The people who wear a mask over their mouth only, leaving their nose uncovered. And maybe you wondered if that was OK. No, it’s not.
The SARS-CoV-2 virus lives in people’s nasal passages. When an infected person exhales, they release viral particles from their nose into the air. (And notice we’re talking about a basic exhale, not a cough or sneeze. Even the simple act of breathing releases particles.)
A mask — worn over the mouth and nose — helps to keep these infectious particles from becoming airborne and reaching others. If you want to buy disposable face masks online, you should refer to reliable online stores that not only offer best-quality masks but also assured your safety in this pandemic.
And wearing a mask (properly) isn’t just about protecting others. New research suggests that a mask reduces the volume of germs the wearer breathes in, protecting the wearer from getting sick.
So if you leave your nose uncovered, you’re breathing in more particles from the air around you, putting yourself at greater risk of catching COVID-19.
Some people claim they “don’t breathe through their nose” due to congestion or a deviated septum or another medical issue. This isn’t a pass to half-mask. Even if it feels like you can’t breathe through your nose, air is still moving through your nasal passages.
You still can breathe in viral particles or exhale them through your nose. So you still need a mask over your nose.
If covering both your nose and mouth with a mask makes you feel claustrophobic, try different types of face coverings — maybe a larger sized mask or a multi-layer gaiter — to find one that you can wear with reasonable comfort over your nose and mouth.
You’ll be keeping yourself safer from COVID-19 and also protecting others around you.
