Biophoton emission from the hands

Biophoton emissions from the palms and the backs of the hands were measured for twenty healthy subjects. About 34 % more biophotons (in the range of 300-650 nm) were observed from the hands than from the background, but no significant difference was observed between the palms and the back of the hands. No marked dependence on age or gender was found. Photo-counting statistics were analyzed to study the coherence of biophotons, and the measured biophotons from the hands lacked the usual coherence because of the large area and the long measurement time.
