How many people have a lot of stress in their lives? Everybody raises both hands and both legs.
Most of us think about resilience as a mental quality, something in the mind. We think if we could just think differently, reframe things more quickly, all developmental toughness will be able to handle stress and uncertainty without it wearing us down. But what if the most powerful tool for resilience isn't in your head at all? What if it's beating in your chest right now?
The heart-brain connection.
This is the next level of human evolution and consciousness. This heart intelligence needs to lead AI. The heart has its own intrinsic nervous system, a little brain in the heart. It has 40,000 sensory neurons. Every heartbeat puts out 2.5 watts of power. And you can think of the heart as a radio transmitter and receiver.
Is not focusing on the heart preventing us from actually getting the results?
If you just do it from the mind or willpower and the emotional system doesn't agree, it doesn't go very far. Just like trying to change a habit. You know, I'm going to diet.

Chapter 2: How does the heart-brain connection influence resilience?
Up here says, I'm going to diet. Down here says, no, I need my comfort food. You know, and you have a fight between the mind and the heart's knowingness.
My guest today has spent three decades at the forefront of research into one of the most underexplored frontiers in health and human performance, the heart-brain connection.
She's the president and co-CEO of HeartMath, an organization with over 500 independent studies validating its work, used by the Department of Defense, the VA, NASA, Stanford Medicine, Kaiser Permanente, and millions of individuals in over 100 countries.
Dr. Debra Rosman is a behavioral psychology, co-author of the Transforming Books series and Heart Intelligence, and one of the world's leading voices on heart coherence, heart rate variability, and the science of emotional resilience.
Her work has helped everyone from special force operators to burnt out healthcare workers to Olympic athletes learn to self-regulate their nervous system and transform the way they respond to stress on a biological level. Deborah, welcome to The Resilient Mind.
Thank you, Simba. I'm delighted to be here with you.
And we're excited to have you here. So, heart math has been around for over 30 years and has generated more than 400 independent studies. But it started somewhere. What was the original insight that launched all of this? And why did early heart math researchers discover, what did they discover about the heart that changed the way we understood what it actually does?
Great questions. Well, back in the late 80s, the founder of HeartMath, before it was called HeartMath, Doc Childry, had been doing research in the heart and the feelings of love and care and compassion and meditation and what works. We all enjoy those qualities of the heart or spirit.
And he wanted to create a simple user-friendly system based on research of how people could shift out of stress and activate those wonderful feelings that we all love to experience. That's what makes life worth living. And so I met him and I was... studying and teaching gestalt psychology and behavioral psychology.

Chapter 3: What role does heart rate variability play in emotional health?
and other leading researchers who were really also interested in what they call the problem of the heart. Because in brain research, they always screened out the signals coming from the heart because they were so strong. Instead, it was like, how do we look at these signals together? This was a very exciting time.
And fast forward to 1995, where the research on heart rhythm coherence, and I can explain that, actually was first published the first time we saw the connection between emotional state and our physical heart rhythms in the American Journal of Cardiology.
So that started research, creating training programs and techniques based upon the research results, doing pre and post assessments, outcome data in companies and hospitals with the U.S. military. Very much trying to see how we could create a simple user-friendly system for people to awaken and activate their hearts. Intuitive guidance and intelligence to resolve stress and anxiety.
foresaw in a vision how stress was going to increase tremendously. And this was in the 80s before the iPhone, before the internet. But with all this technological advancement he saw coming, we'd be so interconnected that until we learn how to connect in our hearts and get along with ourselves, let alone get along with each other, there was going to be tremendous stress and anxiety.
And he really wanted to create a simple science-based, research-based system of simple tools and techniques and technology that people could use to transform stress and anxiety and ride the waves of these tremendous changes he saw coming. And here we are in the middle of it all.
And so if we think about stress in the 80s versus the stress we are feeling or we're experiencing right now, is it fundamentally different?
It is fundamentally different and here's why. I'm sure your audience would love to understand this. In the 80s, when we would go, or 90s even, we'd go to different programs like we'd teach in our quality management programs at Motorola with the tools and techniques and technology we developed. We'd ask the audience, how many people have a lot of stress in their lives?
maybe two or three hands would go up in an audience of 50. You ask that now and everybody raises both hands and both legs. It's like, ah, help. And I have a lot of care and compassion for what it feels like to have accumulated stress, chronic stress. It's not like stress and then you recover and you find a way to ease things in the 80s unless you have a major life crisis like divorce or illness.
Now it's constant triggers, whether it's the news, whether it's what you read on social media or TV, and it triggers your stress response, or whether it's just the acceleration of change that your nervous system can't keep up with. And all of that creates an accumulation of stress energy in your system, and it through stress hormones. Cortisol builds up in the system and then it disrupts sleep.

