During exercise, with the increase of exercise time and range, the oxygen consumption of the body will also increase, but wearing a mask will lead to a decrease in oxygen intake, which will lead to a decrease in the oxygen binding capacity of hemoglobin, which will increase the blood supply burden of the heart over time and lead to insufficient blood supply to the heart and brain. Symptoms such as nausea, vomiting, blurred vision, headache, etc. may occur in light cases, and may endanger people's life safety and lead to sudden death in severe cases.
