Abstract :
Exposure to heat and heat stress that most people encounter during daily activities or activities in the workplace will have an impact on human physical activity. The aim of this study was to discuss the effects of heat stress in the 22 districts on citizenships of Tehran. For this purpose, the questionnaire data has been used. This research was descriptive and fieldwork was done and a questionnaire was used for data collection. This questionnaire was performed according to a sample size of 385 cases and through using Cochran's formula. For analysis the data of questionnaire was used SPSS and MATLAB software. The findings of descriptive showed that 60% of the respondents were female and 40% men. Since weight has almost direct connection to heat stress, the evaluation of the weight class diversity can be almost suitable for the analysis of the factors and mental responses of heat stress on citizenships of Tehran. Based on this issue, 32.7% have a weight between 55 and 65 and 29.09% have weight more than 75 kg. In order to analysis, the role of heat stress on citizenships of Tehran factor analysis and cluster analysis have been used. The results indicated that based on factor analysis, heat stress has the most effects on the calm of soul and spirit, fatigue and heatstroke and decreased activity and increased transpiration of the body, cramps, pulmonary and heart disease. According to cluster analysis, cardio pulmonary disease and cramps, the calm of soul and spirit and fatigue, dizziness, heatstroke and decreased activity and increased transpiration have been affected respectively. The study showed that the effects of heat stress on gender, type of occupation, marriage, celibacy, male and female and there is a significant relationship between heat stress and gender, occupation and age while marital, celibacy and weight don't have influence on heat stress.
