heat acclimatization

heat acclimatization

the process of improvement in tolerance to heat as a result of repeated sessions of exercise in a hot environment, resulting in a measurable improvement in physiological response. The body's response includes increase in the rate of sweating but decrease in sodium in the sweat, preserving salt by the action of aldosterone; increase in skin blood flow and overall control of body temperature as environmental conditions (air temperature and humidity) change. In addition, acclimatization will reduce the incidence and severity of heat illness. See also acclimation.
