Abstract :

The aim of this paper is to analytically investigate the autocorrelation pattern and cluster analysis of the heat stress on the Tehran habitants. The MATLAB software has been used in relating to Hot Spot. The results on the effects of heat stress based on spatial autocorrelation pattern show that heat stress had a greater effect on the mental health of the residents in central, eastern and northeastern districts. While this had a lesser effect in the southern and western districts. There was a greater physical effects of heat stress on livelihood of residents in the central, southern, northern and northwestern. This show a significantly less effects for residents in the western and northeastern residents. The results also indicated that based on cluster analysis of heat stress has been affected on cardio pulmonary disease and cramps, calm of soul and spirit and fatigue, dizziness, heatstroke and decreased activity and increased transpiration.
