The study is designed to investigate convenient techniques for evaluating sleeping quality.Methods:A double-blind randomized trial was carried out on university students with sleeping disorders who were given Sheng’an capsule or the placebo respectively for 108 days. Three features of infrared thermal images (ITI), i.e. the eye feature (EF), neck feature (NF) and right upper quadrant feature (RUQF) were observed.Results:The effect of Sheng’an capsule was satisfactorily reflected by ITI. After the trial, male EF value, male RUQF value and its change, and female NF value and its change were statistically lower than those of the control group (P≤0.01 or ≤0.05). With the relative efficacy rate of 87.5% for the trial group and 25.0% for the control, there was significant difference between the two groups (P=0.0001). ITI also showed sex-related differences in the control group at end of the trial.Conclusion:There are broad prospects for ITI application in sleeping study.
