Abstract: In this study, the research method of field experimental test and questionnaire survey was used to select college students without sleep disorders as experimental subjects, and to study the influence patterns of different sleep thermal environments (22℃, 26℃, 30℃) on thermophysiological parameters and sleep quality of the subjects. The results of the study showed that the thermophysiological parameters and sleep quality of the subjects were significantly different in different sleep thermal environments. The mean skin temperature of the subjects during sleep showed the same trend of change in different thermal environments, and its mean value increased significantly with the increase of ambient temperature, and there was less individual variability in the skin temperature change of the subjects in the neutral environment (26℃), which made their sleep smoother; the blood oxygen saturation decreased with the increase of ambient temperature, and the change of the heart rate was correlated with the quality of sleep of the subjects. Sleep quality was highest in neutral environments, next in colder environments (22°C), and worst in hotter environments (30°C). The mean skin temperature of the subjects changed according to the stage of sleep: the deeper the sleep, the lower the skin temperature, and the lighter the sleep, the higher the skin temperature.
