‘“The tiny movements kids make to stay balanced stimulates their brain and helps them focus” says Dr John Ratey, a professor at Harvard University. “Children with attention disorders have a sleepy cortex and exercise combats that mental disengagement. By using their core muscles, they’re flipping their cortex on and increasing their mental activity. The cerebellum part of their brain is really working to adjust, every millisecond”. Further evidence from WittFitt involving a research group of college students confirmed that they too felt more focused and actually preferred using the ball chairs to regular chairs.’
