Heart pounding. Muscles burning. Lungs working hard to keep up. Nausea rising at the edges. If you are deep in a workout that is really working — a set you almost didn't finish, a final mile you almost didn't run — this is the best possible place to be. It is evidence that you pushed past the edge of comfortable and found something on the other side. Wake up in the middle of the night feeling the same way, and you are probably reaching for your phone to call someone — or wondering if you should go to the emergency department. Same body. Same sensations. Completely different experience. The signal did not change. What changed was the frame around it.

The Physiology Is Neutral

This is not a metaphor. It is literal biology. Your autonomic nervous system does not distinguish between the arousal of a hard effort and the arousal of a genuine threat. Epinephrine does not know the difference between a finish line and a crisis. The racing heart, the dry mouth, the narrowed attention, the feeling of something urgent and physical happening in your chest — these are outputs of the same system, triggered by the same cascade, expressing the same underlying state of high activation.

Consider anxiety and excitement. They are, from the body's perspective, nearly identical. Both produce elevated heart rate. Both quicken breathing and heighten sensory alertness. Both dry the mouth and tighten the stomach. Both send blood to the muscles and sharpen focus. Psychologist Alison Wood Brooks at Harvard has studied this extensively: people who reframe pre-performance anxiety as excitement — who tell themselves I am excited rather than I am anxious — perform measurably better on demanding tasks. Not because the physiology changes. Because the interpretation does.

The signal is the same. The frame determines what you do next.

What the ER Taught Me About Interpretation

In emergency medicine, I saw this played out in the most consequential possible setting. Patients would arrive in genuine distress — elevated heart rate, diaphoresis, chest tightness, shortness of breath — and the clinical question was never about the sensations themselves. It was always about context. What was happening before this started? What was this person doing? What is the story around these numbers?

The same vital signs that meant cardiac emergency in one patient meant panic attack in another, and dehydration in a third. The body was not lying in any of these cases. It was simply producing outputs that required interpretation. And getting the interpretation wrong had consequences.

Leaders face a version of this every day. The body signals high activation before a critical presentation, before a difficult conversation, before a decision with real stakes. And in that moment — in the gap between what the body is saying and how the mind responds — something important happens. You either catastrophize the signal, or you work with it.

Frame Shifting Is Not Positive Thinking

Frame shifting is the recognition that your initial interpretation of an experience is not the only possible interpretation — and that the interpretation you choose has real consequences for what you do next. It is cognitive, not cosmetic. It is asking: is this the only way to understand what is happening right now?

A leader walking into a high-stakes board presentation with a pounding heart is not in danger. They are activated. The activation is appropriate — it is the body doing exactly what it should do when something matters. The question is whether that leader interprets the activation as threat or as readiness. One frame produces constriction. The other produces resource. Same physiology. Radically different performance.

The same reframe is available in harder territory. A career transition that feels like loss can also be read as freedom. A conflict that feels like an attack can be held as an invitation to clarity. A period of uncertainty that feels like groundlessness can be understood as the particular discomfort of genuine growth.

How to Actually Do It

1  Notice the Interpretation, Not Just the Feeling

When you are in a state of high activation, pause long enough to separate the sensation from the story you are telling about it. Your heart is pounding: that is a fact. 'This means something is wrong' is an interpretation. The gap between the two is where the work begins.

2  Ask What Else This Could Mean

Not: what is the most optimistic possible reading? But genuinely: what are the other plausible interpretations? If anxiety and excitement produce identical physiology, which is actually the better description of this moment?

3  Choose the Frame That Gives You Agency

Not the frame that feels best — the frame that is both credible and useful. Threat frames constrict. Challenge frames expand. Between two reasonable interpretations, choose the one that gives you more room to move.

4  Practice It Before You Need It

The moments when frame shifting matters most are exactly the moments when it is hardest to access. Build the reflex in lower-stakes situations — the frustrating commute, the minor conflict, the physical discomfort of a hard workout — so that it is available when the cost is high.

The Frame Is a Choice

Viktor Frankl, writing from inside one of history's most extreme circumstances, observed that between stimulus and response there is a space — and in that space lies the freedom to choose. The stimulus does not determine the response. The interpretation does.

The body racing before something hard is not a warning signal. It is a readiness signal. The discomfort of a difficult conversation is not evidence that something is breaking. It is often evidence that something real is happening — that you are close enough to something that matters to feel it.
