Breathing difficulties with masks are mainly due to the fact that masks create a relatively confined space on people's faces. Therefore, part of the exhaust gas exhaled each time will remain in this space. When people inhale again, they have to breathe in this part of the exhaust gas first, thus reducing the amount of oxygen intake and causing breathing difficulties.

The mask will form a filter layer, and the outside air has to be filtered before it can be inhaled, which requires more force to meet the oxygen intake, so it is easy to have difficulty breathing.
