Thermoregulatory disorders and illness related to heat and cold stress
Thermoregulation is a vital function of the autonomic nervous system in response to cold and heat stress. Thermoregulatory physiology sustains health by keeping body core temperature within a degree or two of 37°C, which enables normal cellular function. Heat production and dissipation are dependent on a coordinated set of autonomic responses. The clinical detection of thermoregulatory impairme...
متن کاملHeat Stress in Aviation
INTRODUCTION It is generally agreed that man’s adaptations to the heat are well developed, conversely when naked in the cold his physiological adjustment very poor. It could also be argued that humans are historically tropical as: They rely on physiological adjustment in the heat but behavioral adjustments in the cold. The thermo-neutral ambient temperature for nude humans and the temperature n...
متن کاملHeat stress and acclimation.
Heat stress reduces the capability for sustained exercise. On the other hand, with repeated exposures to hot environments, exhaustion is delayed. This paper examines the hypothesis that high core temperature might be the ultimate cause of the fatigue and inability to continue to exercise in hot dry environmental conditions. It is suggested that a high core temperature is the ultimate cause of f...

Chester White pigs weighing 65 to 70 kg bearing surgically implanted catheters were placed under a surgical plane of anesthesia and subjected to programmed increases in dry bulb and dew point temperatures from 27C at a rate of 5 ~ per hour (70 to 80% relative humidity) until heart and respiratory action ceased. Changes in plasma adrenocorticotropin (ACTH), adrenocorticoids and growth hormone le...
