Stress Isn't Killing You. Your Opinion of It Might Be.

By John Corbett | Psychologist | Hong Kong

There is a study I come back to more than almost any other in my work.

Not because it's the most dramatic finding in psychology. But because it contains something that, once you really understand it, changes the way you relate to one of the central experiences of professional life.

Here is what the researchers found.

In 1998, a team at the University of Wisconsin surveyed nearly 30,000 American adults. They asked two questions: how much stress had you experienced in the past year, and did you believe that stress was harmful to your health?

Then they tracked those people for eight years.

Those who reported high levels of stress and believed that stress was bad for their health had a 43% increased risk of premature death over the follow-up period.  

Forty-three percent. That is a large number. It is the kind of number that gets into conference presentations and wellness campaigns and corporate health programmes. And it does, because it sounds like confirmation of what most people already believe: stress is dangerous, and we need less of it.

But here is the part that almost never makes it into the conference presentation.

Those who reported equally high levels of stress yet did not perceive stress as harmful to their health showed no elevated mortality risk at all. In fact, their death rates were among the lowest in the entire study — including lower than people who reported having very little stress.  

Read that again.

High stress. No harmful belief about it. Among the lowest mortality rates in the study.

The stress was not the variable. The belief about the stress was the variable.

What this actually means

I want to be careful here, because this finding is easy to misread in two directions.

The first misreading is: stress is fine, carry on. That is not what the research says. Chronic, unmanaged, unrelenting pressure — without adequate recovery, without meaning, without support — has real costs that are well-documented across decades of research. The point is not that stress is harmless.

The second misreading is that this is a simple motivational message: just think positively about stress and you'll be fine. That is also not what the research says, and I'll come to the nuances shortly.

What the research does say — clearly, with a sample size of 30,000 people tracked across eight years — is that the story you tell about stress is not separate from the experience of stress. It is part of the mechanism. The belief and the biology are not running on parallel tracks. They are interacting, in ways that produce measurable differences in health outcomes.

This is important. Not as a thought experiment. As a practical fact about how professional life in Hong Kong — one of the highest-pressure environments on the planet — is actually lived.

The wellness industry has been giving you the wrong message

For roughly forty years, the dominant narrative about stress has been consistent: stress is harmful, stress is the enemy, the goal is to have less of it.

This message is everywhere. It is in corporate wellbeing programmes. It is in the breathwork apps and the mindfulness courses and the executive retreat offerings. It is implicit in the way stress is discussed in medicine, in leadership writing, in the popular press.

Stanford psychologist Alia Crum finds that roughly 85% of people surveyed in her studies view stress as more debilitating than enhancing. This is not surprising — for years, leading voices in health have been warning about the many harmful outcomes associated with stress.  

But that message, delivered at scale and without nuance, has a problem. By framing stress as uniformly dangerous — something to be minimised, managed, escaped — it ensures that the people who cannot escape it, who live and work in high-pressure environments where stress is structural rather than occasional, are guaranteed to experience it as threatening. Not because the pressure is different. Because the interpretation is loaded in one direction.

Crum's research found that stress mindset — whether someone holds a stress-is-enhancing or stress-is-debilitating belief — affects not just how people feel about stress, but how their bodies respond to it and how they perform under it. 

In a study with employees at a financial institution, those who watched videos presenting stress as useful — improving immunity, creativity, and work quality under pressure — subsequently showed more adaptive physiological stress responses and were more open to feedback than those who had watched videos presenting stress as harmful.  

A short intervention. Measurable biological and behavioural difference. The mind and body are not as separate as the wellness industry's product categories suggest.

What stress actually signals

Here is a reframe that I find genuinely useful in the work I do with executives and founders in Hong Kong.

Stress is not a sign that something is wrong. It is a signal that something matters.

You do not feel stress about things that are irrelevant to you. The racing heart before a high-stakes presentation, the heightened alertness before a difficult negotiation, the sharpened focus before a decision with real consequences — these are your nervous system responding to the fact that this matters. That there is something at stake that is worth caring about.

McGonigal describes it this way: stress is what arises when something you care about is at stake. The adrenaline, the physical mobilisation, the cognitive sharpening — all of it emerges to help you meet a moment that matters.  

In that frame, the presence of stress is not evidence of a problem. It is evidence of a life being lived at a level where things have real stakes. Of work that genuinely matters. Of relationships and outcomes you are not indifferent to.

This is not a denial of the cost. It is a more accurate account of what the cost is for.

