If there was one downside to it all, then it was that she was unable to take off her mouth mask the whole time when around them.
It could make it a little more difficult to breathe with the mouth mask being over her mouth and nose like that, even if it was not on too tightly.
She could still perform her chants and everything else, but it did make breathing a little more difficult, especially during times when she was having to overexert herself, resulting in her breathing a lot faster and heavier.
Wearing a mask while running or exercising could result in increased resistance to airflow, making it harder to inhale the necessary amount of air during exercise, which could lead to a decrease in oxygen intake and increased carbon dioxide levels in the body.
Another existing problem was that it could cause carbon dioxide to be trapped, which could simulate the effects of high altitude training and could be problematic for individuals with underlying health issues.
