As temperatures rise, many of us rely on air conditioning and fans to keep cool. But could these cooling devices actually be making us sick? Experts reveal the truth behind the common belief that air conditioning and fans cause colds or infections.
Do Air Conditioners Spread Germs?
Contrary to popular belief, air conditioners don't directly cause colds. However, poorly maintained units can circulate dust, mould, and other allergens that may irritate your respiratory system. Dr Sarah Jarvis, a GP and clinical director, explains: "While cold air itself doesn't cause infections, dirty filters in AC units can spread airborne irritants."
The Fan Debate: Helpful or Harmful?
Fans are generally safer than air conditioners when it comes to respiratory health. "Fans simply move air around rather than recirculating it," says Dr Jarvis. "But they can dry out your nasal passages, making you more susceptible to viruses."
Tips for Healthy Cooling:
- Clean AC filters regularly
- Position fans to circulate fresh air
- Maintain moderate humidity levels
- Stay hydrated in air-conditioned spaces
Recognising the Real Culprits
If you're experiencing cold-like symptoms in summer, consider these more likely causes than your cooling devices:
- Summer cold viruses
- Allergies to pollen or dust
- Dehydration from heat
"The key is proper maintenance and sensible use of cooling devices," concludes Dr Jarvis. "Don't blame the technology when poor maintenance is usually the real issue."
