Is Air Conditioning Bad for You? Myths and Facts

For those feeling nervous about turning down the thermostat in summer can rest easier now.

New research finds that air conditioning saves lives and is less damaging than previously thought. (Plus more energy efficient cooling systems have been a game-changer and have less of an environmental impact than heating systems.) And there are things you can do to mitigate the effects of AC on your home’s air quality.

Here are some things you can do:

• Regular maintenance: Ensure your AC unit is regularly cleaned and maintained, including changing filters, to prevent the buildup and circulation of allergens and contaminants.

• Proper humidity levels: Use a humidifier if the air is too dry, and consider a dehumidifier if the air is excessively moist.

• Moderate temperatures: Avoid setting the AC to excessively low temperatures. A comfortable range for sleeping is typically between 60 and 67 degrees Fahrenheit (15.6 and 19.4 degrees Celsius).

• Ventilation: Open windows periodically to allow for fresh air circulation.

• Stay hydrated: Drink plenty of water to counteract the drying effects of AC.

• Avoid direct airflow: Position AC vents to avoid directing the cold air directly onto you, especially while sleeping.

• Consider air purifiers: Use air purifiers to remove airborne particles and improve indoor air quality.
