| Outline of Final Research Achievements |
The effects of gum chewing varies with components of gum. In this study, the effects of chewing of gum containing capsaicin, which is a novel ingredient for gum and a pungent stimulation, were investigated by measuring salivary secretion, autonomic nervous activities and electroencephalogram (EEG). Chewing of capsaicin-containing gum induced higher and more persistent increase in salivary flow compared with tasteless gum and base (sweet) gum. It caused a decrease in parasympathetic activity accompanied with an increase in sympathetic activity and an increase in ratio of beta wave component in EEG, which were also observed during chewing of other gums. In addition, chewing of capsaicin-containing gum during calculation task of Kraepelin test prevented a decrease of answer rate over time, suggesting an effectiveness for improvement of work efficiency through arousal effect.
