81% of people feel happier during and after knitting.
physiotherapist Betsan Corkhill and Dr. Jill Riley performed a study of 3,500 knitters from 22 different countries in 2011.
Betsan is the pioneer of therapeutic knitting. Her work strongly suggests that the bilateral, cross midline, rhythmic repetitive, automatic nature of knitting movements attribute to a deep, meditative calm. In fact much of her success in gaining authority in the medical community has come from ceasing to refer to it as a craft, and instead as a form of bilateral rhythmic psychosocial intervention.
