Physical Activity Timing

Movement supports daytime alertness. Timing matters for how your body prepares for rest later.

Morning Movement

A brief walk or light stretching within two hours of waking reinforces the active phase. Even ten minutes of movement counts as a valid cue.

Evening Boundary

Finish vigorous exercise at least three hours before your target bedtime. Gentle stretching or a slow walk is acceptable closer to wind-down time.

Wind-Down Boundaries

The hour before sleep sets the tone for how easily you transition to rest.

Combine Cues With Your Anchor

Select two to three cues from each category rather than attempting all at once. Pair them with the anchor time defined in the Rhythm Matrix. Review effectiveness after two weeks and adjust one cue at a time.
