(KMOX) - An ICU doctor from the United Kingdom recently grew tired of seeing false rumors being spread about wearing a face mask while working out. There were some saying a mask – meant to slow the spread of COVID-19 – would deplete your oxygen levels because it was blocking air from your nose and mouth.
Tom Lawton decided on a humid summer day to run nearly a full marathon to disprove that theory.
"I work in intensive care, I know physiology so I knew that this wasn’t true," he told CTV News. "So I thought how can I demonstrate it? How can I reassure people who would like to do their bit and wear a mask but are scared?"
He does understand some of the reasons why some refuse to wear a mask while working out.
"It’s certainly unpleasant and I feel for the people who don’t like wearing them, but this is one of the things that’s going to help us," Lawton says.
