| Popis: | Humans spontaneously emit visible radiation from their skin, which is known as biophoton or ultra-weak photon emission (UPE). Up to date, UPE intensity changes according to different external and internal factors have been reported. However, the influence in the human UPE of negative emotional states has never been studied despite their clinic and forensic interest. In this work, an ad hoc system based on a high-sensitive CCD detector was developed to detect and image UPE from human's upper body. Then, the UPE emitted by the upper part of the body of nine volunteers was imaged in two different personal states: (i) when subjects were feeling relaxed; and (ii) when they were emotionally stimulated to feel anger. For all the volunteers, the relative measurement of UPE intensity was higher when feeling anger than when feeling relaxed. Due to the relevance of this disruptive idea and the horizon this knowledge can provide, this proof of concept must be followed by further experiments. An increase in the number of subjects will be accomplished in order to enhance these preliminary results and propose UPE as a new physiological parameter of negative emotional states.
