　　In modern life, in summer, air conditioning can drive away the scorching heat of summer and bring a touch of coolness to work, study and life. It is a very pleasant thing. Air conditioning is a "cool messenger" and also a "shadow killer". While air conditioning brings comfort to people, it also brings danger signals to people. If you are not careful, it will cause some disease haunted.

　　Since the beginning of summer this year, many provinces and cities in southern my country have suffered heavy rains and floods. Days of rain have immersed the entire south in a dark and humid environment. As the heavy rains pass, we finally see the sunshine that we have not seen for many days. The temperature will gradually rise, so the use time of air conditioners will also increase. While air conditioners bring coolness to people, they also bring hidden dangers to people. If you are not careful, you will get some diseases. south Hospital Dr. Lai from the respiratory department received 39 healthy An exclusive interview with the website specifically pointed out: After a heavy rain, be careful of suffering from "air conditioning disease".

　　Many netizens ask what is air conditioning disease?

　　In modern life, in summer, air conditioning can drive away the scorching heat of summer and bring a touch of coolness to work, study and life. It is a very pleasant thing. Air conditioning is a "cool messenger" and also a "shadow killer". While air conditioning brings comfort to people, it also brings danger signals to people. If you are not careful, you will be plagued by some diseases. There is a large temperature difference between the air-conditioned room and the outdoors. If people often go in and out of the air-conditioned room, it will cause cough , headache, runny nose, etc. cold symptoms. People who often use air conditioners in the summer season often have the above experience. If you stay in an air-conditioned room with a low temperature for too long and wear thin clothes, it will cause joint pain, stiff neck and back, heavy waist and hips, numbness in the limbs and feet, stiff joints, dizziness and brain swelling, or numbness in the shoulders and neck. If you stay in an air-conditioned room for too long, the bad air may make you dizzy. These symptoms are air conditioning syndrome, commonly known as air conditioning disease.

　　Why do people suffer from air conditioning disease, and how to explain it from a pathophysiological perspective?

　　First of all, a low-temperature environment will sharply constrict blood vessels, causing poor blood flow, and joint damage and coldness will cause joint pain; due to the large temperature difference between indoors and outdoors, people often feel hot and cold when they come in and out frequently. The body's temperature regulation system is dysfunctional, and imbalance will cause cold symptoms such as headaches, coughs, and runny noses. The "cold" feeling can also cause sympathetic nerve Excitation leads to intra-abdominal vasoconstriction and weakened gastrointestinal motility, thus causing a lot of discomfort.

　　Secondly, in air-conditioned rooms, the direction of airflow changes frequently, the airflow speed increases, and the heat of the air changes continuously. These factors interfere with the human body's sense of smell and weaken the body's response to germs, allergens and odors in the air. Due to the presence of air conditioning, the humidity in the room is too low, which will have adverse effects on the mucous membranes of the human body's eyes, nose, etc. Causes mucosal disease. Sometimes, because the air-conditioned room is dry and the temperature is suitable, germs and viruses are easy to survive in the air. The air ducts and hair dryers of air conditioners are also suitable for germs and viruses to survive and reproduce. Germs and viruses are blown out by the air conditioner, which can easily cause large-scale infections. Anions in the air can inhibit the central nervous system of the human body and play a role in regulating the functional status of the cerebral cortex. However, the filter of the air conditioner can absorb too many anions in the air, causing an increase in cations in the room. The imbalance of the normal proportion of anions and cations causes physiological disorders of the human body, leading to symptoms. clinical symptom. Air-conditioned rooms are generally sealed, which makes the indoor air turbid, increases the bacterial content, increases the concentration of harmful gases such as carbon dioxide, and reduces the density of negative ions that are beneficial to people. If there are people smoking indoors, it will further worsen the indoor air. Staying in such an environment for any length of time is bound to make you dizzy.

　　Thirdly, the noise from air conditioners can also interfere with the nervous system. If the arrangement of air conditioners is not scientific when designing interior decoration, these problems will be more prominent. Using air conditioners will reduce ozone in fresh air. Usually low-concentration ozone can inhibit bacterial reproduction, and high-concentration ozone has a disinfecting effect. However, the ozone concentration in air-conditioned rooms is extremely low or almost non-existent, which increases the symptoms of air-conditioning sickness.
