fluid, flexible, regulated. 00:05:12.240 --> 00:05:14.800 The nervous system can shift gears. 00:05:15.120 --> 00:05:18.240 Low HRV, it's stuck, mostly sympathetic. 00:05:18.399 --> 00:05:20.639 And that means your recovery is compromised. 00:05:20.800 --> 00:05:23.920 And this is where it starts to have negative impact on your health. 00:05:24.240 --> 00:05:28.000 I also introduced the term vagal tone in episode one. 00:05:28.319 --> 00:05:37.519 That's the activity level of your vagus nerve, the primary pathway of your parasympathetic system running from your brainstem through your heart, lungs, and gut. 00:05:37.759 --> 00:05:42.079 When the vagal tone is strong, your parasympathetic brake actually works. 00:05:42.319 --> 00:05:45.920 When it's weak, the accelerator dominates even at rest. 00:05:46.240 --> 00:06:03.759 So HRV is how we measure vagal tone objectively, which means HRV isn't just a wellness metric, it's a direct window into whether your nervous system's recovery capacity is actually functioning or just theoretically intact. 00:06:04.000 --> 00:06:06.240 And this is not a wellness fad. 00:06:06.560 --> 00:06:10.560 HRV has 40 years of clinical research behind it. 00:06:10.720 --> 00:06:19.279 It's used in cardiac rehabilitation, elite athletic performance, trauma recovery, and increasingly in preventative medicine. 00:06:19.439 --> 00:06:21.199 And that's where we sit. 00:06:21.439 --> 00:06:29.759 Now the fact that you can now access it on your wrist with a consumer device is relatively new and genuinely very useful. 00:06:30.240 --> 00:06:33.680 Okay, so now I want to bring this out of the abstract into something brilliant. 00:06:33.759 --> 00:06:37.279 So I want to talk about three people, three very different stories. 00:06:37.680 --> 00:06:43.279 In the last episode, I described three patients, all dysregulated, all missed by conventional medicine. 00:06:43.439 --> 00:06:46.800 So now I want to tell you what their HRV data looks like. 00:06:47.600 --> 00:06:51.680 The first is a high-performing professional in her early 30s. 00:06:51.839 --> 00:06:57.759 She looks fine on paper, she exercises regularly, has normal blood work, and occasionally meditates. 00:06:58.160 --> 00:07:03.920 But when you look at her HRV trend over eight weeks, it's moving in one direction. 00:07:04.079 --> 00:07:05.279 It's moving down. 00:07:05.600 --> 00:07:12.319 Her morning scores are chronically low, which tells us her nervous system isn't recovering overnight. 00:07:13.199 --> 00:07:17.680 What the data shows is what she can't fully feel yet. 00:07:18.079 --> 00:07:22.319 She is depleting faster than she's restoring every single week. 00:07:23.759 --> 00:07:29.839 Okay, the second patient is in perimenopause, late 40s, and her HRV is erratic. 00:07:30.079 --> 00:07:33.120 Some nights it's relatively good, most nights it's low. 00:07:33.360 --> 00:07:35.600 There's really no predictable pattern. 00:07:35.920 --> 00:07:39.360 So this maps directly

to what's happening hormonally. 00:07:40.000 --> 00:07:42.720 Estrogen actually supports vagal tone. 00:07:42.879 --> 00:07:47.680 It's one of the mechanisms through which hormone fluctuations affect how you feel. 00:07:48.000 --> 00:07:51.199 As estrogen levels shift, so does HRV. 00:07:51.360 --> 00:07:55.199 The data makes visible what labs can only partially explain. 00:07:55.360 --> 00:08:02.879 There are so many women that come into my clinic and they don't understand the stress that they're feeling. 00:08:03.120 --> 00:08:10.639 They're holding a lot of tension in their jaws and their upper shoulders, and um they they just don't understand what's going on. 00:08:10.720 --> 00:08:20.160 And when you go through the changes, um your baseline, once that estrogen starts to drop, your baseline cortisol levels go up. 00:08:20.480 --> 00:08:28.959 And that's why many women who are perimenopause, menopause, um, they feel more stress, but they don't, they don't understand. 00:08:29.040 --> 00:08:31.439 And they'll come into my clinic and just say something feels off. 00:08:31.519 --> 00:08:33.919 I don't know what it is, but something's not right. 00:08:34.240 --> 00:08:36.559 Okay, let's move on to the third patient. 00:08:36.799 --> 00:08:41.519 Um, the third patient is what I call system collapse. 00:08:41.840 --> 00:08:46.879 Mid-50s, decades of chronic stress, just pushing through everything. 