Why does your heart race and your chest tighten before a work meeting that poses no real physical threat? The truth is that your nervous system was built for a different world, one where danger meant something you could see, hear or run from, and it has not caught up to the fact that today’s stress is mostly invisible, ongoing and impossible to outrun.
If you have ever felt your body respond to an email, a bill or an awkward conversation as though your life was in danger, you are not overreacting. You are experiencing a nervous system doing exactly what it evolved to do, just aimed at the wrong kind of threat.
Deep in the brain sits a small structure called the amygdala, often described as the body’s smoke alarm. Its job is simple: scan the environment for danger and sound the alarm the moment something looks, sounds or feels threatening. For most of human history, that meant genuine physical danger, a predator in the grass or a rival tribe on the horizon.
The problem is that the amygdala cannot tell the difference between a tiger and a text message from your boss. To your brain, an unpaid invoice, a difficult family conversation or a packed inbox can trigger the same alarm as a genuine physical threat. Your body responds accordingly, flooding your system with cortisol and adrenaline, tightening your muscles and quickening your breath, all in preparation to fight or flee something that was never actually there.
We now live in a world of constant, low grade stimulation. Notifications, news updates, financial pressure and social comparison all arrive faster than our nervous systems can process. Where our ancestors faced short, sharp bursts of danger followed by long periods of safety, many of us are living in a near constant state of low level alert, checking phones, scanning inboxes and bracing for the next demand on our attention.
This is sometimes called a dysregulated nervous system, and it can show up in ways that do not always look like classic anxiety. You might notice:
These are not signs of weakness or a lack of resilience. They are signs of a nervous system working overtime.
The encouraging news is that the nervous system is not fixed. It can be taught, gently and gradually, that it is safe to stand down. This is where working with a psychologist can make a genuine difference, not by telling you to simply think positive or push through, but by helping you build a felt sense of safety in your body again.
At Marie Carmody Psychology, an integrative mind and body approach is used to help clients understand and regulate their nervous system responses, rather than just talking about symptoms in the abstract. This might involve learning to notice early warning signs of a stress response, practising grounding techniques that signal safety to the brain, or gently exploring the deeper patterns and past experiences that keep the alarm system so sensitive in the first place.
While professional support is often the most effective path for chronic anxiety, there are small daily habits that can help calm an overactive nervous system between sessions:
None of these replace professional support, but they can be a helpful start while you consider what ongoing care might look like.
If you recognise yourself in any of this, it does not mean something is wrong with you. It means your nervous system has adapted, perhaps too well, to a world that asks a great deal of it. Anxiety in 2026 often has less to do with personal failure and more to do with an ancient alarm system trying its best to keep you safe in a modern world it was never designed for.
