Emotional body odor:Mechanisms in emotional communication and biological significance
摘要
Abstract
Emotional body odors(EBOs)are volatile organic compounds that arise when exocrine glands activated by the sympathetic nervous system secrete body fluids,which skin microbes then metabolize into volatile molecules.These molecules encode emotional information as chemical signals.When perceived,EBOs commonly elicit similar affective states in receivers,supporting olfactory emotional communication;however,their mechanisms and biological significance remain unclear.Evidence indicates that negative EBOs(for example,fear,anger,anxiety)recruit threat-defense systems in receivers,altering autonomic arousal,attentional bias,and defensive behavior.By contrast,positive EBOs promote emotional contagion and social bonding and can enhance physiological regulation and some cognitive functions.Together,these effects point to a bidirectional defense-bonding regulatory system that may increase social survival fitness.To clarify the evolutionary significance of these regulatory functions,this paper proposes the"communicative chemical evolution hypothesis."The hypothesis describes a functional continuum from chemical cues(metabolic by-products),to chemical signals(socially exploited cues),and ultimately to pheromones(evolutionarily stabilized signals),and it highlights relevant temporal dynamics and selective mechanisms.Future work should combine multi-person social-interaction paradigms,twin designs,virtual reality,and high-resolution chemical analyses to test this framework.Such research may reveal olfactory intervention targets for disorders characterized by impaired emotion recognition or expression.关键词
