Gratitude journals are everywhere, from notebooks to apps. The habit takes a few minutes and costs nothing, so it is worth asking honestly: does it work, and how much? Here is what the research shows.
Written by Vita Globe Editorial Team | Reviewed against peer-reviewed trials and meta-analyses
Does gratitude journaling improve mood?
A little. In a classic study, people who wrote down things they were grateful for each week reported feeling better about their lives than people who listed hassles or neutral events[1]. Meta-analyses find the effect on well-being and on symptoms of depression and anxiety is small to modest, and gratitude exercises did no better than other positive activities[2][3].
Caveat: Gratitude journaling is a nice habit, not a treatment. The researchers behind a 2021 meta-analysis recommended that people with depression or anxiety seek approaches with stronger evidence[3].

What did the original gratitude studies find?
The modern interest in gratitude journaling traces back to a 2003 set of experiments. Participants were asked to write down either things they were grateful for, daily hassles, or neutral events. In the first study, those in the gratitude group, who listed up to five things each week, rated their lives more favorably, felt more optimistic about the coming week, and reported exercising more than the other groups[1].
That study helped spark many others, so it is worth looking at what the bigger picture says.
How big is the effect, really?
When researchers pool many studies, the effect gets smaller and more nuanced:
- A 2016 meta-analysis found gratitude exercises improved well-being compared with doing nothing or doing a neutral activity, but performed about the same as other psychologically active exercises[2].
- A 2021 meta-analysis of 27 studies found gratitude interventions had a small effect on symptoms of depression and anxiety, and the effect was larger when compared with a waitlist than with an active comparison[3].
Put simply: gratitude journaling can help you feel a bit better, but it is not uniquely powerful, and part of the benefit may simply come from taking time to reflect. That is still worth something, especially for a habit that takes five minutes.
How do you start a gratitude journal?
You do not need a special notebook or app. What matters is making it easy to repeat:
- Pick a regular moment. The original study used a weekly entry[1]. Weekly is fine; daily is not required.
- Write three to five specific things. “My sister texted to check in after my appointment” works better than “family.”
- Include small moments. A good cup of coffee, a sunny walk, a kind coworker all count.
- Keep it short. Five minutes is plenty. A habit you enjoy lasts longer than one you dread.
- Pair it with something you already do, such as your Sunday evening planning or your morning coffee.
If you journal at night and your mind races with tomorrow’s tasks, the calm-down habits in our sleep and stress posts can help. Our guide to small, sustainable changes also covers how to stack new habits onto old ones.
What else can help your mood alongside journaling?
Since gratitude exercises work about as well as other positive activities[2], it makes sense to build a small toolkit rather than rely on one habit. Movement and time outdoors have their own evidence behind them, which we cover in exercise and mood and time in nature. And the basics still matter most: sleep, regular meals and people you can talk to.
The honest summary
- Writing down things you are grateful for can modestly improve well-being[1][2].
- Effects on depression and anxiety symptoms are small[3].
- It is free, low risk and easy to combine with other mood-supporting habits.
- If you are struggling with low mood, it is not a substitute for professional support.

Frequently asked questions
How often should you write in a gratitude journal?
The original 2003 study used weekly entries[1]. There is no proven ideal frequency, so choose what you can stick with, whether that is daily or a few times a week.
What should I write in a gratitude journal?
Write a few specific things, big or small, that you appreciated. Specific details, like who did what and why it mattered, tend to feel more meaningful than general lists.
Is gratitude journaling good for anxiety?
Meta-analyses found small effects on depression and anxiety symptoms[3] and little benefit for anxiety compared with other active exercises[2]. It is a nice habit, but anxiety that affects daily life deserves professional support. We also look at what the research shows on magnesium and anxiety.
Is it better to journal in the morning or at night?
Research has not settled this. Pick the time you are most likely to remember. Some people like it as an evening wind-down; others prefer it with morning coffee.
Does gratitude journaling work for everyone?
No habit works for everyone. Studies show average effects that are small to modest[3], so if it feels like a chore after a few weeks, try a different positive routine.
