Indoor Humidity Level Linked to COVID-19 Transmission

Published on November 17, 2022

Just like Goldilocks choosing the perfect porridge, finding the right humidity level indoors is crucial in battling COVID-19. A recent study from MIT has found that extreme levels of humidity, whether bone dry or sopping wet, can lead to worse outcomes for those infected with the virus. Similar to how temperature affects the behavior of gases, humidity affects the behavior of respiratory droplets carrying the virus. When it’s too dry, these droplets become lighter and stay suspended in the air longer, increasing the likelihood of transmission. Conversely, when it’s too humid, droplets grow heavier and fall to surfaces quicker, potentially contaminating commonly touched objects. This discovery underscores the importance of proper ventilation as a means to control the spread of COVID-19. By maintaining an optimal humidity level, we create an environment that is less favorable for the virus to thrive. Understanding this relationship between humidity and transmission can inform strategies for mitigating risk in indoor spaces. Get excited and dive into the MIT study for more fascinating insights!

A new study found that very dry or very humid indoor can worsen COVID-19 outcomes. Previous research has shown that proper ventilation can slow the spread of the virus, and now researchers at the Massachusetts Institute of Technology (MIT) have discovered that indoor…
