The Ultimate Human with Gary Brecka - 303. The Truth About Anxiety and Your Vagus Nerve

Starting point is 00:00:00 You wake up exhausted no matter how much you sleep. Your heart races for no reason, and at night when you finally lay down, your body will not shut off. Does this sound familiar? That's a nervous system stuck in survival mode, and it's quietly breaking your body down while you're busy blaming yourself. Your autonomic nervous system is the part of your nervous system that runs in the background while you don't even think about it. It has two gears. The sympathetic branch? That's your gas pedal, fight or flight, and the parasympathetic branch.

Starting point is 00:00:26 That's your break, rest, digest, repair. And in the modern world, the doom scrolling, the caffeine at 3 p.m., the blue light at 11 p.m., that pedal never comes off the floor. Your body starts to believe that survival mode is normal mode. You make a new baseline, and now you're living your entire life in a low-grade state of fight or flight. This goes way beyond feeling bad. Chronically elevated cortisol is one of the most destructive forces in the human body. It suppresses your immune system. So while you're telling yourself, I'm just stressed, it's fine. Your body is keeping score. And what I'm about to share with you is going to completely change the way you look at your body. Because the fix isn't a pill.

Starting point is 00:01:02 The most powerful reset switch you own is... Your anxiety is not in your head. I know it's what you've been told your whole life, that it's mental, that it's a mindset problem, that you just need to think positive. It's not. It's in your nervous system. And I can prove it to you in the next nine minutes. You wake up exhausted no matter how much you sleep. Your heart races for no reason.

Starting point is 00:01:35 Your gut is a mess. You can't focus past two in the afternoon. and at night when you finally lay down, your body will not shut off, tired and wired. Does this sound familiar? That's not something you can just push through with willpower. That's a nervous system stuck in survival mode, and it's quietly breaking your body down while you're busy blaming yourself. I couldn't believe this when I first saw it in the lab data. How many healthy people are walking around in a low-grade state of fight or flight, 24 hours a day? And what I'm about to share with you is going to completely change the way you look at your body. Because the fix isn't a pill.

Starting point is 00:02:08 The most powerful reset switch you own is sitting right under your nose. You've been carrying it around your entire life. And when you stop using it correctly, everything just described starts happening. The fatigue, the anxiety, the gut issues, the brain fog, the accelerated aging. I'm going to show you how to flip that switch back with four things you can do before the sun goes down tonight. Welcome back to the ultimate human. I'm human biologist and biohacker Gary Breka. and I know that the human body is capable of extraordinary things if we just get out of its way.

Starting point is 00:02:40 So let's talk about what stuck in survival mode actually means, because this phrase is everywhere right now, but almost nobody explains it. Your autonomic nervous system is the part of your nervous system that runs in the background while you don't even think about it. It has two gears. The sympathetic branch, that's your gas pedal, fight or flight, and the parasympathetic branch. That's your break, rest, digest, repair.

Starting point is 00:03:03 That gas pedal was designed for short bursts. You see a predator. Your brain fires a signal to your adrenal glands, and they dump adrenaline and cortisol into your bloodstream, your heart rate spikes, your blood shunts away from your gut and into your muscles, and you run. It's a necessary system that saved your ancestors' lives from bears. But our brains cannot tell the difference between a bear

Starting point is 00:03:24 and a Microsoft Teams notification. It can't tell the difference between running from a lion and running late on a deadline. They activate the same sense. signal, release the same cortisol, and push the same gas pedal. And in the modern world, the emails, the doom scrolling, the caffeine at 3 p.m., the blue light at 11 p.m., that pedal never comes off the floor. Your body starts to believe that survival mode is normal mode. You make a new baseline, and now you're living your entire life in a low-grade state of fight or flight. This goes way

Starting point is 00:03:55 beyond feeling bad. Chronically elevated cortisol is one of the most destructive forces in the human body. It degrades your gut lining. It suppresses your immune system. It stores fat around your midsection. And the research on chronic stress and telomeres, the caps at the end of your chromosomes, suggest it's literally accelerating how fast you age. So while you're telling yourself, I'm just stressed, it's fine. Your body is keeping score. And so much of modern medicine is missing the point of my opinion. If you go to the doctor with these symptoms, you get seven minutes, a normal blood panel, you're handed a prescription for the symptom, something to sleep, something for anxiety, something for the gut. Nobody is asking the question underneath the question.

Starting point is 00:04:38 Why is your nervous system stuck in the on position? We're trying to turn off the smoke alarm instead of putting out the fire. If this sounds familiar to you, I want you to hear me. There's nothing wrong with you. Your nervous system is doing exactly what it was designed to do. It's just getting the wrong inputs. And here's the part that should give you real hope. If the end, created the state, changing the inputs can change the state. One more piece of science. Because I want you to understand the lever we're about to pull. Running from your brainstem down through your heart, your lungs, your gut is the vagus nerve, the master cabling of your parasympathetic nervous system. It's the physical brake line. And the best part is you can stimulate it manually.