00:08:47.120 --> 00:08:51.120 Her baseline HRV is chronically low and barely changes. 00:08:51.360 --> 00:08:57.600 The gap between her stress state and her recovered state has narrowed to almost nothing. 00:08:57.840 --> 00:09:01.679 Her nervous system has lost flexibility completely. 00:09:02.000 --> 00:09:05.200 And that kind of recovery requires more than rest. 00:09:05.440 --> 00:09:08.879 It requires consistent, structured support over time. 00:09:09.279 --> 00:09:11.039 That didn't happen overnight. 00:09:11.279 --> 00:09:18.720 This is a very different case than a young professional who just can't fully feel what the data shows, right? 00:09:18.799 --> 00:09:26.720 This is someone who has been in that state for decades, and all kinds of signs and symptoms start showing up at this point. 00:09:26.960 --> 00:09:28.159 So there you have it. 00:09:28.399 --> 00:09:32.639 Three different people, three different patterns, three different clinical pictures. 00:09:32.960 --> 00:09:39.360 HRV helps distinguish them, and that distinction changes what we do clinically, and that matters. 00:09:40.240 --> 00:09:42.480 Okay, so practical question here. 00:09:42.639 --> 00:09:44.639 How do you actually measure this? 00:09:44.879 --> 00:09:49.759 Well, you have several options at different levels of precision and cost. 00:09:50.240 --> 00:09:53.200 So the most common are consumer wearable. 00:09:53.360 --> 00:10:02.480 So it's the aura ring, whoop watch, or I'm sorry, the whoop band, Apple Watch, any kind of Garmin, chorus devices, those are all running watches. 00:10:02.639 --> 00:10:05.200 Um, all measure HRV overnight during sleep. 00:10:05.279 --> 00:10:10.559 And it does it at night because it's when the signal is the clearest, right? 00:10:10.639 --> 00:10:12.720 There's not all the noise happening during the day. 00:10:12.799 --> 00:10:14.559 So it's always measured at night. 00:10:14.879 --> 00:10:21.600 So they give you the trend and the data over time, which is more valuable than a single reading. 00:10:21.679 --> 00:10:23.600 And I'll tell you more about that in a second. 00:10:23.759 --> 00:10:30.879 But if you already own one of these devices, you probably have HRV data right now that you haven't looked at closely. 00:10:31.279 --> 00:10:42.639 Now, if you want something that is more accurate, um, the chest chest strap monitor, there is the Polar H10 paired with the HRV for training app. 00:10:42.960 --> 00:10:49.759 Um, this gets you research grade accuracy for morning readings and real-time data. 00:10:49.919 --> 00:10:55.440 So, this is what many clinicians and um I say serious athletes use. 00:10:55.519 --> 00:11:01.039 Um, so if you've ever seen a runner and they have that chest strap, that's that's what that's what they're measuring. 00:11:01.120 --> 00:11:02.240 That's what this is. 00:11:02.960 --> 00:11:07.519 And then there are dedicated biofeedback devices like the Heart Math Interbalance. 00:11:07.600 --> 00:11:10.639 It is the one I use with my patients in the coherence protocol. 00:11:10.799 --> 00:11:17.759 They don't just track HRV, they train you to shift, to shift it in real time through paced breathing. 00:11:17.840 --> 00:11:21.679 So I really um, I really like this little little device. 00:11:21.759 --> 00:11:22.559 It's fun. 00:11:23.039 --> 00:11:26.240 You can actually watch what's happening in real time. 00:11:26.320 --> 00:11:30.080 So you can watch your nervous system move from stress to calm on a screen. 00:11:30.240 --> 00:11:32.399 And that feedback loop is super powerful. 00:11:32.480 --> 00:11:35.759 So I really, really like this little little gadget. 00:11:36.559 --> 00:11:40.960 Okay, a few things worth knowing before you start tracking if that's something that you want to do. 00:11:41.039 --> 00:11:47.519 So, first, your HRV number is the most meaningful compared to your own baseline, not someone else's. 00:11:47.600 --> 00:11:49.279 It's very individualized. 00:11:49.440 --> 00:11:52.480 It depends on age, sex, fitness level, and genetics. 00:11:52.559 --> 00:11:54.879 It all influences where your number sits. 00:11:55.039 --> 00:12:05.679 So you have to do, you know, a week, a month, get your baseline, and then you can kind of monitor and see if you're going up or down. 00:12:05.840 --> 00:12:10.720 So don't compare your yourself to someone else's chart on the internet, okay? 00:12:10.879 --> 00:12:13.759 Um, compare yourself to yourself over time. 00:12:14.159 --> 00:12:17.919 Okay, second, a single reading tells you less than a trend. 00:12:18.000 -->

