A comparison of nursing techniques advocated for sleep enhancement between nursing textbooks from Japan and English-speaking countries revealed that the application of hot footbaths to induce sleep was unique to Japan.
The aims of this study were to investigate the domestic development, and the historical and cultural background that led to the development of the footbath for inducing sleep in Japan.
Japanese nursing textbooks were reviewed chronologically for descriptions of the purposes of footbath care. When the reason for administering footbaths changed to sleep-enhancement for the first time, the possible contribution of other sleep-enhancement methods employing heat and/or stimulation of blood circulation was examined. The background influencing this transition was also examined.
Footbath care was imported into Japan the end of 19th century when modern nursing education was introduced to the country. In 1879, footbath care was described as a means of alleviating congestive headaches by improving blood circulation. However, the reason for administering footbaths changed over time and it was only in 1960 that hot footbaths were described in a textbook as a means of enhancing sleep.
The authors propose that a nurse developed the idea of administering footbaths to promote sleep by integrating the following knowledge: First, the sleep-promoting effect associated with a hot towel massage, initially described in 1951, was combined with the knowledge that footbaths also improved blood circulation, as initially described in 1876. In addition, nurses recognized that footbaths reminded clients of bathing, and that, based on the nurse's own daily experience, evening baths had sleep-enhancing effects. The nurse-client relationship in Japan was considered to be one of the key factors affecting the background development of this new application of footbaths. Nurses were acutely aware of the sleeping patterns of individual clients, and would have been responsible for his/her daily basic hygiene using hot towels and footbaths.
