What harm will air conditioning be blown for a long time in hot weather?

People who work and study in air-conditioned environment for a long time are prone to breed pathogenic microorganisms because of the relatively closed space and poor ventilation, and the temperature difference between indoor and outdoor is large, so their bodies are not adapted, and they may have symptoms such as stuffy nose, dizziness, sneezing, tinnitus, fatigue, memory loss, pain in muscles and joints of limbs, and often have some symptoms of skin allergy, such as tight and dry skin, allergy and skin deterioration. This phenomenon is called "air conditioning syndrome" or "air conditioning disease" in modern medicine.

1, adjust indoor and outdoor temperatures:

The indoor temperature should be kept at about 25℃, and the temperature difference between indoor and outdoor should not exceed 7℃. Air-conditioned rooms should be kept clean and hygienic, and should not be placed in places where cold air blows directly. It is necessary to appropriately increase the clothes that are convenient to put on and take off, and the knees can be covered with towels for protection. At the same time, stand up and walk occasionally to keep normal body temperature, so as to promote blood circulation of limbs and enhance body resistance. Working in an air-conditioned room for a long time, it is necessary to appropriately increase the clothes that are convenient to put on and take off. When wearing a short skirt, cover your knees with a soft towel. At the same time, we should pay attention to intermittent standing activities to improve peripheral blood circulation.

2. Keep the indoor air fresh:

Because there are few windows with natural ventilation, the air circulation is not very good. Many office buildings have closed doors and windows because of the nature of their work or other problems, and rely entirely on air conditioners to regulate temperature and air circulation. Coupled with the release of some toxic and harmful gases in decoration materials, it is difficult to dissipate in the air as soon as possible, which will cause greater harm to the human body. Therefore, in order to prevent air-conditioning diseases, it is necessary to open the window frequently for ventilation, and it is best to turn it off after 1~3 hours, and make more use of natural wind to reduce the indoor temperature. The air-conditioned room should be ventilated regularly, and the indoor air should be disinfected to keep the room clean and reduce the chances of bacteria and other microorganisms in the air conditioner. You can't sleep at night with the air conditioner on all night, and the position of the bed should keep a certain distance from the air outlet of the air conditioner.

3, strengthen air conditioning maintenance:

Air conditioners and other electrical appliances are also sources of pollution. At least 10,000 mites were blown out by dirty air conditioners. The filter screen of air conditioner will absorb too many anions in the air, so that the anions that can inhibit the central nervous system of human body and regulate the functional state of cerebral cortex are reduced, and the normal proportion of indoor anions and cations is out of balance, which leads to physiological disorders and clinical symptoms. Air conditioning filters and cooling coils should be cleaned frequently to prevent the growth of bacteria, viruses and other microorganisms. Suspended substances and mites in indoor air are easy to induce respiratory diseases, and rooms with air conditioning and carpets are the best environment for mites to survive. Therefore, it is best to configure air purifiers in air-conditioned rooms to improve indoor air quality.

4, diet, drugs:

In the daily diet, the amount of spices such as ginger, Schizonepeta tenuifolia, perilla leaf and pepper can be appropriately increased, which can not only play an appetizing role, but also prevent cold, enhance the body's resistance and prevent air-conditioning diseases. At ordinary times, you should always prepare some standing medicines at home to protect your health.

5. Proper plant cultivation is beneficial:

A simple and wonderful way is to put green plants in the office area. Studies show that aloe can eliminate 90% formaldehyde in 1 m3 air under 24-hour illumination. Plants such as chlorophytum, aloe and chrysanthemum can absorb harmful substances.

6. At the same time, we should pay special attention to the following small details:

1), the indoor air velocity should be kept at about 20 cm per second, and the desk must not be placed in the cold wind, because the air flow there will drop by 3-4 degrees Celsius.

2), don't open for a long time, usually a fixed time of about 2 hours.

3) Be careful not to stay in the air-conditioned room when sweating.

4) When you come home from work, take a hot bath and massage yourself first. It's certainly better if you can exercise properly.

5) After installing the air conditioner, pay attention to the elderly and babies, because their temperature perception is poor and their body temperature regulation is poor. Don't pay unnecessary price for enjoyment.
