Is a Mask That Covers the Mouth & Nose Free From Undesirable Side Effects in Everyday Use & Free of Potential Hazards?

Letter to the Editor of The Sun
by Paul Gilchrist  August 9, 2021

To the editor:

My letter in the July 24 Sun summarized research about CO2 inhalation by children wearing face masks. The research has generated controversy, as it challenges masking policies in many countries, including our own, but the only criticism I could find was from a Dr. Joseph Allen at Harvard who asserted it was a “fatal flaw” for the research not to recognize that most of the inhaled air is from outside the mask that mixes with the high-CO2 exhaled air held inside the mask. That criticism is erroneous. The report says exhaled CO2 collects inside the mask and “This carbon dioxide mixes with fresh air and elevates the carbon dioxide content of inhaled air...” The report doesn’t say air reaching the lungs has the extreme level of CO2 as the air trapped in the mask, only that it becomes unacceptably high.

Dr. Allen noted that research he’s done with professional-grade office workers found decreased decision-making ability at room CO2 of 1,400 ppm. He’s also found airline pilots in simulated performance tests failed urgent maneuvers at CO2 levels of 1,500-2,500 ppm. He noted school rooms typically have CO2 at 1,500 ppm or higher, yet he didn’t make the connection that inhaling ambient air with such CO2 levels known to negatively affect adults and mixing it with the extremely high levels of CO2 inside the masks is sure to have adverse effects on kids.

Unfortunately, research today may be censored if it’s not politically correct. JAMA’s editorial board has had turmoil since January due to unrelated CRT issues. Two editors have resigned, including the chief editor, who resigned on June 30. This mask research was reviewed, Ok'd, and published during his term, but his replacement quickly retracted it - apparently for political incorrectness. There's nothing wrong with the research itself.

A Crash Course on Face Masks

Masks are Harmful as Proven by Conway NH Parent.

"Aside from the possible oxygen and CO2 argument against masks, I would like to see a RCT or meta analysis showing their effectiveness in preventing spread of viruses. Also, as a speech-language pathologist, I can assure you they are contributing to learning challenges and deficits in children academically and socially."

"Carbon Dioxide's Effect on Your Brain -One 2012 study which assessed Carbon Dioxide and Decision-Making, showed that at 1,000 ppm CO2, performance in college students was reduced 12%. -At 2,500 ppm CO2, performance plummeted to 51% when compared to the control group at 600ppm! Classrooms often reach above 1,000 ppm. One study in Texas showed 21% of classrooms had CO2 concentrations over 3,000 ppm (4). THIS IS WITHOUT A MASK!!! He is at 4,000ppm after 1 min of normal, at rest breathing. He has tested at 10,000 ppm after 1 min sitting in a chair."

"He should have used an oximeter (measures oxygen levels) before and after his CO2 test to see if the person's oxygen level went down. That would be the true test."
