Characteristic Odor Emanating From Skin During Emotional Tension

Abstract

Humans frequently experience the transmission of the psychological state of people around them. Gas emanating from human skin is known to vary depending on body condition and/or food intake. This characteristic is gaining substantial scholarly attention because skin gas can be an effective non-invasive biomarker to know body condition. The study focuses on the relationship between psychological status and skin gas, which remains unclear to date. It demonstrates that an identifiable odor containing allyl mercaptan and dimethyl trisulfide is released from human skin during psychological stress and tension. An interview confirms a possible scenario where such a characteristic odor reproducibly appears. Undoubtedly, the scene is extreme. Furthermore, the study found that individuals who perceive this tension-stress model odor experience psychological tension, confusion, and fatigue (Profile of Mood States scale). The result indicates the possibility of human non-verbal communication through odor, which could enhance understanding of human interaction.

Highly Sensitive and Selective Gas Sensors Based on NiO/MnO2@NiO Nanosheets to Detect Allyl Mercaptan Gas Released by Humans under Psychological Stress

“…[ 8 ] According to the 2018 Report of Nihon Keizai Shimbun [ 9 ] and a well‐known Japanese cosmetics company Shiseido Co., Ltd., [ 10 ] bad smells in the breath of people under psychological stress, often described as “onion smell,” are caused by the presence of AM and dimethyl trisulfide (DMTS) gas, and wrote the papers. [ 11 ] Excessive psychological stress leads to various adverse effects, including nervousness, anxiety, irritability, depression, tension, and other negative emotions, thereby affecting one's sense of happiness. Long‐term continuous psychological stress may lead to health‐related problems by reducing immunity, by inducing various diseases, such as migraines, heart diseases, skin diseases, and cancer, and by affecting chronic diseases.…”

Facet-Controlled Synthesis of CeO2 Nanoparticles for High-Performance CeO2 Nanoparticle/SnO2 Nanosheet Hybrid Gas Sensors

“…Thus, we developed two types of hybrid gas sensors, viz., {100} CeO 2 nanocubes/SnO 2 nanosheets and {111} CeO 2 nanooctahedron/SnO 2 nanosheet sensors and evaluated their performance in the sensing of various gaseous species, including acetone, hydrogen, ethanol, ammonia, acetaldehyde, and allyl mercaptan. Acetone has attracted significant attention in recent years owing to its role as a marker for diabetes, metabolism, and exercise, while allyl mercaptan is a stress odor marker, − which is particularly important, given the increasing demand for stress checks in corona vortices. Furthermore, ammonia is a known marker of fatigue and stress odor.…”
