Human beings are thought to have evolved in close contact with wood and touching wood is known to have relaxing effects. In 10 health subjects participating workplace social gathering, the effects of the use of wooden tableware on autonomic functions and communication were examined in comparison to the use of porcelain-metal tableware with a crossover study design. Analysis of pulse rate variability revealed that, compared to porcelain-metal tableware, wooden tableware lowered the amplitude of low-frequency (LF, 0.04-0.15 Hz) component without affecting the amplitude of high-frequency (HF, 0.15-0.45 Hz) component, resulting lower LF-to-HF ratio. Communication measured by the total number of utterances did not differ with the type of tableware. Subjective evaluation by a post questionnaire also showed consistent results, indicating better impression, warmth, relaxation, remission, nostalgic feeling for wooden tableware than porcelain-metal tableware. The use of wooden tableware may reduce sympathetic tone at the workplace social gathering compared to porcelain-metal tableware.
