Why is sleep different for shift workers?
Your body has an internal 24-hour body clock (circadian rhythm) that naturally promotes wakefulness during the day and sleep at night. Working evenings, nights or rotating shifts can disrupt this rhythm, making it harder to:
- Fall asleep
- Stay asleep
- Feel alert at work
- Recover between shifts
The goal isn't perfect sleep, it's getting the best quality sleep possible when you have the opportunity.
How to Maximise Sleep during Shift Work
1. Plan your sleep like part of your shift
Sleep is not “free time”, it is recovery time.
Try this
Block sleep time in your calendar.
- Let family or housemates know when you need quiet
- Aim for 7–9 hours of sleep across 24 hours where possible
- Use short naps to top up sleep before a night shift
Protecting sleep helps protect your health and safety.
2. Control light on the way home
Light tells your body it is time to be awake. After a night shift, bright morning light can make it harder to fall asleep.
Try this
- Wear sunglasses on your way home
- Avoid running errands straight after night shift
- Keep lights low when you get home
- Go to bed as soon as practical
Less light after night shift helps your body prepare for sleep.
3. Make daytime sleep feel like night-time sleep
Sleeping during the day is harder because the world is awake.
Try this
- Use blackout curtains or an eye mask
- Wear earplugs or use white noise
- Keep your room cool and quiet
- Put your phone on Do Not Disturb
Dark, quiet and cool is the goal.
4. Use caffeine strategically
Caffeine can help with alertness, but timing matters.
Try this
- Use caffeine early in your shift if needed
- Avoid caffeine in the final 4–6 hours before sleep
- Switch to water later in the shift
- Be mindful of energy drinks, coca cola and strong tea too
Caffeine should support your shift, not steal your sleep.
5. Nap before night shift
A short nap before work can reduce sleepiness later in the shift.
Try this
- Take a 20–30 minute nap before starting night shift
- Keep it short to avoid waking groggy
- Allow time to fully wake up before driving or operating equipment
Think of it as a fatigue buffer.
6. Be careful driving home
The commute after a night shift can be one of the riskiest parts of the day.
Try this
- Avoid driving if you feel very sleepy
- Carpool or use public transport where possible
- Pull over safely if you notice warning signs
- Do not rely on loud music or open windows to stay awake
If you are struggling to stay alert, it is not safe to keep driving.
