How to Reset Your Nervous System When You're Stuck in Fight-or-Flight

Resetting your nervous system in a Childs Pose

Ever caught yourself sitting at your desk and suddenly realised your shoulders are all the way up to your ears? Or that your jaw has been clenched tight for the last three hours?

We usually just call this 'being stressed'. But biologically, your body calls it survival mode.

If you’ve been feeling wiped out, easily overwhelmed, or physically tight no matter how much you stretch, your nervous system might be stuck in a loop.

Here is the science of why that happens, and why rolling our your yoga mat helps your body to reset.

The Science: Pinging Inboxes vs. Saber tooth Tigers

If you've been to one of my classes, you most likely will have heard me talk about your autonomic nervous system and the fact it has two modes:

1. The Sympathetic State (Fight-or-Flight): This pumps out adrenaline, speeds up your heart, and tightens your muscles so you can run away from danger.

2. The Parasympathetic State (Rest-and-Digest): This lowers your heart rate, heals your body and lets your muscles relax.

   
   

Back in the day of our ancestors, fight-or-flight was triggered by a physical threat, like a saber tooth tiger. You ran, you survived, and your body went back to resting.

Today, the reality is that your brain can't tell the difference between a charging predator and a modern trigger, like being stuck in traffic, running late for a meeting or a passive-aggressive email.

Because these micro-stresses never truly disappear, your body can unfortunately stay stuck in fight-or-flight.

Why You Can’t 'Stretch' Away Stress

Have you ever noticed that when you're really stressed, a deep, intense workout or aggressive stretching can make you feel worse?

That’s because your brain treats muscle tightness as a protective shield. If your nervous system feels unsafe, it will literally lock your muscles down.

You can't force a stressed-out muscle to relax. You have to change the signal coming from the brain first.

Enter Yoga

This is why a mindful yoga practice matters so much.

When you try to think yourself out of stress, it rarely works (has anyone ever calmed down by being told to "just calm down"? No!). But yoga works by using the body to talk to the mind.

By slowing down our movement, softening our gaze, and taking deep, belly breaths, we work to stimulate the vagus nerve (the nerve that acts as the body's natural brake pedal). This sends a powerful physical message straight to your brain: "You are safe. You can drop the shield".

Recently during my own practice, I’ve been exploring Somatic movement - which just means small, gentle, conscious micro-movements to release chronic tension without forcing anything.

You may have noticed that I’ve been weaving some of these into our weekly classes.

Come as you are

Yoga isn't about creating perfect shapes or being flexible. It’s about giving your nervous system a safe space to release tension, breathe and remember how it feels to relax.

Whether you are feeling happy, sad, exhausted, or feeling the pressure of everyday life... your mat is waiting for you.
