It is of great importance to study the manifestations and the influencing factors of the time-related changes of infrared
thermal images (ITI) of human body since the variable body surface temperature distribution seriously affected the
application of ITI in medicine. In this paper, manifestations of time-related changes of the ITI of human body from three
double-blind randomized trials and their correlation with meteorological factors (e.g. temperature, pressure, humidity,
cold front passage and tropical cyclone landing) were studied. The trials were placebo or drug controlled studying the
influences of Chinese medicine health food (including Shengsheng capsule with immunity adjustment function, Shengan
capsule with sleep improvement function and Shengyi capsule with the function of helping to decrease serum lipid) on
the ITI of human body. In the first thirty-six days of the trials images were scanned every six days and image data in the
seven observation time spots (including the 0, 6, 12, 18, 24, 30, 36 day of the trial) were used for the time-related study.
For every subject the scanned time was fixed in the day within two hours. The ITI features which could reflect the
functions of the health foods were studied. The indexes of the features were relative magnitude (temperature difference
between the viewing area and the reference area). Results showed that the variation tendencies of the trial group and
control group were basically the same in placebo controlled trials and some of the long-term effects of Chinese medicine
health food could be reflected significantly in certain time spots in the first thirty-six days. Time-related changes of the
ITI of human body were closely related with meteorological factors but there were other influencing factors still need to
be studied. As the ITI of human body could reflect the influences of Chinese medicine health foods and are closely
related with meteorology, there are bright prospects for the application of ITI in health monitor.
