Give sleep a predictable place in your day, and get help if the timing stays hard.

**The number:** Wake up at the same time each day ([NHS, 2024](https://www.nhs.uk/conditions/insomnia/))

## The evidence

- How sure: Certainty of evidence: Not rated. Measured in the general population; we say so because ADHD trials of this do not exist or are too small.
- Evidence grade: B. Grade B: trials in ADHD with low certainty, or strong general health evidence with a sourced reason it matters more with ADHD.
- Basis: NHS general sleep guidance, NHS adult ADHD self-care advice and a meta-analysis of sleep in adults with ADHD; no formal certainty rating for this habit.
- Benefit: 67/100. The benefit score is an editorial prioritization for the general list, weighted by certainty. It is not a prediction of what will happen for you.

## Why it matters

General sleep guidance backs regular sleep and wake times over repeatedly cutting sleep short. The NHS page on adult ADHD says a regular bedtime can help. Adults with ADHD report more sleep difficulties than adults without ADHD, though objective sleep findings are less consistent. A steady schedule can support sleep, but it is not a proven treatment for core ADHD symptoms or a cure for a delayed body clock.

## How to do it

1. Pick a wake time you can usually keep that still leaves enough time for sleep.
2. Keep the bedroom quiet and dark, and go to bed when you're sleepy.
3. If falling asleep or waking stays hard, take your sleep pattern to a clinician.

## Talk to a clinician first

If sleep problems persist or affect daily life, get assessed. Medication changes belong with your prescriber.

## Putting it into practice

### Start now

- 1 minute: Pick a wake time that works most days of your week without cutting your sleep short.
- 5 minutes: Compare your workday and free-day sleep times and identify the biggest mismatch.
- 15 minutes: Write a brief account of when you feel sleepy, fall asleep and wake, including the effect on your day.

### What it looks like

- Use a similar wake time on workdays and free days.
- If you lie awake despite allowing enough sleep time, tell your clinician what happens.

### Common mistakes

- Going to bed earlier may not make you sleepy. Get advice if your body clock keeps running late.
- A bad night is no reason to cut sleep further. Go back to a sleep window that works.

### A structured start

**Make sleep timing workable**

1. Choose a realistic sleep window.
2. Try keeping the timing similar across the week.
3. Bring persistent difficulty to a clinician.
