Working nights, early starts or rotating rosters can throw your body clock out of step with the world around you. Poor shift work sleep is very common, but small, consistent habits can make a real difference. This guide from Guardian Pharmacy shares practical ways to protect your rest and your health.
Key takeaways
- Your body clock responds strongly to light, so managing light exposure matters.
- A protected, dark and quiet sleep space helps you sleep in the daytime.
- Planning meals, caffeine and short naps around your shifts can ease tiredness.
- Speak to your GP or pharmacist if sleep problems or sleepiness continue.
Why shift work affects your sleep
Your body runs on an internal clock that follows a roughly 24-hour cycle. It is guided mainly by daylight and darkness. Working at night asks you to be alert when your body expects to sleep, and to sleep when it expects to be awake.
This mismatch can lead to shorter, lighter sleep, tiredness at work and trouble switching off on days off. Many shift workers also find it affects mood, appetite and digestion.
Manage light to support shift work sleep
Light is the strongest signal for your body clock, so using it wisely is one of the best ways to improve shift work sleep.
- Keep your workspace well lit during night shifts to help you stay alert.
- Wear sunglasses on the journey home after a night shift to limit morning light.
- Make your bedroom as dark as possible with blackout curtains or an eye mask.
- Dim lights and avoid bright screens in the hour before you plan to sleep.
Create a daytime sleep routine
Daytime sleep is lighter and easier to interrupt, so protect it. Try to keep the same sleep schedule on consecutive work days, and wind down with the same calm routine each time.
Silence your phone, ask people at home not to disturb you, and use earplugs or a white noise source if outside sounds wake you. Keep the room cool and comfortable. Many of the basics in our guide to sleep hygiene tips to help you fall asleep faster apply just as well after a night shift.
If you can, avoid driving home when very drowsy. Ask whether a lift, public transport or a short rest before the journey is possible.
Food, caffeine and naps
What and when you eat can influence how you feel. Aim for regular, lighter meals and healthy snacks during the night rather than large, heavy meals, which can leave you sluggish and unsettled.
Caffeine can help you stay alert early in a shift, but it lingers in the body. Try to stop several hours before you plan to sleep. A short nap before a night shift, if your schedule allows, may also help you feel more alert.
Alcohol may make you feel sleepy but tends to disturb sleep, so it is not a reliable way to wind down. Staying active and drinking plenty of water also help your energy levels.
Looking after yourself long term
Long-term sleep disruption can add up. If trouble sleeping continues even on days off, it may be more than a shift pattern issue. Our guide to insomnia causes and when to see your GP can help you decide what to do next.
Constant tiredness can have other explanations as well, covered in why you might always feel tired. If you are struggling with your mood, Mind has helpful information, and the NHS website offers general advice on sleep. Let your employer or occupational health team know if your rota is affecting your health, as adjustments are sometimes possible.
When to speak to a professional
See your GP if you are sleepy at work or while driving, if poor sleep lasts for weeks, or if you notice low mood, heart or stomach problems you are worried about. A pharmacist can talk through safe ways to manage tiredness and check any medicines you take. Call NHS 111 if you are unsure what to do. If you feel you cannot cope or have thoughts of harming yourself, contact Samaritans free on 116 123, or call 999 in an emergency.
Frequently asked questions
Can my body clock ever fully adjust to night shifts?
Most people find it hard to adjust completely, especially if they return to daytime routines on days off. Consistent light and sleep habits can still make things easier.
Should I sleep straight after a night shift?
Many people do best going to bed soon after getting home, in a dark room. Others prefer a short sleep then a longer one later. Try what suits you and keep it consistent.
Are energy drinks a good way to stay awake?
They can provide a short-term lift but may disturb later sleep and are not a substitute for rest. Water, light meals and movement are gentler options.
Can a pharmacist help with tiredness from shift work?
Yes. A pharmacist can offer general advice, check whether your medicines may affect alertness and tell you when to see your GP.
