Micro pulse — roughly ninety seconds to three minutes
These sit between dense tasks when the next action is already known but the hands and eyes need a different surface. People often pair them with water, a stretch that does not require a mat, or a look out a real window instead of a second screen. The benefit we document is procedural: the calendar shows a tiny gap that used to collapse into the next meeting. We do not measure heart rate or stress chemistry; that is outside this public copy.
