Some physiological parameters of human body have the possibility to characterize the change of human thermal sensation. The correlation between human skin temperature, electroencephalogram (EEG) and thermal sensation changes in cold environment, neutral environment and hot environment was analyzed to explore the relationship between human physiological parameters(skin temperature, EEG) and thermal sensation changes in different room temperature environments through objective experiments and human subjective questionnaire surveys. It was found that the mean skin temperature, forehead temperature were significantly related to the changes of thermal sensation and the trend is consistent. During energy analysis of EEG data, the overall thermal sensation of human body at different room temperature is significantly correlated with the spectral power changes of δ band (0.5～4 Hz) and α band (8～13 Hz) and moderately correlated with the spectral power changes of β band (13～30 Hz) using the fast Fourier transform method. Particularly, the average spectral power of the δ, α, and β bands changes more significantly when the human body responds to a cold environment. The variation range of average spectral power per unit thermal sensation vote(TSV) scale in the transition from cold environment to neutral environment is higher than that in hot environment. Human body is more sensitive to the cold environment and also revealed at the aspect of energy physiological parameters of EEG spectral power. [ABSTRACT FROM AUTHOR]