00:12:20.000 So what matters is the direction. 00:12:20.080 --> 00:12:25.440 Is your HRV improving over weeks, declining, staying flat despite your efforts? 00:12:25.679 --> 00:12:28.720 That's the information that you're you're looking for, okay? 00:12:28.960 --> 00:12:34.480 And then third, HRV drops acutely with alcohol, poor sleep, illness, and high stress week. 00:12:34.559 --> 00:12:35.679 So just remember that. 00:12:35.919 --> 00:12:40.480 Those uh dips are informative, they're not alarming, okay, guys. 00:12:40.639 --> 00:12:49.200 I've had people come into my clinic and they were just freaking out because their HRV had dropped and you know they were going through a really stressful time. 00:12:49.279 --> 00:12:50.559 So it will go back up. 00:12:50.720 --> 00:12:54.720 If you have a healthy system, you should be able to get that back up pretty quickly. 00:12:54.879 --> 00:12:57.360 So the system is just trying to tell you something. 00:12:57.440 --> 00:12:58.720 So just pay attention. 00:12:58.960 --> 00:13:04.320 And fourth, this is the most important thing I'll say about HRV, it can be trained. 00:13:04.559 --> 00:13:06.399 That's what you need to remember. 00:13:06.639 --> 00:13:10.240 Your baseline is not fixed, and that's the whole point. 00:13:10.559 --> 00:13:10.879 Okay. 00:13:11.919 --> 00:13:18.159 So if it can be trained, then what actually moves HRV, right? 00:13:18.240 --> 00:13:20.720 What builds that vagal tone over time? 00:13:21.200 --> 00:13:24.080 Well, one of the number one ways to do that is paced breathing. 00:13:24.159 --> 00:13:27.440 It's probably the most direct and accessible tool we have. 00:13:27.600 --> 00:13:37.200 And here's why it works: your vagus nerve, the primary highway of your parasympathetic system, actually passes through your diaphragm on your way to your abdomen. 00:13:37.519 --> 00:13:44.879 When you breathe slowly and deeply from the diaphragm, that movement mechanically stimulates the vagus nerve. 00:13:45.039 --> 00:13:50.080 And the exhale specifically is where the parasympathetic activation happens. 00:13:50.320 --> 00:13:55.600 Your heart rate slows, vagal tone increases, the break engages. 00:13:55.840 --> 00:14:01.200 Slowing your breath to roughly four to six breaths per minute amplifies this effect. 00:14:01.440 --> 00:14:05.519 Five to ten minutes of this moves HRV measurably. 00:14:05.759 --> 00:14:11.120 And you don't need a device, but having that biofeedback makes it faster to learn. 00:14:11.200 --> 00:14:14.240 And that's what we do in the coherence uh protocol. 00:14:14.480 --> 00:14:19.519 So the second tool, and I'll go deep into this in part three, is acupuncture. 00:14:19.759 --> 00:14:22.399 It works through a very similar pathway. 00:14:22.720 --> 00:14:26.639 You know, we've been treating the nervous system for thousands of years. 00:14:26.960 --> 00:14:37.919 But in more modern times, as we are in today, acupuncture has documented neurophysiological mechanisms for activating the vagus nerve and modulating the HPA axis. 00:14:38.080 --> 00:14:43.840 That's the hypothalmic pituitary adrenal axis, your central stress response system. 00:14:44.159 --> 00:14:49.759 And multiple studies show measurable HRV improvements following regular treatments. 00:14:49.840 --> 00:14:51.440 That's not a coincidence. 00:14:51.600 --> 00:14:55.279 It's the same system being addressed through a different entry point. 00:14:55.519 --> 00:15:02.480 Okay, now there's zone two cardio, that sustained conversational paced aerobic exercise. 00:15:02.639 --> 00:15:07.279 This builds cardiac fitness and increases your baseline HRV over time. 00:15:07.440 --> 00:15:10.879 Nothing fancy, walking, easy cycling, or swimming. 00:15:10.960 --> 00:15:11.279 Okay. 00:15:11.759 --> 00:15:17.200 Okay, another thing that you can do to improve your HRV is consistent sleep timing, right? 00:15:17.360 --> 00:15:22.480 So irregular sleep disrupts something called your circadium autonomic coupling. 00:15:22.799 --> 00:15:26.960 Basically, the coordination between your body's clock and the nervous system. 