There has been much controversy surrounding the COVID-19  mask requirements for the past year.  Particularly given that Dr. Anthony Fauci and the World Health Organization (WHO) originally stated masks were not only unnecessary but potentially unhealthy,  only to reverse course.  This would be one of many examples of Dr. Fauci  contradicting himself, a more recent example during the first week of the Biden administration Fauci was pushing double masking. Only a short week later  Fauci backpedaled stating that there is no data that shows any benefit to double masking.   This after  the Biden administration has made it a federal crime to use public transportation without wearing a mask.

This type of rapid contradiction, often for political reasons, makes the the public question the validity of the science behind dealing with the COVID-19 pandemic. To say the least.

This is especially true when scientific publications going back decades have been thrown out because they go against the current narrative. One of the major concerns the public has is that of masks trapping carbon dioxide, downplayed and dismissed by the legacy media which even in their reporting had to acknowledge that the CDC admitted that masks do cause CO2 buildup over time 

Why the concern over Carbon Dioxide concentrations?  According to a 2016 Harvard Study, ambient Carbon Dioxide concentrations have been linked to cognitive decline. The human brains evolved in a period of lowered CO2 concentrations, ideally no more than 550 parts per million or PPM.  As little as 945 PPM lowers cognitive ability 15% and at 1400PPM of CO2 Cognitive Ability reduces by 50%.  While other countries such as Canada, Germany, Japan, Norway, Singapore, South Korea, and Taiwan consider 1,000 PPM of CO2 concentrations the highest acceptable level,  The US’ National Institute for Occupational Safety  and Health Administration or OSHA considers 5,000 PPM the highest acceptable limit for the United States, however many indoor environments including classrooms exceed that number.

Even moderate rebreathing Carbon Dioxide causes excessive CO2 buildup in the blood called hypercapnia and symptoms of discomfort, fatigue, dizziness, headache, muscular weakness, drowsiness and loss of productivity are  only the tip of the iceberg.  Masks only compound the CO2 concentrations in the blood

Numerous studies were released before the COVID-19 outbreak demonstrating masks and headgear do in fact trap carbon dioxide at considerable levels. 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.  These are the OSHA-violating conditions that are now present in typical working environments for someone in retail or an office environment requiring masks on a daily basis.  More recent studies also confirm that 60% of air exhaled is rebreathed while wearing a N95 mask.  This publication in the National Library of Medicine also states that masks do trap CO2 that can be rebreathed.
