Sleep Checklist

Good sleep is not built in the 30 minutes before bed — it is laid down across the whole day. The Restcalc Sleep Checklist walks from your afternoon caffeine cutoff to lights-out, so nothing important gets missed.

Why a full-day plan

Caffeine, light, food, and activity during the day all shape that night's sleep. A bedtime-only checklist misses the biggest levers — like that 4 pm coffee still in your system at 10 pm.

The checklist spreads the work across the day so bedtime is just the easy final step.

The phases, briefly

Day: fixed wake time, morning light, daytime activity, smart napping. Afternoon: caffeine cutoff. Evening: food, alcohol, gentle movement. Two hours before: light, bath, lower cognitive load. One hour before: screens, excitement, fluids, calm activity. Bedside: darkness, quiet, temperature, phone away. Weekly: log and protect the bed = sleep cue.

Each item carries a one-line "why" so the habit actually sticks.

The caffeine science

Caffeine is absorbed within about 45 minutes and its typical half-life is around 5 hours — and can stretch past 10 in sensitive people. That 4 pm cup can still be blocking adenosine receptors at bedtime. The Caffeine Cutoff Calculator sets your personal last-cup time.

Cutoff by sensitivity: low 8h, normal 6h, high 10h+ before bed.

Light and temperature

Bright morning light sets the clock; dim, warm light in the last hour lets melatonin rise. A cool room (around 18°C / 65°F) supports deep sleep.

These are cheap, high-impact tweaks the checklist keeps in front of you.
