The main aim of the diploma thesis is to determine if BMI (Body Mass Index) in humans is related to the indoor room temperature. Lower room temperature can lead to the activation of brown adipose tissue (BAT), thereby increasing energy expenditure. Because the thermal comfort is individual to some extent, the task is to determine whether there is a correlation between BMI and the frequency of perceived thermal discomfort. The research was attended by 202 respondents in the age range of 3 to 27. All were measured and weighed, and then the temperature habits were recorded through questionnaire. A group of students underwent more detailed data collection. For the evaluation of the data was used PCA (Principal Component Analysis) and regression analysis, for determining the influence of the room temperature, data were weighed by the coefficient of the thermal insulation during the night. The results showed that BMI, respectively the percentile BMI class of respondents in-creases with increasing average bedroom night temperature. Results are less clear for the age categories with no dependency between BMI and room temperature in the youngest age category, significant correlation in adolescent females and adult men, but not signifi-cant correlation in adolescent males and adult females. Evaluation of 87 responses from adolescent and adult respondents to the question regard-ing the frequency of subjective cold feeling showed that the more they felt the coldness in their dwellings, the lower was percentile BMI class and BMI in different age groups. Based on these results we can state that the room temperature during sleep is another sig-nificant factor influencing BMI and lowering the temperature in the homes could lead to the reduction of population obesity.
