A doctor from Dublin, Ireland, has proved that wearing a face mask does not lower oxygen levels by wearing 6 face masks at the same time.
Dr. Maitiu O Tuathail, a doctor from Dublin, filmed himself putting 6 masks on his face while recording his blood oxygen saturation levels.
In the video, he could be seen putting on mask after mask.
He then showed the oxygen level meter, which showed a healthy 98 to 99 percent of oxygen.
Dr. O Tuathail shared the video on Twitter and debunked the misconception that face masks affect oxygen levels.
He said that he was frequently asked by his patients about this after frequently seeing false information on several social media platforms.
Alongside the video, he said:
Getting asked, ‘Does wearing a face mask lower your oxygen levels’ repeatedly by patients today! Based on what they are reading on social media *Face coverings / masks don’t reduce your oxygen levels!* I managed to get six face masks on + it had no effect on my oxygen levels!
