Psychological and physiological effects of sole contact with oil-finished wood
In Japanese households, it is customary to walk barefoot on wooden floors. Previous reports on the psychological and physiological relaxing effects of feet contact with uncoated solid wood have already been published. However, there are no studies on the effects of feet contact with coated wood, which is commonly used for residential floors. This study aimed to validate the psychological and physiological relaxing effects of sole contact with oil-finished wood. In total, 27 women university students (mean age: 21.9 ± 1.9 years) participated in this study. Psychological indices such as the modified semantic differential method and the Profile of Mood States Second Edition were used. The oxyhemoglobin (oxy-Hb) concentrations in the prefrontal cortex were determined using near-infrared time-resolved spectroscopy. The sympathetic nervous activity and the parasympathetic nervous activity were measured using heart rate variability. The flat plate for tactile stimulation was oil-finished wood, and uncoated wood and marble were used for comparison. The sole of the feet of each participant touched each material for 90 s. Feet contact with oil-finished and uncoated wood had relaxing effects on psychological and physiological responses compared with marble. The relaxing effects of oil-finished wood and uncoated wood were similar. That is, they significantly increased subjective feelings of comfort and relaxation, improved mood states, and decreased oxy-Hb concentration in the left prefrontal cortex compared with marble. However, there were no statistically significant differences in terms of right prefrontal cortex and sympathetic nervous activities between oil-finished wood and marble. Oil-finished wood had a slightly weaker physiological relaxation effect than uncoated wood.
期刊介绍:
The Journal of Wood Science is the official journal of the Japan Wood Research Society. This journal provides an international forum for the exchange of knowledge and the discussion of current issues in wood and its utilization. The journal publishes original articles on basic and applied research dealing with the science, technology, and engineering of wood, wood components, wood and wood-based products, and wood constructions. Articles concerned with pulp and paper, fiber resources from non-woody plants, wood-inhabiting insects and fungi, wood biomass, and environmental and ecological issues in forest products are also included. In addition to original articles, the journal publishes review articles on selected topics concerning wood science and related fields. The editors welcome the submission of manuscripts from any country.
