A client once described lying on the couch, doing nothing, and feeling her chest tighten within ninety seconds. "It felt like I was doing something wrong," she said. She wasn't. Her body simply didn't have a category for "safe and unproductive" — every stretch of stillness in her history had either preceded a demand, or followed a collapse. Nothing in between.

The body doesn't rest on command

Willpower can make you lie down. It can't make your nervous system believe it's allowed to. If your history taught your body that stillness is dangerous, unproductive, or the calm before a storm, then rest will keep triggering the same bracing a threat would — quietly, but measurably.

What actually rebuilds the tolerance

This is a capacity, not a mood

You don't need to feel calm to practice rest tolerance. You need repetition. The feeling comes later, once the body has enough evidence that stillness doesn't cost anything.

Rest isn't the absence of effort. For a bracing body, it's a skill — and skills are built through repetition, not intention.
