A doctor ran 22 miles with a face mask on to debunk a ridiculous myth

[Chris Smith]

• Wearing face masks is incredibly important during the coronavirus pandemic as the coverings can reduce the spread of the virus significantly.
• Some face mask protestors claim the use of face covers will reduce oxygen flow and cause hypoxia, a myth that can be easily debunked.
• A doctor ran 22 miles while wearing a face mask and monitored his blood oxygen saturation, which was normal throughout the effort.

Face mask protesters have made up several silly reasons to oppose the use of the simplest tool possible to reduce the risk of COVID-19 transmission. Some oppose the idea of being told what to do, suggesting face masks are about complying with the government. They are not. It’s about curbing the spread of the virus. Others claim the use of face masks is actually harmful, claiming they can reduce the flow of oxygen. That's also false. Again, the use of face covers can reduce the spread of a pathogen, protecting both the person wearing the mask and others.

A few weeks ago, a doctor put on six surgical masks at the same time to prove it wouldn't affect his breathing. He wore a pulse oximeter, a device that measures oxygen saturation, as proof. Unsurprisingly, the medical gadget confirmed his blood oxygen levels stayed within normal parameters. Another doctor performed an even more audacious task to dispel the hypoxia myth; he ran 22 miles and monitored his oxygen with the same type of device. The conclusion was identical: Face masks do not reduce the flow of oxygen, even if you’re running and need a much higher intake of air to supply the increased oxygen needs of the muscles.
