However, many people get stuffy nose, runny nose, cough, fatigue and dry throat when they blow air conditioners. When they leave the air-conditioned room, all the symptoms will disappear naturally.
Can you get sick by blowing air conditioning? What the hell is going on here? Below, "seeking medical treatment" will tell you something.
Air conditioning refrigeration depends on the cold air blown by the indoor unit. In this process, the water vapor in the indoor air condenses into water droplets in the evaporator and flows to the outside along the drainage pipe, so that the indoor air will become dry.
In addition, in order to maintain the cooling effect of air conditioning, we usually close the doors and windows when turning on the air conditioning. At this time, dry air, low temperature, poor air circulation and indoor air pollution are the main causes of "air conditioning disease".
(1) dizziness and headache
In summer, the outdoor temperature is high. As long as people can meet an air-conditioned room, people will rush in. Especially when the temperature difference between indoor and outdoor is great, blood vessels will expand with heat and contract with cold, and nerve plexus will contract sharply, which is prone to dizziness, headache and other symptoms.
Moreover, the closed environment of air-conditioned rooms will lead to the increase of indoor carbon dioxide content and aggravate headaches.
(2) Dry and cold skin
Air conditioning reduces the indoor temperature, and with the decrease of temperature, the water content of human skin and mucosa also decreases accordingly. Moreover, it is easier to catch a cold in an air-conditioned room, because the cold virus has stronger survival ability in a dry environment, and the dry skin mucosa is more vulnerable to the cold virus.
(3) Joint pain
In summer, people generally wear less. The indoor air conditioner blows badly. Thin clothes can easily stimulate the sharp contraction of blood vessels, leading to poor blood circulation, joint injury, cold, pain, stiff neck and back, pain and numbness in waist and limbs.
(4) Allergy and asthma
If the indoor air is not circulating, and you are allergic, it may cause rhinitis, itchy eyes, headache, dizziness and difficulty breathing. More seriously, it may also lead to pneumonia or asthma.
(5) Resistance decreased
Rooms that have been air-conditioned for a long time have a certain degree of air pollution. Volatile gases such as furniture, electrical appliances and corrupt garbage, and pathogens such as cigarette smoke, bacteria, germs and molds will pollute indoor air, reduce human immunity and make people sick.
(1) Be sure to drink plenty of water in the air-conditioned room;
(2) Indoor ventilation is often needed to ensure indoor and outdoor air convection;
(3) The air conditioning temperature must be appropriate, and it is best to control it between 26 and 28 degrees. The temperature difference between indoor and outdoor should not exceed 7 degrees, and the wind speed should not be too large;
(4) The blades in the air conditioner must be cleaned frequently, and dust will be harmful to the body. If necessary, you can also ask someone to carry out maintenance;
(5) Always pay attention to moisturizing in air-conditioned rooms. It is most appropriate to put a basin of water indoors or use a humidifier to keep the humidity at 40% ~ 60%. Under this humidity, the pathogenicity and transmission ability of pathogens will decline rapidly. .
