| Research Abstract |
The purpose of this study was to clarify the effect of chewing efficiency on stress release. Increase in salivary cortisol was selected as an indicator of increase in stress. Evaluation of chewing efficiency was analyzed with a gluco sensor GS-1.As stress loading, subjects were required to perform arithmetic calculations. Next, they were asked to chew gum. Change in salivary cortisol levels immediately after stress loading and chewing was determined. The results showed that the number of chewing strokes effects on stress release greater than chewing efficiency.
