In this talk, the present knowledge of chronobiological rhythms in spontaneous ultra-weak photon emission (i.e. biological autoluminescence) from humans is summarized. The studies available are reviewed and compared to each other. The studies conducted so far show that UPE in humans exhibits ultradian, circadian and infradian rhythms. These rhythms need to be considered when performing UPE measurements in humans and provide unique physiological information. Further research into the chronobiological aspects of UPE in humans is not only relevant for basic physiological research but also has the potential to demonstrate the importance of characterizing the UPE rhythmicity as a method for medical diagnostics.
