When it comes to making smart, strategic decisions in business, many leaders focus on mindset, skill, and strategy. But trauma therapist, trainer, and author Rebecca Kase says there’s something far more fundamental influencing success: the state of your nervous system. 

Known for blending polyvagal theory, neuroscience, and somatic practices, Kase has built a career helping people — from therapists to high-performing entrepreneurs — understand how regulation shapes performance. Her latest book, “The Polyvagal Solution: Vagus Nerve-Calming Practices to Soothe Stress, Ease Emotional Overwhelm, and Build Resilience,” offers a blueprint for anyone ready to harness their psychology to improve their business outcomes. 

Rebecca Kase on the Link Between Regulation and Leadership

The nervous system runs on the same hardwiring humans have relied on for millennia to survive danger. In the modern workplace, those “survival states” aren’t usually triggered by wild animals or physical threats — they’re activated by high-stakes stressors like a tense negotiation, a looming deadline, or a conflict with the board. Physiologically, the brain and body don’t know the difference: the same systems that once mobilized to outrun a predator now redirect energy toward fast, defensive reactions. That’s why, in these stress states, creativity narrows, strategic thinking slips, and communication can falter — exactly when leaders need them.

Her approach is rooted in Polyvagal Theory, developed by Dr. Stephen Porges, which highlights the vagus nerve as a central player in regulating emotional state, stress response, and the capacity to connect with others.

“When you strengthen this system, you’re not just boosting your personal well-being,” Kase explains. “You’re upgrading the very foundation of leadership — clearer decisions, stronger collaboration, and greater adaptability in the face of change.”

Turning Survival Mode Into Strategic Mode

Many entrepreneurs normalize high stress as the cost of ambition, but the numbers paint a sobering picture. A 2025 survey found that 34 percent of entrepreneurs experience burnout, while nearly 46 percent report high stress, and over 87 percent struggle with at least one mental health issue.

Constant activation of the sympathetic nervous system, which triggers “fight or flight” responses, can erode judgment, fuel depletion, and strain relationships. Kase challenges this hustle culture approach by encouraging leaders to shift into the ventral vagal pathway — a state associated with calmness, connection, and emotional clarity. 

“Many people, including leaders and CEOs, force themselves to navigate life by pushing or forcing themselves to ‘power through’ stress,” she says. “But what they may not realize is that their nervous system is what’s really running the show.”

The vagus nerve is a key driver of heart rate variability (HRV) — a well-established indicator of overall health and resilience. Recent studies have shown that higher HRV is associated with a more emotionally resilient nervous system that can adapt to challenges, potentially supporting better performance, decision-making, and a calm, confident presence that may inspire teams.

Together, these findings demonstrate that strengthening vagal tone — often measured through HRV — may lead to lasting improvements in emotional regulation, resilience, and stress management. HRV biofeedback and simple daily practices, such as intentional breathing, movement breaks, and genuine social connection, may stimulate the vagus nerve, shifting the nervous system into a state that supports clarity, composure, and adaptability. For leaders, this isn’t just self-care; it’s a strategic reset that helps keep decision-making sharp and perspective intact under pressure.

The Science Behind Calm Leadership

Kase doesn’t just offer tools, however. She invites readers into a neuro-informed life, one where we respond rather than react, becoming aware of how our brain and body process stress and using evidence-based tools to regulate it, rather than feeling controlled by it.

“When our system is regulated,” she explains, “we make decisions from clarity instead of fear, access creativity, and connect authentically.”

Similar to the aforementioned randomized control trial from 2023, a 2025 study published in “Applied Psychophysiology and Biofeedback” found that participants who increased their resting HRV during a five-week HRV-biofeedback program experienced greater reductions in negative emotions, showing a direct link between vagal regulation and emotional resilience. 

These findings highlight what Kase has been teaching for years: when leaders regulate their nervous systems, they’re not just calmer but more effective, strategic, and innovative.

By modeling regulation, leaders set the tone for the entire organization. When executives lead from a place of calm presence, it fosters team cohesion, sparks innovation, and builds long-term resilience. As Kase puts it, “It’s about working with your biology — not against it — to shift from merely surviving to truly thriving.”

According to Kase, rewiring your stress response opens the door to sustainable leadership. Her book offers strategies to interrupt the body’s stress response, cultivate stress resilience, and achieve lasting calm in the face of chaos.

The Ceo’s Nervous System Toolkit

Through her trainings at The Trauma Therapist Institute and in her book, “The Polyvagal Solution,” Kase outlines practical tools that business owners and executives can use, including:

• Breathwork before high-stakes meetings to regulate stress responses.
• Mindful movement breaks to release tension and restore focus.
• Body awareness practices to catch stress patterns early.
• Positive connection rituals to build resilience and maintain perspective.

She teaches leaders to treat these tools as daily maintenance, not crisis interventions. Just as a business runs on consistent operational systems, a nervous system thrives on regular tuning. 

These tools, she emphasizes, are not “extras” but performance essentials that help leaders operate at their full potential. When practiced consistently, they can help support your key asset, your nervous system, in a state that may promote personal well-being and contribute to the health and success of your organization.

Your Business Grows at the Speed of Your Regulation

Kase’s message is straightforward: you can’t separate leadership from nervous system health. Leaders who prioritize regulation see improvements in team morale, client trust, and long-term growth.

For anyone ready to lead with clarity and resilience, her book, “The Polyvagal Solution,” offers both the science and step-by-step methods to transform your nervous system into a valuable business asset.
