Low Indoor Humidity Levels Cause Illness

Posted on January 24, 2017

During the winter, the indoor air can become more dry than usual, but did you know that this also causes the humidity levels to drop? A low indoor humidity level is an advocate for the spread of pathogens, such a flu and cold viruses.

Low indoor humidity levels can prolong the lifespan of bacteria floating in the air. In addition, the dryness caused by excessive heating causes mucous membranes in the nose and the lower respiratory system to dry out. Without these working properly, the body’s natural response to fight off airborne bacteria and viruses is weakened.

According to Nortec, a manufacturer of commercial and industrial humidification systems, humidity levels should not drop below 40%. Levels below such are prone to harmful viruses. They also noted that during a sneeze or cough, the aerosol droplets lose almost 90% of their weight due to water loss since they are being exposed to a much drier environment than normal. By losing this much of their weight, infectious salt concentrations are left lingering in the air. They can survive in the low humidity and travel significantly; where as in optimal humidity levels, the salt concentration decreases to a level most viruses cannot endure.

“Respiratory illness and disorders are among the top 3 reasons for work absenteeism due to illness,” proclaimed Nortec. Humidity testers are available online for purchase by anyone.
