No, air conditioning is not inherently good for your lungs, and in some cases, it can worsen lung conditions. While AC can remove some particles from the air, it can also negatively impact lung health.
How Air Conditioning Can Affect Lungs

Cold Air Irritation: A/Prof Morgan highlights that cold air from air conditioners can irritate the upper (nose/throat) and lower airways. This is especially true for those with pre-existing inflammation or swelling in their airways, potentially triggering chest tightness and coughing. [11-Feb-2021]

Worsening of Existing Conditions: For individuals with conditions like bronchiectasis, the cold air from AC can exacerbate symptoms such as coughing.

Dry Air and Irritation: Air conditioning removes moisture from the air, leading to dry nasal passages. This dryness can trigger or worsen asthma and allergies. [HelloDoctor]
-
Mold and Bacteria: Dirty air conditioning filters can harbor mold and bacteria, increasing the risk of respiratory infections. [Verywellhealth, KCR, Inc.] Old, poorly maintained units pose an even greater risk. [KCR, Inc.]

Hypersensitivity Pneumonitis ("Air Conditioner Lung"): In rare cases, exposure to contaminated air conditioning systems can lead to hypersensitivity pneumonitis, an inflammatory lung disease. [AHS]
Maintaining Lung Health with Air Conditioning
To mitigate the negative effects of air conditioning:
- Keep the temperature moderate: Avoid excessively cold settings.
- Use air purifiers: Supplement your AC with a good air purifier to remove additional pollutants.
- Maintain clean filters: Regularly clean or replace your AC filters to prevent mold and bacteria growth.
- Ensure proper ventilation: Don't completely seal off your space; allow for some fresh air circulation.
- Hydrate: Drink plenty of fluids to combat dry air.
It's important to note that while air conditioning may not be directly beneficial to lung health, managing its use and maintaining proper unit upkeep can minimize negative impacts, particularly for those with pre-existing respiratory conditions.
