Not only for relaxation but coloring the picture book is also believed to train motor skills and the brain in order to be more focused. Is that right? This is the opinion of a number of experts. In the early ’90s, doctors had studied the coloring effects for mental health. Psychiatrist Carl Jung as quoted by Fox News often provides coloring therapy to calm and make the minds of his patients more focused. Today, Carl’s technique is still recommended by doctors to deal with anxiety.
