Effects of heat

Description

Adverse effects resulting from a failure to maintain normal body core temperature on exposure to excessive heat. Vigorous exercise, insulation by clothing (e.g. protective clothing) or an inability to sweat normally (e.g. genetic hypohidrosis or autonomic neuropathy) may be contributory factors.
