Our sense of smell is something most of us rarely think about.

Yet it may play a far bigger role in stress, emotional regulation, nervous system balance, and healing than many people realize.

In a special webinar leading up to the Metabolic Health Day Conference, Jodi Cohen, founder of Vibrant Blue Oils and a Metabolic Health Day speaker and sponsor, shared a fascinating and deeply personal conversation about the connection between scent, stress regulation, trauma, emotional resilience, and healing.

The discussion explored how smell directly impacts the brain, why the nervous system matters in healing, and how simple sensory tools may help people feel more grounded, calm, and regulated during difficult seasons of life.

Healing Isn’t Just Physical

One of the most powerful themes from the conversation was the idea that healing is not always just about protocols, supplements, or treatments.

Sometimes, it begins with helping the body feel safe.

As Jodi explained, chronic stress can keep the body stuck in a constant fight-or-flight response — a state where the nervous system prioritizes survival over repair and restoration.

When the body perceives danger, many healing functions can become disrupted, including:

• digestion

• sleep

• immune function

• emotional regulation

• focus and cognitive clarity

• recovery and repair processes

That’s why emotional resilience, nervous system regulation, and mental health support are becoming increasingly important parts of broader healing conversations.

Why Smell Matters

According to Jodi, smell has a unique relationship with the brain because scent bypasses the analytical parts of the brain and connects directly to the limbic system — the area involved in emotions, memories, stress responses, and survival patterns.

Unlike other senses, smell has direct access to emotional centers in the brain.

That’s one reason certain scents can instantly transport us back to childhood memories, feelings of safety, grief, comfort, or fear.

It’s also why smell may have the ability to quickly shift emotional states and help regulate stress responses.

As Jodi shared during the webinar:

“Smell can calm stress. Smell can signal safety.”

Trauma, Stress, and the Nervous System

Throughout the conversation, Jodi spoke openly about her own experiences with trauma, loss, overwhelm, caregiving, and grief — and how nervous system support became an important part of her healing journey.

She described how emotional overwhelm can leave people stuck in survival mode, unable to fully access the body’s restorative healing state.

For many people navigating cancer, chronic illness, caregiving, burnout, or major life stressors, this conversation may feel deeply familiar.

Sometimes people are:

doing everything “right”
following protocols
changing nutrition
taking supplements
trying to stay positive

…and still feeling stuck.

The webinar explored how unresolved stress, emotional overload, and nervous system dysregulation may play a role in why healing can sometimes feel harder than expected.

The Vagus Nerve and Emotional Resilience

Another important topic discussed was the vagus nerve — a key part of the parasympathetic nervous system that helps regulate rest, digestion, emotional balance, and recovery.

Jodi shared how supporting the vagus nerve became part of her own stress regulation practices and how scent-based approaches may help support calming and grounding responses in the body.

The conversation also touched on:

• limbic system regulation

• trauma responses

• emotional overwhelm

• fascia and tension patterns

• nervous system safety signaling

• heart coherence and emotional regulation

All through the lens of helping people better understand the connection between emotional health and physical well-being.

Small Moments of Safety Matter

One of the most meaningful takeaways from the discussion was this:

Sometimes healing starts with creating small moments of safety.

Moments to pause.
Moments to breathe.
Moments to regulate.
Moments to reconnect with ourselves.

As Jodi shared near the end of the conversation, referencing Viktor Frankl:

“Between the stimulus and the response there’s a space… and in that space lies our power to choose our response.”

Conversations like these help expand the understanding of healing beyond physical symptoms alone.

They remind us that:

• mental health matters

• emotional resilience matters

• stress matters

• feeling safe matters

And that healing is often deeply connected to the state of the nervous system.
