Cough caused by air conditioning

People all have a problem. They miss winter in summer, thinking that winter is just a little colder; when winter comes, they start to miss summer again, thinking that although summer is hot, it is beautiful, they don’t need to wear too many clothes, and it is very convenient to move around. Many friends in the south have turned on the air conditioner in spring because summer comes earlier in the south. The following are some reasons for coughing caused by air conditioning. You can learn about them~

What is the reason for coughing when using air conditioning? The filter on the air conditioner should be cleaned in time to prevent pathogenic microorganisms from multiplying and growing on the filter and causing harm to the human body. In addition, it is best to fumigate the air-conditioned room regularly.

1. If there are no other problems during the physical examination, the problem may be with the air conditioner.

The first thing to do when using air conditioning is to prevent dust. The heat sink is a must-pass place for air in the air conditioner. Dust and dirt in the air continue to accumulate on the heat sink. Coupled with the humid environment caused by the condensation water of the air conditioner and the suitable temperature when the air conditioner is running, dust mites breed in large numbers. Many office buildings have dry environments and low humidity, which makes it easy for viruses and bacteria to multiply. When people stay in an air-conditioned room for a long time, dust mites and germs can harm the human respiratory system and immune system, causing a variety of air-conditioning diseases such as coughing, dizziness, fatigue, upper respiratory tract diseases, pneumonia, and skin allergies.

Therefore, it is recommended not to use the air conditioner for too long and to open the windows frequently to ensure air circulation and keep the indoor air clean. In addition, rooms using air conditioners should be kept clean and hygienic, and smoking should be avoided indoors. If you heat white vinegar and make it evaporate, you can purify the air.

2. The air conditioning temperature is too low

Low temperature and dryness can easily cause "dry cough". Frequent use of air conditioners can dehumidify the room and reduce indoor humidity. In such an environment, people's body resistance will weaken. Over time, the originally moist and healthy throat will become dry, the throat will become red and swollen, and you will cough from time to time, and sometimes you will experience symptoms such as hoarseness. This is a "dry cough".

In addition, when people stay in a low-temperature air-conditioned room for a long time, the human body's blood vessels will contract. When people suddenly walk out of the air-conditioned room, the body's blood vessels will rapidly expand. The blood vessels are between contraction and expansion, which will cause the local capillary blood supply capacity to decrease, the body's local immunity to decrease, and the reproduction rate of bacteria and viruses to accelerate, leading to increased throat secretions, irritation of the trachea and causing coughing. Cold air irritates the trachea and causes the smooth muscles of the respiratory tract to contract, leading to bronchial constriction and stimulating cough receptors, causing symptoms.

Therefore, it is recommended not to stay in the air-conditioned room for a long time, the air-conditioning temperature should not be adjusted too low, and the indoor humidity should be maintained. Be sure to drink plenty of water to keep your throat moist. You can boil honeysuckle, chrysanthemum, raw rehmannia, etc. in water and drink it as tea, which not only clears away heat and detoxifies, but also prevents bacterial invasion. You should drink more refreshing drinks in your daily life, such as chrysanthemum tea, honeysuckle tea, mung bean soup, lotus seed and black fungus soup, etc. Patients with a history of chronic pharyngitis should also receive appropriate intervention to reduce the occurrence of inflammation. In addition, avoid smoking, drinking, and eating too cold or too hot food that irritate the throat. Do not stay up late, live a regular life, learn to reduce stress on your own, and keep your mood happy.

"Air-conditioning cough" generally does not require medication. For "air-conditioning cough", do not rush to take cough suppressant Chinese medicine, because the secretions of the lower respiratory tract, namely sputum, can only be discharged from the body through coughing. If antitussive drugs are used, the cough reflex will be inhibited, resulting in retention of sputum in the trachea and bronchi, which will aggravate the condition or cause secondary infection.

Therefore, it is recommended that if you experience "air-conditioning cough", it can generally be alleviated by taking measures such as preventing dust and dryness, and using the air conditioner less. If the cough persists, be alert to cough variant asthma and seek medical attention promptly.
