Acclimatization

• the ability of the body to undergo physiological adaptations so that the stress of a given environment, such as high altitude, is less severe.
• The gradual adjustment of the body to new climatic or other environmental conditions, for example, the adjustment to low levels of oxygen at high altitudes.
• the adaption of an organism to its environment. In Everest terms it means to get adapt to the higher altitude
• The physiological adjustment or adaptation by an organism to new physical and/or environmental conditions. With respect to water, it is frequently used in reference to the ability of a species to tolerate changes in water temperature, degradation of water quality, or increased levels of salinity.
• the physiological changes that allow the body to adapt or get used to the effects of a new environment, especially low oxygen saturation at higher elevations
• the adaptation of a living organism (plant, animal or micro-organism) to a changed environment that subjects it to physiological stress.
• The physiological and behavioral adjustments an organism makes in response to changes in its environment.
• adaptation to a new climate (a new temperature or altitude or environment)
• Acclimatization is the process of an organism adjusting to chronic change in its environment, often involving temperature, moisture, food, often relating to seasonal climate changes. (In laboratory conditions, this process is controlled to one variable change only and is termed "Acclimation").
• The act of acclimatizing; the process of inuring to a new climate, or the state of being so inured
