Understanding Your Nervous System with ADHD: Why Awareness Comes Before Change

One of the most common experiences I see in ADHD coaching and therapy is people trying to work out whether something about them is ‘good’ or ‘bad.’

Whether it’s procrastination, avoidance, scrolling, overworking, people pleasing, or another coping strategy, many people become trapped in a cycle of self judgement, often beating themselves up.

The problem is that judgement rarely creates lasting change.

Awareness does.

Moving Away From “Good” or “Bad”

Many of the strategies we develop throughout our lives exist for a reason.

They have helped us manage overwhelm, anxiety, boredom, low mood, social situations, uncertainty, or the everyday demands of life.

Rather than immediately asking, “How do I stop doing this?” I often encourage clients to first ask:

“What is this helping me with?”

When we become curious instead of critical, we can start to understand our choices more clearly.

From that place of understanding, we can decide whether a strategy still serves us or whether we’d like to build additional tools and options.

Change tends to happen more naturally when it comes from understanding rather than shame.

Understanding the Window of Tolerance

A concept I frequently use with ADHD clients is the Window of Tolerance.

This helps us understand the different states our nervous system moves through during the day.

Many people assume they are either anxious or calm, but there is much more happening beneath the surface.

Hyperarousal: The “On Edge” State

This can feel like:

* Racing thoughts

* Increased heart rate

* Restlessness

* Anxiety

* Feeling unsettled

* Being highly self-critical

* Feeling driven to constantly achieve or do more

Many ADHD adults spend significant periods in this state without recognising it.

They may appear productive on the outside while internally feeling under pressure or unable to switch off.

Hypoarousal: The Shutdown State

This can look like:

* Withdrawing from others

* Escaping into television, gaming, scrolling, or other distractions

* Low motivation

* Feeling disconnected

* Difficulty starting tasks

* Avoiding demands or social situations

This state is often misunderstood as laziness.

In reality, it is another survival response. The nervous system is attempting to reduce stimulation and conserve energy.

Regulation: The Safe State

When we feel regulated, we often notice:

* Greater focus

* Improved communication

* Emotional balance

* Comfortable connection with others

* Better access to our thinking skills

* More energy and capacity

The goal is not to stay regulated all the time.

The goal is to become more aware of when we move into survival states and learn how to support ourselves back towards safety.

Building Your Own Toolkit

One of the most important parts of ADHD therapy is recognising that there is no universal solution.

My role is not to tell clients how they should manage their lives.

Instead, we work together to understand how their nervous system operates, what triggers different states, and what helps them feel safe, connected, and capable.

As awareness grows, clients often discover that they already possess valuable information about themselves.

Together, we use that knowledge to build a toolkit that is designed specifically for them.

The goal isn’t to become someone else.

The goal is to understand yourself well enough to work with your brain and nervous system rather than constantly fighting against them.
