When heat gain exceeds heat loss, symptoms of heat strain (the physiological response to heat stress) can develop. There is no specific standard or temperature for identification of heat stress. Symptoms of Heat Exhaustion: WebApr 5, 2024 · The body also exchanges small amounts of heat by conduction and breathing. By conduction, the body gains or loses heat when it comes into direct contact with hot or cold objects. Breathing exchanges heat because the respiratory system warms the inhaled air. When exhaled, this warmed air carries away some of the body's heat. radar\u0027s vy

"WebMar 16, 2011 · The ultimate criterion in terms of heat strain is an oral temperature of 37.5 ºC. If P3 ≤90 bpm and P3 – P1 = 10 bpm, this indicates work level is high but there is little increase in body temperature. If P3 >90 bpm and P3 – P1 10 bpm, the stress (heat + work) is too high and action is needed to redesign work. " - Body physiological response to heat stress
