How to Fix a Broken Sleep Schedule
A practical guide to regular timing, light exposure and habits that support a more consistent sleep-wake schedule.
Anchor the clock
Regular wake time, appropriately timed light exposure and consistent routines are core levers for sleep-wake timing. Large, repeated swings in timing can make consistency harder.
A practical decision framework
Start by defining the actual outcome you want: falling asleep, staying asleep, shifting a schedule, reducing bedtime stimulation, or evaluating a commercial product. Those goals can have different evidence and different next steps. Avoid assuming that one ingredient or one habit solves every sleep problem.
What the evidence standard should be
Strong claims need strong evidence. Mechanism explanations, testimonials and ingredient-level studies can generate hypotheses, but they do not automatically prove that a finished supplement treats a sleep disorder. We prioritize authoritative guidance and distinguish merchant statements from independent evidence.
