Sleeping, Eating and Exercise Tips For People Who Work Shifts

Nurses, paramedics, factory workers, airline crews, hospitality staff and casino dealers keep the world running around the clock. Shift work also makes it harder to sleep, eat well and exercise, and long-term night work is linked with higher risks of weight gain, type 2 diabetes and heart disease. The good news: some practical habits make a real difference.

First, identify the real problem

Before fixing everything at once, find the root cause. Write down what is bothering you, for example "I've gained weight since starting shifts", and list the reasons: no time for the gym, vending machine snacks at 3am, always tired, oversleeping on days off. Then ask "why?" for each one. Very often the answers lead back to a single cause, such as not enough sleep. Fix that first; trying to change everything at once drains willpower.

Sleeping tips

1. Keep your sleep length consistent. If you rotate shifts, you cannot always sleep at the same time, but you can aim for a similar amount of sleep each day, ideally 7 hours or more.
2. Use naps strategically. A short nap of 20 to 30 minutes before a night shift, or a longer one of around 90 minutes (roughly one full sleep cycle), can improve alertness. Avoid long naps close to your main sleep.
3. Shift bedtimes gradually when your roster allows, moving in small steps rather than big jumps.
4. Make your bedroom dark and quiet. Blackout curtains, an eye mask and earplugs tell your body it is night, even at noon.
5. Dim the screens. Bright light from phones and tablets before sleep can delay sleepiness. Use night mode, lower the brightness, or put the phone away. Wear sunglasses on the drive home after a night shift to reduce morning light exposure.

Eating tips

6. Prepare meals in advance. Cook in bulk, portion into containers and take a proper meal to work. Knowing you have food in your bag makes the vending machine far less tempting.
7. Choose snacks with protein and fibre. Sugary snacks give a quick lift and a crash. Better options: cheese on whole-grain crackers, an apple with peanut butter, a boiled egg and a handful of almonds, hummus with carrot sticks.
8. Drink water regularly. Thirst is easily mistaken for hunger. Keep a bottle with you, and go easy on caffeine in the last few hours before you plan to sleep.
9. Sit down, eat slowly and stop at about 80 percent full. It takes time for fullness signals to reach your brain. See eating slowly for weight loss. Many experts also suggest keeping meals lighter during the middle of the night.

Exercise tips

10. Build up to about 30 minutes, four or five times a week. If you are not exercising now, start with ten minutes and add a little each week. A brisk walk counts, and regular exercise can improve sleep quality.
11. On nights, keep it simple. A short bodyweight routine when you wake up is often more realistic than a gym trip. Try our 15-minute workout.
12. Train soon after waking, whatever your shift. It leaves less time for excuses. On nights, that might be 4pm; on mornings, a short walk before work; on afternoons, the gym at 9am.

Lessons from the 24-hour casino floor

Few workplaces show the reality of shift work as clearly as a Las Vegas casino. The floor never closes, so dealers, cocktail servers, security staff and cage cashiers work in three rotations that locals call day, swing and graveyard. A graveyard dealer might start at 2am under bright lights with no windows and no clocks, a design that is famously good at hiding what time it is. Many dealers rotate between tables on a fixed rhythm, often dealing for around an hour and then taking a break, and veterans describe using those breaks to stretch, walk and drink water rather than smoke or snack.

The principles are the same in a hospital or a warehouse: protect your sleep, bring your own food, and use every break to move. Visitors can learn from it too. The windowless, clockless casino environment makes it easy to stay up far later than planned, which wrecks the next day's eating and energy. We share practical ways to keep your body clock on track in Las Vegas in how to stay fit on a Las Vegas trip, and look at how tournament players manage marathon sessions in poker players' fitness at long tournaments.

A real-life style example

Take a nurse on a rotating roster: five mornings, two days off, five afternoons, two days off, four nights, three days off. Her plan: meal prep on the first day off of each block, a 20-minute walk or bodyweight workout soon after waking every work day, a short nap before each night shift, and a consistent seven-and-a-half-hour sleep window for each shift type. It is not perfect, and it does not need to be. Planning your days around your shifts makes it much easier to eat, sleep and move better.

Put it into your life
