Breathing in excessive carbon dioxide is dangerous for the body. Some people with preexisting respiratory illnesses may face health issues only with prolonged use of tight-fitting masks, such as respirators.

“Dr. Dennis A Castro B” wrote in the Nigerian newspaper Vanguard, for instance, that prolonged use of face masks causes hypoxia: 

Breathing over and over exhaled air turns into carbon dioxide, which is why we feel dizzy.

This intoxicates the user and much more when he must move, carry out displacement actions. It causes discomfort, loss of reflexes and conscious thought. It generates great fatigue. In addition, oxygen deficiency causes glucose breakdown and endangered lactic acid rise.

Some people with pre-existing respiratory illnesses (like asthma, COPD), may face breathing difficulty with use of certain types of tight fitted masks, called respirators. [There is] less chance of hypoxia as they may discontinue using masks in that case. Risk is very low with cloth and surgical masks as they are not tight around [the] face
