Identifying stress markers in skin gases by analysing gas collected from subjects undergoing the Trier social stress test and performing statistical analysis

Abstract

In recent years, there has been great interest in mental health disorders. It is very important for people with mental health disorders to protect themselves from the stressful conditions that can occur as part of daily life before their symptoms become worse. We attempted to identify stress markers in skin gases in order to study the stress condition non-invasively in real time. We investigated changes in the skin gas components relative to the normal skin gas components of the subjects when stress was induced in the subjects using the Trier social stress test method, and we attempted to identify stress markers from those changes. We used a statistical analysis method and identified six stress markers in skin gases released from the armpits of the subjects.