Chapter 4: How can heart coherence enhance stress management?
And so we looked in the literature and fetal monitoring used what was called heart rate variability, which is looking at the beat to beat to beat changes in heart rate. And those changes changes in heart rate happen in every single beat. Your heart rate isn't like 65 beats per minute. That's an average. It's like 50 beats, 70 beats, 64, 84. And so it's got a pattern as those beat to beat changes.
That's why it's called heart rate variability. And that pattern creates a heart rhythm. And when we began to measure that blow away, we could see very sensitively how this heart rate variability responded to our thoughts and feelings. So when we feel frustrated, angry, upset, impatient, any of these stressful feelings
that we all experience from time to time, the heart rate variability or HRV gets very jagged and irregular, like riding your car with your foot on the brake and another foot on the accelerator. It's a herky-jerky ride and burns a lot of gas. The same with our body, our operating system.
When we let those stressful emotions cascade and continue, because they're meant for us to learn from, and I'll talk about that in a minute, but when we allow them to accumulate, it really creates what's called an incoherent waveform in that heart rate variability pattern over just a minute or two. And then of course it sustains for longer periods.
However, if we can learn how to shift that heart rhythm pattern, it shifts how we feel. Or if we shift how we feel in our attitude, it shifts the heart rhythm pattern. And that was amazing because that gives us a window into what's happening in the heart that is...
responding to our emotional system and actually creating a lot of the feelings we have because whatever that pattern is, the heart transmits it through the vagal nerve up to the brain and the head. And it goes to the amygdala, the emotional memory center and the thalamus, which synchronizes cortical function all the way to the frontal lobes.
So we have the window insight into when you feel stressful emotions, going to the amygdala and the thalamus, It triggers fight, flight, fright responses and survival responses. And it actually inhibits higher frontal lobe cortical function.
So that was blow away information that's been published in journals, respected journals like the American Journal of Cardiology way back in 1995, 96, 97, 20 years ago, but People don't know it yet, really. And we are at a point now where the world needs to know it.
And many, many more cardiologists, neurologists, psychologists, we have 95,000 certified heart math health professionals now who are utilizing this information and utilizing the heart math inner balance biofeedback, coherence biofeedback technology.

