How dangerous is it to wear a high-performance mask for vigorous exercise? In a recent experiment, South Korean researchers asked a man in his 20s to walk slowly on a treadmill at a speed of 3 kilometers per hour, then increased the speed to 6 kilometers per hour, and then measured the number of heartbeats, blood pressure, and oxygen saturation.
Men then carried the same movement and measured the data with high-performance masks that blocked 90% of fine particles.
Experiments showed that the differences in data were not great when walking slowly, but when walking accelerated, his systolic pressure rose from 124mmHg to 141mmHg and the oxygen saturation of arterial blood dropped from 96% to 95%.
Due to the protective compensation reaction of the human body, wearing high-performance masks in daily life will not be abnormal.
But if you exercise vigorously, even healthy people can lead to body replacement disorders, increasing the burden on the lungs and heart, and the risk is greater if the exercise causes the mask to be soaked with sweat.
Professor Yan Zhenhe, department of preventive medicine at Yonsei University School of Medicine in South Korea, said that when masks are soaked, people’s breathing capacity decreases by 10 to 20 percent, meaning that heart and lung function can only function by 60 to 70 percent.
Experts recommend that it is best not to wear a mask when exercising vigorously, pay attention to keep ingress, or wear a common mask that is easy to breathe.
