Can Too Much Air Conditioning Harm Your Health?

Air conditioning has become essential for many people during Bangladesh's intense heat, but prolonged exposure to heavily cooled indoor environments can also affect health if not used properly.

Air conditioners work by removing heat and moisture from the air, creating a cooler environment. However, the resulting low humidity can dry out the eyes, nose, throat, and skin, while also aggravating conditions such as eczema, allergies, and sinus irritation.

Extended time in air-conditioned spaces may also contribute to headaches, fatigue, and dizziness. Experts say this is often linked to dehydration, as people tend to drink less water in cooler environments despite continuing to lose fluids.

People with asthma or other respiratory conditions may experience additional discomfort, particularly if air-conditioning systems are poorly maintained. Dirty filters can circulate dust, allergens, and mould-related irritants, while dry indoor air may trigger sore throats, coughing, and sinus problems.

Health experts also point to the frequent transition between hot outdoor temperatures and very cold indoor spaces as another factor that can leave people feeling sluggish and place added stress on the body.

They recommend keeping indoor temperatures comfortably cool rather than excessively cold, staying well hydrated, regularly cleaning AC filters, and ensuring proper ventilation. Using moisturisers or artificial tears may also help relieve dryness caused by prolonged exposure to air-conditioned environments.

Experts say air conditioning remains an effective way to stay safe during extreme heat, but proper use and regular maintenance are key to avoiding its unwanted side effects.
