AbstractAlthough laughter is a well-known method for alleviating stress, its stress reduction effects have rarely been quantitatively evaluated. The purpose of this study was to investigate laughter in everyday life and its effect on stress. A small, portable throat microphone that could automatically extract bursts of laughter was used to record the everyday laughter of five 20-year-old men. A salivary amylase monitor was to assess stress levels. As a result, frequent and infrequent laughter were found to be associated with a decrease and an increase in salivary amylase activity, respectively. From our results, increasing the occurrence of laughter, thus reducing the level of salivary amylase activity, may lead to health maintenance or health enhancement.
