No, it doesn't – unless you are a baby or a toddler.
Young kids and infants are only at risk because they could suffocate while wearing one. The same goes for anyone who has trouble removing a mask without help.
Others can wear face masks without risking their health, according to experts, despite false rumors to the contrary.
In areas where COVID-19 is spreading, health experts agree that wearing masks or other face coverings in public helps reduce the risk of spreading the virus when people can’t socially distance by staying 2 meters (6 feet) apart.
The coronavirus mainly spreads through droplets that are emitted when people talk, laugh, sing, cough and sneeze. Masks lower the likelihood of those droplets reaching other people. Even if you don’t have symptoms, you could be carrying the virus and could spread it.
When it’s humid outside, it could feel like it’s harder to breathe if you’re not used to wearing a mask, said Benjamin Neuman, a professor of biology at Texas A&M University-Texarkana. But he said masks don’t meaningfully decrease oxygen in the body.
“The body is quite good at adjusting to keep oxygen levels where they need to be,” he said.
There’s also no evidence that the use of masks causes fungal or bacterial infections, according to Davidson Hamer, an infectious disease expert at Boston University. Disposable face masks are meant to be used only once, then thrown in the garbage. With cloth masks, it’s a good idea to wash and dry them after each use.
Wearing a mask may be uncomfortable, but health officials say you should resist any urge to touch your face. That could bring germs from your hands into your nose, mouth, or eyes.