00:15:27.279 --> 00:15:29.039 Regularity restores it. 00:15:29.120 --> 00:15:35.519 So going to bed and waking at consistent times is one of the most underrated nervous system interventions there is. 00:15:35.759 --> 00:15:36.080 Okay. 00:15:37.200 --> 00:15:41.440 And lastly but not least are aptogenic and nervine herbs. 00:15:41.519 --> 00:15:45.440 So that's ashwagonda, rhodiola, raishi, and passion flower. 00:15:45.600 --> 00:15:50.879 Um, they all have solid research behind their effects on cortisol regulation and autonomic balance. 00:15:51.039 --> 00:16:00.559 So we'll cover this in more detail in part three as well when I talk about uh Chinese medicine and acupuncture for regulating the nervous system. 00:16:01.840 --> 00:16:10.639 Okay, so there are some ways that you can start today to start uh increasing your HRV, and none of these require a device. 00:16:10.960 --> 00:16:19.200 Um, but the devices are fun because it does show you which one of these are working the best for you and how much. 00:16:19.919 --> 00:16:22.159 That feedback changes behavior. 00:16:22.480 --> 00:16:28.159 People do the work when they can see it's working, and that's not a small thing. 00:16:28.480 --> 00:16:41.440 Okay, so before we wrap it up here, I I just want to talk a little bit about the coherence program that I have developed and the connection. 00:16:41.679 --> 00:16:47.840 So when I designed the coherence protocol, HRV tracking was a non-negotiable for me. 00:16:48.000 --> 00:16:53.120 Not because tracking is the point, and I don't want people to get obsessed about it, but because it closes the loop. 00:16:53.360 --> 00:16:55.759 Without measurement, we're guessing. 00:16:56.000 --> 00:16:59.519 With it, we can see the nervous system responding. 00:16:59.919 --> 00:17:04.720 We can adjust the protocol based on data, we can document recovery. 00:17:04.880

--> 00:17:09.119 Patients can feel improvement subjectively and see objectively. 00:17:09.440 --> 00:17:13.759 For people who've spent years being told their labs are normal while feeling terrible. 00:17:14.000 --> 00:17:19.920 That visibility, tracked evidence of change is often the most validating part of the entire process. 00:17:20.079 --> 00:17:24.640 But there's another layer to the biofeedback work that I think is equally important. 00:17:25.200 --> 00:17:29.359 The device doesn't just show you data, it trains you to feel it. 00:17:29.599 --> 00:17:41.279 Over time, patients start to recognize what regulation actually feels like in their body, not just as a number on a screen, but as a lived, embodied experience. 00:17:41.519 --> 00:17:45.839 And that matters enormously when we're trying to create lasting change. 00:17:46.160 --> 00:17:52.559 Because real change, the kind that sticks, requires your mind, body, and your emotions to be working together. 00:17:52.799 --> 00:18:06.000 Not just knowing intellectually that your nervous system is dysregulated, actually feeling the difference between a regulated and dysregulated state and being able to move toward regulation intentionally. 00:18:06.480 --> 00:18:08.319 That's what I'm building here. 00:18:08.480 --> 00:18:12.559 Biofeedback is the bridge between data and embodiment. 00:18:12.880 --> 00:18:26.480 The 12-week program includes HRV baseline assessment at the start, biofeedback instruction and the first few sessions, trend monitoring throughout, and formal reassessment at midpoint and at close. 00:18:26.720 --> 00:18:28.799 The invisible becomes visible. 00:18:29.119 --> 00:18:34.640 Progress is documented, and when something isn't working, we know it quickly and we adjust. 00:18:34.880 --> 00:18:40.720 So right now I have a primary cohort that is limited to 10 patients. 00:18:40.960 --> 00:18:42.799 I already have some on board. 00:18:56.319 --> 00:19:08.240 So if what we're covering in this series is landing for you, if you recognize yourself in any of these patient stories, the link to learn more about the coherence protocol is in the show notes. 00:19:08.319 --> 00:19:10.240 So no pressure, just information. 00:19:10.480 --> 00:19:14.880 The consultation is where we figure out together whether it's a good uh fit for you. 00:19:14.960 --> 00:19:16.960 So it is a complimentary consultation. 00:19:17.039 --> 00:19:21.039 You just gotta get online, fill out the form, and then I'll reach out to you, okay? 00:19:21.279 --> 00:19:25.279 All right, well, let's wrap this up and bring this episode together. 00:19:25.599 --> 00:19:29.440 HRV is the clearest window we have into nervous system function. 00:19:29.599 --> 00:19:38.319 It's not a wellness trend, it's a validated biomarker that tells you what your stress level, your sleep quality, and your symptoms can only hint at. 00:19:38.559 --> 00:19:40.000 And that's trainable. 00:19:40.240 --> 00:19:53.119 If your HRV trend is moving in the

