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...

Heat 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...

The impact of terminal heat stress on yield and heat tolerance of bread wheat

In arid and semi-arid regions of the world bread wheat (Triticum aestivum L.) yield is highlylimited due to late season heat stress, mostly occurring during the reproductive phase. Hence thecurrent study was conducted to evaluate the effect of late season heat stress on grain yield andyield components of 20 spring bread wheat cultivars. For this purpose, a stripe block experimentincluding four ...

Heat 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...
