Journaling before bed can help you sleep, especially if a busy mind keeps you awake. The best-studied approach is surprisingly simple: spending about five minutes writing a specific to-do list for tomorrow helped people fall asleep faster in a sleep lab study. Writing down a few things you feel grateful for is also linked to calmer thoughts at bedtime and better sleep. The key is to keep it short and gentle, so it clears your head rather than stirring it up.
If you lie down and your mind starts listing everything you need to do, this is one of the easiest habits to try.
Does journaling before bed help you sleep?
The clearest evidence comes from a 2018 study by Michael Scullin and colleagues, published in the Journal of Experimental Psychology: General. Healthy adults spent the night in a sleep lab. Before lights out, half spent five minutes writing a to-do list of tasks they needed to do in the coming days. The other half wrote about tasks they had already completed.
The to-do list group fell asleep faster. And the more specific their lists were, the faster they tended to fall asleep. The researchers suggested that writing down unfinished tasks helps “offload” them, so the mind no longer has to keep rehearsing them in the dark.
That matches a very common experience. It is often not big worries that keep people awake, but a steady trickle of small reminders: the form to sign, the message to send, the thing to buy. Putting them on paper gives them somewhere to go. We explore this loop in more depth in how to stop racing thoughts at night.
Does gratitude journaling help sleep?
There is encouraging evidence here too, though it comes from smaller or different kinds of studies.
In 2009, Alex Wood and colleagues published a study in the Journal of Psychosomatic Research involving 401 adults. People who were more grateful in general tended to sleep better: they fell asleep more easily, slept longer and reported better sleep quality. The link seemed to work through what people were thinking about as they fell asleep. Grateful people had more positive and fewer negative thoughts at bedtime. This was a survey study, so it shows a link rather than cause and effect.
A small pilot trial by Nancy Digdon and Amy Koble (2011, Applied Psychology: Health and Well-Being) tested short evening exercises, including writing about things to be grateful for, in 41 people. Each of the techniques they tried reduced worry and pre-sleep arousal and improved sleep compared with the week before. The trial was small and did not have a separate control group, so it is best seen as a promising early finding.
Put together, the research suggests that what you think about as you settle down matters, and a few gentle lines of gratitude can tilt those thoughts in a calmer direction.
What should I write in a journal before bed?
You do not need a special notebook or a long routine. Two kinds of writing have the most support:
1. A specific to-do list for tomorrow. Write down the tasks on your mind, as specifically as you can. “Email Sam about Friday” is better than “work stuff”. Specific items seem to be easier for the mind to let go of.
2. Three small things you are grateful for. These do not need to be profound. A warm drink, a kind message, ten quiet minutes. Small, real moments work well.
A few gentle guidelines help:
- Keep it short. Around five minutes is enough. The goal is to clear your head, not to process your whole day.
- Stop before problem-solving. If you notice yourself planning solutions in detail, note the task and move on.
- Do it slightly before bed, in dim light, as part of a bedtime routine, rather than in bed under a bright lamp.
- Use paper rather than your phone, so you are not pulled into messages or bright screens.
For new parents: offloading the mental load
New parents often carry an enormous mental list: feeds, nappies, appointments, supplies, plus everything from life before the baby. When the house finally goes quiet, that list can start replaying, even when you are exhausted.
A short to-do list can be especially useful here. Writing down tomorrow’s tasks, however small, gives your mind permission to stop holding them. If you share care with a partner, a shared list on the fridge or in a notes app during the day can lighten the load further, so fewer things are left to replay at night.
Gratitude can feel harder to reach on very tired days, and that is fine. It does not need to be a big feeling. Noting one small thing that went okay, even “we got outside today”, can soften the end of a hard day.
If sleep is difficult even when the baby is sleeping, postpartum insomnia looks at why this happens and what helps.
For perimenopause: when worries arrive at 3 a.m.
Many women in perimenopause find that their mind becomes more active at night, particularly during early-morning wakings. A hot flash or night sweat may wake you, and then the thoughts start: tomorrow’s meeting, a family worry, something left undone.
Evening journaling can help by clearing some of those thoughts before bed. A notepad by the bed can help too. If you wake and a task or worry starts looping, writing it down in a few words, in dim light, gives it somewhere to go so you can let it rest until morning.
If you find yourself waking regularly in the early hours, why you wake at 3am explains what may be behind it, and waking up with anxiety looks at the anxious, wired feeling some women notice on waking.
Is it better to journal in the morning or at night?
Both have a place. For sleep specifically, a short evening session works well because it clears tomorrow’s tasks and gently settles the mind. Deeper reflective or emotional journaling, the kind where you work through something difficult, is often better earlier in the day, so you are not stirring up strong feelings right before you try to sleep.
If you enjoy both, a simple split can work: longer reflection in the morning or afternoon, and a five-minute list and a few lines of gratitude in the evening.
When journaling may not be enough
Journaling is a helpful, low-cost habit, but it is not a cure for every sleep problem. If you have had trouble falling or staying asleep most nights for several weeks, or if worry feels constant and heavy, it is worth talking to a doctor. Cognitive behavioural therapy for insomnia (CBT-I) is a well-established treatment, and our guide to treating insomnia without medication explains what it involves.
The calm version
Writing a specific to-do list and a few lines of gratitude before bed is one of the simplest ways to quiet a busy mind, and research suggests it can help you fall asleep faster. Keep it short, keep it gentle and keep it on paper. Mendtide’s morning briefing reads your Apple Health sleep data, so over a few weeks you can see whether evenings with a short wind-down tend to start more easily.
Your mind does not need to hold everything overnight. Put it on the page, and let the page keep it until morning.
