Relative Humidity & Airborne Viruses

Winter is upon us and cold temperatures are forcing us to retreat inside for warmth. Unfortunately, as we increase the temperature on our thermostat, we also remove moisture from the indoor air, thus lowering our home’s relative humidity (RH). This lowered humidity does more than create comfort issues — it can also create health problems.

This dry indoor air can leave our skin and lips feeling chapped, cause bloody noses and sore throats, and result in an increase in static shocks. More importantly, dry indoor air increases the transmission rate of airborne viruses like the flu and COVID-19.

Dr. Stephanie Taylor, Infection Control Consultant at Harvard Medical School and member of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Epidemic Task Force said, “Our natural defenses are quickly impaired at RH 20%, resulting in increased susceptibility to respiratory infections such as COVID-19.”

Keep Your Home’s Relative Humidity Between 30-60%

ASHRAE and the Centers for Disease Control and Prevention (CDC) recommend keeping your home’s relative humidity between 30-60%.

Dr. Walter Hugentobler, University of Zürich, adds, “Humidification gives people a simple means of actively combating seasonal respiratory infections, including the fearsome SARS-CoV-2 virus.”
