Sleep Diary Template: Track and Improve Your Rest
In this article: A simple, printable sleep diary template that helps you identify what’s actually disrupting your sleep — and how to fix it with data, not guesswork.
Why a Sleep Diary Works
Sleep trackers give you data. A sleep diary gives you context.
A tracker tells you: “You woke up at 3 AM.” A diary tells you: “You woke up at 3 AM after eating spicy food at 9 PM and having an argument before bed.”
That context is everything. It’s the difference between knowing you have a problem and knowing why you have a problem.
Sleep diaries are the #1 tool recommended by sleep specialists for diagnosing insomnia. Not fancy gadgets. Not apps. A simple log of what you did, when you did it, and how you slept.
The Sleep Diary Template
Use this template every morning for at least 2 weeks. Fill it out within 30 minutes of waking, while the night is still fresh.
Evening Entry (Before Bed)
| Question | Your Answer |
|---|---|
| Caffeine today? | What, when, how much |
| Alcohol today? | What, when, how much |
| Exercise today? | What, when, how intense |
| Dinner time? | What time |
| Dinner content? | What did you eat |
| Screens stop time? | When did you last use screens |
| Stress level (1-10)? | How stressed were you today |
| Bedtime routine? | What did you do in the last hour before bed |
| Bedtime? | What time did you get into bed |
Morning Entry (After Waking)
| Question | Your Answer |
|---|---|
| Lights out time? | What time did you turn off the lights |
| Sleep onset? | How long to fall asleep (estimate) |
| Night awakenings? | How many times, how long each |
| Final wake time? | What time did you wake up for good |
| Out of bed time? | What time did you get out of bed |
| Sleep quality (1-10)? | How would you rate last night’s sleep |
| Daytime energy (1-10)? | How energized do you feel today |
| Dreams? | Any notable dreams (brief note) |
| Notes? | Anything unusual or noteworthy |
How to Use the Diary
Step 1: Print or Copy the Template
Print multiple copies, use a notebook, or create a digital spreadsheet. The format doesn’t matter — consistency does.Step 2: Fill It Out Every Morning
Don’t skip days. Don’t fill it out at night (your perception changes). Do it first thing in the morning.Step 3: After 2 Weeks, Look for Patterns
Ask yourself:
Timing patterns:
Disruptor patterns:
Improvement patterns:
Step 4: Make One Change at a Time
Based on your patterns, change one thing for the next 2 weeks:Step 5: Track the Change
Keep the diary going. Compare your sleep metrics before and after the change. Did it help? Keep it. Didn’t help? Try something else.What to Look For

The TCM Perspective
TCM practitioners have always asked detailed questions about daily habits — not just sleep. They understand that sleep is the result of everything that came before it.
What you eat, when you eat, how you move, what you feel, when you rest — all of it culminates in how you sleep.
A sleep diary is a modern version of this holistic assessment. It connects the dots between your daily choices and your nightly rest.
The Bottom Line
You can’t improve what you don’t measure. A sleep diary is the simplest, cheapest, most effective way to understand your sleep patterns.
Print the template. Fill it out every morning for 2 weeks. Find your patterns. Make changes. Track results.
It’s not glamorous. It’s not high-tech. But it works.
