The researchers reviewed 43 previously published studies on face mask to find if it creates a pocket of dead space between itself and the mouth that traps the toxic gas. They said that after wearing a mask for more than five minutes, CO2 levels in the inhaled air rose to between 1.4 percent and 3.2 percent. The research team also cited that the build-up of CO2 in pregnant women's bodies could cause complications for the unborn fetus. Carbon dioxide is known to contribute to oxidative stress, which the researchers suggested would hinder fetal development.
"Circumstantial evidence exists that popular mask use may be related to current observations of a significant rise of 28 percent to 33 percent in stillbirths worldwide," the team said in the review and cited the surge in stillbirths during the Wuhan coronavirus (COVID-19) pandemic when the mask mandate was among the first public health responses to mitigate the virus.
The researchers also noted that the extensive use of face masks may have contributed to the "reduced verbal, motor and overall cognitive performance of two full standard deviations in scores in children born during the pandemic."
According to National Institute for Occupational Safety and Health (NIOSH), there is a meager 0.5 percent threshold limit for carbon dioxide concentration inhalation across a period of eight hours. Unfortunately, the researchers found that nearly every study they looked into showed that masks exceeds the 0.5 percent CO2 concentration standard.
The review also included a study which found that just 0.3 percent prolonged CO2 exposure to both pregnant rats and young mice led to brain damage, heightened anxiety and poorer memory. Another found that male mice exposed to 2.5 percent CO2 for four hours, which is equal to 0.5 percent for humans, resulted in the destruction of testicular cells and sperm.

Back in January, a Cochrane review deemed that wearing masks in the community probably makes little or no difference to the outcome of influenza-like illness compared to not wearing masks. The review also indicated that the use of an N95/P2 respirator compared to medical/surgical masks probably makes little or no difference in the outcome of laboratory-confirmed influenza infection.
These claims were made with "moderate certainty," the second highest of four certainty classifications. Medical journals say that Cochrane reviews are recognized worldwide as the highest standard in evidence-based healthcare; are the best single source of highest-quality systematic reviews; and are regarded as the final word in the medical debate on a topic.
According to the said review, face coverings do not have a significant relationship to the suppression of pulmonary viruses and may instead spread them. The review suggested the possibilities of "self-contamination of the mask by hands" and "saturation of masks with saliva from extended use (promoting virus survival in proteinaceous material)."
Back in March 2020, then-Surgeon General Jerome Adams said: "Folks who don't know how to wear [masks] properly tend to touch their faces a lot and actually can increase the spread of coronavirus."
Meanwhile, one randomized controlled trial has found that "the virus may survive on the surface of the facemasks and transfer pathogen from the mask to the bare hands of the wearer."
