Latest / The Burnout Podcast with Fexingo: Workplace Exhaustion, Recovery, and Sustainable Careers / How Your Nervous System Fuels Career Burnout
Transcript
- Lucas: So I want to start with a weird thing that happened to me last week. I'm sitting at my desk, it's a Tuesday at like 3 PM, and I realize my jaw is clenched so hard my temples ache. I had no idea. I wasn't angry, I wasn't stressed about a deadline. I was just… existing. But my body was acting like I was about to be attacked. Luna: That is such a familiar feeling. And it's not just a tension thing, right? That kind of chronic low-level activation is actually what drives a lot of career burnout — and most of us don't even notice it until we're wrecked. Lucas: Exactly. And what I've been digging into is the science behind that. It's not just 'stress' in the vague sense. It's your autonomic nervous system — the part of you that runs your heart rate, your digestion, your fight or flight response — getting stuck in the wrong gear. Luna: I've read a bit about polyvagal theory — is that what you're talking about? The work of Stephen Porges? Lucas: That's exactly it. Stephen Porges, a neuroscientist, developed polyvagal theory in the 1990s. And the core idea is brilliantly simple: your nervous system has three main states. There's the ventral vagal state — that's your 'social engagement' mode, when you feel safe, connected, calm but alert. Then there's the sympathetic state — fight or flight, mobilization, the gas pedal. And then there's the dorsal vagal state — that's the 'freeze' or shutdown response, like when an animal plays dead. Luna: And you're saying that chronic burnout keeps people stuck between sympathetic and dorsal — like revving the engine and then collapsing? Lucas: Exactly. Most people think burnout is purely about working too hard. But the real mechanism is that your nervous system spends too much time in a state of perceived threat. Your amygdala — the threat detector — keeps lighting up because of an aggressive email, a tight deadline, a micromanaging boss, even just the constant ping of Slack. So your body stays in low-grade sympathetic activation. Luna: And that depletes your resources — like, you're running a constant metabolic cost. Eventually, you slide into dorsal shutdown — the fog, the exhaustion, the emotional flatness. That's the burnout that feels like 'I can't care anymore.' Lucas: Right. And here's what I found so freeing about this framework: it reframes burnout from a character flaw — 'I'm not tough enough' — to a physiological response. Your body is doing exactly what it's designed to do. It's just getting the wrong signal. Luna: So the question becomes: how do we signal safety to our nervous system? Especially in a workplace that's designed to keep us in that sympathetic state? Lucas: That's the million-dollar question. Porges talks about something called 'neuroception' — the subconscious process where your nervous system is constantly scanning for cues of safety or danger. And the really interesting thing is, those cues are often social. A warm tone of voice, eye contact, a genuine smile — those signal safety to the ventral vagal system. But most of our work interactions are the opposite: staring at screens, reading typed messages with no vocal warmth, or being in meetings where people are tense. Luna: So the fix isn't just 'take more breaks.' It's about what you do during those breaks that actually flips that switch. Like, closing your eyes for two minutes isn't enough if your nervous system is still braced for the next email. Lucas: Totally. One of the most effective tools I've found is something called the 'physiological sigh' — a double inhale through the nose, then a long exhale through the mouth. It's actually a natural way to reset the autonomic nervous system. Your lungs have these tiny air sacs called alveoli that can collapse under stress, and that double inhale reinflates them, which signals your brain that you're safe enough to breathe deeply. Luna: I've tried that! It's weirdly effective. I use it between client calls — just one or two of those sighs, and I feel my shoulders drop. But I have to remember to do it. Lucas: And that's the challenge — we forget because our nervous system is so habituated to the threat state. So I set a timer on my phone every 45 minutes. It's not a break to check social media; it's literally a 60-second reset where I do one physiological sigh, then I look out the window — not at a screen — and I try to notice something with a soft gaze. Luna: Soft gaze — that's a ventral vagal cue too, right? In polyvagal terms, the muscles around your eyes relax when you're in social engagement mode. So staring intently at a screen is actually a sympathetic cue — it's like your eyes are saying 'I'm hunting for prey.' Lucas: Ha, exactly. My wife actually tells me I look 'scary' when I'm deep in focus — my eyes narrow, my jaw tightens. And I'm not angry, I'm just in sympathetic drive. So part of recovery is retraining those micro-cues. Another big one is vocal tone. If you're on a call, try consciously lowering your pitch a little and speaking more slowly. That signals safety to both you and the other person. Luna: I've noticed that when I do that, my own heart rate slows. It's almost like we can hack our nervous system through our behavior. But I want to ask: what about people who work alone, or remotely, and don't have those social cues? Like, what if you're