Sleep Timing | 12 October 2025 | 2 min read

Plan bedtime for 5am to 7am wake-ups without guesswork.

Early mornings are easier when bedtime is mapped backwards from your fixed alarm using full cycles.

For a 6:00am wake-up, trial options around 9:45pm, 11:15pm, or 12:45am depending on your target cycles and buffer.

Keep your room cool, dim lights before bed, and avoid pushing bedtime too late on weekdays.

Occasional catch-up helps, but large weekday-weekend swings often increase fatigue.

Predictable bed and wake windows usually beat random long nights.
