Humor's healing potential.
In the past three decades the medical world has begun to take more serious notice of the healing power of humor and the positive emotions associated with it. Humor and laughter are currently being employed by psychotherapists and other care givers as tools to promote and maintain health, as well as intervention and rehabilitation tools for a host of maladies and illnesses related to stress and life-style. Although this empirical medical approach is relatively new, the study of humor has revealed a complex psychological phenomenon. Senses of humor have been categorized in types associated with personality. Humor has many styles and can be found in almost any situation, on any occasion. Theories of humor include the superiority theory, the incongruity theory, the release/relief theory, and the divinity theory. Laughter has many clinical benefits, promoting beneficial physiological changes and an overall sense of well-being. Humor even has long-term effects that strengthen the effectiveness of the immune system. In healthcare, humor therapy can help relieve stress associated with disease and illness. It serves as a diversionary tactic, a therapeutic tool for disorders such as depression, and a coping mechanism. It also is a natural healing component for care givers trying to cope with the stress and personal demands of their occupations.