Chapter 5: What techniques can help activate heart intelligence?
That doesn't feel good, speeds up heart rate. When you are in coherence, that beautiful hills, you feel aligned. You feel harmonious. You feel at ease. Coherence in nature, physics, always implies harmony, order, just like a coherent discussion. Clarity. And that's exactly what this little brain in the heart signals to the brain in the head when your HRV is in this coherent rhythm.
So most of us, we think that if we are going to be resilient or manage our stress, we want to try to manage it from here. Maybe we might do some deep breaths and be like, okay, or positive thinking.
Right.
Is not focusing on the heart preventing us from actually getting the results or having sustainable results when we try to regulate our nervous system?
Right. If you just do it from the mind or willpower and the emotional system doesn't agree, it doesn't go very far. Just like trying to change a habit. You know, I'm going to diet. Up here says I'm going to diet. Down here says, no, I need my comfort food. You know, and you have a fight between the mind and the heart's knowingness, the heart's feelings.
What coherence does is it synchronizes heart, brain, and nervous system. So they're all aligned and entrained. And now you have more heart power and mind power to actualize your intentions. So it's really important to engage the heart. You can't ignore it. And you don't live from here up. We are a whole system.
And that's what the HeartMath techniques and tools provide, how you can do that and do it quickly. Because it's not a 20-minute meditation. It's a very simple way of going to the heart first, focusing in the heart, activating, say, a memory or a... feeling of appreciation or gratitude. That's one technique for anything, your pet.
You know, we teach children for chocolate chip cookies, whatever you love. And that changes the heart rhythm pattern. And then you can begin to have a conversation with your intentions because now the heart has engaged the mind. So the heart and mind working together, that's real resilience. I know you're called the resilient mind.
You've included the heart and then you have the resilient heart and the resilient mind. And you know what that does? It actually releases stored stress and anxiety. You feel uplifted. You rise above. Your now frontal lobes are seeing the bigger picture about the thing you were just stressed about. That is powerful.

Chapter 6: How does emotional flexibility contribute to overall well-being?
You change mood, you change perception, and you increase energy because your whole system is lined up. The energy can flow. That flow state is a powerful state for building resilience. as an energy that accumulates in your system. So then when the next stressor comes, you are at a different level in how you respond to it.
Your baseline is, I know where this is going to lead if I get angry or upset. Let me just stay calm and ride the wave. And you're able to do that. So resilience energy is so important. And you're building that capacity for that type of resilience with your nervous system harmony and your immune and hormonal system in balance.
So it's really important for people to understand that because we allow stress to accumulate because we don't have tools. We don't know what else to do. Nobody has given us either the science or the tools and technology to release stress as we go because we're all going to feel triggers at times. That's telling us. Relax. Go back to inner balance and calm. Go back to the heart. Breathe.
Almost every technique is in just mind. It also includes breathing. What we're saying, breathe at a six-second rhythm into the area of the heart. I mean, sorry, 10-second rhythm. In through the area of the heart, out through the area of the heart, about five in, five out, that six breaths a minute about. And that creates that smooth flow.
But to sustain it, that coherent rhythm, we have to have an elevated emotion or a positive feeling or attitude. That's why we say appreciation or gratitude is the easiest thing to shift into. But compassion, care, kindness, any of those genuinely felt will bring your heart rhythms into that coherence and sustain it with a carryover effect.
That has lasted six hours in terms of the immune and hormonal response. On the other hand... Five minutes of letting ourselves feel anger and rehash the thing that drives that stress response depresses the immune system for six hours.
Wow. Definitely something to think about. And for people who have had trauma, maybe PTSD, a chain of emotional injuries, or have just spent a long time just in an angry emotion.
Yes.
How quickly will these techniques work for them?

