Air conditioning has become a necessity for modern families, which can cool down and prevent heatstroke and provide a comfortable and cool rest and working environment. However, if you stay in an air-conditioned room for a long time, or if the air conditioner is improperly used, you will suffer from "air conditioning disease", with symptoms such as dizziness, headache, chills, limb pain, and decreased work efficiency.
Causes of air conditioning disease:
The air provided by an air-conditioned room is repeatedly circulated, cooled or heated, dehumidified or humidified before flowing into the room. This air is not fresh air. Some low-concentration harmful substances in the air accumulate due to circulation, which is harmful to human body. At the same time, the number of negative ions of oxygen decreases, and there are too many positive ions, causing endocrine disorders, dizziness, headache, fatigue, loss of appetite, palpitation and chest tightness. Because women have poor tolerance to low temperature, they have severe symptoms of air conditioning, which leads to muscle aches all over the body.
The environment in the air conditioner is very suitable for the reproduction of microorganisms such as bacteria, fungi and viruses. For example, bacilli and other pathogens that cause legionnaires' disease can be separated from the cooling water of air conditioning systems.
If the difference between indoor and outdoor environment (temperature, humidity, airflow, etc. ) is too large, it is difficult for people to adapt, and it is easy to cause colds and nasal sensitivity. Indoor dryness will stimulate the respiratory tract, make the nasal cavity and nasal mucosa easily inflamed and reduce resistance. Commonly used circulating air, resulting in reduced indoor and outdoor air exchange, dirty air, easy to spread germs.
Air-conditioned rooms often lack natural light and cannot kill indoor bacteria and viruses.
Improvement measures:
Clean and replace the dust screen frequently to prevent the growth of bacteria and viruses.
When you are sweating all over, don't go into the air-conditioned room immediately, lest your pores suddenly contract and catch a cold.
Try to reduce the temperature difference between indoor and outdoor, and keep the room temperature at 25-27 degrees Celsius.
Don't open windows in air-conditioned rooms.
Block it and let the sun shine into the room.
The face should not be directly facing the air conditioner, because the blood vessels and nerves of facial tissue are strongly stimulated by cold, otherwise it may lead to nerve ischemia and hypoxia, and then paralysis, affecting facial muscles.
Don't stay in the air-conditioned room for a long time. You should go outdoors, exercise your muscles and breathe some fresh air. You should do some outdoor activities to give your skin a chance to sweat, keep your pores open and speed up your metabolism.
