The Nervous System Doesn’t Care if You’re in Aisle 5

​You’re in the cereal aisle. A child is screaming. A caregiver is flushed, frantic—fumbling with coupons, whispering warnings through clenched teeth.

You tense up too. Maybe you freeze. Maybe you look away. Maybe you feel that inner tug: Should I do something?

Here’s what’s happening: multiple nervous systems are activated all at once.

Stress is contagious. And in public spaces, it spreads fast. A child’s tantrum is often a visible sign that their nervous system is in distress. The caregiver’s brain responds, not with logic, but with urgency: Fix this. Now. Their heart rate speeds up. Their breath shortens. They might raise their voice—not out of cruelty, but because their nervous system is screaming for control.

When The Nervous System Goes On Overdrive

This is the sympathetic nervous system in action. It’s our body’s way of preparing for danger: fight, flight, or freeze. The nervous system doesn’t stop to consider whether the “danger” is a real threat or just a meltdown in aisle 5. It just reacts.

And when we, as bystanders, feel ourselves judging—or shutting down, or wanting to flee—that’s our nervous system talking, too. What looks like a mean tone, rudeness, or aggression is often something deeper: a human doing their best while having a stress response.

The brain is working overtime just to maintain control. Executive functioning—the part of the brain responsible for perspective-taking, patience, and problem-solving—is dialed down. Survival mode is dialed up. But here’s the good news: the parasympathetic nervous system can help us shift.

How To Take Back Control

It’s the part of our nervous system responsible for calming us down. It slows the heart rate, deepens the breath, and helps us access our more thoughtful, compassionate selves.

We can activate it on purpose—starting with how we breathe. It’s a simple, science-backed breathing pattern:

• Inhale through your nose

• Take a quick, second inhale

• Then exhale slowly through your mouth

This helps reset the body’s stress response. Once we’re regulated, we can respond instead of react.

And that’s when the magic happens. From a grounded place, we can offer a kind word. A warm glance. A small distraction for the child. Or a gentle, “You’ve got this,” for the caregiver.

These actions don’t take over the moment—they soften it. They offer the caregiver’s nervous system a chance to shift out of survival and back into connection.

We don’t have to fix the situations. But we can change the atmosphere. Because when we understand how stress shapes behavior, we replace judgment with empathy. And we make public spaces feel safer—for everyone.
