Sleepless nights and stomachaches: how night shift work affects digestive health

The vending machine hums softly. A monitor beeps in the background.

You take another sip of lukewarm coffee, trying to convince your body it’s morning when it knows it’s not. Your gut tightens again, that familiar heaviness that comes with night shifts.

If you’ve ever worked through the dark hours, you know the ache isn’t just in your back or your eyes. It’s in your stomach too. That uneasy, off rhythm feeling that makes food taste

Strange and sleep Feel impossible.

Shift work doesn’t just flip your schedule. It rewrites your biology.

Your digestive system depends on rhythm, a 24-hour cycle that tells your body when to rest, when to eat, when to heal. Working through the night throws that rhythm off. It’s like your body’s an orchestra with no conductor. Meals come at odd hours. Breaks are rushed. Hydration slips. The result? A system that’s overworked and under-supported.

But the good news is that your gut is resilient.

With a few intentional shifts, you can ease discomfort, restore balance, and even help your body thrive while the world sleeps.

So, pour something warm and soothing into your favourite

Yeti Mug, find a quiet moment, and let’s walk through what’s really happening beneath the surface and how to make the night shift easier on your body, your mind, and your gut.

Understanding How Night Shifts Affects Digestion

How the Night Shift Scrambles the System

Your body runs on rhythm. It knows when to rise, when to rest, and when to digest. But when you flip that schedule, your gut doesn’t always get the memo.

Night shifts pull you out of sync with your circadian rhythm, the internal clock that coordinates everything from hormones to metabolism. When that rhythm slips, digestion can become unpredictable. Meals that once felt easy can suddenly leave you bloated, queasy, or running for the bathroom at 4 a.m.

Research backs what many of us already know. A five-year study in the Scandinavian Journal of Work, Environment, and Health found that healthcare workers who regularly worked nights were more likely to experience increased BMI and abdominal obesity. Another study in the Annals of the New York Academy of Sciences found that shift work can weaken the intestinal lining, leading to inflammation and discomfort. And in the British Journal of Nutrition, researchers showed that even mild dehydration, something common on long night shifts, affects mood and digestion.

Here’s where small shifts make a big difference:

Hydrate early and often with your Stanley Thermos, Keep meals consistent and easy on your stomach. Dim lights, breathe deeply, and give your body cues to rest. Night work may confuse the system, but it doesn’t have to break it. Your gut is adaptable, and with rhythm, hydration, and grace, it will find its way again.

Common Gut Traps of the Night Shift

At some point in every shift, your stomach speaks louder than your thoughts. It’s not hunger exactly, it’s that uneasy mix of fatigue, emptiness, and stress. Here are some of the biggest digestive traps and how to step around them:

Acid Reflux: Eat smaller, lighter meals, and avoid greasy or spicy foods.

Keep a Rubbermaid Container with something easy to digest.

Bloating: Slow down, chew thoroughly, and move between tasks. A warm drink in yourYeti Cup can ease discomfort. Constipation: Drink regularly from your Stanley Thermos, add fiber, and stretch gently before the end of your shift. Unusual Bowel Rhythms: Eat at consistent times and listen to your body’s cues.
