In the Yamagata study, individuals who laughed more than once a week had lower risk of cardiovascular disease and mortality.11 Similar results are available for persons with diabetes.12 Apart from end points such as cardiovascular disease, laughter also favourably influences softer end points like self - compassion13 and promotes resolution of hyperglycaemia.14 Results suggest that people with either type of diabetes are more inclined toward self-enhancing humour, less inclined toward aggressive humour, and score better on self-defeating humour.
