The first two posts in this series were about that angry little toddler in your head. The default mode network. The voice inside your head that is not really you.
That's the hard part to actually accept. Because at least for me, that internal dialogue always felt like who I was. It's the voice I hear when I read. The voice I hear when I think. I spent decades assuming that voice was me. It isn't. There's something underneath it: that breath, that moment of awareness that is more than just words and internal commentary.
The first two posts explored that. And if you've had any kind of trauma (most of us have, by the way: look up the ACEs test, Adverse Childhood Experiences, and see where you land), that early wiring runs deep and colors the dialogue you have with yourself for decades. One of the more sobering things I've come across is the idea that the way you talk to your kids becomes their internal dialogue later in life. Build them up. That's all I'll say about that.
Post one covered what the DMN is and why that voice isn't you. Post two covered what happens in your body when you finally get into the gap between stimulus and response, and why that gap is showing up in your physiology whether you're aware of it or not. (That's why when you're on my table and I tell you you've got a stressed pattern running, ninety-nine percent of you say "no I don't." Deny, deny, deny. Not just a river in Egypt.)
This post is practical. Here's how you actually break the loop.
When the DMN is running hot, your attention is stuck somewhere in the past or the future. Something you can't control or change. Forcing it back into the present moment short-circuits the loop. It collapses that threat simulation back into actual reality, and you become an observer again instead of a participant in a story your brain invented.
Name 5 things you can see right now. Actually look at them. Don't just name them. Notice textures, colors, the way light is hitting something specific.
Name 4 things you can physically feel. The weight of your feet on the floor. The temperature of the air. Whether the chair back is warm or cold. Something sweaty, maybe.
Name 3 things you can hear. Not just "traffic." Specific sounds. The pitch. The rhythm. Near or far.
Name 2 things you can smell.
Name 1 thing you can taste.
The whole thing takes ninety seconds, maybe two minutes if you're doing it right. By the end of it you're in your body and the DMN has quieted. It works because your attentional system cannot fully run a threat simulation and fully occupy present sensory experience at the same time. They compete for the same resources. Presence wins when you force the choice.
If you haven't read James Nestor's book Breath, read it. Everyone should read it. The physiology of breathing is wildly underappreciated and Nestor does a thorough job of making that case.
Box breathing is simple. Breathe in for a count of four. Hold for four. Breathe out for four. Hold for four. Repeat for five to ten cycles.
The exhale is the lever. It activates the parasympathetic nervous system through the vagus nerve. You are directly stimulating the brake system of your HPA axis. And the counting matters: it occupies the verbal processing channel the DMN uses to run its commentary. You cannot narrate a catastrophe while counting to four. Try it.
Do this when you first feel activated, not ten minutes into a spiral. The earlier you catch it, the less cortisol you're working against.
Garrett J. White is a maniac. I mean that in the most literal sense. And one of the things he figured out early on was that when he was in a full spin, the fastest way to break it was to drop and do burpees. Not because burpees are magical, but because they do something specific: they give your nervous system an actual physical threat to respond to.
Part of the problem is your DMN thinks you're being chased by a tiger when you're sitting in traffic. So give it a tiger. Ten burpees. Sprint up the stairs. Heart rate up, system responds, threat resolved, done. Your nervous system knows what to do with a real physical demand. It doesn't know what to do with an imaginary one on a continuous loop.
You don't have to do burpees. Cold water on your face activates the diving reflex and triggers immediate parasympathetic response. Thirty seconds on the face and wrists shifts your autonomic state faster than almost any cognitive approach. Grip something hard for a few seconds. Press your feet into the floor. Proprioceptive input grounds the nervous system in ways that thinking about grounding never does.
When you catch the voice doing its thing, name what it's doing. Not the content. The function.
"There's the voice catastrophizing about the news again." "There's the voice replaying that conversation from last week." "There's the voice comparing me to someone else."
There's a guy on Instagram I follow who has a similar approach to this. When someone says something rude, he recommends asking them directly: "Did you just call me an idiot?" Just naming it out loud breaks the automaticity. The same thing works internally. Name the voice. Not what it's saying, what it's doing. The DMN is powerful partly because it operates below conscious awareness. Surface it and it loses its grip.
The four tools above are acute interventions. They work better the more you've trained the underlying capacity.
Meditation works not because it relaxes you in the moment but because it builds attention span over time. You are literally training your prefrontal cortex to exert more regulatory influence over the DMN. Regular meditators show measurable structural brain changes. This isn't soft science.
If you've never meditated, start with an app. During the pandemic I used Headspace because it was free and I used it. It taught me more than I expected. I did a trial of 10% Happier and thought it did a better job of actual training. It was just more expensive than I was willing to commit to at the time. Both are worth trying. Both specifically teach you to find the gap between stimulus and response, which is exactly what this whole series is about.
