Thus, the humidity in the air-conditioned room is significantly lower than that outside, and the person is in the air-conditioned room. After a long time, you will feel dry nose and mouth, which can easily lead to nosebleeds, acute pharyngitis and other diseases. In addition, air conditioning is easy to breed bacteria, not easy to clean easily lead to mycoplasmal pneumonia, bronchial pneumonia and other diseases.

Children and women are susceptible people. The respiratory tract, joint muscles, and nervous system are the most susceptible.
What are the symptoms of air conditioning?
1, a cold
In summer, high temperature, many people have low air conditioning temperature due to chilliness. When people enter the air-conditioned room from the hot outdoor, the respiratory tract is easily stimulated, and when the sweat is clogged, the capillary suddenly shrinks rapidly and shrinks easily. It is easy to catch a cold. If you stay in the air-conditioned room for a long time, the pores are in a contracted state, suddenly come to a hot room or outdoors, the pores can not be opened in time, if the body adjustment center is improper, there will be heat stroke or sore throat, nasal congestion and other wind-heat type colds. symptom.
2, headache
In addition to causing colds, air-conditioning is also very serious for brain damage. The most common is headache. In summer, people work in the outdoor air and rush into the air-conditioned room. The skin feels hot and cold, especially when the indoor and outdoor temperature difference exceeds five. Above the degree, the blood vessels are inflated and contracted, and they contract rapidly from the dilated state, thus causing headache symptoms.

3, dry skin
When the air-conditioned room is too long, the skin is often dry and itchy. Especially suffering from chronic skin diseases, it is quite sensitive to temperature changes. Take common chronic skin diseases, atopic dermatitis, hot days, sweating, sweat stimulation Itchy skin is difficult, if it is in the air-conditioned room for a long time, the skin will be itchy due to too dry.
4, dry eyes
Drying problems in cold rooms also affect the eyes. People who wear contact lenses for a long time, people with chronic conjunctivitis or dry eye, are prone to dry eyes. If the cold air filter is not cleaned up in time, the situation is even worse. Closed office building, air conditioning system keeps circulating High concentration of carbon dioxide continues to accumulate in the air, and the eyes are staring at the computer screen for a long time in the absence of oxygen, which is prone to redness and itching.

How is air conditioning disease caused?
1. alternating hot and cold
The biggest 'criminal' of air-conditioning disease is the large temperature difference. Tang Ronghui mentioned that the temperature in the air-conditioned room is low, which will cause the blood vessels to shrink rapidly, the blood flow is not smooth, and the gastrointestinal movement is weakened, resulting in a series of problems. From 30 °C above the outdoor Go to the air-conditioned room, then go out from the air-conditioned room to the outside, often go in and out, the body is hot and cold, the autonomic nervous system that regulates body temperature is difficult to adapt, and the body is prone to problems.
2. The air is impassable
The air-conditioned room is usually closed, people stay inside, constantly breathing to emit carbon dioxide, and the indoor oxygen is continuously consumed and not replenished, the concentration of carbon dioxide in the air will rise, the air becomes dirty, and people stay in the room for a long time. In such an environment, it is easy to feel tired and dizzy.
3. Air drying
The air in the air-conditioned environment is very dry. Tang Ronghui said that this will make the skin dry and tight, easily affecting the respiratory mucosa, resulting in decreased local immunity. Especially for the elderly or patients with underlying diseases such as chronic obstructive pulmonary disease, it is easy to induce acute disease or Make the condition worse, and even cause lung infection.
4. Negative ion reduction
Staying in the air-conditioned room will cause a lack of spirit, which has a lot to do with the reduction of negative ions in the air. The negative ions in the air are also called 'vitamins in the air', which can make people feel refreshed. In airtight air conditioning In the room, the lack of negative ions, the most intuitive feeling is that the air is not fresh. After a long time, people will feel chest tightness, palpitation, dizziness and weakness, the result is a decline in work efficiency and health.
5, dust and other indoor allergens stirred
Air blown by air conditioners may cause dust and other indoor allergens on the air filter to be stirred up. Children with respiratory allergies are very susceptible to the disease after inhaling these allergens. In addition, sudden inhalation of cold air may induce airway contraction in allergic infants. Induced allergy symptoms.
6, virus pathogen reproduction
The air duct of the air conditioner, the hair dryer is suitable for the survival and reproduction of the virus, and the germ virus is blown out by the air conditioner, which is easy to cause a large-scale infection.
