How to Recognise When Your Body Is in Fight‑or‑Flight

Most of us imagine fight-or-flight as something obvious. We picture panic attacks, racing hearts or running away from danger. In reality, it often looks much quieter than that. It can look like always being busy, struggling to switch off, feeling guilty for resting, or constantly telling yourself you're "fine" while your body quietly disagrees.

For years, I had no idea my nervous system was living in survival mode. I wasn't someone who considered myself anxious. I was still going to work, ticking off my to-do list and carrying on with life. If anything, I thought I was coping pretty well. Looking back now, I can see my body had been trying to get my attention for a long time—I just wasn't very good at listening.

Fight-or-flight isn't a personality type or a mindset. It's one of the body's most intelligent survival mechanisms. When your brain senses a threat, your nervous system automatically prepares you to deal with it. Your heart rate increases, stress hormones like adrenaline and cortisol are released, digestion slows down and your muscles prepare for action. It's an incredible system when you're facing genuine danger.

The problem is that our bodies don't only respond to physical threats. They also respond to chronic stress, difficult relationships, burnout, grief, uncertainty, constantly putting everyone else first, or living in environments where we never quite feel safe. Over time, your nervous system can become so used to being switched on that it starts to believe this is your normal.

You might notice yourself feeling tired but unable to relax, struggling to sleep, dealing with digestive issues, carrying tension in your shoulders or jaw, overthinking every decision, people-pleasing, or feeling strangely guilty every time you stop to rest. Some people experience changes in appetite, recurring headaches, heart palpitations or unexplained weight loss. None of these symptoms automatically mean you're living in fight-or-flight, but together they can begin to paint a picture.

That was certainly true for me. My health deteriorated, I lost a significant amount of weight, and my body kept giving me little nudges that something wasn't right. At the time, I brushed most of them off. I thought I just needed a holiday, a better routine or to be a bit less stressed. In hindsight, my body had probably exhausted every other way of getting my attention.

One of the biggest things I've learned is that healing isn't about forcing yourself to relax. If you've ever told yourself to "just calm down" and found it completely impossible, you're not failing. Your nervous system isn't responding to logic; it's responding to whether it feels safe. That's why healing often happens through consistent experiences rather than one magical breakthrough.

For me, those experiences were surprisingly ordinary. Spending more time in nature. Eating meals that actually nourished me. Moving my body because it felt good rather than because I had to. Laughing with friends. Travelling. Dancing around my kitchen. Doing more of the things that reminded me life wasn't just about getting through the day.

The beautiful thing about our nervous systems is that they're adaptable. Just as they learn stress, they can also learn safety. That doesn't happen overnight, and it doesn't mean life suddenly becomes perfect. It simply means that, over time, your body starts to realise it doesn't have to stay on high alert all the time.

If there's one thing I hope you take away from this, it's that you don't need to fight your body. More often than not, it's been trying to help you all along. Sometimes the kindest thing we can do is slow down long enough to ask what it's been trying to tell us—and then give ourselves permission to build a life that feels calmer, lighter and a lot more enjoyable.
