| Research Abstract |
The purpose of this study was to clarify what effects laughter and happy experiences could have on the immune functions and QOL of the elderly under treatment. During the first stage, we conducted two experiments : the effects of karaoke [musical experience]. On the immune functions and the effects of watching a video comedy show on the immune functions of female college students, examining changes in the NK cells. The results showed that viewing a comedy show (positive fun) was related to a more significant increase of the NK cells than karaoke (active fun). Based on the results, we conducted the second stage using "live or video presentations of rakugo [comic monologue] and manzai [comic backchat]." We then examined the changes in the immune functions and QOL. The subjects were men and women of 70 years of age or above who were free of senility and staying in therapeutic units. Once a week, rakugo or manzai was presented and this was continued for 4 weeks. Before and after the presentation in the first and the fourth weeks, blood sample was taken and a questionnaire was administered. The first blood samples of 8 persons tested showed a significant increase in the following : NK cell activation (three subjects, 37.5%), the number of NK cells (six, 75%), β -endorphin (six, 75%), ACTH (six, 75%), and cortisol (seven, 87.5%). The last blood samples of 6 persons tested showed a significant increase in the following : NK cell activation (five, 83%), the number of NK cells (three, 50%), β-endorphin (four, 67%), ACTH (three, 50%), and cortisol (three, 50%). On the PGC Morale Scale and the Subjective Happiness Scale, three (50%) persons showed a significant increase over the first measurement. These results indicated that laughter and happy experiences exerted a somewhat positive effect on the immune functions and QOL.
