The researchers found that when humidity is low, infection rates go up.
“When our nasal passages and those other sort of barriers get dried out, they’re not as intact. They’re not as able to prevent those viruses and bacteria from entering into our system,” Meade said.
Meade said people should stay hydrated, disinfect work surfaces frequently, wash their hands often, and keep their distance when people are coughing and sneezing.
And if people don’t have control of their work environment, Meade says a humidifier can help.
"I think it certainly can help from a symptomatic perspective, and it may decrease the risk of certain different types of viruses," Meade said.
