The first two alleged effects on the list, hypoxemia and hypercapnia, have been debunked by fact-checkers.
A fact-check by USA Today found that mask wearing does not cause hypoxemia, a below-normal level of oxygen in the blood. PolitiFact rated False a claim that masks decrease oxygen intake.
Lead Stories and USA Today were among fact-checkers that found that hypercapnia — too much carbon dioxide in the blood — is not caused by mask wearing.
Dr. Amesh Adalja, a senior scholar at the Johns Hopkins Center for Health Security, said that although the article appears to be presenting a hypothesis, many of the effects it claims cite evidence related to N95 masks typically used by healthcare workers.
We’ve reported there are studies that show that medical N95 respirators may result in increased carbon dioxide, which can lead to headaches and fatigue.
PolitiFact has also rated False a claim that masks "will kill quite a few people, it’s well known that they reduce blood oxygen levels and those with respiratory and cardiac disorders will die."
And we rated False a claim that wearing face masks is more harmful to your health than going without one.
We tried to reach Vainshelboim by phone and email and did not receive a reply.
the stanford article is actually a paper submitted by one individual from november last year that's been thoroughly debunked
