In March, the Hayride reported on the results of another mask study posted on June 10, 2020, at the CDC website. This study confirms our reporting from yesterday that masks aren’t just a nuisance but can cause serious health problems. The article recently uncovered was published by the CDC and it states in black and white the side-effects of wearing a mask, specifically related to the masks trapping carbon dioxide or CO2. The article states the masks cause breathing resistance that could result in a reduction in the frequency and depth of breathing, known as hypoventilation, in as little as an hour of wearing a mask.
