Friend, this is a manifestation of air conditioning disease. With the hot weather, more and more families and places use air conditioners now. "Air-conditioning disease" is not a new term. I believe many people have had this feeling. If you stay in an air-conditioned room for a long time, you will feel dizzy and thirsty. If the air conditioning temperature is too cold, you will feel tight all over, your hands and feet will be cold, and you will have backache after a long time. Sometimes, when someone enters the air-conditioned room from the sultry outdoor and suddenly cools down, some people will feel uncomfortable and even have diarrhea. If you often go in and out of air-conditioned rooms and go out in hot weather, some people will catch a cold ... Experts point out that these are all manifestations of "air conditioning disease". Improper use of air conditioning can lead to cervical spondylosis. Every summer, the emergency department of the hospital will treat patients with air-conditioning disease, and the patients who come to see the doctor are more serious. Generally speaking, the symptoms of patients include cough, headache, runny nose and other cold symptoms, while others may be manifested as weakness of limbs, cold hands and feet, backache, low work efficiency, thirst, loss of appetite, diarrhea and so on. However, patients with serious illness have respiratory failure or even coma when they come to see a doctor, and have been diagnosed as Legionella pneumonia. Cold stimulation and long-term bad posture are the two main reasons for inducing and aggravating cervical spondylosis. Working and studying in a low-temperature air-conditioned room for too long, especially when the neck is directly exposed to cold wind or suddenly stimulated by cold, the neck blood vessels contract and the muscles are highly tense, which makes the neck muscles, nerves, blood vessels and other tissues involved. Over time, it causes local arthritis, fasciitis, cervical artery spasm or insufficient blood supply, and presents symptoms such as headache, dizziness and nausea. Methods to prevent "air conditioning disease"-1. Pay attention to the high temperature. If you often go in and out of the air-conditioned room, the temperature must be too high. For example, turn up the temperature or turn off the air conditioner first, and you must dry your sweat first when you enter the door. Stay in an air-conditioned room for a long time, drink as much water as possible, and often mop the floor with a mop filled with water to moisturize. 2. Strengthen air circulation and try to avoid staying in air-conditioned rooms for a long time. The temperature difference between indoor and outdoor exceeds 7 degrees. It is best to turn off the air conditioner for a period of time and open the window to breathe fresh air after turning on 1 to 3 hours. For the driver, if the car is extremely hot, you should open the window first, and then turn on the air conditioner after exhausting the hot air. The temperature can't be too low, so it's best not to smoke. Besides, don't sleep in the car with the air conditioner on. If the carbon monoxide emitted by the engine leaks into the car, it is easy to be poisoned. Take a hot bath and do more exercise. People who often sit and work may wish to prepare a set of long-sleeved trousers in the company, especially young women. It is best to protect the joints of your knees with towels or thick clothes, and stand up and exercise every once in a while. After coming home from work, take a warm bath to keep the water from overheating, then massage yourself, or apply a warm towel to your joints. It would be better if you could exercise properly. The above is the common sense to prevent air-conditioning diseases. Now let's take a look at some preventive measures that experts told Bian Xiao. 1. Do not set the temperature too low. Generally, it is advisable to keep the air conditioning temperature at around 24 degrees Celsius, so that the indoor and outdoor temperature difference does not exceed 7 degrees Celsius. 2. No matter the desk or bed in the living room, keep away from the air conditioner. The closer to the air conditioner, the faster the velocity of cold air and the greater the impact. People who work in air-conditioned rooms for a long time should add some clothes that are convenient to put on and take off, and cover their knees with bath towels, knee pads and other warm items. 4. Take a shower after coming home from work, and the water pressure should be raised. You can do full-body hydraulic massage or post-bath massage, and you can also use a massager to restore blood circulation. It is reasonable to sweat in summer, so you don't have to leave the air conditioner all the time. Avoid strong sunlight outdoors and do some soothing exercises, one is to relax muscles and promote blood circulation, and the other is to dispel wind and remove dampness. 6.
