Many UAE residents notice the same thing every summer — dry throat, blocked nose, headaches, and tired eyes after spending hours indoors. Doctors say air conditioning does not directly make you sick, but the environment it creates can. When filters are dirty, air is too cold, or ventilation is poor, the body starts to react. Dust, mould, trapped allergens, and sudden temperature changes between the hot outdoors and freezing indoors all add up over time and wear the body down gradually.
Sick Building Syndrome Is More Common Than You Think
There is actually a medical name for what many office workers and residents experience — sick building syndrome. The symptoms include persistent headaches, blocked nose, dry cough, dizziness, skin irritation, and brain fog that gets worse the longer you stay indoors. Many people feel better almost immediately after stepping outside. Doctors across the UAE say they regularly see patients during summer months with these exact complaints, especially those spending long hours in sealed, heavily air-conditioned spaces.
Dirty Filters Are the Biggest Culprit
Experts recommend cleaning AC filters at least once a month during heavy use. When filters are not cleaned, they trap bacteria, dust mites, mould spores, and pollen — then blow them straight back into the room. People with asthma, allergies, or sinus problems are most at risk. During summer holidays, many families switch their AC off completely for weeks. When they return and switch it back on, the system can push out weeks of built-up dust and allergens all at once, causing immediate irritation.
Keep Temperature Between 21°C and 24°C
Doctors advise keeping your AC set between 21°C and 24°C — not lower. Every degree below 24°C raises your electricity bill by six to nine percent and makes the air drier and harder on your body. Avoid sitting directly under cold airflow and drink plenty of water throughout the day. During vacations, set your AC to 25°C or 26°C on dry mode rather than switching it off completely — this keeps humidity under control and stops mould from building up inside the unit.
