What to log next to your mood: sleep, meals, movement

A mood rating on its own cannot explain itself. A four out of ten is just a four until something next to it says why. Log three facts alongside the number, how many hours you slept, when you ate, and whether you moved, and within a few weeks the low days start to line up with one of them. That is the whole method, and it takes under a minute a day.

None of this is about fixing mood. It is about context. The journal's job is to make patterns visible; what you do about them is a separate decision, and the journal will show you whether that worked too.

Sleep: the fact most likely to explain a low day

Write the hours slept and whether you woke in the night. That is two facts in about five words. "6.5, woke at 3" is a complete entry.

Sleep is worth logging first because it is the one that most often sits next to a low rating, and the one people most often forget to check. A run of low mornings after a run of short nights is not a mystery, but without the numbers side by side it feels like one.

If you want to see the shortfall as a total rather than night by night, our sister site Aura has a free sleep debt calculator. Put in a week of your logged hours and it shows how far behind you are. Seeing "nine hours down over the week" next to a week of low ratings tends to end the argument about whether sleep matters.

Meals: log the times, not the food

You do not need to record what you ate. Record when. Two or three times a day, to the nearest hour. "Ate 9, 13, 20" is enough.

Meal timing shows up in mood journals more often than people expect. A long gap in the afternoon can sit next to an irritable evening; a very late dinner can sit next to a bad night's sleep, which then sits next to a low morning. None of this is a rule. It is a pattern you can only see if the times are written down.

If you eat in a fixed daily window, or you are trying one, write the window's opening and closing times in the note for the first couple of weeks, so the journal can tell you how the days inside the window felt compared with the days before it. The team's fasting app, Fasted, keeps a free meal window planner that lays the window out against your day, and its article on fasting and sleep covers why a late window and a bad night often go together. Keep the mood side in your own journal and read the two next to each other.

Movement: yes or no, and one word

Did you move today? Yes or no, plus a word: "walk", "gym", "none". Do not log distance, minutes or steps. That is a fitness log, and it will make the mood entry take five minutes instead of one.

Movement is the fact with the clearest same-day link. A day with "walk" next to it is often rated higher than the day before without one, and that shows up within the first fortnight. What it will not show is a rule that works every day, because a walk on four hours' sleep is still a day on four hours' sleep. Read the three facts together.

The entry, in full

Here is what a complete entry looks like:

5/10. Slept 6, woke once. Ate 8, 13, 21. No movement. Long afternoon meeting, ate late, felt flat by evening.

Nineteen words plus a rating. It has everything a future you needs to explain the five.

Keep the format the same every day. Same order, same three facts. Consistency is what makes the page scannable later, and scanning is how you find the pattern.

Reading it after three weeks

After about three weeks, sort your days by rating in your head, or on paper, and read the three facts on the lowest five. One of the three will usually be doing most of the work. It is short sleep more often than not, but for some people it is the afternoon gap, and for some it is a run of "none" under movement.

Then pick one thing to change for the next two weeks, and keep logging. The journal now has a before and an after. That is the only evidence you will get that the change did anything, and it is better evidence than how you happen to feel on the day you check.

What not to do is add more fields. Caffeine, screen time, weather, social contact: each one is a fair question and each one makes the daily entry longer. Get three weeks of three facts first. If the low days do not line up with any of them, add a fourth then.

FAQ

How many things should I track next to my mood?

Three is enough: sleep, meals and movement. More than that and the entry takes too long to keep up daily. The value comes from the same three facts recorded every day, not from a long list recorded now and then.

Do I need to be exact about the times?

No. Hours slept to the nearest half hour, meal times to the nearest hour, movement as yes or no with a word. Rough numbers kept every day beat exact numbers kept for a week.

Will logging these things improve my mood?

Logging does not change mood by itself. It shows you which of the three tends to sit next to your low days, so you know what to try changing. Whether the change helps is something the journal will then show you too.
