Abstract: The hand plays a crucial role in our daily lives and affects the quality of life. Sensory stimuli can affect the activation of the autonomic nervous system to control body homeostasis and finger motions. This study aimed to determine the optimal thermal and auditory stimuli that affect hand dexterity. The experiment included thirty healthy adults. In the experiment, the thermal stimuli were classified into 20, 30, and 40 °C. The auditory stimuli were classified into fast- and slow-tempo music. Each stimulus was randomly provided for 5 min and hand dexterity was tested with the Groove and Purdue pegboard tests. After each stimulus and test was conducted, a resting time of 20 min was provided before the next stimulus. When the thermal stimulus of 30 °C and auditory stimulus of fast-tempo music was provided, the completion duration of the hand dexterity test was the shortest. Except the thermal stimulus of 20 °C, all thermal and auditory stimuli induced increased hand dexterity, compared to the non-stimulated condition. Among the five categories of thermal and auditory stimuli, the thermal stimulus of 30 °C and auditory stimulus of fast-tempo music were the most effective in improving hand dexterity.
