Nurses, warehouse staff, drivers, security guards, care workers, bakers, factory crews. A big part of the world keeps running while everyone else sleeps. Working nights goes against the body's natural clock, and there's no trick that makes that cost disappear completely. But there's a lot you can do to make it smaller. Here's what works for many night workers.
Sleep: protect it like it's part of the job
Day sleep is harder than night sleep. It's lighter, it gets interrupted more, and the world is noisy. So your environment has to do more of the work.
- Make the bedroom properly dark. Blackout curtains or blinds, plus tape over standby lights. An eye mask is a cheap backup.
- Block the noise. Earplugs, a fan or a white-noise app help with traffic, deliveries and neighbours.
- Keep it cool. A cooler room helps with sleep, and summer afternoons are a challenge.
- Tell the people around you. Agree "do not disturb" hours with the people you live with, and put a note on the door for deliveries.
- Silence your phone. Use a Do Not Disturb schedule, with exceptions for genuine emergencies.
Try an "anchor sleep"
Many shift workers find it helps to keep a core block of sleep, for example four hours, at the same time every day, including days off. Extra sleep can then go before or after it. The anchor gives your body clock something stable to hold on to.
Use naps strategically
- Before your first night shift, a longer nap in the afternoon (around 90 minutes) can make the first night easier.
- During a break, if your workplace allows it, a short nap of 10–20 minutes can boost alertness without leaving you groggy.
Light: your most powerful tool
Light is the main signal your body clock uses to know what time it is. You can use that.
- Bright light during the first half of your shift helps you feel more alert.
- Less light on the way home. Morning sunlight tells your body "it's daytime, wake up!", which is the opposite of what you need. Many night workers wear sunglasses on the journey home.
- Go straight to bed if you can, rather than starting chores or scrolling in a bright room.
Caffeine: timing is everything
Caffeine works, but it lasts. On average it takes around five hours for your body to get rid of half of it, and much longer for some people. Use it early in your shift, and stop several hours (around six is a sensible rule of thumb) before you plan to sleep. A coffee at 5 a.m. may still be keeping you awake at 10.
Food: lighter at night
- Your digestion is also on a body clock, and it doesn't love big meals in the middle of the night. Many people feel better eating their main meal before the shift and having lighter snacks during it.
- Choose protein, fruit, vegetables, nuts and wholegrains over sugary snacks, which lead to an energy crash.
- Drink water through the shift. Mild dehydration can feel a lot like tiredness.
The drive home
The most dangerous part of a night shift is often the trip home. Drowsy driving is genuinely risky. Warning signs include yawning, heavy eyelids, drifting out of your lane or not remembering the last few kilometres. If you feel them, pull over somewhere safe and take a short nap. Opening the window and turning the music up doesn't fix it. If you can, use public transport, share a ride, or have a short nap before you leave work.
A social life on the wrong hours
One of the hardest parts of night work is feeling out of sync with friends and family. A few things help:
- Schedule people like appointments. A standing breakfast after your last shift, or a weekly call on your day off.
- Share your rota so the people who care about you know when you're free.
- Find people on the same hours. Other shift workers get it in a way day workers often don't. That's a big part of why LatePals exists: a place where someone is still around at 3 a.m.
Look after your health
Long-term night work is linked with a higher risk of some health problems, so the basics matter more: regular exercise, check-ups with your doctor, and taking sleep problems seriously. If you're constantly exhausted, can't sleep even when you have the chance, or fall asleep when you don't mean to, talk to a doctor. Some people develop what's called shift work disorder, and there are treatments that help.