Brain.fm is less meditation and more functional focus audio. It works well for my brain, especially on flights and for deep work. Breethe and Calm are solid options too. HeartMath does excellent work on getting coherence between the brain and heart, and I think that does a particularly good job of unplugging the DMN. The device costs money, but it's worth looking into. Muse lets you actually monitor your brainwaves in real time, which some people find useful for building awareness of their own states.
Ten minutes a day of any of these builds the muscle before you need it. When the toddler is mid-tantrum and cortisol is elevated, your attentional capacity is already compromised. You need the reps in before the crisis.
The most underrated intervention is what happens in the first forty-five minutes of your day, before the world gets a vote.
Garrett White's Core 4 protocol maps directly onto what we've been talking about across this whole series, so I'll describe it in those terms. There are four domains: body, being, balance, and business (and business here means the business of your life, not a company).
Start with the body. Get up and move. Ten pushups, ten squats, whatever gets your heart rate up and breaks a light sweat. You don't need forty-five minutes in a gym. You can do this in your underwear. The point is to give your nervous system a real physical demand before the DMN gets its first scroll of the morning. It tells your body something hard has already happened and it turns down the threat assessment.
Then fuel the body. Eat protein. Blood sugar stability is not optional here: every glucose crash activates your adrenals to compensate, which means every skipped breakfast is an HPA tax before 9am. Get protein and fat in before you leave.
Being is next. Sit down for ten minutes and breathe. Journal. Pray, if that's your thing. Write out your thoughts and have a conversation with whatever you understand God to be. Even if journaling is a conversation with yourself, the awareness underneath the internal dialogue counts. This is not productivity journaling. It's a nervous system drainage process.
Balance is last. Tell two people in your life what you honor, love, and appreciate about them. This sounds soft until you understand the neurochemistry. Genuine gratitude expression activates circuits that compete directly with threat-detection. You cannot simultaneously generate real appreciation and real threat response. They use the same resources. Then read something and learn something. Consume content that teaches you, then teach something to someone else. The learning keeps the prefrontal cortex engaged. The teaching grounds what you learned and keeps you in the role of someone contributing rather than someone the world is happening to.
The whole thing takes forty-five minutes if you're moving. What it does is set your nervous system before the DMN gets its first stimulus of the day.
Sometimes the tools above are not enough on their own. Not because they're ineffective, but because the underlying physiology has drifted far enough that the nervous system doesn't have the reserve to respond the way it should.
An old chiropractic mentor of mine used to make the distinction this way: what if it's not just that the hose is kinked? What if there's no water in it? You can remove every compression, correct every structural problem, and if the nervous system is chemically depleted, the information still doesn't move properly. Too much sugar, not enough protein to make neurotransmitters, pesticides, microbiome dysfunction, food toxins: it all adds up to a system that can't tolerate much and can't recover from anything.
That's where targeted support makes sense. These are lower-risk starting points, but your physiology is specific. What works at one stage of adrenal dysfunction may not work at another. Pay attention to how you respond.
ER 911 (NET Remedies) — Homeopathic acute stress support. Good for the moment the loop takes over. I recommend bookending breathwork with it: spray, breathe, spray again. Available at Doctor's Supplements using code JG6271.
Insomnitol (Designs for Health) — Sleep support. Along with the meditation apps, this is what got me through the pandemic. Short-term bridge only. If you're still needing it after four weeks, the underlying driver needs to be addressed.
NeuroMag (Designs for Health) — Magnesium L-threonate. Crosses the blood-brain barrier better than most magnesium forms. Helps cortisol regulation and sleep quality. Take it before bed.
Neurocalm (Designs for Health) — L-Theanine, GABA, B6, magnesium. For the wired-but-anxious state. It's a brake for an overactivated nervous system.
Things that need to be tested first: Catecholacalm, Adrenal Complex, Regenzyme Adrenal. These have glandular components and are targeted to specific stages of adrenal dysfunction. Using the wrong one at the wrong stage drives the dysfunction deeper, not better. Don't take them because they sound like a good idea.
One specific warning: ashwagandha is being recommended everywhere right now as a catch-all adaptogen for stress. It's a nightshade. If you have autoimmune issues or gut permeability, it can aggravate both. Get tested before you use it regardless of what the label says.
Your stress is your responsibility. Your brain is your responsibility. Your life is your responsibility.
Draw a circle around yourself. Deal with everything inside that circle. The nervous system can be regulated. Attentional capacity can be trained. And between every stimulus and every response, there is a space where your actual self lives.
These tools build access to that space.
Eat real food. Move your body. Address what's depleted. Stop letting a petulant internal toddler, running fear loops installed decades ago, make decisions for the adult you've become.
Nobody's coming. You're going to have to do it yourself.
If your nervous system doesn't respond to these tools the way it should, the underlying physiology may need evaluation. Dr. JJ Gregor assesses adrenal function and stress response at his Frisco, Texas practice. Schedule a consultation to find out what's driving the activation.
