Have you ever done something and thought, Why did I do that?
Perhaps you sent the message before you had really thought it through. Bought something you could not afford. Interrupted a conversation. Said something sharply, then wished you could take it back. Walked away from an opportunity because the feelings became too uncomfortable.
Sometimes impulsivity can feel as though your brain has sprinted ahead while the rest of you is still trying to catch up.
But what if the impulse is not the whole story?
What if, underneath the urge to act, there is an uncomfortable feeling, an unmet need or a nervous system asking for help?
The question I often return to is this:
Is it an impulse, or is it an SOS?
Impulsivity is not a character flaw
I want to begin here because so many people have been labelled by their impulsivity.
They have been called careless, selfish, dramatic, difficult, unreliable or attention-seeking. Over time, these words can become part of the way a person sees themselves.
But impulsivity is not proof that you are a bad person.
It is often a sign that something has happened very quickly inside you. Your emotions, thoughts, body sensations and urge to act can arrive almost at the same time. There may be very little space between feeling something and doing something.
That space is important.
When we are calm, rested and feeling safe, we may be able to pause, consider the consequences and choose how we respond. When we are overwhelmed, frightened, exhausted or emotionally flooded, that pause can become much harder to find.
This does not remove responsibility for our actions. It does, however, give us a more useful place to begin.
Instead of asking, “What is wrong with me?” we might ask, “What was happening inside me just before I acted?”
The nervous system can move faster than our thinking brain
Our nervous system is constantly scanning for what is happening around us and inside us. Is this safe? Is this threatening? Do I need to protect myself? Do I need to escape, defend myself or regain control?
When the nervous system senses danger , whether that danger is physical, emotional or connected to an old experience , it can move us towards action very quickly.
We might fight, flee, freeze or try to make the uncomfortable feeling disappear as fast as possible.
Impulsive behaviour can sometimes be part of that process. It may be an attempt to escape discomfort, find relief, gain stimulation or feel more in control.
This is particularly important for people living with ADHD. Impulsivity is one of the possible features of ADHD, alongside difficulties with attention and hyperactivity. The NHS explains that ADHD can affect a person’s ability to control impulses, and that support may include practical adjustments, talking therapies and, where appropriate, medication.
Understanding this does not mean every impulsive action is caused by ADHD. It means we can look beyond blame and consider how a person’s brain and nervous system may be working.
What might be underneath the urge?
An impulse can look simple from the outside. Someone spends money, walks out, shouts, drinks, overeats, sends a message or makes a sudden decision.
But the experience inside may be much more complicated.
Uncomfortable feelings
Sometimes the impulse is an attempt to move away from a feeling that seems too painful to stay with.
That feeling might be:
- Shame
- Rejection
- Anger
- Loneliness
- Boredom
- Anxiety
- Grief
- Fear of failure
- Feeling trapped or out of control
The action may offer temporary relief. For a moment, the emotional pressure drops.
But afterwards, the original feeling may return, accompanied by regret, guilt or self-criticism. This can create a cycle: discomfort, impulse, temporary relief, consequences and then more discomfort.
What feeling were you trying not to feel?
ADHD and the need for stimulation
For some people with ADHD, waiting can feel especially difficult. A delayed reward may not feel as compelling as something immediate. Boredom can become physically uncomfortable, and the brain may seek novelty, movement, conversation or sensation.
This is not laziness or a lack of care. It may be connected to the way attention, motivation and self-regulation work for that person.
A diagnosis should always come through an appropriate assessment. However, if impulsivity has been present across different parts of your life , perhaps since childhood , it may be worth speaking with your GP or a qualified professional about an ADHD assessment.
Trauma and learned protection
Trauma can teach us that things change quickly and that we need to respond quickly too.
If you have experienced danger, unpredictability or relationships where you had to stay alert, your nervous system may become highly sensitive to signs of threat. A tone of voice, a period of silence or a disagreement may trigger a response before you have had time to work out what is happening.
You may react, withdraw, please, attack or leave.
The response may once have helped you survive. But does it still fit the situation you are in now?
Overwhelm
Sometimes there is no single dramatic trigger. There is simply too much.
Too many demands. Too much noise. Too many decisions. Too little sleep. Too much responsibility and not enough recovery.
When the system is already overloaded, a small event can feel enormous. The impulse may be the final expression of a body and mind that have been carrying more than they can manage.
Building a pause , without expecting perfection
A pause does not have to be long. In the beginning, it may only be one breath.
We sometimes imagine emotional regulation as being able to remain completely calm. I do not think that is realistic. To me, regulation is less about never becoming overwhelmed and more about noticing what is happening a little earlier.
Notice the first signal
Before an impulse becomes an action, there may be early signs:
- Your chest feels tight
- Your breathing changes
- Your thoughts speed up
- You feel hot, restless or numb
- You begin rehearsing what you want to say
- You feel an urgent need to decide immediately
- You notice the thought, “I have to do this now”
These signals are not failures. They are information.
You might quietly say to yourself, “Something is happening in me right now.”
Use a time-buying phrase
If you are in a conversation, you do not have to respond immediately.
Try:
- “I need a moment to think.”
- “I want to come back to this when I am calmer.”
- “I have heard you. Let me take some time.”
- “I am not ready to decide right now.”
A sentence like this can create enough space for your body to settle and your thinking to catch up.
Make the pause physical
If possible, change something in your environment.
Put the phone down. Step into another room. Drink some water. Walk around the block. Place both feet on the floor and notice what is supporting you.
A physical pause can be more effective than telling yourself to “just calm down”, especially when your thoughts are moving quickly.
Ask three gentle questions
When the urge arrives, try asking:
- What am I feeling?
- What do I need right now?
- What might happen if I wait ten minutes?
You may still decide to act. The aim is not to control every thought or urge. The aim is to make the action more conscious.
What if the pause comes after the action?
This matters too.
Many people think they have failed because they only understand what happened afterwards. They see the pattern once the argument has ended or the purchase has been made.
But reflection after an event is still valuable.
Rather than attacking yourself, try looking back with curiosity:
- What happened immediately before the impulse?
- What was I feeling in my body?
- What story was I telling myself?
- What did the action give me for a few moments?
- What were the consequences?
- What might help me next time?
Self-understanding is not the same as excusing harmful behaviour. It is what allows us to take responsibility in a way that leads to change rather than shame.
When can therapy help?
Therapy can help when impulsivity is affecting your relationships, finances, work, safety or sense of self.
Together, we can explore the pattern beneath the behaviour. We might look at childhood experiences, trauma, ADHD, anxiety, emotional regulation, boundaries or the beliefs you hold about yourself.
Therapy can also help you practise practical strategies for creating a pause. Depending on your needs, this may include elements of cognitive behavioural therapy, grounding, emotional awareness and nervous-system regulation.
If ADHD may be part of the picture, therapy cannot replace a formal assessment or medical advice. The NHS provides information about ADHD support and talking therapies, and your GP can help you consider appropriate next steps.
You are more than your fastest reaction
There may be moments when your brain wants to sprint.
That does not mean you are beyond help. It may mean that something in you is activated, overwhelmed or asking to be understood.
The next time an urge arrives, see whether you can meet it with a little curiosity before judgement.
Not, “What is wrong with me?”
But:
Is this an impulse, or is it an SOS?
And if it is an SOS, what might that part of me be trying to tell me?
