Related to Acclimitization: acclimatization to heat
Physiologic adjustment of a person to a different climate, especially to a change in environmental temperature or geographic elevation.
The physiological adaptation of an animal or plant to changes in climate or environment, such as light, temperature, or altitude.
Physiologic adaptation to a variation in environmental factors such as temperature, climate, or altitude.
1. Physiological adaptation to a new environment or situation. Acclimatization to a hot environment may take as long as three weeks, during which undue exposure to heat, or strenuous exercise, may cause HEAT EXHAUSTION.
2. An environmentally-induced functional improvement in a genetically-determined physiological system.
acclimationthe process by which a range of adjustments occur in the body, e.g. in TEMPERATURE CONTROL and RESPIRATION, when an organism is subjected to unusual environmental stresses such as high altitude. See ADAPTATION, PHYSIOLOGICAL.
acclimatizationadjustment of physiological processes in response to a change from the accustomed environment: to heat or cold, or to high altitude. For example, repeated exercise in the heat leads to an increase in maximal sweating rate, but with reduced sodium concentration in the sweat; low oxygen content in the blood at high altitude leads among other adjustments to increased breathing and cardiac output, assisting oxygen supply. See also altitude acclimatization, heat acclimatization, sweating.
the adaptation of an animal to the climatic conditions in an area. The ability to adapt in this way is an important characteristic of livestock.
