Why High Performers Lead from Stress Without Realising It

[00:00:01]:
High performers don’t live in denial about stress. They know it’s there and they’ve learned how to handle it, how to keep delivering results and how to make it part of their leadership identity. But what most people don’t realise is that workplace stress isn’t just something you manage, it’s something that quietly shapes how you lead from the inside out before you ever make a decision or walk into a room. Now, According to the U.S. occupational Safety and Health Administration, around 83% of American workers report experiencing work related stress, with many of them saying that their job is a significant source of that pressure. And even in New Zealand national workplace wellbeing data and in New Zealand national workplace wellbeing data shows that around one in five workers report feeling stressed at work, often or always. So this isn’t stress going unnoticed, this is stress being normalised. And here’s how that normalisation actually shows up.

[00:01:06]:
Not in big, dramatic moments, but in very small, very professional ones. It’s the way your body subtly braces before a meeting, even when you’re prepared. The shallow breath you don’t notice until you finally exhale once it’s over. The way your jaw tightens when someone asks a question you weren’t expecting, not because you don’t know the answer, but because your system reads uncertainty as something to manage. It’s scanning the room as you speak, tracking reactions, calibrating yourself in real time. It’s the quiet relief when you’re the one in control of the agenda. And that low level irritation when things feel inefficient or sloppy. And that’s according to your definition, right? So none of this feels like stress in the traditional sense.

[00:01:57]:
It feels like focus, it feels like responsibility, it feels like being good at what you do. And in terms of behaviour, well, this is where the nuance really matters. Clear talking points are often just good leadership, but knowing the outcomes you’re driving towards. Framing your message with intention, preparing so others can move forward with clarity. Well, that’s not the issue. The shift happens when preparation quietly turns into scripting. When you write out exactly what you’re going to say word for word, even though you know the material inside out. When spontaneity starts to feel risky, not strategic.

[00:02:40]:
When precision becomes less about impact and more about preventing something from going wrong. And then it follows you home. It shows up when you finally lie down at night and notice that your jaw is aching, not from the day itself, but from how long you’ve been holding it. The clenched teeth as you’re trying to fall Asleep, the mind that stays alert even when the body is horizontal. You’re not thinking about work in any obvious way. But the load hasn’t been set down, it’s been normalised. And this is what it looks like when leadership’s carried in the nervous system rather than just in the calendar. And because it works, because you’re competent and respected and capable, it never gets questioned.

[00:03:26]:
It just becomes the internal posture you lead from. And if, as you’re listening to me, you’re thinking, this sounds a bit like me, here’s what I want you to know. None of this means that there’s something wrong with you. It doesn’t mean you’re anxious or overthinking or doing leadership badly. What it means is that your nervous system learned a very effective way to keep you safe, respected and successful. And once you see that, then this whole conversation’s gonna shift. Now, this is where the biology gets interesting, right? Because cortisol, well, it’s usually talked about as a stress hormone, but researchers are starting to describe it more accurately as an anticipation hormone and how its primary role is mobilisation in response to anticipated demand. It helps allocate energy, sharpen attention and prepare your body for what it predicts will be required of you.

[00:04:29]:
It’s quite a different thought process around cortisol, right? So cortisol is not inherently bad. It rises when you anticipate a challenge, a decision, responsibility, performance evaluation, potential consequences. In regulated systems, anticipation changes with context. Cortisol rises when something genuinely needs your attention, and then it settles again when that demand passes. So the issue isn’t cortisol itself. The issue is what your nervous system expects and how often it expects it. When anticipation becomes biassed towards vigilance, towards staying on top of things, managing variables, being ready just in case cortisol doesn’t spike and resolve, it stays circulating, just enough to keep your body organised around readiness rather than recovery. And so, over time, that pattern is associated with increased inflammatory signalling in your body.

[00:05:32]:
Not acutely, not dramatically, but subtly and cumulatively. And that has an impact on your health. And alongside that, there’s another signal that your system is constantly sending. And you can feel this in your breath. It stays higher in your chest, shorter, more responsive. That breathing pattern sends information back to your brain that something still needs monitoring, that awareness is required. It’s essentially a call to remain vigilant. Now, physiologically, this looks very similar to anxiety.

[00:06:11]:
So even if you don’t consciously feel anxious, you feel incapable, alert, switched on, your system never fully stands down and it Acts as if you’re anxious. And when your system doesn’t stand down, rest doesn’t quite do what it’s meant to do. Your sleep is lighter, your recovery takes longer, your body is technically off duty, but it’s still on call. Leadership still happens, you still perform, but it costs more internally than it needs to. This is also where the stress response becomes self reinforcing, when readiness and vigilance are the default. The system that governs your stress hormones, known as the hypothalamic pituitary adrenal axis, or the HPA axis for short, because it’s a bit of a mouthful, Right, well, this stays more active than it needs to be. So the HPA axis is essentially the communication loop between your brain and your adrenal system. And it’s constantly integrating signals from your nervous system about what’s expected of you, what matters, and whether there’s demand coming that you need to be, be ready for.

