A novel, safe and effective far-infrared bathing procedure for health

Arangane and Higashino, 2018 [non-randomized prospective case study; n= 31; male and female; mean age of 39.8±12.3/60.9±7.04] focused on physical nature of ceramic to radiate far-infrared rays when heated adequately. In each session, hot water at 50-52°C was first filled in the bathtub (ceramic beads were completely dipped in hot water) and drained out when temperature of the beads was equilibrated around 50°C. Immediately thereafter, each participant wearing minimal underwear was placed in a bathtub at supine position and buried in heated ceramic beads except for the head and the neck by use of a shovel and kept for 15 min. Participants did not receive any medical therapy or psychological treatment during the program. All data showed no physiological overload for tested individuals, and any biochemical analysis did not present abnormal score. Bacteriological culture grew no pathogens. Results of questionnaires demonstrated that 90% of the participants felt comfort and wished to further repeat the bathing. Therefore, it was concluded that the Enseki method is a safe and well tolerated far-infrared bathing procedure for regeneration and relaxation.
