Description

We investigated the heart rate variability and the thermal environment during sauna and rest in 42 healthy subjects aged 20 to 40 who had experience with sauna. Subjects wore a wearable heart rate sensor on their non-dominant arm before starting the sauna. Then, they did sauna, took a cold-water bath, and rested. The number of repetitions and duration of each activity were optional. After each sauna session, the subjects answered a web survey regarding the thermal environment of the sauna, their satisfaction after sauna, and their subjective sense of "totonou". The rMSSD significantly decreased during sauna and increased during rest. There was no difference in sauna satisfaction depending on the thermal environment, but a significant correlation was observed between subjective sense of "totonou" and the difference in rMSSD during sauna and rest. Subjective sense of "totonou" was significantly higher when the duration of exposure to rest was longer than sauna, and when there was a larger difference in rMSSD between rest and sauna. The "totonou" feeling from sauna was considered to be achieved by ensuring sufficient time for rest in which parasympathetic nervous activity predominates.
