Ageing can be associated with physical, cognitive and/or social loss. Most older people, however, cope well with this loss, perhaps by using humour. In this review the research findings concerning humour were collected. Twenty six relevant publications were found. The sense of humour does not seem to be greater in older than in younger adults. There are no indications that humour appreciation or production is associated with longevity. In older people there is a correlation between humour on the one hand and well-being and morale on the other. It has not been proven, however, that the use of humour by the elderly people has a favourable influence on their health. In health care for older people humour is sometimes used as a therapy. Scientific evidence of any positive effects of humour on mental health was not found. It is perhaps better for caretakers to show appreciation for the humour of older people than to make jokes about older people oneself.
