Air Conditioning and Sick Building Syndrome Alert

Heat relief from cooling can come with hidden health risks when maintenance falls behind, experts warn.

Air Conditioning and Sick Building Syndrome Prompt Health Warnings

Air conditioning eases heat and humidity, but health experts warn it can also contribute to sick building syndrome when systems are poorly maintained. The NHS describes the syndrome as a cluster of symptoms that appear in a building and tend to worsen with time inside, easing after leaving. A 2023 Indian study followed 200 office workers in AC environments and found they reported more symptoms, reduced lung function and more missed days than those not in AC, suggesting prolonged exposure may be linked to health effects.

Experts emphasise that poorly maintained systems can release allergens, chemicals and microbes. Legionella bacteria, fungi and even viruses can thrive in damp, dirty ducts. The advice is clear: regular maintenance and sanitisation reduce risk, and workers should involve building managers and health authorities if symptoms appear. While AC can spread illness in some conditions, it can also help stop disease spread when properly cleaned and filtered, the article notes.

The piece highlights a tricky balance between comfort and health in modern offices. Cooling systems offer relief but also create a pathway for illness if filtration, humidity control and water systems are neglected. This framing invites readers to see indoor air as a health issue rather than a mere convenience.

For workplaces, the takeaway is practical: audit systems, upgrade filtration where needed, test for Legionella and ensure regular cleaning routines. Clear communication with staff about symptoms and maintenance plans is essential to prevent fears from turning into real harm. The article also raises questions about how health guidance is conveyed so people stay informed without panic or complacency.
