Is Stress a Killer… or a Motivator?
I recently listened to a talk that unsettled something I had quietly accepted as fact: stress is bad for you.
But the research says something more complicated.
Psychologists like Kelly McGonigal and Alia Crum have shown that two people can experience the same stressor and have very different physiological outcomes.
In one large longitudinal study of over 29,000 adults followed for eight years, high stress alone did not predict higher mortality. What did predict it was the belief that stress was harmful. Those who experienced high stress but did not see it as damaging to their health did not show the same increased risk.
Same stress. Different story. Different biology.
That finding stopped me.
Because if I’m honest, stress has often been fuel for me.
Deadlines sharpen me. Risk energises me. Pressure has built parts of my career. I do not collapse under it. I often seek it.
But here is what I’ve realised.
At some point, it became too much. Or maybe it lasted too long. And somewhere along the way, my relationship to stress shifted.
It stopped feeling like a motivator.
It started feeling like a threat.
And that shift changes everything.
When Stress Becomes a Loop
The stressor itself may be short-lived. A difficult conversation. A piece of bad news. A setback.
But the mind has a remarkable ability to extend the experience long after the event has passed. Replaying scenarios. Anticipating worst-case outcomes. Analysing tone. Assigning meaning.
Researchers call this rumination. And it turns acute stress into something more chronic.
What fascinates me is that stress, biologically, is designed to be cyclical. A spike. A response. A recovery.
But when we replay the spike, the body continues to respond as if the threat is ongoing.
It’s not dramatic. It’s subtle. A heightened state that lingers longer than it needs to.
And I’ve noticed something else.
When something stressful happens, I tend to process it inwardly. I think about it. I analyse it. I feel it. It can colour my entire day.
My husband, on the other hand, addresses it and moves on.
The event is the same. The duration is not.
Which raises a question I can’t ignore.
Are There Gender Differences in Stress?
Science does suggest some differences in how men and women respond to stress.
Traditional research framed stress through a “fight or flight” model. More recent work proposes that women may more often display a “tend and befriend” response, a concept introduced by psychologist Shelley Taylor. The idea is that women, historically responsible for caregiving, may have evolved to respond to stress by seeking connection and social bonding rather than confrontation.
There are also hormonal influences. Oxytocin, often associated with bonding, interacts differently with stress hormones in women. Some studies suggest women may be more prone to rumination, while men may externalise stress differently.
But this is where it becomes complex.
Women are often encouraged to be emotionally aware. That emotional intelligence is powerful. But does heightened emotional processing sometimes mean we stay in the experience longer?
Or are we simply more open about the fact that we are stressed?
The research does not suggest that one sex handles stress better. It suggests we may handle it differently.
And difference does not automatically mean disadvantage.
Stress as Fuel
Here is the part that feels hopeful.
If my relationship to stress changed once, it can change again.
That means it is not fixed. It is not destiny. It is dynamic.
Experts studying stress mindset suggest that how we interpret our physiological response matters. Viewing a racing heart as readiness rather than panic changes cardiovascular patterns in measurable ways. Brief interventions that reframe stress as enhancing rather than debilitating have been shown to alter hormonal ratios associated with resilience.
This does not mean pretending stress is pleasant.
It means recognising that stress is energy.
Energy can build momentum. Or it can erode stability.
The key difference, according to the science, lies in interpretation, recovery, and whether we allow the stress response to complete its cycle.
Changing the Relationship
If I had mastered this, I would not be writing about it.
But what research increasingly suggests is this:
Studies on stress recovery emphasise the importance of completing the physiological cycle. Movement. Social connection. Cognitive reframing. Even how we label our experience can influence the body’s response.
The goal is not to become indifferent to stress.
The goal might be to move from threat to challenge more quickly.
So Is Stress a Killer?
The evidence suggests stress itself is not inherently lethal.
Chronic, unprocessed stress is where risk accumulates.
Which brings me back to the question I started with.
Stress has been a locomotive in my life.
But when it shifts from motivator to perceived danger, it drains rather than drives.
The good news is this: if a relationship with stress can change once, it can change again.
And perhaps that is the real power.
Not eliminating pressure.
But learning, gradually, to relate to it differently.
