How Your Air Conditioner Could Be Harming Your Health Without You Knowing

Air conditioners can improve comfort in hot weather but require careful use. Dirty filters and poor maintenance may harm health, particularly for vulnerable groups. Experts advise following specific guidelines to stay safe and healthy. Dirty air conditioner filters can collect dust and allergens. Cleaning them every two to four weeks helps prevent these issues. Professional servicing once or twice a year also ensures proper function.

Improper use can dry out nasal and throat passages, causing irritation or coughing. It may also worsen symptoms for those with bronchial asthma or allergic rhinitis. Sudden temperature drops and cold airflow directed at people can stress the body and weaken its defences.

The ideal indoor temperature in summer is between 22–25°C. The difference between outdoor and indoor temperatures should stay within 5–8°C. Humidity levels of 40–60% are recommended for comfort. Avoid pointing cold air directly at individuals, especially while they sleep or work. Certain groups, including young children, the elderly, and those with chronic respiratory conditions, must take extra care. They should avoid direct cold airflow and keep units well-maintained. Anyone experiencing coughing, shortness of breath, or worsening allergies should consult a doctor.
