Researchers have found that intentionally smelling certain scents can have a measurable impact on your physiology and emotions. The scent receptors in your nose are directly connected to the brain's limbic system, the emotional center, allowing smells to bypass rational thought and immediately impact mood. Factors like memory, culture, and genetics shape our personal responses to different scents, so finding the right fragrances for you is key to harnessing the mood-boosting power of smell.

Why it matters

In an increasingly digital world, deliberately engaging with our sense of smell can be a powerful way to slow down, connect with our environment, and access deep emotional responses. Understanding the science behind how smell impacts the brain and body can help people incorporate more scent-based practices into their daily lives for improved mental health and wellbeing.

The details

When you inhale a scent, odor molecules bind to receptors in your nose and travel directly to the olfactory bulb in the brain, bypassing the thalamus relay station that other senses like sight and sound must pass through. This direct connection to the limbic system, the brain's emotional center, is what gives smell such a profound and immediate impact on mood and memory. Certain scents like lavender and citrus tend to have calming or energizing effects, but individual responses can vary greatly based on personal history and genetics. Deliberately slowing down to smell something for 30 seconds or more can activate the parasympathetic nervous system, slowing the heart rate and inducing a meditative state.

  • Researchers have been studying the connection between smell and emotion for decades.

What they’re saying

“Mood change is one of the more common effects of smelling something. Olfaction has a more direct impact on emotion than any other sense. There's no question about that.”

— Pamela Dalton, Cognitive Psychologist

“Whenever I read these blanket statements about, 'Oh, the odor of lavender will relax you no matter what'—that blanket statement is rarely true in olfaction. We have a huge complexity at the level of biology, and then we have all of our experiences that are hard to account for.”

— Valentina Parma, Senior Director of Multisector Engagements

“To witness that space through other people's noses is an incredible thing.”

— Kate McLean-MacKenzie, Designer and Researcher

What’s next

Researchers continue to explore the complex relationship between smell, emotion, and memory, with potential applications in mental health treatment and sensory design. Individuals can start incorporating more intentional 'smell catching' into their daily lives to experience the mood-boosting benefits.

The takeaway

Our sense of smell is a powerful but often overlooked tool for improving mental wellbeing. By taking the time to deliberately engage with scents that resonate personally, people can access deep emotional responses, shift their mood, and reconnect with their environment in a more embodied way.
