    The photon emission in visible range was measured on the surface of human body by means of low noise photomultiplier system. Changes of this photon emission in the course of the period of 24 hours and changes due to skin temperature alterations are investigated. In order to find out the dynamics and rate of the changes of this photon emission, several human 

subjects are measured according to three basic measurement protocols: long term 

measurement in the course of 24 hours, measurement of photon emission under induced 

cooling of skin, measurement of photon emission under spontaneous cooling of skin. Photon 

emission in the course of the 24 hours was investigated on hands to found that under normal 

physiological conditions it may vary to 70% around daily average.
