What research does and doesn’t tell us
There have been studies on whether beards accumulate, harbor or shed more or less bacteria than bare faces. But that research was inconclusive and on bacteria. There appears to be very little, 만약에 어떠한, research on whether beards accumulate, harbor or shed more or less virus than bare faces.
하나, given the evidence that “not being protected adequately with masks and social distancing does increase your risk of coronavirus,” Gohara said, “if your mask isn’t fitting properly, then you are increasing your risk.”
Health care workers often wear masks
, and they have known that facial hair is an impediment to proper mask-wearing since long before the pandemic
. What commonly reveals the problem is when medical professionals
’ fittings for N95 masks are unsuccessful because of facial hair
. Some facial hair styles aren’t recommended
, because they likely interfere with a respirator’s seal
(which presses to the face
), or because the hair might interfere with the exhalation valve
(which makes breathing easier

“For a mask to have any chance of fitting properly, it needs to be mask to skin, not mask to hair,” Gohara said.
“If a mask can completely cover a beard, there (하지 말아야) be any problem. If not, a beard is very likely to create a small gap between facial skin and mask unless one fastens the mask tightly,” said Qingyan Chen, a professor of mechanical engineering at Purdue University in Indiana, via email. “The small gap would create a leakage for air to enter (그만큼) nose when inhaling and for air with virus to go to the surroundings when one exhales.”
예를 들면, a gap
“of only 0.2-millimeter height can cause 2% ...에 8% of the inhaled air
(containing virus-transporting droplets
) to enter the mask unfiltered

, a post-doctoral researcher at Hamburg University of Technology in Germany

. The greater the gap

Why beards are tough to part with
Some people with beards may have worn the same style for years, finding their facial hair an important part of self-expression or image. Keeping a beard, 하나, isn’t always a matter of personal style or preference. Beards can be extensions of pillars of certain religious faiths, which might make the decision to shave them even harder.
Two doctors of the Sikh faith
, 예를 들면, sparked controversy by making a difficult call that would allow them to treat Covid-19 patients more safely
. They sacrificed Kesh
— the Sikh practice of allowing hair to grow to respect God’s creation
— by shaving off their beards to fulfill Seva
, service to mankind
Some followers of Islam, some sects of Judaism and Rastafarianism also have religious practices or cultural beliefs that prohibit cutting hair.
Skin issues can also be a factor in facial hair decisions
. Men of color
, particularly Black men
, are more likely to experience inflammation
, razor bumps and ingrown hairs after shaving
, Gohara said
. And the friction of masks against bare skin can cause irritation
, which can result in hyperpigmentation
, 그녀는 덧붙였다.
“Many infectious disease experts will say that if you can eliminate facial hair, or if you can at least trim it just so it fits within the confines of the mask, then that’s advisable,” Gohara said. “There have to be solutions for people where that’s not an option. And that’s something that, as medical providers, we need to address.”
How masks and facial hair can coexist
If completely shaving off your beard isn’t right for you, there are alternatives that may not compromise safety.
Trimming your beard or wearing a different style, like a goatee, is one option. Some online small businesses sell extra-large masks that fit over a beard and against one’s neck.
If you’re a medical professional
, you could request a controlled air purifying respirator or a powered air-purifying respirator
, which are designed to accommodate facial hair while protecting you and others
마지막으로, you could join the double-masking trend
, starting by wearing an N95 mask or masks with ties
“that kind of create a bit more security and tightness
,” Gohara said
. Follow up with another mask that you put over your beard
, fit snugly against your jaw or neck
, and secure by looping the straps behind your ears or by tying them behind your head
