An Evening Routine That Works

An ordered wind-down procedure with exact timings: last caffeine, last meal, screens off, lights down.

An evening routine works because it is ordered and timed, not because any single step is magical. The sequence below assumes an 11 pm lights-out; shift every step if your bedtime differs. The four checkpoints are last caffeine, last meal, screens off, and lights down — each with a specific cut-off time rather than a vague suggestion.

Last caffeine comes first because it has the longest reach. Caffeine has a half-life of about 5 to 6 hours, so an afternoon coffee can still affect night sleep. Working backwards from 11 pm, the last caffeine should be no later than about 3–5 pm — earlier if you are sensitive or already sleep poorly. Tea, cola, energy drinks and dark chocolate all count toward the same budget.

Last meal sits two to three hours before bed: a heavy meal close to bedtime diverts digestion into the first sleep cycle, while going to bed hungry can wake you. Screens come next: blue-enriched light from screens in the evening suppresses melatonin and delays sleep onset, so devices go off 60–90 minutes before bed. Finally, lights down — dim the household lights 30–60 minutes before bed so your body gets the darkness signal early.

The most common failures are predictable: caffeine 'just this once' at 6 pm, screens in bed 'for five minutes', and a weekend wake-up two to three hours later than weekdays. Each one individually seems small; together they undo the week. Vigorous exercise is a fourth: regular physical activity improves sleep quality, but vigorous sessions are best finished a few hours before bed because the residual rise in body temperature can delay sleep onset.

Follow the order for two weeks before judging the result. Sleep hygiene compounds — one variable at a time rarely produces a visible change, but the full set does. Keep the same wake-up time every day, including weekends, even if the evening routine slips; the fixed morning anchors the circadian rhythm more firmly than any single evening habit.

• 16:00 — last caffeine of the day (5–6 hours before bed).
• 18:00–18:30 — last substantial meal, 2.5–3 hours before bed.
• 19:00–20:00 — finish vigorous exercise, at least 3–4 hours before bed.
• 21:00 — dim household lights.
• 21:30 — screens off: phone, tablet, laptop (60–90 minutes before bed).
• 22:00–22:30 — lights down: reading, stretching, quiet routine.
• 23:00 — lights out; bedroom at about 18 °C (65 °F), dark and quiet.
