How To Become Less Reactive & Cultivate A Deep Sense Of Calm with Jonny Miller #569

Jul 1, 2025 1h 51m 25 insights
Many of us are living with chronically dysregulated nervous systems, yet we mistake this reactive state for normal. Research suggests that our nervous system acts as a lens through which we experience reality. But when that lens is out of balance, we start to see threats where none exist – and respond in an exaggerated way to everyday situations. Today’s guest believes that by learning to work with our body’s innate wisdom, we can transform not just how we respond to stress, but how we experience life itself. Jonny Miller is the founder of Nervous System Mastery, a 5-week bootcamp where he has taught over a thousand students - from the CEO of a rocket-ship company and burned-out startup founders to busy parents and elite performers - how to cultivate calm, rewire reactivity and restore aliveness. After experiencing profound grief following the loss of his fiancée Sophie, Jonny embarked on a journey to understand how our nervous system shapes every aspect of our lived experience. During this incredible conversation, we discuss: Why anxiety isn’t actually an emotion, but a protective strategy used by the nervous system to shield us from deeper underlying feelings, and the difference between managing emotions and truly feeling them The three core skills of nervous system mastery: interoception (tuning into our internal world), self-regulation and emotional fluidity, and why developing these can transform every part of our lives How emotions themselves typically last just 10 - 20 seconds, but our resistance to feeling them creates what Jonny calls “emotional debt,” which can keep us stuck for weeks, months or even years Why working with the body (a bottom-up approach) can be more effective than trying to ‘think’ our way out of stress, and how it differs from cognitive strategies like reframing How practices like cold exposure can help train us to stop resisting discomfort and allow challenging sensations to move through us naturally Jonny’s reflections on grief are particularly moving. He shares how losing Sophie taught him that emotions – even the most painful ones – carry their own kind of wisdom. At its heart, this episode is about remembering what the body already knows. Jonny shows us that beneath our stress and reactivity lies a deep intelligence, and that when we learn to trust it, we can move through life with more presence, resilience and peace.

Actionable Insights

1. Develop Internal Sensitivity (Interoception)

Relearn to listen to the constant feedback from your body to regain sensitivity to your internal experience, which aids in decision-making and understanding your current state.

2. Cultivate Emotional Fluidity

Learn to welcome the full spectrum of human experience, recognizing that emotions themselves typically last only 10-20 seconds; resistance to feeling them creates prolonged suffering and “emotional debt.”

3. Reduce Reactivity’s Half-Life

Consciously work to shorten the duration you spend in reactive states (e.g., anger, frustration) from days to hours or minutes, enabling more intentional actions aligned with your values.

4. Prioritize Window of Tolerance

In challenging situations, especially conflict, focus on returning to a state where you feel grounded, present, and regulated, as productive engagement is difficult outside this “window of tolerance.”

5. Own Your Internal Responses

Understand that your emotional responses originate within you, rather than solely blaming external events. This shift in perspective empowers you to explore and process what is truly being triggered.

6. Process Emotional Debt

Avoid repeatedly suppressing emotional responses, as this accumulates “emotional debt” and “allostatic load,” which drains energy and reduces your capacity to handle stress.

7. Practice APE for Awareness

Train your “interoceptive palette” by regularly tuning into your Awareness (expansive vs. narrow), Posture, and Emotions/Sensations (e.g., feeling your feet on the floor) to upgrade your internal landscape.

8. Utilize Bottom-Up Downshifting Techniques

Employ physiological levers like humming (increases nitric oxide), long-hold stretches, or exhale-emphasized breathing (e.g., 4-7-8) to quickly shift your nervous system into a calmer, parasympathetic state.

9. Practice Mindful Cold Exposure

Use cold showers or plunges as an experiment to observe your body’s natural bracing response to discomfort. Practice relaxing and “letting the cold in” to train non-resistance, a skill applicable to emotions and life situations.

10. Complete Stress Responses (Impala Method)

Learn to discharge accumulated stress and intensity from your body through practices like breathwork, somatic surfing, or shaking, allowing the body’s innate intelligence to complete the emotional reflex arc.

11. Embrace Triggers with Curiosity

See anxiety or triggers as valuable “signposts” or invitations to courageously explore and understand what aspects of your experience you might still be protecting yourself from.

12. Be a Scientist of Experience

Actively experiment with different practices in your own life to verify their effects on your body and nervous system, rather than just intellectually consuming knowledge.

13. Set Boundaries for Rest

Actively protect and design periods of rest into your daily, weekly, and monthly schedule to counteract the modern world’s perpetual activation and prevent burnout.

14. Prioritize Deep Rest for Resilience

Train your resilience by practicing efficient downshifting from activated states using techniques like Non-Sleep Deep Rest (NSDR) or Yoga Nidra, ensuring deep recovery balances periods of high performance.

15. Daily Interoceptive Weather Report

Begin each day with a 5-minute internal check-in (before checking your phone) to notice your mind, awareness, posture, energy, emotional tone, and any sensations, gradually building internal awareness.

16. Identify Personal Somatic Markers

Become aware of your unique early warning signs (e.g., chest tension, stomach knots) that indicate you’re entering a reactive state, allowing you to intervene proactively.

17. Take Breaks During Conflict

If you notice yourself or your partner becoming reactive or leaving the “window of tolerance,” communicate the need to step away briefly to regulate before resuming the conversation.

18. Connect to Somatic Anger

When feeling anger, connect to the physical sensations (e.g., heat, tightness) and allow corresponding movements or sounds to express the energy, leading to a sense of relief and completion, rather than just looping on the story.

19. Reframe Anger as Boundary

Challenge the belief that anger is inherently bad. Instead, view “clean anger” as a healthy expression of clarity and determination used to set boundaries from a place of love.

20. Be Willing to Feel Grief

When experiencing grief, allow yourself to be “willing to be obliterated” by its intensity, trusting your body’s innate intelligence to process it. This can deepen your capacity for love and lead to raw aliveness.

21. Engage in Movement for Release

Utilize physical activity such as walking, running, or gym workouts to help complete partially unprocessed stress responses, contributing to improved mental and physical well-being.

22. Design Environment Intentionally

Consciously shape your physical surroundings (e.g., using noise-canceling headphones, choosing spaces with appropriate ceiling heights) to support desired states like relaxation, creativity, or focus.

23. Avoid Emotional Bypassing

Ensure that self-regulation practices (e.g., journaling, CBT, breathwork) are used to create safety and return to your “window of tolerance,” not to avoid or suppress underlying emotions.

24. Evaluate Caffeine Consumption

Be mindful that caffeine can numb interoceptive sensations and promote a stimulated state that may feel “safe.” Consider reducing intake if it’s used to push through fatigue or avoid deeper rest and emotional processing.

25. Practice Self-Unfoldment Mindset

Adopt a mindset of “self-unfoldment,” which involves welcoming and allowing whatever arises in your internal experience (e.g., tiredness, anger, sadness) without judgment or the belief that something needs fixing.
