When Your Nervous System Thinks There's a Bear in the Room

Have you ever found yourself reacting to something small in a surprisingly big way?

Your spouse asks an innocent question. A coworker sends a brief email. Your child spills a glass of milk. Someone cuts you off in traffic.

Before long, you're far angrier, more anxious, or more withdrawn than the situation seems to warrant. A little while later you find yourself wondering,

"Where did that come from?"

One possible answer is surprisingly simple: What if your nervous system believed there was a bear in the room?

The Bear Isn't Always a Bear

Imagine for a moment that there really was a bear standing in your living room. Would you be able to calmly discuss your weekend plans? Would you thoughtfully consider another person's point of view? Would you patiently fold the laundry? Probably not.

Your brain and nervous system would be focused on one thing: survival. Thankfully, most of us don't encounter many bears (unless you're in northern Ontario, that is!). The challenge is that our nervous system doesn't only respond to physical danger. Sometimes a painful memory, a difficult conversation, unexpected criticism, financial stress, sensory overload, or simply an exhausting week can trigger the same protective response.

The bear isn't actually in the room. But your nervous system may believe it is.

Fight, Flight, Freeze... or Fawn

When our nervous system detects danger, it prepares us to survive. Psychologists often refer to these protective reactions as the fight, flight, freeze, or fawn response.

Sometimes that looks like fight—raising our voice, becoming defensive, or snapping at someone we love.

Sometimes it looks like flight—avoiding a difficult conversation or distracting ourselves from uncomfortable feelings.

Sometimes we freeze—our minds go blank, we can't make a decision, or we feel completely stuck.

Others respond by fawning—trying to keep everyone else happy in hopes of staying safe.

None of these responses necessarily mean something is wrong with you. More often, they tell us that our nervous system is trying to protect us in the best way it knows how.

Understanding this doesn't remove responsibility for our behaviour. It simply gives us a place to begin responding with greater wisdom and compassion.

Your Nervous System Needs Time

One of the things many people don't realize is that our nervous system doesn't simply switch off the moment the stressful event is over. Even after the "bear" has disappeared, our bodies often need time to recognize that we're safe again. Stress hormones and heightened physiological arousal gradually settle, but they don't disappear instantly. Depending on the situation, it may take twenty minutes or more before we begin to feel fully regulated again. That helps explain why the drive home from work matters.

If you've spent the day dealing with conflict, deadlines, or difficult people, you may walk through your front door while your nervous system is still preparing to fight the bear. Your family isn't the threat. They're simply meeting you before your nervous system has realized the danger has passed.

Some Nervous Systems Work Harder Than Others

For some people, these periods of heightened alertness are occasional. For others, they are much more frequent. Many people living with post-traumatic stress, chronic anxiety, or forms of neurodivergence experience a nervous system that works especially hard to monitor the world around them. Sometimes that's because of past experiences. Sometimes it's because everyday environments demand far more energy than others realize.

That doesn't mean they're broken. It means their nervous system has become especially vigilant, often for very understandable reasons. Recognizing this isn't about making excuses. It's about replacing shame with understanding so that meaningful change becomes possible.

Creating Space Between the Bears

One of the healthiest habits we can develop is creating small transitions between stressful moments. Instead of walking straight from a difficult meeting into family life, take a few minutes. Sit quietly in your car. Take several slow breaths. Notice the trees outside your window. Listen to a favourite song. Walk around the block. You're not wasting time. You're giving your nervous system an opportunity to recognize that the bear is no longer in the room.

🛠 Try This

The next time you notice yourself becoming overwhelmed, try this simple reset.

Place both feet on the floor. Take one slow breath in. Breathe out even more slowly.

If possible, splash some cool water on your face or hold something cool against your cheeks or the back of your neck for a few moments. Many people find this helps interrupt the stress response and gives the nervous system another signal that it's safe to begin settling.

Then quietly ask yourself: "What is my nervous system trying to protect me from right now?"

You don't need to have the perfect answer. Simply becoming curious is a powerful place to begin.

Sometimes our nervous system has been protecting us for so long that it becomes difficult to recognize when we're safe. Therapy can provide a space to gently explore those patterns with curiosity and compassion, helping us respond more intentionally rather than simply reacting automatically.
