Resumen

Purpose

Heat therapies such as hot water immersion, Finland saunas, and Waon therapy have been reported to reduce resting arterial blood pressure. However, hyperthermia imposes physiological and perceptual strains. To acquire a habit of heat therapy, it is ideal to develop a modality that offers therapeutic benefits with minimal strain. Here, we hypothesized that the unique Japanese traditional steam sand heat therapy lowers blood pressure with minimum physiological and perceptual strains.

Methods

Fourteen healthy young male adults underwent three heating procedures, each lasting 20 min: (1) steam sand bath (~ 50 °C), (2) hot water bath (~ 41 °C), or (3) sauna (~ 80 °C) in a randomized counter-balanced manner. Cardiorespiratory responses and perceptions were assessed before, during, and after each heating.

Results

Core temperature increased in the following order: hot water bath > sauna > steam sand bath (all p 0.39). Thermal comfort at the end of heating was lower (i.e., more comfortable) in the steam sand bath compared to the other two conditions (both p < 0.001).

Conclusion

We show that the traditional Japanese steam sand bathing may provide blood pressure-lowering benefits with reduced respiratory and perceptual strains compared to hot water bath and sauna.