[00:07:20]:
So if your system has learned that leadership equals responsibility, consequence and being on top of things, that’s the message your HPA access keeps receiving. Stay alert, stay prepared, stay responsive, and it sends a cascade of hormones in response to that message. And this doesn’t happen consciously. Your body’s not choosing vigilance. That’s defaulting to efficiency. Because the more familiar a pattern is, the faster and more automatically it runs. It requires less energy to repeat a well rehearsed response than to create a new one. And that’s why familiar patterns feel safe.

[00:08:01]:
And efficiency equals safety biologically because it conserves energy and it reduces uncertainty. So your system keeps selecting the same internal posture, not because it’s ideal, but because it’s predictable. This worked. I stayed capable. I didn’t die. I stayed respected. Let’s keep doing that. Now.

[00:08:24]:
The challenge is that leadership often evolves faster than biology updates. And unless your body is shown something different, not told but experienced, it keeps leading from the last version of safety that it remembers. And that could be a version that’s built around vigilance, preparedness, holding it together. And this is why simply telling yourself to slow down, well, it doesn’t land. It’s why ease can feel unfamiliar, why presence can feel slightly exposed. Your body isn’t resisting rest, it’s checking for risk. It’s asking whether letting go of vigilance might mean missing something important, losing momentum or dropping the ball. And this is the quiet ceiling that many high performers eventually meet.

[00:09:15]:
Not because your body can’t handle leadership, but because it’s been carrying leadership through a survival based strategy. And it was never designed for longevity, depth or sustained influence. And here is what my clients tend to be most surprised by. You see, leadership doesn’t lose its edge when your body no longer has to stay vigilant to feel safe. It actually sharpens when safety is created internally rather than managed through effort. Your system frees up capacity. Attention becomes cleaner, decisions land faster. You’re no longer scanning for what might go wrong, so you can actually sense what’s needed.

[00:10:02]:
And this is when leadership starts to feel different in your body. You’re still prepared, but you’re not braced. You’re still decisive, but you’re not holding yourself tight. Presence replaces monitoring. Authority comes from steadiness rather than tension. And the people around you, well, they feel it. Not because you’re doing something differently on the surface, but because your nervous system is not no longer asking the room to confirm your safety. That’s important, right? Your nervous system is no longer asking the room to confirm your safety.

[00:10:41]:
When your body doesn’t need vigilance to lead, it can respond instead of anticipate. And that’s a very different biological state. Breath naturally drops lower, muscles soften without collapsing. Cortisol rhythms begin to change because anticipation is no longer biassed towards constant readiness. You still get access to that surge of clarity and energy when something matters, but you don’t need to live in stress to reach it. The surge becomes available on demand, rather than running in the background all day. And it means you feel it more as well, because you’re not habitualised to it. Now, this is also where rest starts to work.

[00:11:25]:
Not because you’re forcing yourself to relax, but because your system finally trusts that it doesn’t need to stay on call. Sleep deepens, recovery feels genuinely restorative, not just enough to get you through the next day. And leadership stops costing you so much internally as a result. So nothing about this requires you to be less ambitious, less capable or less committed. It’s not about doing less. It’s about no longer needing stress to access your clarity or authority or your impact. So if there’s one takeaway from today, let it be this. You don’t need to change how you lead.

[00:12:13]:
You don’t need to try to relax more or to fix yourself. What’s been missing isn’t effort or strategy. It’s language for what’s been shaping your experience of leadership all along. And I’ve noticed that once that layer is named, something in the body tends to settle because it finally makes sense. And if this conversation’s been lighting up little moments of resources, recognition for you, then you’re gonna love what we’ll be talking about in Biology of Leadership. It’s a free three day live experience where we explore what leadership does to your body and how your body quietly shapes your leadership. In return, we’ll look at leadership as a physiological environment, the hidden cost of sustained responsibility, and what actually supports capacity and presence over time. And there’s nothing you need to do to prepare for it.

[00:13:18]:
Nothing you need to become. You just get to show up, be there, listen, and notice what clicks for you. So if you’re curious, if there’s a little nudge while you’re listening to my description of biology of leadership, you can save your seat at TracyTutty Co NZ forward/leadership Biology. And I would genuinely love to have you there with me. Sending you lots of love. Bye for now.
