Why You Don’t Need Another Nervous System Hack Added To Your To-Do List – And What To Do Instead
If you spend any time on the internet or social media, you’ve probably noticed there is a lot of information — and misinformation — about the nervous system and how to “fix” it. Breathing hacks. Vagus nerve tricks. Cold plunges. Morning routines that somehow require an extra hour you don’t have.
Ironically, even trying to keep up with all of this can become another stressor on an already stressed-out nervous system. Then comes the next layer: trying to squeeze yet another “regulation tool” into an overscheduled day. Miss it? Cue the self-criticism.
Rather than overcomplicating things, I prefer to start with some simple questions: 1) What does a healthy nervous system actually mean? And 2) What does a healthy nervous system need? Once we understand the basic principles, it becomes much easier to work out what to do next (hint: it’s not calling yourself a failure because you were too tired to do your 10 minutes of meditation at the end of a long day).
What a Healthy Nervous System Actually Means
Let’s clear something up first. A healthy or “regulated” nervous system does not mean being in a calm state of zen at all times, regardless of what life throws at you.
What we’re actually aiming for is flexibility.
A well-functioning nervous system can move into states of stress or activation when needed — and then return to baseline once the stress has passed. You might think of it like a marshmallow: when you squeeze it, it compresses; when you let go, it slowly expands back toward its original shape.
Problems arise when it takes a long time to rebound, or when chronic stress keeps the system under constant pressure. Over time, the baseline itself becomes elevated — like a marshmallow that never fully puffs back up and remains partially squished.
So another key question becomes: why does modern life make it so hard for the system to return to baseline?
Why Flexibility is Hard in Modern Life
To keep things simple, our nervous system has two main pathways:
- The parasympathetic nervous system (often called “rest and digest”), which supports repair, social connection, and conserves energy
- The sympathetic nervous system (often called “fight or flight”), which mobilises energy to respond to danger
The role of our parasympathetic system is to keep us in a state optimal for everyday functioning and recovery. When there is an immediate threat — say, a lion chasing us — the sympathetic system kicks in, prioritising survival until the danger passes.
This system evolved over hundreds of millions of years and worked extremely well for its time. It is designed to respond to short-term threats. Once the danger is gone, the system settles and returns to baseline (i.e., the marshmallow puffs back up).
The problem is that modern stress rarely looks like a single, time-limited threat. Instead, it’s chronic and cumulative: work pressure, financial stress, constant notifications, social expectations, and ongoing uncertainty. Our nervous system hasn’t evolved fast enough to adapt to these conditions. Over time, this can keep the system switched on. This means prolonged activation of the HPA axis, disrupted cortisol levels, and neuroinflammation. This then impacts both physical and mental health (PMID: 40243556). It’s one reason so many people feel constantly overwhelmed, wired-but-tired, dysregulated, fatigued, and unable to properly rest.
What Does a Healthy Nervous System Need (i.e., to be Flexible)?
Because our nervous system hasn’t evolved to match the pace and demands of modern life, many of us need to be more intentional about the environments, relationships, and expectations we place ourselves in. This isn’t about eliminating stress or staying calm all the time — it’s about creating enough safety and support for the system to activate when needed and then return to baseline.
At its core, the nervous system is always scanning for one question: Am I safe, or am I under threat?
When stress is time-limited and there is time for recovery, the system does exactly what it’s meant to do. The marshmallow compresses — and then slowly puffs back up. Problems arise when stress is chronic, and the system never quite gets the chance to rebound.
With that in mind, from Polyvagal-Theory-informed frameworks, experiences that provide clear cues of safety, or our capability to adequately cope with a threat, tend to facilitate a return to baseline, such as:
- Consistency and predictability
- Safe, supportive relationships
- Clear and achievable expectations, a sense of control, and challenges that are shared with others (i.e., that we are not alone in this)
And other conditions make it harder for the system to recover, particularly when they are ongoing or feel inescapable, such as:
- Chronic or overwhelming demands
- Chronic overstimulation
- Unreliable or unsafe relationships
- High levels of uncertainty, low sense of agency, and feeling alone with the challenge
Seen this way, nervous system regulation isn’t about chasing calm or avoiding stress altogether. It’s about reducing the conditions that keep the system permanently compressed and increasing the ones that allow it to expand again.
Why “Trying Harder” Usually Backfires
Here’s the part that often gets missed: you can’t regulate a nervous system through pressure, perfectionism, or relentless self-improvement.
In fact, the performance pressure and self-criticism often found in perfectionism actively work against a healthy nervous system. Using the same system that contributed to dysfunction to try to fix it doesn’t tend to go well.
(Trust me — I’ve tried.)
From a nervous system perspective, this makes sense. Pressure keeps the sympathetic nervous system activated. It’s like continuing to squeeze the marshmallow and then wondering why it won’t puff back up. No amount of effort or “doing better” helps if the pressure itself never eases.
Instead, nervous system regulation tends to respond best to consistent, gentle, healthy changes, made slowly over time. Not perfection. Not optimisation. Just enough safety, predictability, and recovery for the system to stand down — so the marshmallow can expand back toward its original shape.
What to Focus on Instead
Rather than adding more hacks to your to-do list, focus on things that help your body feel safer and less under constant threat, such as:
- Establishing a basic routine, including a consistent sleep schedule and gentle movement
- Reducing internal pressure by cultivating self-compassion and easing harsh self-criticism
- Spending more time with people who fill your cup rather than drain it
- Reducing pressure where possible — by doing less (easier said than done, I know), asking for help, setting boundaries, learning to say “no”, and prioritising our own needs
- Practicing how to tolerate being bored and reducing constant sensory input
- Re-learning how to rest without guilt
- Evaluating roles at work or home to ensure expectations are clear and you have a reasonable sense of control (where possible)
- Doing things more slowly, instead of living in a permanent state of urgency (this one I have found particularly beneficial for me – but of course we are all different and some others might work best for you).
If this list looks overwhelming, it is not about doing it all at once or even doing it every day. Now might not even be the right time to work on this list at all. And that’s okay too. Again, we don’t want it to feel like more pressure. It’s simply about small, consistent changes over time that fit into your real-life. None of this is flashy. That’s kind of the point: you’re giving your nervous system more chances to feel “safe enough” instead of pushing it to keep bracing.
So… What About Breathwork and Nervous System Tools?
Tools like breathwork, yoga, and vagus nerve stimulation can be genuinely helpful — and I personally use many of them regularly. But they are exactly that: tools, not cures.
Trying to wedge a breathwork class into an exhausted, sleep-deprived, chronically overwhelmed week isn’t going to undo the broader context your nervous system is responding to.
Regulation isn’t about doing more. Rather, it’s about making life feel a little safer, slower, and more sustainable — consistently, over time.
And that’s something no hack can replace.
