Discussion on research routes of using physiological index to evaluate human thermal comfort, work efficiency and long-term health

Analyses the physiological response mechanism of human body to thermal environment. Reviews the research status of using physiological index to evaluate human thermal comfort, work efficiency and long-term health. Points out that the physiological index has great effects on evaluating human work efficiency and long-term health but is merely a secondary means in thermal comfort evaluation. Puts forward three research routes.
