FACT CHECK
Claim: Prolonged use of COVID-19-related face masks cause health problems due to breathing in too much exhaled carbon dioxide.
Rating: Mostly False
What's True: Breathing in excessive carbon dioxide is dangerous for the body. Some people with preexisting respiratory illnesses may face health issues only with prolonged use of tight-fitting masks, such as respirators.
What's False: However, people wearing cloth or surgical masks are in little to no danger of breathing in unhealthy amounts of carbon dioxide.
