Body Temperature Regulation in Hot Environments

Body Temperature Regulation in Hot Environments

Organisms in hot environments will not be able to passively dissipate metabolically generated heat. Instead, they have to revert to evaporative cooling, a process that is energetically expensive and promotes excessive water loss. To alleviate these costs, birds in captivity let their body temperature increase, thereby entering a state of hyperthermia. Here we explore the use of hyperthermia in ...

Challenges to temperature regulation when working in hot environments.

The focus of this review is upon acute exposure to hot environments and the accompanying physiological changes. The target audience includes physiologists, physicians and occupational health and safety practitioners. Using the principles of thermodynamics, the avenues for human heat exchange are explored, leading to an evaluation of some methods used to assess thermally-stressful environments. ...

Body temperature regulation in diabetes

The effects of type 1 and type 2 diabetes on the body's physiological response to thermal stress is a relatively new topic in research. Diabetes tends to place individuals at greater risk for heat-related illness during heat waves and physical activity due to an impaired capacity to dissipate heat. Specifically, individuals with diabetes have been reported to have lower skin blood flow and swea...

Effects of brainstem lesions on temperature regulation in hot and cold environments.

LIPTON, J. M., P. E. DWYER, AND D. E. FOSSLER. Effects of brainstem lesions on temperature regulation ilz hot and cold environments. Am. J. Physiol. 226(6) : 1356-l 365. 1974,--Rectal temperatures (T,) of rats with electrolytic lesions or knife cuts in the brainstem were recorded during 7-h exposures to 5 and 35*C. Rats in which the preoptic/anterior hypothalamic (PO/AH) region was destroyed or...
