Abstrakt

This study deals with the effect of physiological thermoregulation of the human body at extreme cold thermal condition. It consists of effect of metabolic activity on thermoregulation of the human body, Effect of environmental parameters on the human body. Study focused on extreme cold climate where metabolic activity done on treadmill is analysed. For this Climate chamber have been used where any controlled environment can be created. Project consist of subjective and objective analysis. Effect of cold temperature on the human body was analysed and found hand and foot are cooler than other body parts in an extreme cold environment. Effect of activity on human body was investigated and found during running foot, and hand temperature decreases. Subjective responses were analysed based on individual thermal sensation voted of the subjects. Regression line is drawn between thermal sensation votes and different set point temperature and found neutral temperature.
