Why Does Air Conditioning Make Me Cough?

Air conditioning systems work by drawing in hot air from the surrounding environment, cooling it down, and then blowing it back out into the room. While this process can be incredibly effective at lowering the temperature, it can also have some unintended consequences. One of the main reasons why air conditioning can make you cough is due to the way it affects the air's humidity levels. 

When the AC system cools the air, it also removes moisture from the air, leading to dryness and low humidity. This can be particularly problematic for people who already have respiratory issues, such as asthma or chronic bronchitis. Dry air can irritate the mucous membranes in the throat, nose, and lungs, causing inflammation and discomfort. Additionally, the low humidity can also make the air feel colder than it actually is, which can further exacerbate coughing.

In addition to dry air, poor air quality and allergens can also contribute to coughing fits when using air conditioning. If your AC system is not properly maintained, it can harbor a buildup of dust, pollen, and other airborne particles. These particles can then be blown back into the air, aggravating respiratory issues and triggering coughing. 

Furthermore, if your AC system is not equipped with a proper air filter, it can allow allergens and irritants to circulate in the air. This can be especially problematic for people who suffer from allergies or have sensitivities to certain airborne particles. 

Another factor that can contribute to AC-related coughing is the presence of irritants in the air. These can include chemicals, cleaning products, and other volatile organic compounds (VOCs) that can be present in the air. When these irritants are blown through the AC system, they can cause inflammation and irritation in the throat, nose, and lungs, leading to coughing. 

Finally, inadequate AC maintenance can also play a role in AC-related coughing. If your AC system is not regularly serviced, it can lead to a buildup of debris, dust, and other particles that can cause coughing. Additionally, a poorly maintained AC system can also lead to reduced airflow, which can cause the air to become stale and stagnant, further exacerbating coughing. 

Fortunately, there are several solutions that can help reduce AC-related coughing. Here are a few: 

• Using Humidifiers: One of the most effective ways to combat dry air is to use a humidifier. By adding moisture back into the air, you can help alleviate dryness and irritation in the throat, nose, and lungs. 

• Changing Air Filters: Regularly changing your air filters can help improve air quality and reduce the presence of allergens and irritants in the air. 

• Regular Maintenance: Regularly servicing your AC system can help prevent the buildup of debris and dust, which can contribute to coughing. 

• Adjusting the Thermostat: Adjusting the thermostat to a comfortable temperature can also help reduce coughing. If the air is too cold, it can cause dryness and irritation in the throat, nose, and lungs. 

• Using a Dehumidifier: If you live in a humid climate, using a dehumidifier can help remove excess moisture from the air, which can help reduce coughing. 

Preventing AC-related coughing is key to avoiding discomfort and distress. Here are a few tips to help you prevent AC-related coughing: 

• Proper AC Installation: Make sure your AC system is properly installed and maintained to prevent issues. 

• Regular Maintenance: Regularly service your AC system to prevent the buildup of debris and dust. 

• Air Filter Maintenance: Regularly change your air filters to improve air quality and reduce the presence of allergens and irritants in the air.
