Challenges to Temperature Regulation When Working in Hot Environments

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 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 ...

A model for tracking temperature variation in cold and hot metal working conditions during machining operations

This paper presents a mathematical model that could assist in measuring, monitoring and controlling tem-perature variation in cold and ‘red-hot’ metal working conditions of machining. A numerical analysis tech-nique of the temperature distribution, based on the theory of complex applied potential, was carried out using the principles of relationship analysis between the paths of heat supply in ...

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...
