The 3 AM Problem
You know the feeling. It's late, you're tired, and the moment your head hits the pillow, your brain decides it's time to review every conversation from the past week, plan the next five years, and remember that embarrassing thing you said in 2019.
This is cognitive arousal — your mind is too active to allow sleep. If this sounds like anxiety, you're right — it's closely related. And it's one of the most common causes of insomnia, affecting roughly a third of adults at any given time.
Journaling before bed directly addresses this problem. Not by solving your concerns, but by giving them somewhere to go that isn't your pillow. Our evening journaling routine covers a complete 15-minute practice that includes sleep preparation.

What the Research Says
A study published in the Journal of Experimental Psychology found that participants who spent five minutes before bed writing a to-do list for the next day fell asleep significantly faster than those who wrote about completed tasks. The act of offloading future concerns onto paper freed the brain from holding onto them.
Other research has shown that expressive writing — writing about thoughts and feelings — reduces the physiological stress response. Lower cortisol levels at bedtime mean your body can actually shift into sleep mode.
The connection is straightforward: a quieter mind falls asleep faster.
Technique 1: The Worry Offload
This is the simplest and often most effective technique.
How to Do It
Five minutes before your target bedtime, write down everything that's occupying your mind. No structure, no judgment — just transfer it from brain to page.
Include:
- Tasks you didn't finish today
- Things you need to remember tomorrow
- Worries, even irrational ones
- Unresolved conversations or decisions
Why It Works
Your brain treats unfinished tasks like open browser tabs — they keep running in the background. Writing them down is like closing the tab. The task isn't forgotten; it's saved. Your brain can let go because it trusts the external record.
Technique 2: The Completion List
The opposite approach — writing about what you accomplished today.
How to Do It
List five to ten things you completed today. Include small things:
- Sent that email I'd been putting off
- Had a good conversation with my partner
- Cooked dinner instead of ordering
- Made it through a tough meeting
- Went for a walk during lunch
Why It Works
Anxiety about productivity often keeps people awake. You lie in bed thinking about what you didn't do, which triggers stress. A completion list counters this by giving your brain evidence that you were, in fact, productive. It creates a sense of closure for the day.
Technique 3: The Thought Release
More emotional than the first two techniques — this one works for nights when your mind is heavy, not just busy.
How to Do It
Write a stream of consciousness for five to seven minutes. Whatever comes to mind — frustrations, sadness, excitement, confusion. Don't try to make it make sense. Don't censor yourself.
End with a closing statement: "I'm releasing these thoughts for the night. They'll be here tomorrow if I need them."
Why It Works
Emotional suppression — trying not to think about something — actually increases intrusive thoughts (the "white bear" problem). Writing is the opposite of suppression. You're acknowledging the feelings, giving them space, and then deliberately setting them aside.
Technique 4: The Gratitude Wind-Down
A gentler approach for people who find worry-focused journaling too activating before bed.
How to Do It
Write three things you're grateful for from today. Be specific:
- "The warm sunlight coming through my window during lunch"
- "My colleague laughing at my joke during the standup"
- "The quiet ten minutes I had with my morning coffee"
Then write one thing you're looking forward to tomorrow — even something simple like a meal you'll enjoy or a podcast episode you want to listen to.
Why It Works
Gratitude journaling before bed shifts your cognitive focus from threats to rewards. Instead of lying in bed scanning for problems (which is anxiety's default setting), your brain's last active thoughts are positive ones. Research shows this leads to more positive pre-sleep thoughts, which correlates with faster sleep onset.
The 5-Minute Sleep Journal Routine
Combine the best elements into one short routine:
- Offload (2 min) — Write tomorrow's top three priorities
- Complete (1 min) — Note one thing you did well today
- Release (1 min) — Write down the one thought that's loudest right now
- Gratitude (1 min) — One specific thing you're grateful for
Five minutes total. Do it at a desk or table, not in bed. Then close the journal, brush your teeth, and go to sleep.
What to Avoid
Don't Journal on Your Phone in Bed
The blue light from screens suppresses melatonin production, making it harder to fall asleep. If you use a digital journal, write your entry before you get into bed, then put the phone away.
Many phones have a "night mode" that reduces blue light — use it if evening journaling is your preference.
Don't Problem-Solve
Bedtime journaling is for offloading, not for figuring things out. If you find yourself developing action plans and getting mentally activated, you've gone too far. Save the problem-solving for morning.
Don't Write for Too Long
More than 10 minutes of pre-sleep writing can actually increase arousal as you dig deeper into topics. Keep it brief. The goal is to drain the mental buffer, not to explore every thought.
Don't Reread Old Entries Before Bed
Save journal reviews for daytime. Reading about past worries or emotional experiences can reactivate those feelings, which is counterproductive at bedtime.
Building the Sleep Journaling Habit
Pair It with Your Existing Routine
Insert journaling into your existing bedtime sequence:
- Evening routine → brush teeth → journal for 5 minutes → lights out
Keep Your Journal Bedside
Whether it's a notebook on your nightstand or your phone with the journal app on the home screen, remove any friction between "I should journal" and actually doing it. For more on reducing friction, see our guide to building a writing habit.
Track the Results
After a week of bedtime journaling, note:
- How long it takes you to fall asleep (rough estimate)
- How many times you wake during the night
- How rested you feel in the morning
With Muse Journal's mood tracking, you can log your sleep quality alongside your evening entry — building a clear picture of how journaling impacts your rest.
When Journaling Isn't Enough
If you consistently can't sleep despite good sleep hygiene and bedtime journaling:
- Consider whether caffeine, alcohol, or screen time are factors
- Talk to your doctor — chronic insomnia may have medical causes
- Cognitive Behavioral Therapy for Insomnia (CBT-I) is highly effective and often available online
Journaling is one piece of the sleep puzzle. It works best as part of a broader approach to winding down.

Try It Tonight
Tonight, before bed, spend five minutes writing down what's on your mind. Don't overthink it. Just get the thoughts out of your head and onto paper.
Pay attention to what happens when you close your eyes. For many people, the difference is immediate — the racing thoughts have somewhere else to live, and the mind finally has permission to rest.
