Face masks may raise the risk of stillbirths, testicular dysfunction and cognitive decline in children, ‘explosive’ new research suggests. A review of dozens of studies on face coverings suggested they can cause mild carbon dioxide poisoning when worn over long periods. The German research team gathered data from 43 previously published studies on exposure to CO2, mask-wearing and pregnancy. They found 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. One mask study conducted in Germany, researchers measured the CO2 concentration of air behind surgical masks worn by 15 healthy men. Within 30 minutes, the CO2 concentration rose to roughly 2.8-3.2 percent. The gas makes up around 0.04 percent of all inhaled air, for comparison, and the Department of Agriculture said safe levels should be below 0.5 percent for eight-hour exposure. https://www.technocracy.news/face-mask-risk-stillbirths-testicular-dysfunction-cognitive-decline/
