Adaptation and extract the onslaught of external factors, the new environment is an important issue. The response to adverse environmentalfactors makes changes in the human body. It primarily affects greatly theimmune system and the circulatory system. The regulation of body temperature in the heat is critical, because of the great potential for lethal hyperthermia. To study attended 10 local people and 10 people, who camefrom other regions of Kazakhstan. People create heat stress lasting 1 hourat ambient temperature + 42°C and 76% relative humidity once and dailyfor 15 days. In people of all groups was measured rectal temperature andmeasured changes in blood cells by method Shilling. Blood for researchwas taken from the vein. The number of blood cells was determined bythe standard technique with using hematology analyzer. The study setthat mechanisms of regulation of body temperature on multiple high temperatures correspond to the maximum and minimum periodic rises of thebody temperature. Adaptive responses to high ambient temperatures mostadaptable people aged 15-18 than in aged 55-60.Key words: adaptation, acclimatization, blood cells, human ecology,homeostasis, stress, temperature.
