A group of researchers in Ohio did tests on adults with an average age of 33 years old. Almost a third of them had a health condition like asthma. The researchers did 10 minute tests of no mask while walking and sitting, a cloth mask while walking a sitting, and a surgical mask while walking and sitting. The studies showed that no one had a low level of oxygen or a high level of carbon dioxide in the blood.
One doctor called Dr. Steven Shain who was also the main investigator in this test said that the risk of developing a low level of oxygen or a high level of carbon dioxide with a mask on is “near zero for the general population.”
