Stress Isn't the Problem, Getting Stuck There Is
by Michelle McKenzie
There's a common misconception about nervous system health: that the goal is to stay calm, always, and that any spike of stress or fight-or-flight activation is a sign something's wrong.
It isn't.
Your nervous system was never designed to be permanently regulated. It was designed to respond, to rise into alertness when something genuinely demands it, and then, crucially, to come back down again. That return to baseline, not the absence of stress itself, is what a healthy nervous system actually looks like. The problem most of us are living with isn't that we experience stress. It's that we get stuck there.
Stuck in the "On" Position
Fight-or-flight exists for good reason. It sharpens focus, floods you with energy, and prepares you to act. In short bursts, followed by real recovery, it's not just harmless, it's necessary.
What's changed is the recovery part. Modern life rarely gives the nervous system a clear "all clear" signal. Notifications, deadlines, financial pressure, a body that doesn't feel right, these don't resolve the way a genuine physical threat once did. So the system doesn't fully stand down. Over time, what should be temporary becomes a background hum that never quite switches off. This is dysregulation: not that you feel stress, everyone does, but that your system loses its ability to return home.
What Can Cause This
A nervous system can end up stuck for many reasons, often layered on top of each other:
Illness and infection, viral illness, long covid, or chronic infection can leave the system on high alert long after the original threat has passed.
Trauma, a single overwhelming event, or prolonged exposure to an unsafe or unpredictable environment, childhood or otherwise.
Chronic stress, ongoing pressure without adequate recovery, no single dramatic event required.
Grief and loss, real physiological strain, not just emotional.
Injury and physical pain, chronic pain keeps the body in a state of heightened vigilance.
Early life experience, how safe and regulated we felt in childhood shapes how our nervous system calibrates safety for the rest of our lives.
Understanding why your system might be stuck isn't necessary before you can begin supporting it, but it can make the process feel less confusing, and less like something you're failing at.
Your Nervous System Reads Signals, Not Intentions
One of the most useful things to understand is this: your nervous system doesn't know or care what you mean to do. It only responds to the signals you actually give it.
Telling yourself you're safe rarely works on its own, especially when your body is still picking up cues of threat: a racing heart, shallow breathing, tension in the shoulders. Thoughts do shape the nervous system, but more slowly, and less directly, than we'd like. What works better is sending your body different physical signals, a longer exhale, warmth, stillness, and letting your nervous system draw its own conclusions. Change the input, and the state tends to follow. This is why the practices further down are so simple: they're not about willpower, they're physical evidence that it's safe to stand down.
There's a related pattern worth naming. Every time the brain interprets a sensation as dangerous, racing heart, tight chest, it gathers a little more evidence that the body is unsafe, making it easier to slip into that state again next time. What helps is meeting these moments with a different signal entirely: "I hear you. You're uncomfortable, but you're not dangerous. This is a pattern, and patterns can change." I find it helps to remember the uncomfortable feeling isn't me, it isn't permanent, it's moving through me, not settling into me.
When a Virus Leaves the Alarm Switched On
For many people, this pattern arrives suddenly, after illness. Post-viral fatigue and long covid are two of the clearest examples of a nervous system knocked into a heightened state that never quite found its way back.
I've experienced this myself. During my own recovery from long covid, what struck me most wasn't just the exhaustion, it was how wired I often felt underneath it. Tired, but unable to properly rest. That's a textbook nervous system response: the body treating a virus as an ongoing threat long after the infection has cleared. This is part of why "just rest" often doesn't work for post-viral recovery, if the nervous system is still stuck in alarm, rest alone doesn't teach it how to come back down. That capacity often needs to be actively rebuilt.
When "Discipline" Is Actually Dysregulation
Some behaviours we praise as discipline are actually teaching the nervous system to stay on high alert. I've been guilty of this for years, forcing productivity when my body was exhausted. During my most recent bout of post-viral fatigue this year, I learned it the hard way: pushing through fatigue sends a direct signal that recovery isn't allowed. Do that enough times, and your body stops expecting rest at all.
A few patterns worth recognising, because I've lived every one of them:
Using busyness to avoid feeling, constant activity that never gives the nervous system a still moment to process anything.
Treating rest as something to be earned, if rest only happens once everything's done, and the list is never done, rest never really happens.
Pushing through stress without recovery time, the pattern underneath most of the others, no signal that the demand has passed keeps the system braced for more.
Suppressing emotions to appear composed, this doesn't make the overwhelm disappear, it just moves it inward.
Using self-criticism as motivation, a harsh internal voice is, physiologically, still a threat signal.
Avoiding help to prove independence, refusing genuinely needed support tells your body it has to manage everything alone.
