• Description:
  A whole-body model with tissue-blood interaction was simulated to predict (1) cooling during cold water immersion of the human body in water temperatures of 18.5 degrees Celsius, 10 degrees Celsius, and 0 degrees Celsius and (2) heating of the human body at walking intensities of 0.9, 1.2, and 1.8m/s for 30 min. The transient responses of body and blood temperature were obtained by simultaneously solving Pennes' bioheat and energy balance equations. Predicted survival time at 0 degrees Celsius was around 39-50 min. During exercise with sweating, core body temperature was regulated within 0.25 degrees Celsius of its steady state value of 37.23 degrees Celsius. [Description provided by NIOSH]
