I started walking in the morning (within an hour of waking, though supposedly within thirty minutes is even better, don’t know evidential base) and found myself sleeping less and waking earlier more consistently and feeling tired around the same time more consistently. From ~averaging 8.5 down to 7.5. Sometimes I wake really early, around sunrise, and find myself wanting a nap in early evening. This was very notable for me after decades of sleep problems and hating hating hating sleep interventions.
