New methodologies for the collection and analysis of biological samples from psychological, physical and emotional stress are described. Currently, there is little research relating to the elemental, VOC and small molecule changes in biological samples as a consequence of stress on the human body, with much of the current research indicating physical symptoms. This research sought to measure chemical changes in three different categories of stress. The first uses an existing PASAT intervention to induce psychological stress and a further two new methodologies using exercise to induce physical stress and a trapped human in a simulation of a collapsed building to induce emotion stress. Psychological, physical and emotional stress elemental profiles are compared against their respective chemical baseline profiles. Skin samples are collected from the foreheads of participants who endured emotional stress while drool saliva, urine, plasma and forehead skin samples were obtained from physically stressed participants. Furthermore, drool saliva is also obtained from the individual who experienced emotional stress.
