Figure 4
(A) Two representative recordings of exercise-induced sweating demonstrating simultaneously the timing points of informing the heatstroke risk (circle) and noticing the feeling thirst (level light+, level middle++, level severe+++). (a) ~ 40 years old female and (b) ~ 40 years old male. (B) The relationship between the informing point for heatstroke risk and the self-identification of thirst response in 12 participants. The abscissa shows each participant. The ordinate is the time difference between informing point of heatstroke risk (zero) and self-identification thirst response. The rest 4 participants did not identify the thirst response during the 30 min physical exercise.
