Eating well on shifts and night shifts

4 min read

Working shifts — especially rotating or night shifts — pushes your meals out of sync with your body clock, which can affect energy, appetite and digestion. You can't always eat at the 'normal' times, so the aim is a rhythm that works for your shift, not perfection.

On a night shift, try to eat a proper meal before you start, then a smaller, lighter meal or snack partway through the night rather than one big heavy meal at 3–4am — large, rich meals overnight tend to sit heavily and leave you sluggish. Keep balanced options within reach: things with protein and fibre (yogurt, nuts, wholegrain sandwiches, fruit, leftovers) steady your energy far better than sugary snacks or vending-machine food.

Caffeine helps early in a shift but can wreck the sleep you need afterwards. A useful habit is to stop caffeine several hours before you plan to sleep, and switch to water for the second half of the shift. Staying hydrated also curbs the mindless snacking that long nights encourage.

When your shifts rotate, keep meals roughly anchored to your new 'day': a first meal after you wake, regular meals across your waking hours, and a lighter one before you sleep. Prepping food in advance means you're not relying on whatever happens to be open at 4am.

This is general wellbeing information, not medical advice. Shift work can affect blood sugar, weight, mood and heart health over time; if you have a health condition, are pregnant, or notice ongoing problems with energy, digestion or sleep, talk to your doctor or an occupational-health service about what's right for you.
