Therapy Thursday: Why We Need Other People to Calm Our Nervous Systems…

One of the things I love most about being a therapist is watching people discover that there is actually a name for something they’ve experienced their entire lives. They’ll describe a feeling or a pattern they’ve noticed and then look at me almost relieved when I tell them, “There’s a reason that happens.” Suddenly what felt confusing starts to make sense. That’s one of the reasons I wanted to start this Therapy Thursday series. There are so many concepts we use in therapy that sound overly clinical or intimidating, but when you strip away the jargon, they’re really just explanations for what it means to be human. So I thought we’d start with one of my favorites: co-regulation.

Most of us have experienced co-regulation hundreds, maybe even thousands, of times without ever realizing it. Think about the last time you were overwhelmed and someone you trusted simply sat with you. They didn’t have the perfect advice. They didn’t solve your problem. They weren’t especially profound. They were just… there. Maybe they listened while you cried. Maybe they put a hand on your shoulder. Maybe they reminded you to breathe or wrapped you in a hug. And somehow, almost without noticing it, your breathing slowed down. Your shoulders relaxed. Your thoughts became a little less chaotic. Nothing about your circumstances had changed, yet somehow your body had.

That’s co-regulation.

One of the biggest misconceptions people have about emotional health is believing that emotionally healthy people regulate themselves all the time. We tend to think that maturity means needing no one, that strength means handling everything alone, and that asking for comfort somehow means we’ve failed. I hear it in my office almost every week. “I know I shouldn’t need people this much.” “I should be able to calm myself down.” “I hate that I get emotional.” Somewhere along the way, many of us learned that dependence and weakness were the same thing.

But our nervous systems tell a very different story.

From the moment we’re born, we rely on other people to help regulate our emotions because our brains simply aren’t developed enough to do it on our own. A newborn doesn’t know how to slow their heart rate when they’re scared or settle themselves after they’re startled awake. They borrow someone else’s calm. They are held, soothed, rocked, spoken to gently, and over time their tiny nervous system begins to settle because it’s responding to the safety of another human being. That’s not poor coping. That’s healthy development.

What’s fascinating is that our brains never completely outgrow that need.

As adults, we become better at regulating ourselves, but we never stop being influenced by the people around us. In fact, our nervous systems are constantly reading the environment, asking one simple question: “Am I safe?” We often think we’re evaluating situations with logic, but long before our thinking brain catches up, our body has already started answering that question.

Have you ever walked into a room where two people had obviously been arguing? No one had to explain what happened. You could feel it. The tension was almost tangible. Your own body became more alert before anyone even spoke. On the other hand, you’ve probably also met someone who has an incredible ability to make you feel safe almost immediately. They’re calm without being disconnected. Present without trying to fix everything. You leave conversations with them feeling lighter, even if nothing about your circumstances has actually changed.

That isn’t magic.

It’s biology.

This is one of the reasons therapy can be so healing, and honestly, it’s one of the things people don’t always expect. People often come into therapy thinking that the healing happens because I ask good questions or teach coping skills. Those things certainly matter, but they aren’t the whole story. Healing also happens because, week after week, someone sits with them without judgment. They experience what it’s feels like to have big emotions without someone becoming angry, dismissive, critical, or overwhelmed. Their nervous system begins collecting evidence that emotions don’t automatically lead to rejection or abandonment. Over time, their body starts believing something their mind has struggled to accept for years: maybe I’m actually safe here.

The same process happens outside the therapy office. It happens in healthy marriages where one partner chooses curiosity instead of defensiveness. It happens between parents and children when a parent remains steady during a tantrum instead of matching the child’s emotional intensity. It happens between close friends who know how to simply be present without trying to rescue each other. We are constantly influencing one another’s nervous systems, whether we realize it or not. Sometimes we spread anxiety. Sometimes we spread peace. Often we’re doing both without ever intending to.

I also think it’s important to acknowledge that not everyone grew up experiencing healthy co-regulation. Some people were raised by caregivers who were overwhelmed themselves. Others learned that emotions were met with criticism, anger, silence, or unpredictability. If no one ever helped your nervous system feel safe, it makes perfect sense that calming yourself feels incredibly difficult today. So many people assume there’s something wrong with them because they struggle with anxiety, emotional flooding, or shutting down during conflict. More often than not, what they’re experiencing isn’t a character flaw. It’s a nervous system that adapted to the environment it grew up in.

The encouraging part is that our brains continue learning throughout our lives. We aren’t limited by the experiences we had as children. Safe relationships have an incredible ability to reshape the way our nervous systems respond to the world. Every time someone stays present with you instead of walking away, every time someone responds with compassion instead of criticism, every time someone helps you feel seen instead of judged, your brain is quietly taking notes. It’s learning that not every difficult emotion ends in danger. It’s learning that closeness can exist without fear. Those moments may seem small, but over time they create profound change.

Eventually something beautiful begins to happen. The calm you once had to borrow becomes something you begin carrying within yourself. You recover from difficult moments a little faster. Conflict feels less threatening. Anxiety no longer controls every decision. And perhaps without even realizing it, you become that safe person for someone else. The regulation that was once given to you begins flowing through you to your children, your partner, your friends, your clients, or even a stranger who simply needed someone to sit with them for a few minutes.

I think that’s one of the most remarkable things about being human. We like to celebrate independence, but healing has always been deeply relational. We grow in relationships. We are wounded in relationships. And more often than not, we heal in relationships too. Understanding co-regulation isn’t just about learning a new psychological term. It’s about recognizing that needing other people isn’t evidence that you’re weak. It’s evidence that your nervous system is doing exactly what it was designed to do.

Maybe that’s the lesson I hope you’ll carry with you this week. If you’ve been struggling, don’t just ask yourself how you can calm down. Ask yourself who helps you feel safe. Sometimes healing doesn’t begin with finding the right technique. Sometimes it begins with finding the right people.