None of these are moral failings, they're strategies that once served a purpose. Recognising this isn't about self-blame, it's often the first real step toward actually recovering.
What Your Body Might Need to Release
A trembling body is not malfunctioning. A shut-down body is not weak.
When someone is overwhelmed, shaking, crying, frozen, the instinct is almost always to say "calm down." But a trembling body is discharging. A body that goes still is doing exactly what an overwhelmed nervous system is built to do when fighting or fleeing isn't possible. Forcing stillness onto either state doesn't resolve it, it just interrupts a process already underway, often pushing whatever needed to move back down, unprocessed, to surface again later.
Nervous system regulation has, for many people, quietly become another full-time job, an endless effort to stay soothed, as if any dip out of calm is a problem to manage immediately. But sometimes your nervous system isn't asking to be calmed. It's asking to release something. Stress that gets suppressed rather than moved through doesn't disappear, it sits in the body as tension and bracing.
So it's worth asking honestly: what does my body want to release, and how can I let that happen? For some people that's movement, real, uninhibited movement, Qigong shaking, or dancing alone with no audience. For others it's crying, allowed rather than overridden because it doesn't feel "appropriate." Sometimes it's jumping, shouting, or shaking out your hands, anything that lets pent-up energy actually move through and out. None of this needs to look graceful. If the endless pursuit of calm hasn't worked, it might be because calm was never quite what was needed.
Breaking the Stress Habit
Many of us become genuinely habituated to our own stress response. Every anxious thought triggers a small hit of adrenaline and cortisol, and over time that pattern becomes so familiar the body starts to default to it. It isn't addiction in the clinical sense, but it behaves a lot like one, the nervous system simply reinforces whatever gets repeated most.
The encouraging part: this works in the other direction too. Deliberately practising other emotional states, gratitude, love, ease, doesn't just feel nice in the moment. Done often enough, it gives the nervous system a different pattern to default to instead, until calm becomes just as familiar as the old pattern once was.
Simple, Free Ways to Support This at Home
Nervous system regulation doesn't require expensive equipment. Small, consistent signals of safety, repeated often, are what genuinely help retrain the system.
Extend your exhale. In for four, out for six or eight. A longer exhale activates the vagus nerve and signals safety directly.
Try cardiac coherence breathing. In and out for around 5-6 seconds each, for five minutes. One of the most well-researched ways to shift toward a calmer state.
Hum, or sing. The vagus nerve runs directly past your vocal cords, vibration genuinely stimulates it.
Place one hand on your chest, one on your upper abdomen. The warmth and gentle pressure of your own touch can be genuinely calming, and it's discreet enough to do almost anywhere.
Splash cold water on your face, or hold something cold, triggering the mammalian dive reflex.
Move gently, not intensely. Walking or slow Qigong-inspired movement discharges stress hormones without adding more.
Lie with your legs up against a wall for ten to fifteen minutes. This gentle inversion is widely used as a restorative pose.
Get sunlight within the first hour of waking. This triggers a healthy cortisol awakening response that helps set a well-regulated pattern for the whole day.
Let your feet touch the ground, literally, barefoot outside for a few minutes when you can.
None of these need to be done perfectly. The nervous system responds to repetition more than intensity, a few minutes, several times a day, does more than one long session once a week.
Birdsong and Trees Are Doing More Than You Realise
Two of the simplest tools sit right outside your window.
Research, including work from the Max Planck Institute for Human Development, has found listening to birdsong is associated with reduced anxiety and more relaxed, parasympathetic nervous system activity, partly through "soft fascination," effortless attention that lets the more effortful parts of your focus genuinely rest. There's likely something older at play too: birdsong has meant safety throughout most of human history, and our nervous systems may still be listening for that signal.
Trees add another layer. They release compounds called phytoncides, and research led by Dr Qing Li at Nippon Medical School has found exposure is associated with reduced cortisol, lower blood pressure and heart rate, and a measurable increase in natural killer cell activity, an important part of immune function. Some studies have found this immune boost can persist for weeks. Phytoncide levels tend to peak twice daily, roughly a couple of hours after sunrise and again in early afternoon, though any time under trees counts for something.
You don't need a remote forest for either of these. An open window, a local park, a few minutes on a bench, all count.
It's Not About Never Being Stressed
If there's one thing worth taking from all of this, it's a gentler standard to aim for. You are not failing if you feel stressed or overwhelmed sometimes. That's simply being a person in a body that's doing its job.
What matters is whether you can come back down afterwards. That capacity is trainable. It responds to small, repeated, unglamorous practices far more than to willpower. And for those of us who've been through post-viral illness in particular, rebuilding it deliberately, rather than assuming it will simply happen with time, can make a real difference.
Your nervous system already knows how to do this. Sometimes it just needs the right conditions, and a little patience, to remember.
