What a mood journal is, what research says about it, how to keep one in five minutes a day, plus a free template, 12 prompts and a weekly review.

A mood journal is a short daily log where you rate how you feel, name the emotion and jot down a few lines about what's behind it. It takes about five minutes. After a few weeks, you can look back and see what lifts your mood, what drags it down and what you'd never have noticed otherwise.
Below: what a mood journal is, what the research says, how to keep one, a free template you can copy, and how to spot patterns.
It's a cross between a mood tracker and a diary. Here's how they compare:
| Mood tracker | Mood journal | Diary | |
|---|---|---|---|
| What you record | A rating, color or emoji | A rating plus a few lines on why | What happened, in as much detail as you like |
| Time it takes | Seconds | 2–5 minutes | 10 minutes or more |
| Best for | Seeing trends at a glance | Understanding what drives your mood | Remembering and processing events |
A tracker tells you that Tuesday was a 3. A mood journal tells you it was a 3 because you slept five hours and had a tense meeting. That "because" is what makes patterns visible. If you'd rather start with just the numbers, here's how to make a simple mood tracker.
Research suggests it can, mostly by making you more aware of your emotions. The effects are modest, though, and it isn't a treatment.
The takeaway for your journal: don't just vent. Name the feeling, then add a line about what you think is behind it.
Copy this into a notebook or your notes app and fill it in once a day:
| Field | What to write | Example |
|---|---|---|
| Date and time | When you're writing | Tue, 9:30 p.m. |
| Mood (1–10) | Your gut rating | 4 |
| Feeling words | One to three precise words | Drained, a bit anxious |
| Energy | Low, medium or high | Low |
| Sleep last night | Roughly how many hours | 5.5 |
| What happened | The main event or two | Long meeting ran over, skipped lunch |
| What I made of it | Your thoughts about it | Worried my manager thinks I'm behind |
| What helped | Anything that lifted things | Call with my sister |
| For tomorrow | One small thing | Eat lunch away from my desk |
Skip any field that doesn't fit the day. A half-filled entry is better than none.
When the template feels like too much, answer one of these instead.
On good days
On hard days 5. When did my mood drop, and what happened just before? 6. What am I telling myself about it? Is that the whole story? 7. What's one thing that helped, even a little? 8. What do I need right now: rest, company or a plan?
On flat or confusing days 9. If my mood were weather, what would it be? 10. Is this tiredness, boredom, sadness or something else? 11. What have I been avoiding? 12. What's one feeling I haven't named yet?

The real value shows up when you look back. Once a week, read your entries and ask:
Write one line at the bottom: "This week I noticed…". Over a month, those lines turn into a clear picture you can act on, or share with a doctor or therapist.
Any of them works. Paper is screen-free and good for bedtime. A notes app is always with you. An app does the pattern-spotting for you, which matters, because that's the step most people skip. We compared options in our roundup of the best mood tracker apps.
In WTMF, mood tracking takes two taps, and the written part is optional, so you can log a quick rating on busy days and write more when you want. Over weeks it shows visual patterns. For longer entries, AI journaling reflects and asks questions only if you opt in, with no streaks to keep up. Both are encrypted and never used to train models.
A mood journal is a self-awareness tool, not a diagnosis. If your entries keep landing on words like empty, hopeless or worthless, or your mood is getting in the way of daily life, it's time to talk to someone. NIMH advises seeking professional help if you have severe or distressing symptoms that have lasted two weeks or more. Bringing your journal along can make it easier to describe what's been going on.

Tonight, try one entry: a number, a feeling word and one line about why. That's a mood journal.
A mood journal is a short, regular log where you rate how you feel, name the emotion and write a few lines about what's behind it. It sits between a mood tracker, which records a number, and a diary, which records events.
Keep it short: a 1–10 rating, one or two feeling words, what happened, what you made of it, and a couple of factors like sleep or exercise. A sentence or two for each is enough.
They overlap. A mood tracker usually records a rating or color so you can see trends. A mood journal adds a few written lines, which helps you understand why a day went the way it did.
Once a day is a good default, at a consistent time. If that's too much, a few times a week still builds a useful picture. What matters most is doing it long enough, at least a few weeks, to see patterns.
