Studies show a huge leap in Attention Deficit Hyperactivity Disorder (ADHD). Children with this disorder are extremely hyperactive and find it difficult to concentrate for even short periods. In the US, one in 18 school children now suffer from ADHD.
An extended hearty laughter improves blood circulation and flushes the lungs of stale residual air. It also releases dopamine, something most people with AD/HD don’t have enough of. Laughter helps to improve concentration power, increases learning ability and helps to enhance academic performance.
I’m interested to know what evidence there is in how laughter increases focus?
