The Thayer Matrix maps four brain-body states according to two dimensions, energy and tension, helping us recognize and understand shifts in our internal state.
Developed from Robert Thayer’s work on mood and arousal, the Thayer Matrix maps four brain-body states through two interacting dimensions: energy and tension. High or low energy can occur alongside high or low tension, producing very different states and experiences. In Self-Reg, the Matrix helps us move beyond a simple regulated/dysregulated or calm/stressed binary and become more precise about what is happening internally. Energy and tension are grounded in underlying physiological processes and change throughout the day. The Matrix is particularly important to Reflect, because learning to recognize these shifts strengthens stress-state awareness and helps us discover what moves us toward or away from restoration.
Consider four familiar experiences: energized and relaxed, energized and tense, tired and relaxed, or tired and tense. Being exhausted but unable to settle is very different from being peacefully tired. Feeling excited and ready to engage is different from being highly energized and on edge.
The Thayer Matrix gives us language for these differences by looking at energy and tension together. Over time, we can begin noticing where we are in the Matrix, what moved us there, and what actually helps.
This makes internal state something we can become curious about rather than simply labelling ourselves calm, stressed, good, or bad.
Energy and tension together tell us far more about our state than “calm” or “stressed” alone.
Hear Stuart explore why energy and tension need to be understood together when we think about stress and state.