Starting point is 00:05:20 You can literally reach in and pump that break. That's what the next four resets do. You ready? Reset number one. This is the fastest one, your breath. Breathing is the only autonomic function you can control consciously. So sit with that for a second. You can't decide how your heart rate beats. You can't decide your blood pressure, but you can decide your breath and your breath decides the rest. It's the remote control for your nervous system. Here's the mechanism. Short, shallow chest breaths tell your brain we're being chased. Long, slow exhales tell your brain the threat is gone. When you extend the exhale, you activate the vagus nerve. Your heart rate drops and your body down shifts in real time in about 90 seconds. The simplest tool I can give you is the physiological sigh.

Starting point is 00:06:10 Two inhales through the nose, one big one, and a second short sip at the top to pop open those air sacs in your lungs, then one slow exhale through the mouth all the way out emptying the tank, like this. Do that three to five times and feel what happens. Do five minutes of it every morning before you touch your phone. This is the switch I told you about at the top of the show. No prescription, no side effects. The most powerful nervous system medicine on planet Earth has been sitting right under your nose your entire life and nobody taught you how to use it. We actually recorded an episode with Wimhoff not too long ago and he has established the Wimhoff method. A resilience protocol built from many of the same pillars we're going

Starting point is 00:07:02 to discuss today. The cornerstone of it is breathwork. I highly recommend you check out that episode here. Reset number two is cold exposure. Now this one sounds backwards. So stay with me. Cold is a stressor. When you step into a cold shower, your sympathetic system fires. Adrenaline, nor adrenaline, the gasp, the racing heart. So why would I tell someone who's stuck in fight or flight to add more stress? Because of what happens next. When you stand in that cold and you slow your breathing down, long exhales, just like we talked about, you're teaching your nervous system how to find calm inside of stress. Every time you do it, your vagal break gets stronger. Scientists measure this as heart rate variability or HRV, and it's one of the best markers we have for a resilient nervous system.

Starting point is 00:07:47 Cold is a controlled stress that ends, and that's the lesson your body has been missing. Stress is supposed to end. Start simple. And your shower with 30 seconds of cold, work up to two or three minutes of cold, chin down, shoulders in, breathe long and slow on the exhale. When you can be calm and freezing water, that meeting, that traffic jam, that difficult conversation, they lose their grip on you. And reset number three, get outside within 30 minutes of waking and get sunlight directly into your eyes. Guys, I'm huge on this one. And if you've been following me for some time, I'm sure you've heard me talk about this. Remember that your cortisol is not the enemy. It runs on a daily rhythm. It's supposed to peak in the morning.

Starting point is 00:08:29 Get you up, get you moving, and taper down as the day goes on so melatonin can rise at night. When that rhythm works, you have energy in the morning and you sleep well at night. When that rhythm is broken, flat in the morning, spiking at 9 p.m., you get that tired and wired life. The master reset for that rhythm is morning sunlight hitting your retina. 10 minutes outside, no sunglasses, no window between you and the sky. That light anchors your circadian clock, and it tells every cell in your body what time it is. And while you're out there, take your shoes off. Put your very feet on the grass, the sand, the earth.

Starting point is 00:09:05 I know how it sounds, but we're electrical beings, and we spend our entire lives insulated from the surface of the earth. Sunlight in your eyes, feet on the ground, slow breathing, 10 minutes. That's the reset. Reset number four. Stop pouring gasoline on the fire. Two rules. First, caffeine. Caffeine has a half-life of about six hours.

Starting point is 00:09:27 That 3 p.m. coffee, half of it's still in your bloodstream at 9 p.m. Blocking the very receptors that tell your brain that it's tired in keeping your foot on that gas pedal. Cut it off by noon, 2 p.m. at the latest. Second, the last hour before bed is sacred. Dim the lights because bright blue light at night tells your brain it's noon and suppresses melatonin. Put the phone away because every scroll is a micro-hit of alert and assess.

Starting point is 00:09:53 cool dark room same bedtime every night your nervous system doesn't repair itself during the day it repairs itself in deep sleep so let's put it together morning sunlight bare feet five minutes of breath work in the shower 30 seconds of cold breathing slow afternoon last caffeine at noon latest 2 p.m at night dim lights no phone cool dark room notice what's not on that list there's no pill there's no $200 a month supplement stack. There's no app subscription. Every single one of these tools is free. It's ancient and it works with your biology instead of against it. This is the stuff that never gets a commercial because nobody can sell you the sun. And here's my challenge to you. Don't wait for Monday. Pick one. Just one and do it today. Do the physiological sigh right now. Before this episode even

Starting point is 00:10:43 ends, three breaths. Feel your body downshift. That feeling is proof you were never broken. Your nervous system just needed the right inputs. If this hits home for you, send this to the one person in your life who's living wired and tired. You know exactly who they are. This might be the reset they've been looking for, and that's just science.
