Three systems behind our feelings
Our emotions are shaped by three systems that evolved to keep us safe and well. They are often pictured as three colours: red for threat, blue for drive, and green for soothe. We need all three, and the aim is balance, not getting rid of any one of them.
The threat system (red)
This system protects you. It scans for danger and gives you feelings like fear, anxiety, and anger so you can react fast. It is powerful and quick because, long ago, missing a threat could be deadly. It is doing its job even when the danger is a worry or a harsh thought, not a real tiger.
The drive system (blue)
This system motivates you. It pushes you to want things, chase goals, and feel the buzz of achieving or winning. It gives energy and excitement and helps you get things done. On its own, though, it can leave you always reaching for the next thing and never quite satisfied.
The soothe system (green)
This system settles you. It brings feelings of calm, contentment, safeness, and connection with others. It is the feeling of resting when there is nothing to fear and nothing to chase. It is linked to kindness, warmth, and feeling cared for, and it helps the other two systems calm down.
When the systems get out of balance
Busy modern life and a habit of self-criticism tend to over-feed the threat and drive systems and starve the soothe system. We push hard, worry a lot, and rarely let ourselves rest or feel cared for. This is not a personal failing; it is a very common pattern. Compassion is the deliberate practice of building the soothe system back up so the three come into balance.

Small ways to feed the soothe system
The soothe system grows with practice. Warmth, kindness, slow breathing, and connection all help. Tick any you would like to try more often.

When to use The Three Emotion Systems
The Three Emotion Systems is an interactive cognitive behavioural therapy (CBT) worksheet. As a core CBT skill it is used right across the model, with presentations including depression, anxiety, OCD, trauma and low self-esteem, rather than being tied to a single diagnosis.
It is designed to be used within therapy rather than as a standalone self-help tool: a therapist introduces it, works through it collaboratively, and helps make sense of what it surfaces. You can preview the full worksheet above, then assign it digitally for clients to complete between sessions on any device — or download it as a print-ready PDF.

Completed on the Formulate platform, your client's answers are saved automatically and shared straight back to you, so you can review them before the next session rather than waiting for a paper copy to come back.
The CBT approach behind it
In common with other CBT methods, The Three Emotion Systems works by building a kinder, more balanced relationship with oneself (compassion-focused work). The aim is not positive thinking but a clearer, shared understanding of what keeps a difficulty going — and practical, testable ways to change it.
Because it is a CBT tool it stays focused on the here-and-now links between thoughts, feelings, the body and behaviour, and it works best as one part of a wider course of therapy rather than as advice or a diagnosis.
