Give one task a clear start, a stopping point and a planned break.

**The number:** Use time blocks to limit task switching ([Oxford Health NHS Foundation Trust, 2025](https://oxfordhealth.nhs.uk/mindset/skills/time-optimisation/time-traps/))

## 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: 43/100. 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 skills guidance uses short work periods to cut down drifting between tasks. The Safren approach sizes each chunk to the attention span the person actually shows. No fixed Pomodoro schedule has an established ADHD treatment effect, and the programme evidence does not isolate timed blocks.

## How to do it

1. Pick one task and a small chunk of it.
2. Choose a work period short enough to try, and set a timer.
3. Park other tasks for later, and take a break when the block ends.
4. Size the next block by what happened, not by a fixed interval.

## Putting it into practice

### Start now

- 1 minute: Pick one task and a small piece you could do before a break.
- 5 minutes: Try a five minute start on that piece, with permission to stop afterwards.
- 15 minutes: Try one short focus period, a brief break and a check of what helped you stay with the task.
- 30 minutes: Run a work and break cycle that fits within half an hour, then adjust the next cycle.

### What it looks like

- Try a short block for an overdue form, then decide whether to continue.
- Use a longer block for engaging reading and a shorter one for dull admin.

### Common mistakes

- Treating a timer as a test can make starting harder, so shorten the block when needed.
- A break can become an unplanned detour, so decide how you will return before leaving the task.

### A structured start

**Find a workable rhythm**

1. Try a short block on one task.
2. Notice when attention drifts and adjust the duration.
3. Keep the rhythm only if it helps you start or return.
