ICU Doctor Runs 22 Miles With Mask On To Prove It's Fine For Oxygen Levels

Dr. Tom Lawton is an ICU doctor in the UK who has spent time treating COVID patients. He wanted to disprove online claims that wearing a mask drops your oxygen levels, and reassure people that wearing a mask to go indoors is perfectly safe.

So he ran 22 miles WITH A MASK ON, and checked his oxygen levels every 20-30 minutes. (Watch his video below)

According to FOX 13, Dr. Lawton said:

Wearing a mask the whole time, oxygen saturations are normal if they’re over 95% and mine were at 98% every single time I checked.
