According to a new study from researchers at MIT, indoor spaces lacking in humidity have the potential to increase COVID-19 transmission, since our breathing relies on a specific temperature and humidity ratio to block any viral pathogens as we inhale.
When air is inhaled, it is humidified in the trachea before traveling to the lungs. Then, hair-like appendages called cilia work to filter out pathogens and particles, and create mucus to help bolster that trapping process. When inhaled air is too dry, these protective measures are disrupted. | | Know More | | In order to reduce COVID-19 transmission, the study suggests the ideal range for relative humidity is between 40% and 60%. | | Feel Better | | Yes, a humidifier can help. But how will you know when a room is properly humidified? Consider buying a hygrometer, an inexpensive tool (roughly $10) that can tell you exact levels. But if you notice less static electricity and aren't bothered by dry eyes or skin as much, you're on the right track. | | |  | What Else Should You Know | | | 5 Ways to Avoid COVID-19 Misinformation | | Twitter will no longer be enforcing its policy against COVID-19 misinformation.
