Sleep and rotating shifts

4 min read

Sleep is the hardest part of shift work, because you're often trying to sleep when the world — and your body clock — expects you to be awake. Protecting your sleep is the single most useful thing you can do for your energy, mood and appetite.

Make your sleep space as dark, cool and quiet as possible: blackout curtains or an eye mask, earplugs or white noise, and your phone on silent. Treat daytime sleep as seriously as night-time sleep — ask people not to disturb you and keep a consistent wind-down routine, so your body learns the cue to sleep.

Light is a powerful signal. Bright light during your shift helps you stay alert; on the way home after a night shift, sunglasses cut the morning light that tells your brain to wake up, making it easier to fall asleep. In the evening before a night shift, brighter light can help you feel awake.

When shifts rotate, forward rotations (day → evening → night) are usually easier to adapt to than backward ones. Where you can, move your sleep gradually rather than all at once, and try to keep at least one anchor sleep period. Short naps of 20–30 minutes before or during a night shift can help, as long as they don't stop you sleeping later.

This is general wellbeing information, not medical advice. Ongoing insomnia, excessive sleepiness, or falling asleep when you shouldn't (such as while driving) are worth taking seriously — speak to your doctor or occupational-health service, because there is real support and treatment for shift-work sleep problems.
