the heat, so they choose to let their children wait in the air-conditioned room for a long time. "Children who blow air conditioners for a long time will not only suffer from diseases such as colds and respiratory infections, but also have poor air circulation in air-conditioned rooms due to the large temperature difference between indoor and outdoor, which is more likely to cause pneumonia." Hong Song, deputy chief physician of Pediatrics Department of the Second Affiliated Hospital of Zhengzhou University, explained that children have less subcutaneous fat and abundant capillaries, and the thermoregulatory center has not been fully developed. Adults can feel the temperature difference, but children can feel it. In the cold air environment of air-conditioned room, children's capillaries contract, sweat gland pores are closed, sympathetic nerves are excited, visceral blood vessels contract, gastrointestinal peristalsis is weakened, resistance is weakened, all kinds of bacteria and molds grow and breed in air-conditioned room, and the air is polluted, which is easy to get pneumonia. Hong Song warned that children should not be allowed to live in air-conditioned rooms for a long time. Every morning and evening when the outdoor temperature is low, take the children to outdoor activities, breathe fresh air and strengthen their adaptability. [4]
What should the baby do if he gets air-conditioning disease?
[5] First of all, we should seize the first time. After the baby suffers from "artificial cold" in summer, there are always some signs, such as runny nose, stuffy nose, cough and fever. In this case, the mother should give the baby medication in time to control the condition and prevent it from developing. Second, help your baby sweat. The baby suddenly caught a cold, which led to a cold. The folk saying is "hold your sweat". The effective way is to make the baby sweat. Give your baby plenty of water, preferably boiled water and light salt water, which can help your baby sweat.

[Edit this paragraph] Treatment
causal treatment
In the season of frequent air conditioning, you should always open the window for air, and it is best to change it every two hours. According to the epidemic prevention department, it takes 10 minutes to open the window, and the air in an 80 square meter room can be changed again. Smokers should consciously not smoke in air-conditioned rooms. If you have a break, please be sure to stay outdoors for a while. People who specialize in this kind of occupation are equipped with photocopiers, printers and other equipment in air-conditioned rooms. They should open windows or install exhaust fans at work to ensure indoor air circulation. Don't stay in the air-conditioned room for a long time in hot summer. You can take advantage of the relatively low temperature in the morning and evening to do some outdoor activities.
medicine
Once you suffer from air-conditioning disease, you can take Huoxiang Zhengqi Water or Huoxiang Qushu Capsule for treatment, or you can choose the newly developed Iloco Yijin Jiedu Tablet or Jinhongsheng Compound Guazijin Granule for treatment. Besides, you can also drink some mung bean soup and watermelon Cui Yi soup for dietotherapy.
Dietotherapy air conditioning disease
Take fresh lotus leaf 100g, Pogostemon cablin 30g (dried product, fresh Pogostemon cablin 50g), add 800ml of water, boil for 20 minutes with slow fire, filter off the dregs, and take 500ml of the liquid medicine and cook it with Coicis Semen 100g into porridge. Take 1 dose in the morning and evening.
[Edit this paragraph] Impact
Low temperature environment will make blood vessels contract sharply, blood flow is not smooth, joints are damaged, and joint pain is caused. Because of the large temperature difference between indoor and outdoor, people often feel cold and hot when they go in and out, which will cause the dysfunction of the balance regulation system in the human body, which will cause headaches and easily catch a cold. The feeling of' cold' will also excite sympathetic nerves, which will lead to the contraction of blood vessels in abdominal cavity and the weakening of gastrointestinal movement, thus causing many corresponding symptoms. For women, cold stimulation will affect ovarian function and ovulation will be hindered, which is manifested as menstrual disorder. Negative ions in the air can inhibit the central nervous system of human body and play a role in regulating the functional state of cerebral cortex. However, the filter screen of air conditioner will absorb too much anions in the air, which will increase indoor cations. The normal ratio of anions to cations will cause physiological disorders and lead to clinical symptoms. Air-conditioned rooms are generally sealed, which makes the indoor air turbid, the bacterial content increases, the concentration of harmful gases such as carbon dioxide increases, and the density of negative ions beneficial to people decreases. If someone smokes indoors, it will further aggravate the deterioration of indoor air. Staying in such an environment for a long time is bound to make people dizzy.