The biology of how you interpret it

There is a specific physiological mechanism behind all of this that is worth understanding, because it turns an abstract idea into something concrete.

When you encounter a stressful situation, your body responds in one of two ways, depending significantly on how you appraise what is happening.

If you interpret the situation as a challenge — demanding, but within your capacity to meet — your sympathetic nervous system activates. Heart rate increases, blood flow to muscles and brain improves, hormones associated with energy mobilisation are released. The physical experience is intensity. The functional effect is preparation for action.

If you interpret the same situation as a threat — something that exceeds your resources — a different hormonal system activates alongside the first. Cortisol rises more sharply. Blood vessels in the periphery constrict. The body prepares not for engagement but for damage limitation.

Research by Crum and colleagues at Stanford demonstrated experimentally that inducing a stress-is-enhancing mindset improved responses to both challenging and threatening stress — producing more adaptive cognitive, emotional and physiological outcomes than the stress-is-debilitating condition.  

The physical inputs are identical. The interpretation changes the output.

Research with Navy SEAL candidates found that those who held stress-is-enhancing beliefs — who believed that stress improves health, performance and wellbeing — outperformed those with stress-is-debilitating mindsets in one of the most physically and mentally demanding training environments that exists.  

These are not people who needed a mindset intervention. They are among the highest-performing humans in controlled conditions. And their beliefs about stress still predicted their outcomes.

The nuances that matter

I said I would come back to the nuances, and they are worth being honest about.

The Wisconsin study, and the broader stress reappraisal research, is genuinely important. It is also not a complete picture, and presenting it as one would be misleading.

More recent research has raised the question of whether the association between perceived stress and mortality is partly explained by the fact that people with underlying health conditions may be more likely both to perceive stress as harmful and to die earlier — meaning the causal direction is not entirely clear.   The relationship between stress beliefs and outcomes is real. It is also complex, and science does not stand still.

What the research does not support — and what I want to be explicit about — is the idea that a positive mindset about stress cancels out the effects of genuinely unsustainable working conditions. Chronic sleep deprivation, the absence of recovery time, years of unrelenting pressure without adequate support — these have costs that are not resolved by interpretation alone. The body keeps its own account. Thinking well about a broken system does not fix the system.

And there is a version of this message that can be weaponised — by organisations, by professional cultures, by the stories we tell ourselves — to justify conditions that are genuinely damaging. The argument that stress builds character, that pressure is the proof of ambition, that the discomfort is the point — this can be a route to genuine growth. It can also be a rationalisation for something that should simply stop.

The distinction is not always obvious from inside it. Which is part of why having somewhere to think it through honestly — with someone outside the system — tends to be useful.

What this changes in practice

If the story you tell about stress shapes the experience of stress and its effects on your health and performance — which the evidence suggests it does — then the relevant question is not simply how do I have less stress?

It is: what story am I currently telling about the stress I'm carrying?

For most professionals in Hong Kong, that story sounds something like: this is damaging me. This is unsustainable. This is the price I'm paying. I need to get through this period and then it will be different.

That story is not wrong, exactly. But it is loading every stressful moment with the additional weight of threat — the interpretation that the body is being harmed, that capacity is being depleted, that the pressure is evidence of something wrong rather than something meaningful.

And the research suggests that story is not neutral. It changes the biology. It changes the performance. And at scale, across eight years, it changes the outcomes.

A different story is also available. Not a false one. Not a performance of resilience. But something more like: this is hard, and it is hard because it matters, and my body is responding because I am trying to meet something that has real stakes.

That story does not make the pressure disappear. It does not replace adequate sleep, sufficient recovery, honest relationships, or addressing what genuinely needs to change. But it changes what the pressure means. And meaning, as the research consistently shows, is not separate from mechanism.

It is the mechanism.

The question underneath all of this

There is something deeper in the Wisconsin finding that I want to name, because I think it points toward something important.

The people in the study who experienced high stress without being harmed by it were not people who had less pressure. They were people who related to that pressure differently. Who had, in some way — consciously or not — found a frame in which the stress made sense as part of a life they were choosing.

Stress without meaning tends to break people. Stress in the service of something that matters tends, in the research and in my experience of working with people, to build them.  

The question this asks of anyone in a high-pressure professional environment is not primarily about technique. It is not about which breathing exercise or which morning routine. It is the more fundamental question of whether the stress you are carrying is in the service of something you actually care about — or whether it is the cost of a life that, when you are honest with yourself, has drifted from what you meant to build.

That is a harder question. It takes longer to answer. And for many people, it is the one that is actually worth sitting with.