Chapter 7: What is the significance of global coherence in today's world?
It creates an anxiety habit. The amygdala is always kind of scanning for familiar, what's familiar. And so it re-triggers the PTSD or the anxiety memories, which is what it's designed to do. When you get into heart rhythm coherence, that coherent waveform is sent to the amygdala, which goes, okay, it has to build a new reference of this is when my system feels in balance, feels good.
And it starts to repattern the amygdala. So a lot of clinics, PTSD doctors, EMDR and other specialists for trauma actually are using heart math along with whatever methods. to change the communication from the heart to the amygdala, and that accelerates healing. We have a whole program at HeartMath called the Resilient Heart for trauma-informed therapies. And it's all these techniques and tools
that people can go to heartmath.com and find to be able to transform that frequency. And everything's energies and frequencies, but we're changing the pattern from heart to brain. And your question, how long does it take? Some people have experienced shifts, huge shifts of perception and release in a few days of practicing with heart rhythm coherence.
Some, it's a few months, but most people will have a neural habit change is what we call it in about six weeks of practicing heart rhythm coherence five to 10 minutes a day. That's incredible.
That is amazing. And thinking about coherence, the concept of heart rate variability has also become popular. Yes. The health metrics, performance tracking. But your system has got an important distinction where a lot of wearables will measure HRV, but HeartMath can actually train people to improve it.
Exactly. And there's a difference in what we measure. All those systems basically were born out of heart math, the wearables. Our research, we popularized heart rate variability biofeedback back in the early 90s when this research was published. In fact, Dr. Donald Singer was on our advisory board and he coined the term heart rate variability. He's also since deceased. He
All these other systems for recovery and how HRV can be measured as a number worn at the list, and you see a number and you want to increase your number, are measuring the amount of HRV, which is really important. So when I go these rolling hills, the amount is how high is the hill and how low does it go? Because we want that to be a lot. That is reflects resilience and recovery.
And we have the most of it when we're little kids, when we're babies, because we're very emotionally resilient. And then we lose it naturally as we go older, we get more emotionally habituated, more rigid, less flexible. This can keep you supple. It's great for the whole longevity anti-aging movement because you want to be emotionally youthful. And that's where coherence practice helps.
But we're not measuring amount because you can't do that co-pattern from the wrist. The wrist drops the interbeat interval so you don't get to see the heart rate change beat to beat to beat to beat and how that reflects your motions. That's why we have a sensor like this that connects to your ear, that connects to the app.

Chapter 8: How can listeners apply HeartMath techniques in their daily lives?
You know what to do when you get triggered. So you stop that energy drain. And you start with the power of the heart and the heart and brain, nervous system, coherent alignment. You build the energy of resilience and accumulate healthy hormones, healthy immune system. You're rebooting your system. I want everybody to have that symbol. I want everybody to have that power within them.
And what I love about your system is sometimes we work on a lot of things to manage our stress, make us feel healthy. But your system allows us to actually have a concrete value to see how we're doing. Because I know for myself, sometimes I think I'm doing good, I'm not stressed out, and then I end up snapping at something. Oh, I recently used your app as well. And I was like, oh, I feel good.
I feel good. But my coherence score was much lower than I anticipated. So I love that it gives that insight. And so we are not trying to guess, are you actually stressed out or not? You can actually see how your coherence is changing on a day by day basis. So we can actually intervene appropriately.
Right. Appropriate response. What you're doing there is you practice, and we'll all modulate, we're human, but you are increasing your baseline coherence, which is your baseline resilience, which means if we have you... hooked up to just be measuring your resting state coherence before you start training, which we do.
We have a whole lot of assessments we people and professionals can use or certified coaches and trainers can use. You're in a resting state and then you start practicing the five minute a day and then you start using the techniques when you're not using the technology so that you use them as you go.
They're meant to be used in the moment, not just when you're sitting there doing your five minute practice with the app. But okay, let me use this technique that got me into coherence and I developed the reference of what it feels like. Now let me use it when my wife yells at me or my kid does something that makes me upset or I watch the news and I'm ready to scream at the TV set.
Those are signals. Oops, let me not drain energy. Let me go back to balance, inner balance. That's what we call it, the inner balance coherence plus sensor. Let me go back to that autonomic balance because I'm going to have a bigger picture view, more mature approach. What's appropriate? Respond from that. As you increase your baseline coherence, you're more naturally in that state.
You're more naturally forgiving, kind, loving, caring, compassionate. Give people more latitude or have what we call business heart, more authentic communication. All of that is the real you. It's not something that you're plastic putting on. This is who you are at the core. This is allowing you to peel off the orange peel and get to the sweetness and the juice inside of who you are.
And that starts with the heart. It starts with your center of being, your core, and getting that feedback of when you're coherent and then using the techniques to come back to that through the day, six weeks. Nine weeks, we did a research study with 1,000 10th graders who were, we did their baseline resting HRV.
