EVALUATION OF HOT ENVIRONMENT IN INDOOR ENVIRONMENTS TO PROTECT AGAINST HEAT DISORDERS

In order to protect heat disorder due to hot environment, the authors have developed a model forpredicting body temperatures, which has the following three characteristics: 1) regulatory thermalsweating is expressed as a linear function of the mean skin temperature under constant metabolic rate,2) sweat efficiency is expressed as a function of skin wettedness, and 3) the effect of wetted clothing,defined as clothing wettedness, caused by dripping sweat on physiological responses is considered.We proposed a prediction formula of heart rate in hot environment based on our model.
