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

Improper use of air conditioners can harm respiratory health. It may weaken the protective function of mucous membranes and cause irritation in the nose and throat. Some groups, such as the elderly, young children, and those with chronic conditions, face higher risks. Air conditioners do not spread viral infections like colds. However, misuse can lead to dryness, coughing, or a scratchy throat. In some cases, it may worsen symptoms of bronchial asthma.

Dirty filters can harbour dust and allergens, increasing health risks. To stay safe, users should avoid directing cold air at people and keep filters clean. Professional servicing is also advised.

Experts recommend maintaining indoor temperatures between 22–25°C in summer. The difference between indoor and outdoor temperatures should not exceed 5–8°C. Regularly airing rooms and keeping humidity at 40–60% can further reduce health risks. Proper air conditioner use helps prevent respiratory issues. Clean filters, moderate temperatures, and controlled humidity protect vulnerable groups. These steps ensure a healthier indoor environment during warm weather.
