Why Anxiety Can Feel
Physical in the Body

A lot of people don't recognize their anxiety as anxiety — because it doesn't feel like worry. It feels like a tight chest. A stomach that won't settle. Muscles that are constantly braced for something. Headaches that show up for no obvious reason. You get checked out medically, everything comes back normal, and you're left wondering what's actually going on.

This is one of the things I find myself explaining often: anxiety isn't just a thought pattern. It's a full-body experience. And for a lot of people — especially those who don't think of themselves as "anxious" — the physical symptoms show up first.

Why Anxiety Lives In The Body

Your brain and your nervous system are constantly working together to keep you safe. When your brain perceives a threat — real or imagined, past or present — it sends signals through the body to prepare for action. Heart rate goes up. Breathing shallows. Muscles tighten. Digestion slows down. That whole cascade happens automatically, before you've had a chance to think about it.

The problem is that the brain doesn't always distinguish between a genuine threat and a thought, a memory, or an anticipated worry. So the same physical response that helps you react in a real emergency can get triggered by a stressful conversation, a looming deadline, or simply lying in bed trying to fall asleep.

Your brain isn't wrong for doing this. It's trying to protect you. But it isn't always right either — and part of what happens in anxiety counselling is learning to distinguish between a real signal and a false alarm.

Physical Symptoms That Are Often Anxiety

• Chest tightness or heart palpitations
• Shallow breathing or a feeling of not being able to get enough air
• Muscle tension — especially in the neck, shoulders, and jaw
• Headaches or migraines
• Stomach upset — nausea, cramping, or digestive issues that don't have a clear medical cause
• Fatigue that doesn't improve with rest
• Feeling dizzy or lightheaded
• Skin that flushes or tingles for no obvious reason

If several of these feel familiar — especially if you've had them checked out medically and nothing has turned up — anxiety may be worth exploring. That's not a diagnosis, just a starting point for curiosity.

The Anxiety Merry-Go-Round

One way I often explain anxiety is as a mental merry-go-round. The brain gets stuck circling the same question, the same fear, the same "what if" — again and again. And as it circles, it keeps filling in the gaps with assumptions rather than facts.

What if something is wrong with my health? What if this chest tightness is serious? Why do I keep feeling this way?

The merry-go-round speeds up. The physical symptoms intensify. And now the anxiety itself becomes something the brain is anxious about — which is a particularly exhausting loop to be caught in.

Learning to slow that loop down — to examine what's actually true versus what the brain is assuming — is one of the most useful things I work on with people dealing with ongoing anxiety.

After A Car Accident

Physical anxiety symptoms are especially common after a motor vehicle accident — and they're often mistaken for something else. The body went through something traumatic. Even after the visible injuries heal, the nervous system can stay in a state of high alert for weeks or months afterward.

You might notice it while driving down Bowen Road, merging onto the Nanaimo Parkway, or even just sitting in the passenger seat. The tightness in your chest. The sudden urge to grip the armrest. The feeling that something bad is about to happen, even though nothing is. That's your nervous system trying to keep you safe — and it's also a sign that it hasn't quite gotten the message that the accident is over.

This kind of response is well within the scope of ICBC counselling — and in BC, that counselling may be covered.

You're Not Imagining It

I want to say this clearly, because a lot of people need to hear it: physical anxiety symptoms are real. They're not "just in your head" — or rather, they are in your head, in the sense that they're neurological, but that doesn't make them any less real or any less worth taking seriously.

People sometimes come in having been told their symptoms are psychosomatic, or that they need to "just relax." That's not helpful advice for someone whose nervous system is genuinely activated. What's helpful is understanding what's happening, learning how to work with the body's response rather than against it, and gradually building a sense of safety again.

Change is possible. The nervous system is adaptable. And with the right support, these symptoms can ease — not because you're forcing them to, but because you're giving your brain and body the information they've been missing.

When Anxiety Affects Relationships Too

One thing worth noting: when anxiety is running high, it affects more than just the individual. It affects communication, connection, and closeness. If you've noticed that your anxiety is creating distance in your relationship — or if stress is affecting how you communicate — that's worth addressing alongside the anxiety itself.