a freelancer in a quiet apartment all day? Lucas: That's a great point. For solo workers, the social cue can come from something as simple as a brief video call with a friend, or even listening to a recording of someone's voice that feels warm. There's also evidence that humming or singing — because it stimulates the vagus nerve — can shift you toward ventral vagal. So humming while you wash dishes after lunch? That's a recovery practice. Luna: I love that — it's so low-barrier. And it makes me think about how many of our 'recovery' recommendations — like meditation apps or yoga — actually require a certain level of nervous system regulation to begin with. If you're in dorsal shutdown, sitting still in meditation can actually make you feel worse because you're just sitting with the shutdown. Lucas: Yes! That's a key insight. If you're in dorsal vagal — the freeze state — you need active, mobilizing recovery first. Something like a brisk walk, shaking your hands and arms, even jumping jacks. That's actually a more effective reset than trying to force yourself to be still. The idea is to move up the ladder: from dorsal to sympathetic, then from sympathetic to ventral. Luna: So you have to match the recovery to which state you're in. And most people don't even know which state they're in. Lucas: Exactly. So here's a simple check-in I use: I ask myself, 'Do I feel like running away, or do I feel like hiding?' If it's the first, I'm sympathetic — I need to exhale, slow down, orient to safety. If it's hiding, I'm dorsal — I need to move, shake, get my blood flowing. And if I feel no strong urge either way, I might actually be in ventral, which is where we want to be. Luna: That is incredibly practical. I'm going to start using that. And it also reframes a lot of the classic burnout advice. Like, 'take a bath' is great for someone who's sympathetic — but if you're dorsally shutdown, a bath might just deepen the freeze. Lucas: Right. And this is why I think polyvagal theory is so useful for career burnout specifically. Because work is full of these subtle threat cues — the tone of a manager's email, the silence on a Zoom call, the feeling of being watched by your calendar. And your nervous system is responding to all of it, even if your conscious mind isn't. Luna: You know, this connects to something we've talked about before — the idea that burnout isn't just about hours worked, but about the quality of your recovery. And this gives us a more precise way to think about recovery quality. Lucas: It really does. And I want to be clear: I'm not saying you can breathe your way out of a toxic workplace or unfair expectations. Systemic problems need systemic solutions. But in the meantime — while you're figuring out your next move — these tools can help you survive without your nervous system paying the price. Luna: That's a good place to pause and ask: if this episode has been useful for you — if it's given you a new lens on your own burnout — we do have a small ask. This show is ad-free and listener-supported, and that's only possible because of people who find value in what we do. Lucas: Yeah. So if today felt worth a coffee to you — literally the price of one coffee — you can find us at buy me a coffee dot com slash fexingo. That's buy me a coffee dot com slash f-e-x-i-n-g-o. It's the easiest way to keep us going. Luna: And we mean it when we say it's the smallest possible ask. If you've gotten one insight you'll use, that's our goal. The coffee is just a bonus. Lucas: Alright. Back to the nervous system. So I want to talk about one more application of this at work — specifically, how meetings can be redesigned to actually promote recovery rather than drain you. And this is based on research from the University of California that found that meetings with a brief 'check-in' round — where each person shares how they're feeling — actually lower cortisol levels in participants. Luna: That makes sense because that check-in is a social engagement cue. It signals safety — 'I see you, you see me, we're in this together.' So a 60-second check-in at the start of a meeting can shift everyone's nervous system into a more collaborative state. Lucas: Exactly. And the opposite — jumping straight into agenda items, no warm-up — keeps everyone in sympathetic mode. So the meeting feels productive in the moment, but you walk out more drained than you walked in. Over a year, that cumulative drain is a huge driver of burnout. Luna: I want to try this with my team. Even just saying, 'How are you arriving today?' with no pressure to be deep. It's such a small shift. Lucas: And it's free. No app required. So to tie this all together: burnout is not a failure of willpower. It's a physiological state. And the path out is not about working less — though that can help — it's about retraining your nervous system to feel safe, even in an environment that's designed to keep you alert. Luna: And the first step is just noticing. The next time you feel your jaw clench, or your shoulders creep up toward your ears, that's your cue. Not to push through, but to reset. Lucas: Exactly. And if you do that one thing — just one physiological sigh, one soft gaze, one moment of signaling safety to yourself — you've already started the recovery. That's not woo-woo. That's neuroscience. Luna: I love that note. Thanks, Lucas. And thanks to everyone listening. We'll be back next time with another angle on sustainable careers.
