Is it safe to take them off when eating or drinking water?

No!. Same when you shower and sleep. I really hope you’re not showering and sleeping with your mask off. Piece of chit.



You better be driving with your windows down and mask on too!!!

That graph has to be one of the actually worst ways to present whatever data you are trying to say. Like what absolute dogchit scale, what terrible comparison choices, what terrible template and terrible scaling.


I mean holy fuk I don’t even think there’s a worse way to try and present this data, especially since a quick paragraph could probably be much more concise and provide much more relevant data that couldn’t be so easily misrepresented.


You should really feel bad for posting it.


And lmao even more so it’s 50 cherry picked flights with 4 categories so not even an equal split for the different categories?

These fuks literally just did search engine on news articles as their method lmfao


Seriously this is the bar for your fukking science now? You should be fukking ashamed.

I guess that depends on what you mean by safe. Removal opens the opportunity for infection.

There's accompanying text in the paper.

The paper is a systematic review.

Oh I dug in and elaborated.

Then when 300 people take their mask off to drink and eat their meals at the same time…….

Then when 300 people take their mask off to drink and eat their meals at the same time…….


Oh wait

Fauci enterprises thought of everything

That's the thing, like other PPE they only work when used

So no water, or food for an 8-10hr flight……

COVID-19: did the masks work?

"Face coverings, which cover the nose and mouth, are a means of preventing infections that travel in the air. These include viruses such as SARS-CoV-2, which causes COVID-19. Face coverings, or masks, played a key role during the COVID-19 pandemic by reducing person-to-person spread of the virus. The key features of a mask that make it effective are the material from which it is made and how closely the mask fits the face. A loosely fitting mask, for example, will lead to gaps around the nose and cheeks through which droplets can escape. A better fitting mask will have less leakage. Masks made from light single-layer material is less able to prevent droplet penetration than thicker, multi-layered fabric. Properly fashioned and fitted face masks are an effective means of slowing the spread of infections that travel in the air."

So it isn't safe to take the mask off when eating or drinking at a restaurant?

Now let’s do one on stunted learning and growth in the kindergartners and kids beginning elementary school.

Coming from a parent who’s been struggling bringing his dyslexic kid with speech issues up to speed. Thankfully being a good parent and working with his OT and school has let me somehow elevate my dislexic kid to a reading level above the national average of his peers.

But not above the national level of peers prior to Covid. It’s almost like the whole thing made an entire generation of kids stunted.


What are the dangers of a 6 year old being exposed to Covid again?

A 2006 study of 212 healthcare workers required to wear the medical-grade N95 face mask found that 37% said the mask gave them headaches, and 32% of those people had headaches more than six times a month. In a newer study at the National University Hospital in Singapore, 81% of medical personnel who wore the N95 mask for 6 hours a day developed headaches. 23% of participants said their headaches included migraine symptoms like nausea and photophobia.

Mask-wearers breathe in greater amounts of air that should have been expelled from their bodies and released out into the open. “[A] significant rise in carbon dioxide occurring while wearing a mask is scientifically proven in many studies,” write the German authors. “Fresh air has around 0.04% CO2,” they observe, while chronic exposure at CO2 levels of 0.3 percent is “toxic.” How much CO2 do mask-wearers breathe in? The authors write that “masks bear a possible chronic exposure to low level carbon dioxide of 1.41–3.2% CO2 of the inhaled air in reliable human experiments.”

In other words, while eight times the normal level of carbon dioxide is toxic, research suggests that mask-wearers (specifically those who wear masks for more than 5 minutes at a time) are breathing in 35 to 80 times normal levels

Can you share the reference for stunted learning due to mask use?

A ZOOM education was amazing for children……

I'd say that depends on what you mean by safe. How's the air quality in the restaurant? Are there infectious people in there? If so, how many? How large is the space?

Okay?

So restaurants aren't safe, let's shut them down for the good of society.

That seems extreme. But if you're uncomfortable, you could avoid them

“A total of 96 unique articles were identified, with 89 being from the search terms and 7 being from our snowball strategy. A total of 58 articles did not meet our inclusion criteria. We excluded 21 articles (4 regarding non-commercial aircrafts, 4 for SARS-CoV-2 modeling, 5 for medical details, and 8 for undetermined transmission). Retrospectively, we excluded two more articles for PCR pretesting before the flight. ”

So they omitted all the data that did not align with their narrative. Just lol

A new study suggests that the excess carbon dioxide breathed in by mask-wearers can have major health consequences.

Mask-wearers breathe in greater amounts of air that should have been expelled from their bodies and released out into the open. “[A] significant rise in carbon dioxide occurring while wearing a mask is scientifically proven in many studies,” write the German authors. “Fresh air has around 0.04% CO2,” they observe, while chronic exposure at CO2 levels of 0.3 percent is “toxic.” How much CO2 do mask-wearers breathe in? The authors write that “masks bear a possible chronic exposure to low level carbon dioxide of 1.41–3.2% CO2 of the inhaled air in reliable human experiments.

What can breathing too much carbon dioxide do to you? The authors write that “at levels between 0.05% and 0.5% CO2,” one might experience an “increased heart rate, increased blood pressure and overall increased circulation with the symptoms of headache, fatigue, difficulty concentrating, dizziness, rhinitis, and dry cough.” Rates above 0.5 percent can lead to “reduced cognitive performance, impaired decision-making and reduced speed of cognitive solutions.” Beyond 1 percent, “the harmful effects include respiratory acidosis, metabolic stress, increased blood flow and decreased exercise tolerance.” Again, mask-wearers are likely breathing in CO2 levels between 1.4 percent and 3.2 percent—well above any of these thresholds. What’s more, “Testes metabolism and cell respiration have been shown to be inhibited increasingly by rising levels of CO2.
So, high blood pressure, reduced thinking ability, respiratory problems, and reproductive concerns are among the many possible results of effectively poisoning oneself by breathing in too much carbon dioxide.

The authors write that “it is clear that carbon dioxide rebreathing, especially when using N95 masks, is above the 0.8% CO2 limit set by the US Navy to reduce the risk of stillbirths and birth defects on submarines with female personnel who may be pregnant.” In other words, mandates have forced pregnant women to wear masks resulting in levels of CO2 inhalation that would be prohibited if they were serving on a Navy submarine.

Indeed, according to the authors, there exists “circumstantial evidence that popular mask use may be related to current observations of a significant rise of 28% to 33% in stillbirths worldwide and a reduced verbal, motor, and overall cognitive performance of two full standard deviations in scores in children born during the pandemic.”

They cite recent data from Australia, which “shows that lockdown restrictions and other measures (including masks that have been mandatory in Australia), in the absence of high rates of COVID-19 disease, were associated with a significant increase in stillborn births.” Meantime, “no increased risk of stillbirths was observed in Sweden,” which famously defied the public-health cabal and went its own way in setting Covid policies."

No, I think like in most systematic reviews, these surgery followed their inclusion criteria.

Is over a year ago considered new?

Regardless, masks and respirators work

Masks work by effecting your health negatively, yes, they do not work at stopping viral transmission.

Sure seems like they do based on all the extant literature

Just lol @ dedicated anti maskers
