Journaling Before Bed: How Writing Helps You Sleep
If your mind races the moment your head hits the pillow, a few minutes of journaling can help. Here's the research on writing for sleep — including the study that found a to-do list beats counting sheep.
You’re exhausted, you lie down, and suddenly your brain decides it’s time to review every open worry and tomorrow’s to-do list. This nighttime mental racing is one of the most common causes of trouble falling asleep — and it’s exactly what a few minutes of journaling before bed can quiet. Here’s the research and a simple wind-down routine.
The study: a to-do list beats counting sheep
In a clever 2018 experiment published in the Journal of Experimental Psychology: General, Scullin and colleagues had people either write a brief to-do list of upcoming tasks or write about tasks they’d completed before bed. The to-do-list group fell asleep significantly faster.
Why? Unfinished tasks nag at the mind, keeping it activated. Writing them down appears to “offload” them — your brain can stop rehearsing them because they’re safely captured on paper. It’s the same cognitive-offloading principle behind journaling for stress.
Gratitude helps too
Separately, research has linked gratitude to better sleep. Wood and colleagues (2009) found that more grateful people tended to report better sleep quality — in part because they had more positive and fewer anxious thoughts at bedtime. A short gratitude note (see gratitude journaling) can shift the mental channel away from worry as you drift off.
A 5-minute bedtime wind-down
Keep it brief and low-key — writing shouldn’t become stimulating:
- Brain dump (2 min). Everything still spinning — worries, reminders. Get it out of your head and onto the page.
- Tomorrow’s list (1 min). The few things you don’t want to forget. Now your brain can stop guarding them.
- One good thing (1 min). A small moment you’re grateful for from today.
- Lights out. No re-reading, no editing. You’ve handed the day to the page.
What to avoid
- Don’t problem-solve in bed. Capture the worry; don’t try to fix it at midnight. “I’ll handle this tomorrow” plus a written note is enough.
- Keep screens dim if journaling in an app — or use night settings.
- Don’t make it a chore. Two honest minutes beats a pressured page.

Make it effortless at bedtime
The last thing a tired brain wants is a blank page. Wisp opens to a gentle prompt, keeps everything private, and takes two minutes — so the wind-down is realistic even when you’re half-asleep. Offload the day, note one good thing, and let your mind rest.
Persistent insomnia deserves professional attention — journaling is a helpful wind-down, not a treatment for a sleep disorder.
Tonight, before you close your eyes: dump the worries, list tomorrow’s few must-dos, and name one good thing. Then let go.
Frequently asked questions
- Does journaling before bed help you sleep?
- Research suggests it can. A 2018 study by Scullin and colleagues found people who wrote a short to-do list before bed fell asleep faster than those who wrote about completed tasks — offloading tomorrow's worries appears to quiet a racing mind. Gratitude journaling has also been linked to better sleep quality.
- What should I write before bed to sleep better?
- Two things work well: a brief to-do list or 'brain dump' to get open loops out of your head, and a short gratitude note to settle your mood. Keep it brief and low-stakes so writing itself doesn't become stimulating.
- Is it better to journal before bed or in the morning?
- For sleep specifically, evening wins — it clears the mental clutter that keeps you awake. For focus and intention, morning is better. Many people do a quick version of both. See our morning vs. evening guide for the full comparison.
