Air-Conditioned Spaces Offer Heat Relief, but Fresh Air Still Matters

Air-conditioned rooms and offices can offer welcome relief from rising temperatures. But spending long hours in enclosed spaces may come with health drawbacks, particularly when ventilation and maintenance are poor.

Cooling a room does not necessarily bring fresh air into it. In poorly ventilated spaces, indoor pollutants can build up, while sharing enclosed rooms with others can increase exposure to respiratory infections.

Air conditioning can also reduce indoor humidity, contributing to dry eyes, irritated throats and dry skin. People with allergies or asthma may be sensitive to dust or mould circulating from poorly maintained systems.

To reduce these risks, keep cooling systems clean and maintain filters according to the manufacturer’s instructions. Allow fresh air in when outdoor temperatures and air quality permit, and avoid directing cold airflow straight at your face or body.

Drinking water regularly and taking breaks from prolonged sitting can help keep indoor routines healthier. Anyone experiencing persistent breathing difficulties or irritation should seek medical advice rather than assume air conditioning is the only cause.
