Scientists' discovery: wearing a mask constantly has a side effect

Medical mask on the face reduces the physical performance of a person, experts from the University Hospital of Leipzig came to such conclusions.

During the experiment, the researchers used conventional surgical masks and FFP2 products with additional protection. To measure the performance of the participants in the experiment, the scientists asked them to put on masks and sit on a simulator (stationary analogue of a bicycle) or stand on a treadmill.

Twelve men passed the test without masks, then with surgical masks and filter masks. It turned out that medical devices negatively affect breathing, do not allow a person to draw enough air into the lungs and exhale quickly.

In addition, the subjects' blood acidity increased rapidly during exercise wearing masks, and the men themselves admitted that they felt discomfort. According to the director of the clinic and cardiologist Ulrich Laufs, the results of the study should be used to adjust the mode of wearing masks during a pandemic. If medical masks are prescribed to be worn by people involved in manual labor, they should be given more breaks.

The research results were published in Der Spiegel on July 20, 2020.
