Why You React the Way You Do.

I’ve spent years studying the nervous system—the way our bodies and brains respond to stress, uncertainty, and even joy. Honestly, it fascinates me. I know, intellectually, that our fight, flight, or freeze responses are hardwired survival mechanisms. I know that the interplay between the sympathetic and parasympathetic nervous systems explains why sometimes a small trigger can feel like a tidal wave of emotion.

But knowing the theory doesn’t make living it any easier—especially when it’s your own body reacting in ways that feel unpredictable or frustrating. I notice it at home, at work, at a sports game with my kids, in fact, all the time. Maybe it’s a slammed door, a heavy sigh, an eye roll, or a quick text from one of my teens that cuts deeper than I might wish. Sometimes, my initial reaction is immediate: frustration, hurt, impatience, defensiveness. And even as a professional, I find myself thinking, “I shouldn’t be reacting like this. I know better.”

What I’ve learned, both in counselling, parenting, partnering, and in life is that our nervous system is always giving us information—sometimes in the form of tension in our shoulders, a racing heartbeat, or a tight jaw. These sensations are signals, not enemies. When I pause and notice them, I can choose how to respond rather than react. I can take a breath, step back, or even just acknowledge silently, “I see this is activating me. I can slow down.”

And this awareness doesn’t just benefit me. It benefits the people around me too. I’ve noticed that when I respond from a calmer place, even if my emotions are still present, those I’m interacting with can mirror that steadiness. They may still be upset, they may still push back, but there’s a subtle shift. When I can own my part in an interaction, the room feels less charged. Tension starts to ease. We can connect instead of collide.

Of course, this doesn’t always happen perfectly. There are definitely times when I react quickly, raise my voice, or match the intensity of the moment before I have a chance to pause. And then I have to repair. I apologize, I slow down, and I model the regulation I want to show. But over time, practicing this awareness - learning to notice my nervous system, recognize my triggers, and respond intentionally - has had a profound effect. It’s like building a muscle: the more I practice, the stronger my ability to pause, reflect, and respond with compassion has become.

The takeaway, for me and for anyone navigating the ups and downs of life, is this: our nervous system is not something to “fix.” The experiences we have are not there to be managed or erased. They are a guide. They tell us when we’re activated, when we’re shutting down, and when we’re capable of connection. And when we listen, pause, and respond thoughtfully, we create space for calm, curiosity, and understanding—not just for ourselves, but for everyone we interact with. And that, more than any theoretical knowledge, changes the quality of our relationships and our daily lives.
