Research on Physiological Reactions to Bath Salts Aroma

Zhiwei Yin, Mamoru Takamatsu


The bath salts is high-profile as its distinctive aroma makes people relaxed with fresh and energetic feelings. EEG is analyzed with the lavipeditum bath method in this study and the physiological reactions (relaxation effects) are discussed and investigated in order to provide basic data for developing the practical products that can make life more comfortable and affluent by quantification for its effect. The experiment demonstrates that the physiological reaction generated by bath salts aroma is composed of the factor of energy difference value of the mid-alpha wave of the frontal lobe in the emotion field. The analysis on energy difference value of the mid-alpha wave  that can cause physiological reaction in this experiment. In general, the aroma that induces a higher physiological reaction is the pomelo, green apple, sakura, rose, chamomile, peppermint for both sexes.
