During the COVID-19 Pandemic, face mask wearing became mandatory.
As stated before, 940 PPM of carbon dioxide in a room reduces cognitive ability by 15%, 1,400 PPM reduces Cognitive Ability by 50% . This CDC publication from 1998, states surgical masks increase CO2 concentrations breathed in up to 5000PPM! at 8 hours in a room that only had a baseline of 450 PPM of CO2. https://www.cdc.gov/niosh/nioshtic-2/20044074.html CDC even admitted in 2020 that CO2 builds up wearing a mask for several hours

This twitter video seems to demonstrate this causing gas concentrations to linger around the wearers hear instead of dispersing. https://twitter.com/MarkDice/status/1312810470449979392?s=09 Some have speculated this could lead to many liability claims down the road. https://alachuachronicle.com/human-factors-expert-masks-may-increase-business-liability/ and https://alachuachronicle.com/letter-neurosurgeon-details-risks-of-face-masks/
This video using an OSHA approved Carbon Dioxide meter shows the rapid increase of CO2 inhalation to unhealthy levels. https://www.bitchute.com/video/cBR0zTOh0bLV/

This study published in the National Library of Medicine also confirms that masks can cause significant rebreathing of carbon dioxide. https://pubmed.ncbi.nlm.nih.gov/23514282/
Ben Swann even stated on the air that peer-reviewed studies about the ineffectiveness of masks along with the potential health side effects have been actively scrubbed off the internet because it goes against the narrative. https://www.bitchute.com/video/XWucehEiyToe/
16 minutes in the presentation of Spinal Surgeon Dr. Lee Merritt, she states that it is confirmed that facemasks do in fact build up carbon dioxide concentrations leading to cognitive decline. https://banned.video/watch?id=5f9f56fcf2aba40f0a83d61d

There are literally thousands of preventable surgical mistakes every. https://www.webmd.com/a-to-z-guides/news/20121220/thousands-mistakes-surgery#1 Makes you question if the reason for these mistakes is because of the cognitive decline of the surgeon while wearing a mask.
Even Senator Rand Paul MD says masks are not effective in preventing or even slowing the spread of Covid-19 https://banned.video/watch?id=6012c9eae79e01123a063c07

Cognitive Assessments taken while being forced to wear a mask for several hours trapping CO2 will lead to an artificially bad cognitive score, which is used against the pilot mandated by the FAA to take the test in order to retain their FAA medical certification.
psychologists have even weaponized not going along with COVID protocols claiming those that those that don't social distance have deficient working memory. https://www.psypost.org/2020/07/study-lower-cognitive-ability-linked-to-non-compliance-with-social-distancing-guidelines-during-the-coronavirus-outbreak-57293 and https://www.miamiherald.com/news/coronavirus/article244254847.html and https://www.sciencedaily.com/releases/2020/07/200710212241.htm They claim deficient working memory is a sign of being mentally defective.
According to the Wikipedia definition Nonetheless, Cowan proposed that working memory has a capacity of about four chunks in young adults (and fewer in children and old adults). Whereas most adults can repeat about seven digits in correct order, some individuals have shown impressive enlargements of their digit span—up to 80 digits. As in it's tiny and that's not a trait of being mentally defective https://en.wikipedia.org/wiki/Working_memory#:~:text=Nonetheless%2C%20Cowan%20proposed%20that%20working,span%E2%80%94up%20to%2080%20digits. Most adults can on average only repeat 7 digits in the CORRECT OR, and not backwards as required by the cogscreen. it only lasts 30 seconds https://www.verywellmind.com/what-is-short-term-memory-2795348
Working member is also negatively affected by CO2 https://www.weforum.org/agenda/2018/12/increased-levels-of-carbon-dioxide-could-reduce-brainpower-study-finds/ So a cognitive test taken while wearing a mask which traps CO2 will result in cognitive results and working memory results that are artificially lower than reality.
Washington Post reports that CO2 detectors were used to deremine if people were social distancing. The argurment is for mask use is to trap the breath and virus spread close to the person breathing out, which with would include CO2. https://www.washingtonpost.com/health/2021/02/10/carbon-dioxide-device-coronavirus/
This study concludes CO2 of PPM mask wearers is 2875 PPM or twice the 1400 PPM that the Harvard study stated cause 50% cognitive loss. https://aaqr.org/articles/aaqr-20-07-covid-0403
This study admits masks do trap CO2, but claim it's below 5000 PPM so it's not harmful. The title is wrong anything above 940PPM is harmful and a safe level really should be no higher than 450 PPM of CO2 Study

Study was also published in the NIH https://pubmed.ncbi.nlm.nih.gov/33858372/
This study shows not wearing a mask CO2 concentrations range from 500-900 PPM. wearing a mask CO2 concentrations rise to 2200-2875 PPM well over the 1400PPM threshold of 50% cognitive loss https://publications.jrc.ec.europa.eu/repository/handle/JRC121131
2013 from the University of Wollongong Australia shows CO2 levels increase dramatically wearing facemasks https://ro.uow.edu.au/cgi/viewcontent.cgi?article=1836&context=smhpapers
Harvard Medical School even published N95 masks cause CO2 increases https://www.atsjournals.org/doi/pdf/10.1513/AnnalsATS.202007-812RL

Medical Engineering and Physics Volume 98 Dec 2021 states CO2 blood concentrations increase while wearing a mask while exercising https://www.sciencedirect.com/science/article/pii/S1350453321001223
NIH publication from April 2021 states decreased oxygen saturation and increased CO2 concentration. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8072811/
August 2021 publication states that N95 masks trap excessive amounts of CO2 with the first breath accounting for a 555% increase https://aip.scitation.org/doi/10.1063/5.0061574
N95 masks cause 7x rebreathing of CO2 compared to not wearing a mask. https://pubs.aip.org/aip/pof/article/33/8/081913/1064899/N95-respirator-mask-breathing-leads-to-excessive
2023 entry in the NIH states that extended mask wearing causing CO2 toxicity of chronic mask wearing https://pubmed.ncbi.nlm.nih.gov/37057051/
2023 NIH publication MRI results show masks trap CO2 cause hypoxia in cortex. The Conclusion states, The results showed that wearing KN95 masks could change spontaneous neural activity and the functional connectivity patterns in the brain. These results suggest that people who need to wear masks in their daily work should appropriately increase the rest time or shorten the work cycle. If the rest conditions cannot be met, it is recommended to wear forced ventilation masks to avoid any problems caused by changes in brain function. That rest does not happen durring a cognitive test, quite the opposite exacerbating the damage. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10237040/
Even this 2021 publication in the NIH that tries to downplay the effects of the mask admits reduced oxygen intake and increaesed CO2 intake do to rebreithing of expelled air trapped in the mask. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8522266/