wrong direction, despite your best efforts, if the trend is flat or declining and you're not sure why, that's the signal that something more structured and consistent is needed. 00:19:53.440 --> 00:19:58.400 Data without intervention doesn't change anything, it probably just stretches you out more. 00:19:58.640 --> 00:20:00.160 Um, just one last story. 00:20:00.319 --> 00:20:10.000 I was at the gym and I was talking to someone about the aura ring, and um, she made the comment that she felt like uh the data was really great. 00:20:10.079 --> 00:20:14.880 Uh, but she looked at me and she goes, but I don't know what to do with it, but it's cool. 00:20:15.119 --> 00:20:18.799 So again, data without intervention, it doesn't change anything. 00:20:19.039 --> 00:20:26.720 Okay, well, I hope you join us for part three because we are going into acupuncture and herbal medicine through the lens of nervous system science. 00:20:26.960 --> 00:20:36.559 How these modalities work neurophysiologically, what research actually shows, and how they interact with the autonomic regulation we've been talking about here. 00:20:36.799 --> 00:20:42.160 And I'm also going to throw in some Chinese medicine uh uh theory along with that. 00:20:42.240 --> 00:20:43.599 So it'll be super fun. 00:20:44.079 --> 00:20:46.720 And I'm excited to put it together for you. 00:20:46.960 --> 00:20:48.400 So thank you so much for being here. 00:20:48.559 --> 00:20:52.559 If this episode was useful, share it with someone who needs to hear it. 00:20:52.880 --> 00:20:54.559 Also leave a review if you have a minute. 00:20:54.720 --> 00:20:56.880 It genuinely helps other people find the show. 00:20:57.039 --> 00:20:58.880 All right, well, I'm Sherry Davidson. 00:20:59.039 --> 00:21:06.240 You can find me at Element5, Acupuncture and Wellness, and you can find the Wellness Inspired Podcast wherever you're listening right now. 00:21:06.480 --> 00:21:11.279 All right, well, take a care of your nervous system, and I'll talk to you in the next one. 00:21:11.519 --> 00:21:12.160 Bye. 00:21:22.000 --> 00:21:26.720 If you like what you hear, please subscribe to the podcast and share with your family and friends. 00:21:26.880 --> 00:21:30.400 You can also give me a rating and review wherever you listen to your podcast. 00:21:30.559 --> 00:21:32.319 It helps others find me as well. 00:21:32.480 --> 00:21:38.799 To get updates on new episodes and wellness inspiration in your inbox, please join the wellness inspired community. 00:21:38.960 --> 00:21:42.400 Go to the wellness inspired podcast.com to sign up. 00:21:42.559 --> 00:21:45.920 I'll put the link to the website in the show notes so you can click and join. 00:21:46.160 --> 00:21:53.519 Also, there's a Facebook community at the Wellness Inspired, and you can follow me on Instagram at wellness underscoreinspired. 00:21:53.759 --> 00:22:02.720 If you're in the Houston area or just visiting and interested in our services, acupuncture, herbal medicine, cupping, zinchiatsu, or dry needling therapy, contact us. 00:22:02.880 --> 00:22:06.799 You can find out more on our website at element5om.com. 00:22:06.960 --> 00:22:10.240 That's element5thenumber5om.com. 00:22:10.400 --> 00:22:12.720 And again, I'll put the link in the show notes. 00:22:12.880 --> 00:22:17.119 If you're interested in health and wellness coaching, we can connect in the clinic or on Zoom. 00:22:17.279 --> 00:22:19.839 Reach out to us and we'll get you on the schedule. 00:22:20.000 --> 00:22:22.480 And as always, I would love to hear your feedback. 00:22:22.640 --> 00:22:28.640 I am dedicated to bringing you great content that is inspiring and informative with an artsy fun edgy spin. 00:22:28.880 --> 00:22:30.240 Thank you so much for listening. 00:22:30.400 --> 00:22:31.920 We'll meet here again next time. 00:22:32.079 --> 00:22:36.240 And remember, never stop exploring, learning, loving, and being you. 00:22:36.559 --> 00:22:37.200 Bye.
