The physiological and psychological effects of the expression and inhibition of emotion.

Previous work has indicated that humor enhances immunity, but the immunological effects of overt crying have not been studied. Thirty-nine women viewed sad and humorous videotapes and either inhibited or expressed overt expressions of laughter and weeping; these were observed and timed. Moods and immunity (S-IgA) were repeatedly measured. The humorous stimulus resulted in improved immunity, regardless of the overt laughter expressed; overt crying was immunosuppressive, whereas the inhibition of weeping in the context of the same sad stimulus was not. Moods were more negative following the sad stimulus and in the expression condition. The results with respect to humor are consistent with previous research; the immunosuppressive effect of overt crying is discussed in the context of various types of crying that may have different effects.
