Why this sleep tracker works
Bad sleep usually has a pattern hiding behind it — a too-late screen habit, a weekend rhythm that breaks the week. A few weeks of logging bedtime, wake time, hours and quality makes those patterns visible, so you can change what’s actually costing you sleep instead of guessing.
How to use it
- Print the PDF (US Letter or A4) and keep it on the nightstand.
- Each morning, fill in last night’s bedtime, wake time, hours and a quality score.
- After a couple of weeks, look for the patterns — and adjust the one habit doing the most damage.
