New research shows the risks from prolonged use of face masks
By Ugo Bardi and Harald Walach
There’s an old story about a guy who jumped into a thorn bush: He wanted to collect berries, but he failed to consider the adverse effects of the plan. Something similar happened with face masks during the COVID-19 pandemic: Masks were promoted, and often mandated, as necessary safeguards for reducing the chance of infection, while their possible adverse effects were brushed aside. While the science on the benefits of masking is still inconclusive, the latest research now shows that the prolonged use of face masks—especially those with tighter fits like the N95s—could harm wearers by exposing them to dangerously high levels of carbon dioxide.
The risks appear to be especially pronounced for young people. As part of a team of scientists, one of the authors of this article conducted a randomized study of the effects of masking on healthy school aged children in Germany. The results of this research, published in September 2022 in the peer reviewed journal Environmental Research, concluded that wearing masks raised the carbon dioxide (CO₂) “content in inhaled air quickly to a very high level in healthy children in a seated resting position that might be hazardous to children’s health.”
These results should not have come as a surprise. It has long been suspected that mask-wearing poses risks. In Germany, for instance, workers required to wear an N95/FFP2 respirator must get a certificate verifying their ability to do so, and even with said certificate, those workers are mandated to take a 30-minute break every 90 minutes. .........To Read More...
