Coronavirus: 'Deadly masks' claims debunked

Face coverings are now compulsory for customers in shops and supermarkets in England.

The mandatory wearing of coverings and masks has been polarising opinion for weeks, particularly in the United States.

The BBC's anti-disinformation team has been investigating false and misleading claims about the health risks of face masks and coverings being shared on social media.

Claim: Masks deprive your body of oxygen
Verdict: False claim

One of the most common themes in misleading posts surrounding the use of masks is that they limit the amount of oxygen getting into the body.

People have shared a graphic titled "danger of a face mask" and say this "may lead to death".

But the breathable materials recommended for face masks worn properly won't inhibit your breathing.

Breathlessness is a sign that your body is deprived of oxygen - known as hypoxia.

"Thin paper or cloth masks will not lead to hypoxia. Surgeons operate for hours wearing them. They don't get these problems," says Prof Keith Neal, an infectious disease expert.

The WHO says: "The prolonged use of medical masks when properly worn, does not cause CO2 intoxication nor oxygen deficiency.

"While wearing a medical mask, make sure it fits properly and that it is tight enough to allow you to breathe normally. Do not re-use a disposable mask and always change it as soon as it gets damp."

These oxygen-depleting claims have appeared in many different languages: English, German, Serbian and Hebrew Facebook posts alongside the same stock image of a toddler in a mask.

An article on a Nigerian news site, originally translated from Spanish, carried the claim back in April and has been shared 100,000 times.

Claim: Masks can cause carbon dioxide poisoning
Verdict: No evidence to support this claim

A post being widely shared on Facebook has lifted a medical diagram from Wikipedia showing the "symptoms of carbon dioxide toxicity".

The page, which has been shared many thousands of times, has then been re-edited to suggest a link to mask-wearing.

Two misleading graphics claiming face masks are dangerous

This modified version claims that wearing a mask leads to "re-breathing your exhaled CO2".

We've seen lots of posts alerting people to something called hypercapnia - where there's too much carbon dioxide in the blood.

"This simply won't happen unless there is an air-tight fit and you rebreathe your air," says Prof Neal.

Carbon dioxide molecules are tiny - far smaller than droplets containing coronavirus which the masks are designed to stop - and won't be trapped by a breathable material, particularly during relatively short periods like a bus journey.

When you breathe out, the carbon dioxide will go through and round the type of masks most commonly worn, and is unlikely to build up to the extent that it causes health issues.

Surgeons regularly wear much heavier-duty face coverings all day without coming to harm.

In the US, former professional baseball player Aubrey Huff vented his anger about being required to wear a mask, in a video which has been viewed over 1.6 million times.

He claims: "It's not healthy to breathe in your own CO2 all the time", but as we've explained there's no evidence that wearing a face covering causes this.

The World Health Organization (WHO) says face coverings should be worn to provide "a barrier for potentially infectious droplets" in areas where "physical distancing of at least one metre is not possible".

Home-made cloth face coverings can help reduce the spread from people who are contagious, but have no symptoms or are yet to develop symptoms.

Claim: Masks harm the immune system
Verdict: No evidence to support this claim

Another graphic shared thousands of times on social media includes several misleading claims, including one about the immune system.

It's called "What happens when you wear a face mask" and has been marked as containing false information on Instagram.

Misleading graphics claims face masks pose health risks including suppressing the body's immune system. Labelled no evidence.

Among the claims, it says that masks could "suppress" the body's immune system, leaving it open to infection.

But it's not explained exactly how or why masks are said to do this.

"Masks may stop germs getting into your mouth or nose so your immune system doesn't have to kick in, but this doesn't mean it is being suppressed," says Prof Neal.

It's worth pointing out that there are some situations in which face masks might not be advised:

  • children under two whose lungs haven't fully developed
  • people with respiratory conditions who may struggle to breathe
  • people should not wear masks when exercising

The Mask Mouth Story .. Sources like NY Post and Fox News of course are bias..
But the truth is and folks that Drink heavily , have Gingivitis and Gum Bacteria etc.. putting back on a mask causes hesitation.. and that is real
So Bad Breath and putting on a mask is an issue .. Sources aside

‘Mask mouth’ is a seriously stinky side effect of wearing masks

While mask mouth isn’t quite as obvious, if left untreated, the results could be equally harmful.
“Gum disease — or periodontal disease — will eventually lead to strokes and an increased risk of heart attacks,” says Dr. Marc Sclafani, another co-founder of One Manhattan Dental.

He says the stinky syndrome is triggered by face coverings, since wearing a mask increases dryness of the mouth — and a buildup of bad bacteria.

“People tend to breathe through their mouth instead of through their nose while wearing a mask,” says Sclafani. “The mouth breathing is causing the dry mouth, which leads to a decrease in saliva — and saliva is what fights the bacteria and cleanses your teeth.”

He adds that “saliva is also what neutralizes acid in the mouth and helps prevent tooth decay and gum disease.”
People’s tendency to drink less water while masked up, as well as consume more coffee and alcohol during lockdown, have also added to the widespread dehydration he’s seeing.
On the bright side, the dentists say that they’re packing in breath-conscious patients who might otherwise neglect their dental health during the pandemic.

“Patients are coming into us like, ‘Wow, my breath smells, I need a cleaning.’ [But] when you smell the bad breath, you either already have periodontal disease or you have a lot of bacteria that’s sitting on your tongue because of dry mouth,” says Sclafani.
While masks are not negotiable given the times, Sclafani says there are things wearers can do to avoid their grossest side effect: drink more water, cut down on caffeine, snag a humidifier (to “help moisten the air”), use an alcohol-free mouthwash, scrape your tongue and don’t smoke.
And If all else fails? “Just breathe through your nose!”

The face diaper IS a big hoax. A thorough course in Anatomy and Physiology taught me that WE INHALE 02 (OXYGEN) AND EXHALE C02 (CARBON DIOXIDE). Wearing a face diaper just recycles carbon dioxide, smh!

Thus, it is so important to have plants in the house to absorb the C02 that we exhale as well as foliage outside to absorb C02!
