Planning sleep around shifts helps preserve the time your body needs to recover.

**The number:** Increase sleep opportunity and limit shift changes when possible ([NHLBI, NIH, 2022](https://www.nhlbi.nih.gov/health/sleep-deprivation/healthy-sleep-habits))

## The evidence

- Evidence grade: B. Grade B: consistent large cohort studies, with some trial evidence.
- Basis: NIH and NIOSH shift work guidance; NHS identifies shift work as an insomnia trigger
- Impact: 38/100. The impact score is an editorial prioritization heuristic for the general list, not a validated estimate of your personal risk.

## Why it matters

Shift work can put working hours in conflict with the internal body clock. NIH advises increasing sleep opportunity, while NIOSH emphasizes recovery time when designing shifts. No single schedule suits everyone or eliminates the health risks of shift work.

## How to do it

1. If you work shifts, reserve a main sleep period in your schedule.
2. Use a nap when needed to increase your total sleep opportunity.
3. Discuss a schedule that protects recovery with your employer; permanent night shifts are not best for everyone.

## Talk to a clinician first

Seek clinical help if you cannot sleep adequately or remain excessively sleepy despite protecting time for sleep.

## Putting it into practice

### Start now

- 1 minute: Identify your next main sleep period around your shift and one optional task you can move to protect it.
- 5 minutes: Check your next shift and travel times, then reserve a main sleep window; note any household noise or light you can reduce.
- 15 minutes: Plan sleep opportunities around your next few shifts, including a nap if helpful, and prepare your room for the times you will actually sleep.
- 30 minutes: Review a full roster for gaps in recovery time, write down the changes that would help and prepare a discussion with your employer or occupational health service.

### What it looks like

- Protect a main daytime sleep period after a night shift and let people at home know when it is.
- Use light-blocking curtains for daytime sleep if light keeps you awake.
- If you use caffeine during a shift, keep it to the first part rather than near your sleep period.

### Common mistakes

- Treating poor sleep as only a bedroom problem can miss an exhausting roster, so discuss recovery time with your employer.
- Using one fixed sleep schedule for every roster can be unrealistic, so plan around your actual shifts and seek help if you remain sleepy.

### A structured start

**Protect recovery around your roster**

1. Stage 1: Map work, travel and necessary commitments against available sleep time.
2. Stage 2: Protect a main sleep opportunity and arrange a quieter, darker room for daytime sleep.
3. Stage 3: Consider additional sleep opportunities such as naps and discuss insufficient recovery time at work.
4. Stage 4: Seek clinical help if adequate sleep remains difficult or excessive sleepiness continues.
