If you have difficulty breathing while wearing a mask, you can try to reduce the time you wear the mask or choose a mask with a higher comfort level. There are some non-woven masks or cup type masks with good airtightness that may cause breathing difficulties and lack of oxygen, so try to reduce the time of wearing the mask. Some people have bronchial asthma, chronic obstructive pulmonary disease (COPD) or other respiratory diseases, which may cause lack of oxygen and difficulty in breathing when wearing masks. It is better to isolate the patient at home and go out as little as possible to avoid this situation.
