Mentis- Thoughts get loud at night because nothing else competes for your attention, and tiredness makes problems look bigger.
- Hold a short "constructive worry" session in the early evening: worries on paper, one next step each.
- Write tomorrow's to-do list before bed. In one study it helped people fall asleep about 9 minutes faster.
- In bed, give your mind something gentle and dull to hold, and get up if you're still awake after about 20 minutes.
Why does my mind race at night?
During the day your attention is taken: the commute, the inbox, the family WhatsApp group, the next meeting. When you lie down in the dark, all of that stops at once, and the things you didn't have time to think about arrive together. Your body is tired, so your thinking is less flexible. A small worry about an email becomes a story about your career.
There's also a learning effect. If you've spent many nights thinking in bed, your brain starts to treat bed as the place for thinking. Sleep researcher Allison Harvey describes a cycle of worry, monitoring and alertness that keeps insomnia going: the more you worry about not sleeping, the harder sleep gets.
What helps before bed?
1. Hold a worry session at 7pm, not 1am
Pick 15 minutes in the early evening. Write down every worry, then beside each one write the smallest next step and when you'll take it. "Talk to my manager about the deadline: Monday 11am." If there's no step, write "nothing to do tonight". This is constructive worry. Carney and Waters tested it with college students who had insomnia, and it reduced pre-sleep mental arousal. Our worry timer sets it up for you.
2. Write tomorrow's to-do list
In Scullin's 2018 study, five minutes of writing a specific to-do list before bed helped people fall asleep about nine minutes faster. The more detailed the list, the bigger the effect. The open loops are off your mind and onto the page.
3. Make the last hour boring, on purpose
No work, no news, no heated chats, and no reels. Pick a small, repeatable wind-down: wash, change, dim the lights, read something gentle. The Sleep plan calls it "Pick Your Evening Switch And Set It Up". See phones before bed for why scrolling keeps your mind alert.

4. Give your mind a gentle job
An empty mind looks for something to chew on, so give it something harmless. Slow breathing with a long exhale is the best place to start: in for 4, out for 6 to 8, using our 4-7-8 timer if it helps. Or try cognitive shuffling: pick a word and picture random things for each letter. These tasks are absorbing enough to crowd out worry and dull enough to let sleep in.

5. Label it and let it pass
When a worry turns up, name it ("planning", "replaying", "what-if") and come back to your breath. You're not trying to solve it or stop it. You're declining to follow it. In the Mentis Overthinking plan this is part of the chapter Not now, built on worry-postponement research going back to Borkovec in 1983. McGowan and Behar's 2013 trial found that postponing worry to a set time reduced worry and anxiety.
6. Leave the bed if it isn't working
If you've been awake and thinking for what feels like 20 minutes, get up. Sit somewhere dim and write the thought down, or read something light, until you feel sleepy. Then go back. It teaches your brain that bed is for sleep, not for thinking.
What kinds of thoughts keep people awake?
- Replays: going over a conversation or mistake again and again. See replaying conversations.
- What-ifs: imagining everything that could go wrong tomorrow. See what-if thoughts.
- Planning: running through tasks. The to-do list helps most here.
- Sleep worry: "If I don't sleep now, tomorrow is ruined." See sleep anxiety.
- Self-criticism: a replay of everything you did wrong today. See the inner critic.
How Mentis helps
Mentis treats overthinking at night as a sleep problem and a thinking habit together. The Deep Sleep Reset plan has a whole chapter on The 3am mind, and the Overthinking plan builds the worry window step by step. Some nights you just need to get it out. Tap Rant, say or type everything, and Mimi will pull out the themes so they're waiting for you in the morning, not keeping you up now.

Frequently asked questions
Why do I overthink at night?
During the day, work, people and screens keep your attention busy. At night those distractions disappear, your body is tired, and unresolved worries rise to the surface. Fatigue also makes problems feel bigger and harder to solve.
How do I stop overthinking when trying to sleep?
Write your worries and one next step for each in the early evening, keep the last hour before bed calm, and in bed give your mind a gentle, boring task like slow breathing or cognitive shuffling. If you're still awake after about 20 minutes, get up until you feel sleepy.
Is overthinking at night a sign of anxiety?
It can be part of anxiety, but it's also a normal response to stress. If worry is hard to control on most days for months, and comes with restlessness, tension or poor sleep, take our anxiety self-check and consider speaking to a professional.
Does writing down thoughts before bed help?
Yes. In a 2018 study, people who wrote a specific to-do list for five minutes before bed fell asleep about nine minutes faster than people who wrote about completed tasks.
