Air conditioning can indeed worsen asthma symptoms. Asthma is an inflammatory condition of the airways, which can be triggered by environmental factors including temperature, humidity, and air pollutants. Air conditioning can worsen asthma symptoms by making the air dryer, as air conditioners remove moisture from the air. This can irritate the airways, leading to coughing, wheezing, breathlessness, and chest tightness.
In addition, air conditioners can also spread dust, dirt, mold, and other particles that can trigger asthma in some people. This is especially true in air conditioners that are not properly maintained, as dust and particles can accumulate in the filters and ducts, and then be circulated through the air.
Finally, air conditioning can worsen asthma symptoms by cooling the air too quickly and dramatically, which can cause an asthma attack. This is especially true for people who already have narrowed or blocked airways caused by asthma.
Overall, air conditioning can worsen asthma symptoms in some people, especially if the air conditioner is not properly maintained. It is important to keep the air conditioner clean and to monitor the temperature and humidity in the room to ensure that they stay at optimal levels for asthma sufferers.
