The N95 disposable mask significantly increases breathing resistance, and wearing such a burden while exercising is likely to cause additional damage to a child's lung function. Strenuous exercise with a disposable mask is not recommended, as it may cause oxygen deprivation, and if your child needs to attend physical education classes, it is recommended to do so outdoors in a well-ventilated area. When engaging in sports activities, do not wear disposable masks and try to choose sports that can be played at a distance. S ource： https://www.unisourcesgroup.com/news/20.html
