You have a big meeting tomorrow and you can't eat. You're waiting for difficult news and your stomach won't stop turning. Before a confrontation, the nausea arrives before you've said a single word.
This isn't in your head. It's in your body. And it's doing exactly what it's designed to do.
Your gut has a nervous system of its own
The gut is sometimes called the "second brain" — and for good reason. It contains around 500 million nerve cells and produces more than 90% of your body's serotonin, one of the chemicals most associated with mood and wellbeing.
These two nervous systems — the one in your brain and the one in your gut — are in constant conversation, connected by a long nerve called the vagus nerve. When your brain perceives a threat (a difficult conversation, an uncertain outcome, a loaded situation), it sends signals down this highway instantly.
Your gut gets the message before your conscious mind has fully processed it.
If you've heard this, you're not imagining things and nothing is wrong with your body. Your body is doing its job — translating emotional signals into physical ones.
What your body is actually trying to tell you
Anxiety in the body is a survival mechanism that dates back thousands of years. When your ancestors encountered danger, their bodies flooded with stress hormones — cortisol and adrenaline — to prepare for fight or flight. Digestion slows down (the body doesn't need it right now), blood moves to the muscles, heart rate increases, breathing shallows.
The problem is that your body uses the same mechanism for a presentation to your boss that it would for a lion. It can't tell the difference. So it does what it always does: it mobilises everything it has.
Working with your body, not against it
When the physical symptoms of anxiety arrive, the instinct is often to try and override them — to think your way out of feeling panicked, to tell yourself to calm down, to push through.
But the body doesn't respond well to commands. Trying to reason with a racing heart rarely works, because the signal is coming from a part of your nervous system that doesn't speak in words.
What works better is working with the body:
- Slow, extended exhales — a long out-breath activates the parasympathetic nervous system (the "rest and digest" mode) and slows the heart rate. Even a few breaths can shift things.
- Naming what you feel in the body — "my chest is tight, my stomach is knotted" — has been shown in research to reduce the intensity of the sensation, because it brings the prefrontal cortex back online.
- Gentle movement — a walk, even a short one, helps metabolise the stress hormones your body has just produced.
- Warmth — a warm drink, a hand on your own chest, a hot shower — signals to your nervous system that you're physically safe.
When the body keeps sending the same signal
If you're experiencing physical anxiety symptoms regularly — nausea before most social situations, tension headaches on most workdays, stomach problems that track your stress levels — that's your body telling you something that needs more than a breathing exercise.
Therapy that works with both mind and body can help you understand what's triggering the anxiety, interrupt the patterns that keep it running, and give your nervous system genuine reasons to feel safer — not just managed.
Your stomach has been trying to tell you something. It might be worth finally listening.
