→ Become a Scientist of Your Own Life


// FOOD FOR THOUGHT

Welcome to the first edition of a new experiment... a meta-experiment, if you will.

Introducing The Sunday Experiment, our new regular newsletter format. Each Sunday, you'll receive a note from me, an experiment to run that day or throughout the week, and a few curated resources I've picked up along the way.

The core premise of what we share here is becoming a curious explorer of your internal landscape through simple experimentation.

I'm a firm believer in being a scientist of our own experience and moving through life from a place of curious exploration. Hopefully the experiments outlined here and in future weeks will empower you to keep learning and growing.

Let's dive in.

You're receiving this because you're an alumni of my flagship program, Nervous System Mastery. If you would prefer not to receive The Sunday Experiment, no problem. You can opt-out here.

Why You Keep Over-Reacting with Kelly Leveque

I was recently interviewed on the Be Well podcast by Kelly Leveque (listen or watch here). It's my first podcast appearance since becoming a dad, so you can expect insights on how early parenthood has stress-tested everything I teach.

We go deep on the human mechanics of emotion: why feelings are meant to move through the body rather than pool into "emotional debt," how to catch the early signs of dysregulation, and the simple breathwork + co-regulation practices that help you respond with more calm, presence, and connection.

"My kids are my biggest teacher. They press on my buttons and push on them relentlessly. And when I don't resist this, the aftermath is such a relief "

– Kelly LeVeque, Be Well

In this episode, you can expect to learn:

  • What "emotional debt" is, and how avoiding a feeling compounds the interest.
  • Why emotions are meant to move through the body, and how suppressing them creates more suffering.
  • The three levers of self-regulation: top-down, bottom-up, and outside-in, and when each is helpful.
  • Why intense breathwork like Wim Hof or Holotropic can backfire, especially for more sensitive people
  • How your kids, relationship and work are three arenas that reveal where you're still not free.
  • And plenty more, from grief and psychosomatic response to the pressures of entrepreneurship.

The Physiological Sigh

Downshifting from anxiousness, overwhelm, anger, and other forms of stress can be done anywhere and at any time.

Tip: Your nervous system self-regulates throughout the day using physiological sighs. Every time you naturally let out a deep exhale or ‘sigh,’ it's a sign that your body is downshifting or feels safe to relax.

Greetings! It's been a hot minute since I sent one of these.
