Results

Touching brushed or sanded sugi significantly decreased oxy-Hb concentrations in the left and right prefrontal cortices, increased ln(HF), and decreased the ln(LF/(LF?+?HF)) ratio compared with touching marble. Thus, our findings indicate that compared with touching marble, touching sugi with the palm induces physiological relaxation, as indicated by calmer prefrontal cortex activity, higher parasympathetic nervous activity, and lower sympathetic nervous activity.
