The Harm Caused by Masks
-
Evidence continues to mount that mask mandates were perhaps the worst public-health intervention in modern American history. While concluding that wearing masks “probably makes little or no difference” in preventing the spread of viruses, a recent Cochrane review also emphasized that “more attention should be paid to describing and quantifying the harms” that may come from wearing masks. A new study from Germany does just that, and it suggests that the excess carbon dioxide breathed in by mask-wearers may have substantial ill-effects on their health—and, in the case of pregnant women, their unborn children’s.
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.
The German study, a scoping review of existing research, aimed “to investigate the toxicological effects of face masks in terms of CO2 rebreathing on developing life, specifically for pregnant women, children, and adolescents.” The latter two groups, of course, have been among those most frequently subjected to mask mandates in schools, despite Covid’s low levels of risk for them and the evidence that masks don’t work.
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.
Sorry, I'm calling BS on this one. In my extensive study of a series of one, someone who has worn a mask for up to 10 hours at a time, I really, really question these results.

It is certain that one breathes in more carbon dioxide when wearing a mask. The much giggled at "I can't breathe", is hyperbolic but with some truth. Some people seem not to notice. I recall when I was a kid, I saw siblings or friends cover their whole body and head in a blanket and just stayed like that for a long time. I would try it and I felt like I couldn't breathe. I despised wearing a mask for this reason. It made me uncomfortable and I felt like I couldn't breathe (as well as normal).
Whether that has any effects beyond discomfort, I don't know.

Edit: Sorry - I wasn't trying to make light of Jon's previous situation. He had to go and post something serious while I was still writing!
