Afferent Neurons Outnumber Efferent Neurons Four to One
“And there's four times more afferent neurons going from the body to the brain as from the brain to the body.”
Miller: Somatic Regulation Works Better Than Cognitive Reframing
“Instead of kind of trying to change the story, or trying to fix something, or trying to solve something, which is what, you know, most people do by default, myself included in the past, if you change your state first, then there's a cascading effect which chan…”
How Breathing Ratios Act as Nervous System Levers
“And so what scientists have discovered that when the exhale is twice as long as the inhale, it has a calming effect. And when the inhale is either more intense or twice as long as the exhale, it has an activating effect.”
Lenny Gets Nervous Before Every Podcast Episode
“I get nervous before every podcast. Like, this is not my natural state.”
Miller: Breathwork Works Faster and Better Than Meditation
“People say mindfulness, meditation, things like that, that, that can increase the psychological space between stimulus and response. And that is something that Obviously does help over the long term, but it's in my opinion, no nowhere near as kind of rapid and…”
Humming Releases Nitric Oxide and Reduces Eye Fatigue
“I note on the humming, it also releases nitric oxide, which is a vasodilator, and that helps to create that kind of calming effect, and it also reduces eye tension as well, so I'll do it if I've been looking at a screen for too long. It's really good for kind …”
Spontaneous Sighing Means Your Body Is Downshifting
“I'd also add that the sigh happens naturally as a result of doing these downshifting practices. So if you notice after you do, let's say the four four eight breathing, at the end you might naturally just want to let out a sigh and that's a signal that your bod…”
Why Rapid Mouth Breathing Overwhelms the Nervous System
“I like to keep it through the nose only, because if you do it through the mouth, it can be Very, you know, too activating, and it can kind of overwhelm people.”
Somatic Tools Fail in the Moment Without Daily Practice
“Usually the challenge is that when someone is kind of in that like flustered state, remembering to do the practice is often the last thing that comes to mind. So by kind of having a deliberate practice for, you know, at least kind of seven to 10 days, And so t…”
How Somatic Practices Can Intercept Panic Attacks Early
“Certainly a panic attack doesn't come out of nowhere. There will be a kind of cascade of subtle things that happen in your body that eventually result in, in anxiety. And so if you can catch those things early and kind of like nip them in the bud and do one of…”
ADHD and PTSD Correlate With Low Interoception
“ADHD tends to correlate with low levels of interoception, as does if people have PTSD or trauma, again, interoception is lowered.”
Wall Street Traders With High Interoception Make More Money
“I was also reading a book recently called The Hour Between Dog and Wolf, which looked at Wall Street traders, and they correlated higher degrees of interception with basically making more money and making better decisions.”
Email Apnea: Unconsciously Holding Your Breath Checking Inboxes
“When people are checking their emails, they will, without noticing it, start to hold their breath, which is generally a very activating thing to do.”
Burnout Progresses From Feathers to Bricks to Dump Trucks
“Yeah, so I have this idea that I call the feather brick dump truck phenomenon, and basically what that means is when we are showing early signs of burnout, our body will give us feedback, usually in subtle ways in the beginning. So the feather might be waking …”
How Incomplete Stress Cycles Store Emotional Debt
“Yeah, so I'll tie this in with a concept that I call emotional debt, which is basically when our nervous system experiences stress, there's what's known as a mobilization cycle, and if that cycle isn't completed or we don't get to downshift or relax on the oth…”
Needing Wine to Unwind Signals High Emotional Debt
“What one really key sign actually is if you're not able to kind of naturally downshift or downregulate your nervous system at the end of a day without something like wine or CBD or some kind of like external substance, that's a sign that you're, you kind of re…”
Miller: Talk Therapy Fails to Resolve Nervous System Stress
“I'm not a big fan of talk therapy alone, or at least therapy that doesn't have a somatic or body-based component. And from my understanding of the nervous system and how we store this stress, just talking about things and keeping things on the level of the int…”
How to Pay Off Emotional Debt Somatically
“By tracking the somatic markers and then either on your own, just kind of following that sensation and allowing whatever emotion was present at the time to complete, that is the way that we kind of by, we slowly pay off that emotional debt by like one process …”
Why We Can't Make Decisions Without Emotion
“There was a landmark study by this guy, DiMazio, who's this kind of famous neuroscientist, and he studied a patient called Elliot, and Elliot had a tumor in his brain that was removed, and it basically meant that he was unable to feel emotions. So his entire e…”
Fear of Feeling Emotions Skews Subconscious Decision-Making
“If they are avoiding feeling a certain way, let's say that they don't enjoy feeling conflict or anger, then they will make decisions subconsciously to avoid feeling that way. And it becomes, you know, a huge bias and a huge problem because people make decision…”
Miller: Cortisol Acts as a Bodily Numbing Agent
“When there's cortisol present in our body, the cortisol basically acts as a numbing agent. So it's much harder to kind of tune into those sensations”
A Strong Work Ethic Requires an Equal Rest Ethic
“If you have a great work ethic that needs to be matched with a great rest ethic. And I think that, that kind of piece of actually training our capacity to downshift after stress Is just completely missing from most people's playbooks.”
How Somatic Breathwork Lowered Jonny Miller's Vocal Pitch
“Like if you listen to the podcast episodes I recorded four or five years ago, my voice is, is higher pitched. It's like it's, It just sounds different. It has, like, a different resonant quality to it.”
NSDR Doubles as a 15-Minute Interoception Practice
“And if you do the NSDR, that is basically a 15 minute interoception practice as well. So you're kind of getting two birds with one stone. With that practice.”
Miller: Trauma Lives in Cortical Maps, Not Physical Tissues
“It's not strictly true to say that the trauma is in the body. There's actually a cortical map in the brain, which kind of tracks these things, but for kind of practical purposes, it looks and feels as if there is stored grief in my right hip or anger in my sol…”
Survey: Burnout Costs Startups a Median of $100,000

Asking How You Are Complicit Reveals Subconscious Sabotage
“How are you complicit in creating the conditions that you say you don't want, and so the word complicit there is key because it's not saying, like, in what ways is it your fault, but it's like, in what ways were you complicit in creating the conditions for anx…”
