Radial Pressure Pulse and Heart Rate Variability in Heat- and Cold-Stressed Humans

Figure 4

Effects of thermal stresses on the physiological functions. (a) systolic and diastolic pressure decreased after heat stress and increased after cold stress, (b) heart rate decrease after heat stress and increase after cold stress, and (c) left hand temperature increased and right hand temperature decreased after heat stress, and temperatures of both hands decreased after cold stress. ‡: left-hand temperature versus right-hand temperature in baseline control and 𝑃<.01; **𝑃<.01 compared with the control.
