Anyone who has worked through the night knows the odd feeling of driving home while the rest of the world is starting its day. The roads are busy, the sun is up, and your body is telling you two different things at once: you are exhausted, yet you feel strangely wired. Then you get into bed and stare at the ceiling for an hour.
Daytime sleep is one of the hardest parts of shift work, and it is not a matter of willpower. Your body clock is built to keep you awake when it is light and wind you down when it is dark. Working nights asks you to flip that rhythm, so the trick is to give your body as many “it’s night now” signals as possible, even at 9am. Here is what helps.
- Protect the journey home
Morning daylight is one of the strongest signals telling your brain to wake up. If you can, wear sunglasses on the way home, even on a cloudy day. Avoid stopping at bright supermarkets or scrolling your phone in the car park. The aim is to keep your brain in wind-down mode until your head hits the pillow.
- Make your bedroom properly dark
Ordinary curtains are not enough for daytime sleep. Blackout blinds, blackout curtain linings or even temporary blackout film on the windows make a real difference. A comfortable eye mask is a cheap backup. Cover or turn away any glowing standby lights on chargers and TVs. If you can read a book in your bedroom without a lamp, it is still too bright.
- Block out daytime noise
The daytime world is loud: bin lorries, deliveries, neighbours, school runs. Foam earplugs, a fan or a white noise app can mask a lot of it. Let the people you live with know your sleep hours, put your phone on do not disturb, and consider a simple sign on the front door asking couriers not to knock.
- Keep the room cool
Your body temperature naturally drops as you fall asleep, and a warm room in the middle of the day works against that. Aim for a cool, well-ventilated bedroom, use lighter bedding in summer and take a lukewarm shower before bed rather than a hot one.
- Time your caffeine carefully
Coffee is a lifeline on a long night, but caffeine can stay in your system for many hours. A good rule is to stop caffeine roughly six hours before you plan to sleep. If you finish at 7am and want to be asleep by 8am, that means your last coffee should be around 2am. Swap later cups for water or decaf.
- Eat light before bed
A heavy meal right before sleep can leave you uncomfortable and restless. If you are hungry after your shift, go for something small and easy to digest, like toast, yoghurt, a banana or a bowl of porridge. Try to have your main meal earlier in the shift rather than at the very end of it.
- Build a short wind-down routine
Day workers have the evening to unwind. Night workers often go straight from a busy floor to bed, and the mind is still racing. A short routine of 15 to 20 minutes helps signal that the day is over: a shower, changing into comfortable clothes, a few pages of a book, some gentle stretching or slow breathing. Keep it the same every time so your body learns the pattern.
- Stick to a consistent sleep window
As much as rotas allow, try to sleep at the same time after each night shift. Some people do best sleeping straight after work, for example 8am to 3pm. Others prefer a split approach, with a shorter sleep in the morning and a nap before the next shift. Experiment for a couple of weeks and stick with what leaves you feeling most rested.
- Plan your days off
Switching back to a daytime routine on your days off is tough. A common approach is a short “anchor” sleep after your last night shift, followed by getting outside in daylight in the afternoon and going to bed at a reasonable hour that evening. Avoid sleeping all day and then lying awake all night.
- Look after the basics
Shift work makes it easy to let nutrition slide. Vending machine snacks, skipped meals and long gaps between eating are common on nights. A balanced diet with plenty of vegetables, wholegrains, nuts, seeds and leafy greens gives your body the vitamins and minerals it needs. Magnesium is one mineral worth paying attention to, as it contributes to the normal functioning of the nervous system, normal muscle function and the reduction of tiredness and fatigue. Good food sources include spinach, almonds, pumpkin seeds and beans. Some shift workers also choose a supplement such as magnesium glycinate capsules, a form many people find gentle on the stomach. As with any supplement, check the label, stick to the recommended dose and speak to a pharmacist or GP if you take other medication.
When to get help
Feeling tired after nights is normal. Feeling exhausted all the time, nodding off while driving, or struggling to sleep even when you have every condition right is not something to push through. Shift work sleep problems are common and well recognised, so it is worth talking to your GP or occupational health team if things are not improving.
The bottom line
You cannot completely fool your body clock, but you can make daytime sleep much easier. Darkness, quiet, a cool room, sensible caffeine timing and a steady routine do most of the heavy lifting. Small changes, repeated consistently, add up to better rest and better nights at work.
