How to Sleep When You Work Night Shifts: A Practical Guide

I've worked night shifts in a warehouse for the past 12 years. Rotating shifts — four on, four off, sometimes six on, two off. And in that time, I've pretty much tried everything the internet tells you to do about shift work sleep. Most of it works, if you actually do it. The problem is that most advice assumes you have complete control over your life, and when you're working nights, you don't.

So this isn't the polished version. This is what actually works when you're knackered, your neighbours are mowing the lawn, and your body clock thinks it's dinner time at 3am. Here's what works for sleeping during the day — and how to do it.

The Unique Problem of Shift Work Sleep

First, Honestly, about what's going on. Your body isn't broken — it's doing exactly what it was designed to do. Your circadian rhythm is wired to keep you awake during daylight and asleep when it's dark. When you work nights, you're fighting millions of years of evolution. That's not something you overcome with willpower alone. You have to work with your biology, not against it.

The main challenges shift workers face come down to three things:

• Light at the wrong time — your body treats sunlight as a "wake up" signal, even when you've just finished a 10-hour night shift
• Social pressure — your mates don't understand why you can't go out on a Friday night when you've got a shift Saturday morning
• Inconsistency — rotating shifts mean your body never fully adjusts, because by the time it does, your schedule changes again

Understanding these three issues is the foundation. Everything else builds on top of them.

Light Exposure: Your Biggest Lever

Light is the single most powerful tool you have as a shift worker. It sounds simple, but managing it properly changed everything for me.

When you finish a night shift, it's morning. The sun is up. Your body is flooded with cortisol and ready to start the day. But you need to sleep. This is where most people go wrong — they walk out of work into bright sunlight, and their brain says "right, new day, let's go." Two hours later they're still staring at the ceiling.

Here's what I do:

• Wear sunglasses on the drive home — proper wraparound ones, not your Ray-Bans. I keep a cheap pair in the car specifically for this. It sounds over the top, but it cuts the light signal to your brain dramatically.
• Get blackout curtains or blinds — and I mean proper ones. The cheap ones from B&M won't cut it. Proper blackout blinds — around £40 for a bedroom — are consistently rated by shift workers as one of the best investments they've made for sleep. Every tiny bit of light leaking around the edges matters when your body is screaming at it to wake up.
• Wear an eye mask for backup — even with blackout blinds, some light sneaks through. A decent contoured eye mask seals the deal. I use one that doesn't press on my eyelids so I can actually blink comfortably.
• Get bright light at the right time — and this is the other side of the coin. When you wake up (say, 2pm), get some light. Step outside, open the curtains. Light exposure after waking helps reset your clock and keeps your energy up for the evening shift ahead.

Creating a Daytime Sleep Sanctuary

Your bedroom needs to become a bunker. I'm not exaggerating. When you're sleeping at 9am on a Tuesday, the world outside is doing everything it can to keep you awake. Delivery drivers, bins being collected, children, traffic, postmen — you name it.

Here's what's worked for me, in order of importance:

• Blackout blinds — I've already mentioned these, but they're that important. I repeat it on purpose.
• White noise machine or app — I use a simple fan, which does double duty: masks noise and keeps the room cool. If a fan isn't enough, a white noise app on your phone (set to "brown noise" — it's less irritating than white) or a dedicated white noise machine works well. The consistent background sound masks sudden noises that jolt you awake.
• Tell people you're sleeping — This is the hardest one. Tell your partner, your kids, your housemates. Put a sign on the door. Some people feel embarrassed about it, but honestly, nobody cares as much as you think they do. A simple "I'm on nights, please keep it down" goes a long way.
• Keep the room cool — Daytime sleeping means warmer temperatures. Use lighter bedding in summer and keep the room between 16–18°C if possible. If you haven't got air conditioning (and Honestly, most UK houses don't), a fan pointed at you works wonders. Check out our full guide on room temperature for sleep for more detail.
• Put your phone on Do Not Disturb — set exceptions for your partner or kids if needed, but block everything else. That Amazon delivery notification can wait.

Food Timing: What You Eat Matters as Much as When

This one took me years to get right. When you're working nights, your eating pattern gets completely mucked up. Vending machine meals, kebabs at 2am, energy drinks to keep going — it all feels necessary in the moment, but it destroys your ability to sleep properly.

Here's the approach that works for me:

• Eat your last big meal 3–4 hours before you plan to sleep — not one hour before, not "just a quick snack." Your body needs time to digest. A full stomach raises your core temperature and keeps your digestive system active, both of which fight sleep.
• Front-load your calories — eat more during the first half of your shift when you're active and alert. Save the lighter stuff for the second half. I bring a packed lunch and snacks rather than relying on what's available at work.
• Avoid heavy, greasy food on shift — I know the chippy is tempting at 1am, but greasy food gives you an energy spike followed by a crash, and the heaviness sits in your stomach when you're trying to wind down.
• Watch the caffeine — I cut caffeine at least 5 hours before my planned sleep time. If I finish at 7am and want to sleep by 9am, that means no coffee after about 4am. This was brutal at first, but it made a real difference to how quickly I fall asleep. For more on this, our article on Why Am I Tired All The Time covers how caffeine disrupts sleep quality even when you think you're fine.
• Stay hydrated — dehydration causes fatigue, which makes you more reliant on caffeine, which makes sleep harder. It's a vicious cycle. Keep water with you on shift.
