From asthma to muscle tension: 5 health issues of prolonged AC usage
1/7
Air-conditioning risks
Air-conditioning is helpful in heat, but prolonged, poorly ventilated, or poorly maintained AC exposure can trigger dryness, respiratory irritation, and “sick building” symptoms. These alerts explain risks and easy fixes.
2/7
Dry skin and eyes
Cool, dehumidified air strips moisture from skin and tear film, leading to flaky skin, itchiness, and irritated, blurry eyes over long hours indoors; frequent short breaks, hydrating creams, and a humidifier help restore balance.
3/7
Dehydration and headaches
Low indoor humidity increases insensible water loss through breathing and skin, contributing to dehydration, headaches, and fatigue; keep water at hand, limit very low thermostat settings, and add electrolytes during long AC days.

4/7
Respiratory irritation and allergies
AC can worsen nasal dryness and carry dust, pollen, and dander when filters are dirty, aggravating rhinitis, asthma, or cough; change filters on schedule, vacuum regularly, and ventilate with fresh air windows or exhaust fans when feasible.
5/7
Sick building syndrome (SBS)
Spending long periods in under‑ventilated, air‑conditioned spaces correlates with nonspecific symptoms like headaches, dizziness, mental fatigue, and throat/eye irritation; improve airflow, maintain ducts, and schedule outdoor air exchanges to reduce SBS complaints.
6/7
Mold, microbes, and poor maintenance
Condensation and clogged filters can harbor mold and microbes that recirculate indoors, raising risks for sensitive lungs; clean drip pans, service coils and ducts, maintain proper drainage, and use HEPA-grade filtration where possible.
7/7
Temperature swings and muscle tension
Over‑cooling can cause muscle stiffness and thermal discomfort, especially when moving between hot outdoors and very cold rooms; aim for a moderate set point (around 24–26°C), dress in light layers, and avoid direct cold drafts on neck or back.
