How Emotional Changes Affect Skin Odour and Influence Others
We’ve all heard the phrase “fear has a smell” and new research shows it’s not just a saying. Scientists have discovered that emotional changes, especially stress, can alter our skin odour in measurable ways. These subtle scent shifts don’t just affect us and they can also influence the mood and stress levels of people around us.
In a study, researchers monitored participants during job interview simulations. Emotional stress activated the sympathetic nervous system and increased cortisol, both reliable stress markers. During these moments, skin gas released sulfur compounds like allyl mercaptan (AM) and dimethyl trisulfide (DMTS), producing an odour distinct from normal sweat. When recreated in lab settings, the scent caused test subjects to report spikes in tension and confusion, confirming its social impact. Unlike odours from exercise, which come from sweat, stress odors originated from a different biological process tied directly to emotional change.
This means that our emotional states don’t just stay inside our heads because they literally radiate out into the world. For workplaces, relationships, and high-pressure environments, it suggests stress may ripple outward, silently amplifying tension in groups.
Elsha Kim, wellness advocate and founder of bronzebody®, has seen firsthand how emotions and skin health are deeply connected.
“Many people think of stress as something invisible, but our skin tells a different story,” says Kim. “When emotional shifts trigger chemical changes, it doesn’t just affect how we feel, it can literally affect how we smell and how others respond to us.”
How to Keep Your Skin Clear of Stress Signals
- Mind the moment: Short breathing exercises before stressful events can calm your nervous system, reducing stress signals.
- Sweat it out wisely: Exercise releases sweat but not stress odor compounds, so physical activity may help balance stress hormones.
- Stay hydrated: Proper hydration supports skin function and can help dilute metabolic byproducts.
- Choose stress-buffering foods: Antioxidant-rich foods may reduce oxidative stress that contributes to skin changes.
- Mind-skin rituals: Skincare routines paired with relaxation techniques (like facial massage or aromatherapy) can help reduce stress and its impact.
“Skin odour is a reminder that our bodies communicate in ways we often overlook. When we’re stressed, our skin can emit subtle chemical cues that others can pick up on subconsciously. This can change how people perceive us, even before a single word is spoken,” Kim explains.
She adds, “This also explains why certain environments, like offices under pressure or social settings with heightened tension, can feel more stressful than they should. It’s not just the atmosphere; it may be the collective stress people are quite literally sensing through odour molecules.”
“The good news is that awareness gives us tools,” Kim notes. “By managing stress proactively through rest, nutrition, movement, and mindful rituals, we not only feel better ourselves, but we may also reduce the impact of stress signals on those around us. It’s about creating a healthier environment for everyone.”
