Manage stress? Learn to self-regulate your nervous system.

Stress isn't solved on the mental level. It's solved in the body, through the nervous system that's actually running it.

Hello friends,

As a highly sensitive person, I'm used to feeling overstimulated fairly easily. My nervous system processes things more deeply than the average person does. That brings real gifts, and real challenges. For years I've researched and practiced how to avoid the trap so many HSPs fall into: going from one over-exhausted phase to the next, simply because we don't take good enough care of our nervous system along the way.

This matters just as much beyond HSPs. During the day, we all move between different levels of stimulation, whether we notice it or not. Your stress level is reflected in your nervous system, or to put it simply: in your body. Feeling highly stressed shows up as shallow breath, overwhelming thoughts or emotions, tunnel vision, a raised heart rate, tensed muscles, and often impulsive or reactive behaviour.

What chronic stress actually does

Stress means your body is flooded with cortisol and adrenaline. The adrenaline wears off, but cortisol stays and does its damage. Left unchecked, chronic stress has real effects on your health: from permanently tensed muscles, to inflammation in the body, to measurable shrinkage in the frontal cortex, the part of your brain responsible for decision-making.

Here's why. Chronic stress means your "fight or flight" mode, the sympathetic part of your nervous system, stays dominant. You're not spending enough time in "rest and digest" mode, its counterpart, the parasympathetic nervous system. Our bodies always seek balance. But the sheer amount of daily stimulation and information most of us live with keeps us trapped in what's sometimes called sympathetic overdrive, meaning too much stress, and too little relaxation.

Managing stress means managing the nervous system

Have you ever tried lowering your own tension by telling yourself to relax? Just like telling someone else to calm down mid-argument, it rarely works. Stress can't be solved on the mental level. It has to be worked through the body.

Here are three ways to calm your nervous system and lower your stress response.

One: work with the breath. The breath is managed by the same part of the nervous system that raises or lowers your stress response. It always mirrors your mental state. When you sleep, your breath is slow and deep. When you're anxious, it's shallow. If you want to relax, you need to breathe as if you already are. A well-researched technique is the physiological sigh: a double inhale through the nose, followed by a long exhale. Even a few slow, deliberate breaths can nudge your body into rest-and-digest mode.

Two: take true breaks. A study from Microsoft's Human Factors Lab found that during the day, depending on our stimulation level, we move through different brain wave states. Beta waves roughly represent stress, alpha waves represent relaxation. Most of us stay in beta for most of the day, but we need to return to alpha to avoid burning out. When you scroll your phone or check email on a break, you stay in beta. Your brain never actually resets. A true break is one that really calms you down: closing your eyes, a short meditation, stretching, or a five to ten minute walk.

Three: activate the sympathetic nervous system, in small, intentional doses. While we generally want to reduce fight-or-flight activation, some techniques deliberately put the body into a state of heightened stress on purpose, to build resilience over time. These are sometimes called hormetic practices: things that would harm you at a high dose, like breath holds, cold water, or fasting, actually strengthen the immune system in small ones. Intense workouts and sauna visits fall into a similar category. Meditation, even though it isn't remotely life-threatening, seems to have a comparable effect: it also builds resilience over time.

To sum it up, if you want to self-regulate your nervous system:

  • take a few deep, conscious breaths, or the physiological sigh, whenever you notice tension building
  • take five to ten minutes of true breaks between meetings during the day
  • build a weekly hormetic routine: a cold shower, a longer meditation, or a sauna visit

Which of these are you already using? And which one would you want to build into your week? I'd love to know.

Have a lovely day,

Questions people ask about this

Where do I start if I want to try this with my team?
Start with the physiological sigh: double inhale through the nose, long exhale out. It takes ten seconds and works even in the middle of a meeting. Try it yourself for a week before you bring it to anyone else. You can't teach a regulation practice you haven't felt.
How can I work with Sophie on this?
Nervous system regulation is one of the core tools in Module 6 of my 8-week Emotional Intelligence in Action programme, alongside real ways of working with emotions instead of just managing them away. Book a Discovery Call and I'll walk you through the full programme.
Isn't stress just something I have to push through?
No. Chronic stress means your body stays flooded with cortisol, and over time that shows up as tensed muscles, inflammation, and measurable shrinkage in the part of the brain responsible for decision-making. Pushing through doesn't lower the stress level, it just moves your baseline. The nervous system needs real breaks to reset, not more willpower.
