Yoga and breathing exercises have a positive effect on children with attention deficit hyperactivity disorder (ADHD). After special classes, children improve their attention, decrease hyperactivity, they stay alert longer, and they can engage in complex activities longer. This is the conclusion reached by psychologists at Ural Federal University who studied the effect of exercise on functions associated with voluntary regulation and control in 16 children with ADHD aged six to seven years. The results of the study are published in the journal Biological Psychiatry.
