  • Many people suffer from colds or sniffles after using air conditioning.
  • A doctor explains the physiological reasons and offers remedies.
  • Proper ventilation and temperature regulation are key to prevention.

Air conditioning units, while providing welcome coolness, often lead to a common ailment: the common cold or sniffles. This phenomenon is familiar to many, prompting questions about its cause and prevention. Austrian newspaper Die Presse delves into this issue, consulting a medical professional to shed light on the physiological mechanisms at play.

The mucous membranes in the nose dry out.

— Dr. Martin SchabusDr. Schabus explains that the dry air produced by air conditioners is a primary reason for increased susceptibility to colds.

According to Dr. Martin Schabus, a specialist in ear, nose, and throat medicine, the primary culprit is the dry air produced by air conditioners. "The mucous membranes in the nose dry out," Schabus explains. This drying effect compromises the nose's natural defense system, making it more susceptible to viruses and bacteria. The cold air itself can also play a role by constricting blood vessels in the nasal lining, further impairing immune response.

Schabus emphasizes that the temperature difference is not the sole cause, contrary to popular belief. While a drastic temperature drop can weaken the body's defenses, the drying effect of the air is the more significant factor. He advises against excessively cold settings, recommending a maximum difference of five to seven degrees Celsius below the outside temperature. Maintaining a relative humidity of 40-60% is also crucial for optimal nasal function.

The temperature difference is not the only reason.

— Dr. Martin SchabusDr. Schabus clarifies that while temperature shock can play a role, the drying effect of the air is more significant in causing cold-like symptoms.

To combat the dreaded "air conditioning cold," Schabus suggests several preventive measures. Regular ventilation of rooms is paramount to ensure fresh air circulation and reduce the concentration of airborne pathogens. Using a humidifier can help counteract the drying effects of AC units, especially in arid climates or during prolonged use. He also recommends nasal sprays containing salt solutions to keep the mucous membranes moist and support their natural functions. Finally, he advises against direct exposure to the cold air stream from the AC unit, suggesting users adjust the airflow direction.

The maximum difference should be five to seven degrees Celsius below the outside temperature.
