I Was Today Years Old When I Learned… (Nervous System Edition)

There are moments when something clicks—and suddenly, the way you understand yourself shifts.

Many people are surprised to learn just how much the nervous system shapes their daily experiences.

What often gets labeled as “random anxiety,” “overreacting,” or “being too sensitive” is, in many cases, the nervous system doing exactly what it was designed to do—protect.

Here are a few insights that tend to shift how people understand themselves:

I WAS TODAY YEARS OLD WHEN I LEARNED...

Deep breathing is more than a relaxation tool

Slow, intentional breathing sends signals to the brain that the body is safe. This can help shift the nervous system out of a heightened stress response.

Anxiety isn’t random

Feelings of anxiety are often the result of a nervous system in a state of “high alert.” This response is not a flaw—it’s a protective mechanism that has become overactive.

Small actions can support regulation

Simple behaviors like humming, singing, or chewing gum can stimulate the vagus nerve, which plays a role in helping the body return to a more regulated state.

Grounding techniques help reset the brain

Practices like naming five things you can see are not just distractions—they help the brain reorient to the present moment and reduce overwhelm.

The body doesn’t always distinguish between types of stress

The nervous system can respond to everyday stressors—like emails or deadlines—in the same way it would respond to a physical threat. This is why certain situations can feel disproportionately intense.

Regulation is not about immediate calm

Self-regulation is not about forcing the body to calm down quickly. It’s about consistently creating a sense of safety, allowing the nervous system to gradually shift over.

Understanding the nervous system can change the way people relate to their thoughts, emotions, and behaviors. With this perspective, the focus shifts from “What’s wrong with me?” to “What is my body trying to communicate?”
