The laptop is closed and the lights are off, but the inbox is still open somewhere behind your eyes. A reply you could have worded better, tomorrow's meeting, a message that has not come back yet. If work follows you to bed, you have plenty of company.
Key takeaways
In the 2025 AASM Sleep Prioritization Survey of 2,007 U.S. adults, 65% said they had lost sleep over worries about work.
In a 2012 study of 719 workers, replaying worries with the feelings attached went with more fatigue, while thinking toward a plan went with less.
In a 2021 study of 220 people, racing thoughts at bedtime tracked insomnia severity in people with insomnia, while rumination and worry did not.
Small things to try tonight: Hypnagogia-Pass, a short list for tomorrow, and a closing cue for the workday.
Why work follows you to bed
In the 2025 AASM Sleep Prioritization Survey, an online poll of 2,007 U.S. adults run in June 2025 by Atomik Research for the American Academy of Sleep Medicine, 65% said they had lost sleep over worries about work. 78% said the same about money. A survey like this tells us how common the experience is. It does not tell us why it happens, and everyone answered for themselves.
One common explanation is simple. During the day, unfinished things keep getting pushed aside by the next task. At night nothing is competing for attention, so the mind goes back to whatever is still open.
Two kinds of thinking about work
A 2012 study by Querstret and Cropley in the Journal of Occupational Health Psychology surveyed 719 workers online and separated two ways of thinking about work after hours. Affective rumination is replaying worries with the feelings attached. Problem-solving pondering is thinking toward a plan. In that sample, affective rumination was the strongest predictor of work-related fatigue, while problem-solving pondering went with lower fatigue. Sleep quality sat partway between rumination and fatigue.
It was a one-time questionnaire, so it cannot show that either kind of thinking causes anything, and all of it was self-reported. It does suggest that circling and planning are different activities, even when both are about the same job.
Racing thoughts are not the same as rumination
In 2021, Luisa Weiner and colleagues published a study in Comprehensive Psychiatry with 220 participants: 72 adults with insomnia disorder, 49 patients in a hypomanic episode of bipolar disorder, and 99 healthy people. Everyone completed a questionnaire on racing and crowded thoughts. Racing thoughts were higher in the insomnia group, especially in people who struggle to fall asleep, and they rose in the evening and at bedtime.
The detail that stands out: in the people with insomnia, racing thoughts at bedtime were linked to how severe the insomnia was, while rumination and worry were not. The authors suggest racing thoughts may help keep sleep difficulties going beyond rumination and worry.
This was a questionnaire study in a clinical sample, so it shows an association, not a cause, and it was not about office workers. What it gives us is a useful distinction: a mind that replays one worry and a mind that fires off many thoughts at once may need different things. If the thoughts arrive fast and crowded, the first move is not to answer each one but to give the mind a slow, neutral thing to follow, which is what our cognitive shuffling for sleep guide and Hypnagogia-Pass are built around.
Three small things to try
Write down tomorrow's top three before you close the laptop. A short list gives unfinished things a place to wait.
Pick one small closing cue, such as shutting the tabs and saying "done for today" out loud, so the workday has an end you can notice.
If the loop starts in bed, keep the light low and give your attention something neutral instead of arguing with the thoughts. Our post on what to try when you can't sleep right now has more.
Your racing thoughts questions, answered
How to calm racing thoughts at night?
Hypnagogia-Pass gives the mind a slow sequence of unrelated words and pictures, with nothing to imagine and nothing to follow. Two other small options are a short list for tomorrow and a closing cue for the workday. Try one for a week and see what changes.
What causes your mind to race at night?
There is rarely one cause. In a 2021 study of 220 people, racing thoughts rose in the evening in people who find it hard to fall asleep, and they were separate from rumination and worry. Unfinished tasks may also come back once nothing else competes for attention.
Is rumination the same as racing thoughts?
No. Rumination is replaying a worry with the feelings attached, while racing thoughts are fast and crowded. In the same 2021 study, racing thoughts at bedtime tracked insomnia severity and rumination did not. They can show up together, and an argument that keeps replaying is a common example of rumination.
How do you stop thinking about work at night?
Close the loop before bed: write tomorrow's top three, pick a small closing cue such as shutting the tabs, and aim your night thinking at a plan rather than a replay. In a 2012 study of 719 workers, problem-solving pondering went with lower fatigue and affective rumination with higher.
How common is losing sleep over work worries?
In the 2025 AASM Sleep Prioritization Survey of 2,007 U.S. adults, 65% said they had lost sleep over worries about work and 78% over money. It is an online poll, so it shows how common the experience is, not why it happens. The clock change can add to it: see sleep after daylight saving ends.
Are racing thoughts at night a sign of ADHD or anxiety?
They can go along with anxiety, ADHD, insomnia and other conditions, but racing thoughts alone do not show which one, if any, applies. Stress, caffeine and a busy evening are also common causes, and only a clinician can tell these apart for you.
Why does anxiety feel worse at night?
Daytime distractions fade at night, so worries can sound louder, and trying hard to fall asleep can raise alertness even more. Tiredness also makes problems feel bigger. Giving your attention something gentle to follow may ease the loop for some people.
Something to try tonight
Hypnagogia-Pass is our library of 30 videos, more than 2,400 minutes in total, curated by CantSwitchOff to walk you through the hypnagogic pass: a word, then a matching picture, one after another on a dark screen, with no talking and soft background sound. Every word and picture is chosen to be unrelated to the one before it, so the mind has nothing to link two in a row and can keep drifting instead of building a story about the workday. It was inspired by Luc Beaudoin's serial diverse imagining. You can read why we built it or our post on cognitive shuffling for sleep, or try it at members.cantswitchoff.com.

If trouble sleeping lasts for weeks, or if racing thoughts come with other symptoms that worry you, please talk with a doctor. This article is general information, not medical advice, and Hypnagogia-Pass has not been tested in a clinical trial.
