Anxiety is more than just worrying — here's what it's actually doing to your body

Right, let's talk about anxiety. And not the "oh I feel a bit nervous" kind. I mean the full-body, what-the-hell-is-happening-to-me kind. The kind where your heart's going mental, your shoulders have relocated to somewhere near your ears, and your stomach is doing things that should be illegal. Fun times.

Here's the thing though... those symptoms? They're not random. They're not your body betraying you. They're your body doing what it genuinely thinks is helpful (bless it), gearing up to protect you from danger. The problem is, your body can't tell the difference between a lion chasing you and you replaying a conversation from 2019 at 3am. So it just… goes full survival mode. Every. Single. Time.

If you've ever sat there like "why does my anxiety feel so PHYSICAL?"... same. And understanding what's actually going on under the hood? That's where things start to shift. So let's get into it.

What's actually going on inside your body when anxiety hits

When anxiety rocks up (uninvited, as per), your body flips into fight or flight mode. You've heard this a million times, I know. But stick with me, because knowing WHY your body does what it does genuinely helps take the edge off.

Your heart rate shoots up, pumping blood to your muscles because your body thinks you're about to leg it or throw hands (you're not, you're in Tesco, but ok).

Your breathing goes shallow and fast, which is why you feel breathless or dizzy and then start panicking about THAT, which makes the whole thing worse (the gift that keeps on giving).

• Your muscles tense because apparently you need to be battle-ready at all times.

• You start sweating — your body tries to cool you down before you've even moved. Cheers for that.

• Your digestion basically clocks off — blood gets redirected elsewhere, hence the nausea, the butterflies, the general stomach chaos.

• Your senses go into overdrive — pupils dilate, you're hyper-alert, everything feels like Too Much.

None of this is a choice. It's automatic. And when you don't know why it's happening, it feels terrifying. But when you DO know? It's still uncomfortable, sure. But it's less "I'm dying" and more "ah, there you are again, you little gremlin."

How anxiety shows up in your body (because it's sneaky like that)

The annoying thing about anxiety is it doesn't look the same for everyone. You might get the full buffet of symptoms or just a couple of specialities.

Here's what tends to show up:

• Chest pain or tightness — like something's pressing down on you. (Cue: googling "am I having a heart attack" at 2am. We've all been there.)

• Dizziness or lightheadedness — the room goes a bit wobbly and you're convinced you're going to faint in public.

• Trembling or shaking — I literally thought I was cold the other week and it turned out to be anxiety. Plot twist of the century.

• Headaches or migraines — tension loves to set up camp right in your skull.

• Exhaustion — anxiety is KNACKERING. You've done nothing all day and yet you feel like you've run a marathon. In sand.

• Sleep problems — can't fall asleep, can't stay asleep, or you sleep for 12 hours and wake up still shattered. Cool cool cool.

• Stomach issues — nausea, bloating, the full digestive disco. Let's not elaborate further (you're welcome).

Sometimes these show up during or after something stressful. Other times they waltz in completely out of nowhere, which is the most unsettling part. But here's what I need you to hear: these symptoms are REAL. They're not in your head. Well — they start in your head, technically — but the physical stuff? That's your body waving a massive flag going "OI. Something needs attention."

So how do you actually deal with it?

I know, I know — this is the bit you actually came for. "Just tell me how to make it stop." And look, I wish I could give you a magic off switch. I really do. But anxiety doesn't work like that (rude, tbh).

What DOES work is learning to regulate what's happening in your body so you can actually hear what the anxiety is trying to tell you. Turn the volume down on the scream so you can catch the whisper underneath. Here's what helps:

• Breathing exercises — slow it right down. In for 4, hold for 4, out for 6. It literally tells your nervous system "we're safe, stand down." It feels too simple to work, but it does. Every time.

• Progressive muscle relaxation — start at your toes, tense for a few seconds, release. Work your way up. It sounds a bit woo-woo but honestly, it's your body learning to let go of what it's holding. And it's holding A LOT.

• Sit with it — this is the meditation bit, and before you roll your eyes, hear me out. Lie down (I never sit up for meditation, sue me), take five deep breaths, find where the anxiety lives in your body, and just… breathe into it. No judgement, no story, just attention. Think: baby cries, you pick it up and hold it. Nothing more, nothing less. The sensation softens. It always does.

• Move your body — a walk, some yoga, a stretch. Nothing heroic. Just enough to shift the energy that's stuck. Because that's what emotions are - energy. And it needs somewhere to go.

• Cut back on caffeine and sugar — both of these crank anxiety up without you even clocking it. I know. I'm sorry. The coffee stays (but maybe just the one).

• Build a routine that actually supports you — boring stuff: regular sleep, proper meals, actual downtime. Not glamorous. Very effective.

• Get support — talking to a therapist or coach isn't weakness. It's one of the smartest things I ever did. Genuinely. (My therapist changed my life in eight months. Eight. Months.)
  

Your body holds onto anxiety and it's trying to tell you something

Here's something that doesn't get talked about enough: your body doesn't just react to anxiety in the moment. It STORES it. If you've been anxious for a long time, that might show up as chronic muscle tension, persistent headaches, or even things like high blood pressure. Your nervous system has been on high alert for so long it's forgotten how to stand down.

So learning to listen to your body? Big deal. Massive deal. When you notice tension or discomfort, try pausing and asking yourself:

1. Where am I feeling this right now?

2. What thoughts or emotions are sitting alongside it?

3. Can I breathe into it, even for a second?

You're not trying to make it disappear. You're acknowledging it. And that simple act of paying attention — without trying to fix or fight or flee — is incredibly powerful. What you accept truly does dissolve. Maybe not instantly, maybe not completely, but enough to give you space to choose your next move from a grounded place.

This isn't about getting rid of anxiety (sorry)

I think this is where people get tripped up. We think healing means the anxiety vanishes. Poof. Gone. But that's not how emotions work (wouldn't THAT be nice though). The work isn't to erase what you feel — that's literally impossible. The work is to change your relationship with it.

When you understand what anxiety is doing to your body, you stop being at its mercy. You start to recognise it for what it is — a signal, not a sentence. A reminder, not a dictator. And from there, you get to respond differently. With awareness. With compassion. With agency.

Because here's the thing: you are an expansive being who can hold two truths at once.

You can feel anxious AND capable. Overwhelmed AND resilient. Scared AND brave. You don't need to be defined by a single emotion.

So start listening. Honour what your body's telling you. Treat yourself with the same kindness you'd give someone you love. Take small steps, consistently. That's where the real magic happens.

You are FABULOUS and the next move is always yours. Choose, with love.

If you want to explore more about how anxiety affects your body and mind, keep seeking knowledge and support. Healing is a journey, and every step counts.

P.S. If you've got a build-up of anxious energy sitting in your body, find a safe way to let it out. Journal. Move. Breathe. Scream into a pillow if you need to. Whatever works. Just don't let it sit there festering - it deserves to be felt, not stored.
