Rewiring the Brain - Overcoming Negativity Bias 
and Cultivating a Positive Reality

When I guide people through breathwork sessions, I often watch their faces transform as they shift from tension to relaxation, from vigilance to openness. What's happening in those moments isn't just psychological—it's a profound neurobiological shift from ancient fear circuits to expanded awareness. This is the journey from survival to creation that I've witnessed thousands of times, and one you can experience too.

The Ancient Origins of Negativity Bias

Take a deep breath and imagine yourself as one of our early ancestors, walking through tall grass, every sense alert for danger. That vigilance—that constant scanning for threats—is still with us today.

The negativity bias evolved hundreds of millions of years ago when missing a predator meant death, while missing a meal just meant temporary hunger. Our primitive nervous systems prioritized threat detection, and our amygdala—the brain's fear-processing center—developed to react instantly to danger and store negative experiences more vividly than positive ones.

I often ask my clients: "How much of your day is spent responding to perceived threats versus actively creating what you want?" Most realize they're still running ancient survival software in a world where true threats are rare.

Spirituality as an Evolutionary Adaptation

During a recent breathwork circle, Sarah, a corporate executive, had a profound realization: "I've been living my whole life braced for impact." After 20 minutes of conscious breathing, she accessed something beyond her fear—a sense of spaciousness and connection that reduced her anxiety more than years of medication.

This access to expanded awareness is no accident. Spirituality evolved as a cognitive mechanism to guide perception beyond fear-driven instincts. While the amygdala keeps us in survival mode, spiritual practices activate the prefrontal cortex—responsible for rational thought, higher awareness, and vision.

When we engage in breathwork or vocal toning, we're not just relaxing—we're participating in the evolution of human consciousness from reactivity to creativity.

The Amygdala's Role in Perception & Negativity Bias

I invite you to try this simple but powerful exercise right now: Place your hand on your chest and notice your breathing pattern. Is it shallow and quick in your upper chest, or deep and slow in your belly?

Without realizing it, many of us breathe in patterns that signal danger to our nervous system.

The amygdala processes negative information faster than positive stimuli, amplifies perceived threats, and maintains constant vigilance—even in safe environments. It works with the pituitary gland to release stress hormones and can suppress the pineal gland, which is associated with higher states of awareness.

When a client tells me they can't stop worrying, I explain that their amygdala is simply doing its ancient job. The problem isn't the fear response—it's that this response has taken control of their perception.

How to Rewire the Brain & Reduce the Amygdala's Influence

The wonderful news—which I've seen confirmed countless times in my practice—is that while negativity bias is hardwired, the brain is remarkably plastic. Here are practices I've found most transformative:

1. Meditation & Mindfulness (Direct Amygdala Shrinkage)

James, a veteran with PTSD, started with just 3 minutes of daily meditation. "I couldn't sit still for longer than that," he told me. After six weeks, he noticed he was responding rather than reacting to triggers. The science confirms his experience—studies show 8 weeks of mindfulness meditation actually reduces amygdala size.

Practice: Try this 5-minute reset: Sit comfortably, focus on your natural breath, and when your mind wanders (which it will!), gently return to the sensation of breathing. Even this simple practice begins to shift control from the amygdala to the prefrontal cortex.

2. Cold Exposure & Breathwork (Rewiring Fear Responses)

The first time I guided a group through Wim Hof breathing followed by an ice bath, I was amazed at the transformation. People emerged with bright eyes and peaceful expressions, describing sensations of clarity and joy.

When we deliberately expose ourselves to manageable stress (like cold) while maintaining calm breathing, we literally rewire our stress response system. The amygdala learns: "This is uncomfortable but not dangerous."

Practice: Start your shower at a comfortable temperature, then gradually turn it cooler for the final 30 seconds. While in the cold water, breathe slowly and deeply. Notice the initial panic response, then feel how your conscious breathing creates calm despite the discomfort.

3. Neuro plasticity: Training the Brain for Positivity Bias

One of my favourite vocal practices is "tone and groan"—we make low, vibrating sounds expressing discomfort, then shift to open, resonant tones of relief and joy. Participants often laugh at the dramatic shift in their emotional state from just two minutes of vocalization.

Practice: Each morning, place your hand on your heart and speak aloud three things you're grateful for. Feel the vibration of your voice in your chest as you say them. This simple practice activates neural pathways of appreciation and signals safety to your nervous system.

4. Activating the Pineal Gland (Higher Perception)

In darkness meditation retreats, I've witnessed people access extraordinary states of creativity and insight. One artist who had been blocked for years suddenly "saw" an entire series of work during a 30-minute darkness meditation.

When the amygdala is calm, the pineal gland becomes more active, enhancing intuition and expanded awareness.

Practice: Try this "darkness bath" tonight: Sit in complete darkness for 10 minutes before bed (or use an eye mask). Place your hands over your heart, breathe deeply, and make a gentle humming sound on the exhale. This combination calms the amygdala and stimulates pineal function.

Final Thoughts: From Negativity Bias to Positivity Bias

We are no longer hunter-gatherers fighting for survival, yet our brains still operate as if we are. This outdated wiring fuels cycles of anxiety, division, and conflict. The mechanism is simple: what we focus on, we reinforce.

I've seen people transform decades of anxiety through these practices. The shift isn't just personal—it's collective. When we choose to regulate our nervous systems and expand our perception beyond fear, we contribute to a more conscious humanity.

Rewiring our perception isn't just personal growth—it's an evolutionary imperative. By shifting from fear to clarity, from survival to creation, we stop reinforcing a world of division and scarcity and start building a world shaped by conscious intention, cooperation, and abundance.

I invite you to begin right now with one conscious breath. Feel your feet on the ground, let your breath deepen, and notice how quickly perception can shift from constriction to expansion. This is the journey we're on together.
