Stress and Gut Health: Everyday Habits to Support Digestion

Reading time: 5 minutes.

Last updated: 01 September 2025

Stress and gut health are closely linked through the brain-gut axis. If you’re noticing stress-related stomach problems and IBS flare-ups, small daily changes can help. This guide demonstrates how to calm a nervous stomach, utilise diaphragmatic breathing for bloating, and incorporate simple relaxation techniques to support digestion. On days when stress also shows on your skin, our sensitive skin guide can help.

How stress affects your gut

Your brain and gut are in constant conversation. During stressful periods, hormones and neurotransmitters shift how the gut moves and digests food. Some people’s digestion speeds up while others’ slows down, which can lead to symptoms like diarrhoea, bloating, pain, or constipation.

Stress can also nudge the body away from the “rest and digest” response, increasing intestinal permeability and local inflammation, and it may disturb the balance of gut bacteria (dysbiosis). Many people simply describe this cluster of sensations as a nervous stomach or stress-related stomach pain.

Stress does not only affect digestion. It can also influence sweating, skin balance, and even body odour. Our article on high cortisol and body odour explains how stress hormones play a role.

How to calm and support a nervous stomach

Begin with a brief pause before meals. Sit tall, rest your feet, relax your shoulders and take six to ten slow breaths. A warm drink, such as plain hot water or a mild herbal tea, can cue the body to slow down. Keep portions modest and chew longer than you think you need, setting cutlery down between bites. After eating, give yourself a few screen-free minutes so your system can switch fully into “rest and digest”. A short, gentle walk often eases tightness or upper-abdominal tension.

Support your microbiome

Your midday meal is one of the best opportunities to nourish your gut microbiome, the community of beneficial bacteria living in your digestive tract. Prebiotic-rich foods, such as asparagus, onions, leeks, bananas, and whole grains, feed these good bacteria, helping them thrive. Combining them with probiotic sources like live yoghurt, kefir, sauerkraut, miso soup, or kombucha adds beneficial strains directly to your system and helps create a balanced environment in your gut.

For extra support, include colourful veg, beans or lentils, and a drizzle of extra virgin olive oil for fibre and polyphenols, drawing from brightly coloured fruits and vegetables like berries, apples and onions, drinks such as black tea and coffee, and other sources including dark chocolate, nuts especially hazelnuts and pecans, seeds like flax and sesame, spices such as turmeric, cinnamon and cloves, and plenty of beans.

Breathing exercises for bloating

Diaphragmatic (belly) breathing can settle the upper abdomen and support motility. Place one hand on your chest and one on your belly. Breathe in through your nose so the belly rises more than the chest, then exhale slowly through pursed lips. Repeat for about ten breaths before or after meals. If you’d like a simple day-to-day plan that includes this type of exercise, see our simple daily stress relief routine.

Relaxation techniques to support digestion (10-minute routine)

A short routine once or twice a day is enough. Start with posture and a one-minute pause, then add a warm sip and a minute or two of belly breathing. Take your time while eating. Chew slowly, take smaller bites, and savour each mouthful. Finish with a few quiet minutes before you return to screens (phone, TV, etc). This kind of support for digestion lowers background tension and reduces the impact of stress on IBS symptoms. If discomfort persists or worsens, speak with your GP.

Create a sensory-friendly mealtime routine

If smells, textures, or noise raise stress in neurodivergent individuals, it helps to opt for neutral flavours and familiar textures, keep portions smaller, and eat in a quieter spot when possible. Predictable routines also make a difference, such as using the same seat, the same cup, and a consistent mealtime setup. A simple sensory toolkit, like soft clothing, headphones, or a preferred drink, can add comfort. These small adjustments ease the overall load, giving digestion a calmer setting to work in.

How meal timing can calm your system

Gentle changes to timing are often enough to ease discomfort. Try bringing dinners a little earlier, or allow a longer gap before bedtime, so your body has time to settle. Loosen tight waistbands to reduce pressure and make sitting more comfortable. If caffeine tends to worsen symptoms, consider moving it earlier in the day or swapping it for a soothing herbal tea in the evening. Eating regular, balanced meals feels calmer than relying on large, infrequent ones, giving the digestive system a steadier rhythm to work with.

Develop a consistent habit

Start tiny. Add one habit for a week, then another, and pair each with something you already do, perhaps ten belly breaths before opening your laptop or a warm drink before dinner. Over time, these everyday stress management habits become natural, rather than forced. Many people also like a small sensory cue in the evening, such as a Outboard Water Pump Impeller for Mercury/Voyager/Yamaha 689-44352-02 (Black) before bed. Try it after your breathing practice to mark the wind-down. For a wider plan across your day, explore our hub of everyday stress management habits in our Gloves.
