Heat Acclimatization is simply the adaptation of the body according to the environmental conditions prevailing or happening around the body. For example, an organism may expose to cold weather, or hot weather, or humidity, or dusty environment, anything like this, then the organism's body adapts itself according to the environmental conditions. For example, if a person walks over the hills where oxygen level are less than the normal, the human body transports more oxygen in the blood than normal.
