Abstract:


To clarify the mental stress relief effects of wrist warming, we conducted an experiment involving 8 healthy participants and evaluated the differences in psychological and physiological responses between using a warm armrest and normal temperature armrest after mental workload from a timed typing test. Psychological responses were evaluated with a questionnaire: using 21 questionnaire items with 7 mood state categories: “Active”, “Anger”, “Comfort”, “Relaxed”, “Strained”, “Anxiety / Uneasiness”, and “Languor/Boredom”. Furthermore, physiological responses were evaluated with changes in the 3 following parameters: heart rate, skin temperature of the base of the little finger, and galvanic skin temperature. In this experiment, we used NeXus-10 MARKII for measurement and BioTrace+ for analysis. From our findings, when participants used the warm armrest after mental workload, their questionnaire scores of “Anxiety /Uneasiness” and “Comfort” were improved. In addition, we found that, in many of the participants, the skin temperature of the base of little finger was increased, although it was not in contact with the armrest. These results seem to suggest that wrist warming relieves mental stress.
