A person wearing any kind of mask faces breathing resistance as air filters through the device, making the wearer work harder to inhale than he would without the mask. This can have several adverse physiological effects when the mask is worn for long periods of time.

This delivers less oxygen into the body than when the person is not wearing a mask.
