What to do if you cough when using air conditioning

Some people are prone to coughing when they use air conditioning. For such people, you must pay attention and try to use air conditioning less. In addition, you need to find out the reason for coughing when using air conditioning. The most common reason is that the indoor air is too dry and the air is not particularly fresh. In addition, some people have certain problems with their trachea, and are stimulated by cold air, which often causes coughing symptoms. There is another situation that also needs attention. The air conditioner should be cleaned regularly. If it is not cleaned for a long time, too many germs will accumulate in it, which will also induce coughing.

Reason 1: Dryness

Coughing when using air conditioning may be caused by the air in the air-conditioned room being too dry. The air conditioner will remove some moisture from the air during the cooling process, so the air in the air-conditioned room will be relatively dry. People in such an environment will have weaker body resistance. 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 have symptoms such as hoarseness. This is a "dry cough."

Reason 2: Cold air stimulation

Coughing when using air conditioning may also be caused by the temperature in the air-conditioned room being too low, causing the cold air to irritate the trachea. 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, their 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 latent bacteria and viruses in the body to accelerate, leading to increased throat secretions, irritation of the trachea and causing coughing. In addition, cold air irritates the trachea and causes the respiratory smooth muscles to contract, leading to bronchial constriction and stimulating cough receptors, causing symptom attacks.

Reason 3: The air conditioner has not been cleaned for a long time

Coughing when using the air conditioner may also be caused by the air conditioner at home not being cleaned for a long time. Because if the air conditioner has not been cleaned for a long time, there will be a lot of dust and mites on the air conditioner filter. When the air conditioner is turned on, the dust, mites and other allergens on the air conditioner filter will be stirred up. When these bacteria, dust, mites, etc. come into contact with the human body, they may induce asthma and allergic cough.

Reason 4: Cough has not healed

If you start coughing when you use the air conditioner, you may think that the cough has not healed. Many people stop coughing after a period of treatment after catching a cold, but because of the long period of coughing, their bodies are still relatively weak and their immunity is poor. They need to avoid all kinds of stimulation. Therefore, suddenly going from a hot environment to a cold environment is likely to induce coughing again.
