ABSTRACT
Objective: The purpose of this study was to examine the effects of bathtub bathing (BB) on sleep and working efficiency of healthy young adult students. Furthermore, the effects of BB and prolonged increased body temperature from the use of insulating sheets and sleeping bags after BB (warming after BB: BBW) on sleep and working efficiency were investigated. Subjects: Eighteen (six males, 12 females) healthy young students (19.6±0.7 years old, mean±SD) who habitually took showers instead of baths participated in this study. Informed consent was obtained from all of the subjects, and the study was approved by the Ethics Committee of Kumamoto Health Science University. Methods: Subjects were randomly assigned to two groups (n=9 in each group). The subjects in the BB group were immersed in their home bathtub to the supraclavicular level and instructed to rest for 10 min with the temperature regulated at 41°C. The subjects in the BBW group followed the same bathing protocol, and they then rested in a sleeping bag and sheet for 30 min in order to keep their bodies warm. The length of each study period was 2 weeks in a crossover design. After the 2-week-long washout periods, the subject groups were switched. The subjects were evaluated with the Oguri-Shirakawa-Azumi sleep inventory, MA version (OSA-MA), which utilizes a visual analog scale (VAS) with which subjects rate their sleep when they wake up, and Purdue Pegboard Assembly test. These tests were employed before and after the BB and BBW sessions, resulting in four testing periods in the 6-week period. Results: Sleep rating on the OSA-MA was no significant difference in both the BB and BBW groups compared to ratings recorded after showering. The subjects in the BB and BBW groups had significantly increased VAS ratings for “Feeling of sound sleep,” “Refreshing,” and “Lightness of the body” compared to the ratings after showering. The mean Purdue Pegboard test scores of the subjects in both the BB and BBW groups were significantly higher than those recorded after showering. Discussion: Changing bathing style from shower to BB or BBW improved the working efficiency of students on the Purdue pegboard test. BB and BBW resulted in soothing effects owing to improvements in the subjects’ quality of sleep.
