Aims: In Japan, although evening bathing as a means of both cleaning and relaxation has been a wellestablished custom from ancient times, the prevalence of morning baths has increased in Japan in recent years. The effects of morning bathing on human sleep quality have not yet been revealed. Thus, we aimed to clarify the effects different bathing method on human sleep quality.
Methods: The first night, the subject entered the laboratory at 19:00 and went to bed at 24:00. On the second day, the subject got up at 07:00 and either showered, took a mist sauna, or did not bathe, between 07:10 and 07:20. Each hour after that, the subject completed an alpha attenuation test (AAT), Kwansei-Gakuin sleeping scale (KSS) test and subjective evaluations from 09:00 to 17:00. We measured the melatonin concentrations at 22:30, .. Read More»
