If noticing the minutes pass is hard, put the time somewhere outside your head.

**The number:** Use timers and alarms as external time cues ([Leicestershire Partnership NHS Trust, 2026](https://www.leicspart.nhs.uk/while-you-wait/adhd/strategies-and-support/))

## The evidence

- How sure: Certainty of evidence: Not rated. Measured in people with ADHD.
- Evidence grade: C. Grade C: small or mixed studies, expert consensus or clinical practice. Worth knowing, not worth betting on.
- Basis: ADHD clinical guidance and programme content; the isolated strategy has no separately rated efficacy estimate.
- Benefit: 41/100. 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

ADHD research finds differences in time perception, though lab timing tasks do not prove that a visual timer helps in daily life. NHS guidance suggests clocks, timers and start or stop alarms. Treat them as practical prompts, with no promised size of benefit.

## How to do it

1. Pick one transition that often slips past you.
2. Put a clock or a countdown where you can see it.
3. Label the alarm with the action, like 'close laptop and get bag'.
4. Keep only the cues that get you to do something useful.

## Putting it into practice

### Start now

- 1 minute: Name a transition you often miss, and what you want its cue to make you do.
- 5 minutes: Set one clearly labelled transition alarm or place a clock in view.
- 15 minutes: Try your cue during one short task and check whether you noticed it.
- 30 minutes: Observe a routine with a visible clock and change only the cue that was easy to miss.

### What it looks like

- Use a visible countdown while getting ready to leave.
- Use an end alarm for a task that often runs into the next appointment.

### Common mistakes

- Too many alarms fade into background noise. Start with one important transition.
- A silent timer may go unnoticed. Pick a cue you'll actually notice.

### A structured start

**Test one time cue**

1. Choose one difficult transition.
2. Try a visible or audible cue.
3. Keep, move or remove it according to what happened.
