* A German study reported the responses of parents of 25,930 children on the adverse effects from mask wearing.
Impairments caused by mask-wearing included irritability (60%), headache (53%), difficulty concentrating (50%), less happiness (49%), reluctance to go to school/kindergarten (44%), malaise (42%) impaired learning (38%) and drowsiness or fatigue (37%). This suggests that the wearing of face masks does not allow children to be at their best to learn.
