How Air Conditioners Affect Your Respiratory System
Air conditioners can affect your breathing in many ways. Cold air may dry out the throat and nose. This dryness can cause irritation and make you cough. Dust and dirt inside the AC filter can also cause problems. When these particles blow out, they may trigger allergies or asthma. Poorly cleaned AC units can spread germs and mold. These can cause cough, sneezing, and other symptoms.
Regular cleaning of filters helps keep air fresh and clean. Using a humidifier with AC can stop dryness. It is important to keep rooms well-ventilated. Fresh air helps reduce the risk of coughing from AC use.