[Edit this paragraph] Misunderstanding
Air conditioning was mistaken for a cold.
Usually when the air conditioner is turned on, the doors and windows are closed. At this time, the room is almost isolated from the outside world, and the indoor oxygen is constantly consumed without being replenished. The concentration of carbon dioxide in the air will increase and the air will become dirty. When people are in such an environment for a long time, their brains will suffer from hypoxia and air-conditioning diseases, mainly manifested as dizziness, fever, night sweats, physical weakness and so on. Many people mistake it for a cold.
Covering the quilt and blowing air conditioning can't prevent disease.
Blowing air conditioning under the quilt can only prevent cold, not disease. Some people turn down the air conditioning temperature after covering the quilt, but when they sleep, their metabolism slows down and they are more vulnerable to germs. Cold air enters the human body from the respiratory tract. After waking up, my nose and mouth are dry, I have headache, sneezing, runny nose, and even serious respiratory diseases.
Abuse of antibiotics to treat air-conditioning disease
It should be reminded that it is wrong to ask for transfusion and use anti-inflammatory drugs (antibiotics) once you have symptoms such as fever, stuffy nose, sore throat and cough after staying in an air-conditioned room for a long time. Deputy director Chen said that although colds are common diseases, they should not be used in their own experience. In the view of western medicine, colds are divided into viral infection and bacterial infection. Most colds are caused by viruses, and antibiotics are only needed when colds are complicated with bacterial infections.
[Edit this paragraph] Precautions
1. Household air conditioners can be cleaned and disinfected once a year by professionals, especially the evaporators of indoor units. Qualified disinfectants and correct proportioning methods must be used and operated by professionals. After disinfection, clean the residual liquid of disinfectant to prevent the volatilization of residual liquid from endangering health. During the use of the air conditioner, the filter screen should be cleaned frequently (directly with clean water), preferably once a week. 2. Before turning on the air conditioner, open the window for ventilation 10 minute, and try to let fresh outdoor air into the room. After turning on the air conditioner for a period of time, turn off the air conditioner and open the window for ventilation for 20 ~ 30 minutes. Repeatedly, indoor and outdoor air will form convection, and harmful gases will be discharged outdoors. 3. The indoor temperature should be controlled at about 25℃, and the indoor and outdoor temperature difference should not exceed 7℃; Don't point the air-conditioning outlet directly at people and tables. 4. It is easy to cause joint pain in a low-temperature air-conditioned room for a long time. In and out of the air-conditioned room, due to the large temperature difference between indoor and outdoor, it is prone to cough, headache, runny nose and other cold symptoms. In addition, because the filter screen of air conditioner can adsorb anions in the air, indoor cations increase, which has adverse effects on human body. 5. If the air conditioner is not cleaned regularly, it will accumulate dust and fibers and breed a large number of bacteria, viruses, molds and mites. When the air conditioner is turned on, these dust and pathogenic microorganisms are blown out by the air conditioner, causing indoor air pollution and disease spread. Among them, Legionella hidden in central air conditioning ventilation system is the most harmful and can cause Legionella disease. In addition, mites are strong allergens, which can cause allergic asthma, dermatitis, rhinitis and so on. 6. The respiratory system of the elderly is very weak. When using air conditioning, the air conditioning temperature should not be too low. When the weather is dry, you can use a humidifier or put a basin of water indoors. Before entering the room from the outside, dry the sweat on your body first. It is best to set the air conditioner regularly. 7. Children's immune function is low. When using the air conditioner, turn off the air conditioner half an hour before going out and open the window for ventilation to adapt to the indoor and outdoor temperature changes. [2] Effectively reducing the indoor and outdoor temperature difference can effectively prevent it.
