The symptoms of air conditioning disease are far from air conditioning disease.

Qingyu is an urban female white-collar worker. Recently, she found her hands numb from time to time. An attack lasted all afternoon. In severe cases, her palm is like countless ants crawling and biting, pressing her fingertips hard, and she is completely unconscious. Because it is an accidental attack, it has little impact on life. Qingyu didn't take it seriously at first, but in retrospect, it seems that this happens every summer in recent years. I was afraid that something was wrong, so she decided to take time to see a doctor. After the consultation, the doctor quickly diagnosed that she was suffering from air conditioning.

What is air conditioning disease?

The great invention of air conditioning has brought people rare coolness and relaxation in the hot summer, but it has also brought a disease that is not "relaxed and free"-air conditioning disease, which is called "air conditioning syndrome" in medicine.

Some scholars believe that air-conditioning diseases are mainly caused by being in a closed space, the air is not circulating, the indoor air quality is deteriorating, or the volatile organic compounds, microbial allergens, noise and other comprehensive factors in the indoor air. From the perspective of traditional Chinese medicine, it is caused by the invasion of external evils and the imbalance of yin and yang in the human body. Under normal circumstances, moderate use of air conditioning will not cause disease, but if air conditioning is used unchecked, people's bodies will not be able to adapt to this environment, leading to imbalance between yin and yang and cause disease.

Every summer, the hospital will treat many patients with air-conditioning diseases, most of which are manifested as nasal congestion, dizziness, sneezing, dry throat, tinnitus, stinging eyes, skin allergies and other symptoms. It seems that the temperature difference between indoor and outdoor is too large, but the real germs are actually fine particles flying around in the air conditioner. This is PM2.5, which has received much attention this year.

Legionella is harmful.

Li Tian, director of the Second Department of Respiratory Medicine of Nanjing Chest Hospital, said that Legionella caused by Legionella is the most harmful disease to human body. Legionella first conquered the human body's "fragile defense line"-respiratory tract, causing infection. Its main symptoms are persistent high fever, cough and excessive phlegm, which are very similar to common pneumonia caused by other pathogens. It is understood that "Legionella" spreads in the form of aerosol (particles slightly larger than the gas formed after water evaporation) through air conditioning vents, which makes people in the house infected. Therefore, if the air conditioner is not cleaned frequently, it will easily become a paradise for Legionella.

It is reported that this disease is very dangerous because it is difficult to diagnose, because the patient's sputum must be cultivated for more than seven days before a definite diagnosis can be made. Because of the high requirements, ordinary hospitals do not have this ability.

Although the probability of suffering from Legionella disease is lower than other air-conditioned diseases, once suffering from Legionella pneumonia, it will be very terrible. The mortality rate of this disease is 30% in normal people without immunodeficiency, which can be reduced to 5% after treatment. And if people's immune function is low, this number will soar to 70%.

Common symptoms and preference groups

The common symptoms of air conditioning disease are: cold, allergy, rheumatalgia, mucous membrane dryness; Nervousness, irritability, difficulty in concentration and headache; Dizziness, dizziness, nausea and vomiting, loss of appetite and poor sleep; Thirst, sore throat, listlessness, backache and dry skin; Cold hands and feet, even numbness, irregular menstruation, diarrhea or constipation.

Air-conditioning diseases favor four types of people: first, children, especially infants. Children have poor thermoregulation function and weak resistance. Staying in an air-conditioned room for a long time is prone to symptoms such as colds and fever. There are old people. "Old cold legs" are common in winter, but with the popularity of air conditioning, many people stay in air-conditioned rooms for a long time and induce old cold legs in summer. Then there are office white-collar workers. In the low temperature environment of air-conditioned room for a long time, it is easy to damage the neck, shoulders and muscle fibers, especially the beauty-loving women who often wear strapless clothes, which is easy to induce scapulohumeral periarthritis, and then lead to cervical degeneration; In addition, drivers and motorists are also prone to air-conditioning diseases. When the air conditioner works, the air displacement in the car is 2 ~ 5 times more than usual, and some even reach 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. Precautions to stay away from air conditioning disease

Keep the room ventilated and keep the air circulating.

The difference between the room temperature of the air conditioner and the outdoor natural temperature should not be too big, 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.

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 cold air directly when sweating.

Pay attention to replenish water. Don't think that you won't lose water without sweating. In fact, the human body evaporates water invisibly in an air-conditioned room.

If you stay in an air-conditioned room all day, take a hot bath at night, massage your whole body and relax your joints and muscles. It would be better if you can exercise properly to avoid stiffness and discomfort.

Don't smoke indoors and don't use air fresheners, which will aggravate indoor air pollution.

When going out from 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 stay in an air-conditioned room for a long time, do more outdoor activities.

Keep the skin clean and hygienic, because of frequent contact with air-conditioned environment and sudden changes in heat and cold, bacteria attached to the skin are easily blocked in sweat glands or sebaceous glands, causing infection and suppuration.

Add a dehumidifier to the air conditioner to prevent bacteria from breeding.

Household air conditioners can be cleaned and disinfected once a year by professionals, especially the evaporators of indoor machines. During use, the filter screen should also be cleaned frequently (directly with clean water), preferably once a week.

The respiratory system of the elderly is weak, so the air conditioning temperature should not be too low when using air conditioning. When the weather is dry, you can use a humidifier or put a basin of water indoors.

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.

Ladies who like to wear suspenders may wish to prepare a shawl in the office, get up every hour to move their limbs and improve peripheral blood circulation.

Don't turn on the air conditioner for a long time in a stationary car, in case the carbon monoxide discharged from the automobile engine flows back into the car and an accident occurs, resulting in carbon monoxide poisoning.

People who often stay in air-conditioned rooms drink more ginger soup, which can effectively prevent the occurrence of air-conditioned diseases.

Conditioning of air-conditioning disease

You can massage Dazhui, Zusanli and Yinlingquan.

Dazhui is the intersection of the three Yang meridians of the hands and feet and the Du meridian. However, the Du meridian is also the unified Du meridian of all yang, and yang dominates the exterior. Pressing hard can dispel the summer heat. Yinlingquan point is the point of foot Taiyin spleen meridian, and it is a common point for eliminating dampness. Zusanli point is the acupoint of Foot Yangming Stomach Meridian, while Foot Taiyin Spleen Meridian and Foot Yangming Stomach Meridian are in exterior and interior, which can strengthen the spleen and stomach, clear away dampness and turbidity.
