Why Relaxing at Mealtimes Might Be the Missing Link to Better Digestion

We spend so much time focusing on what to eat.

But very little time talking about how we eat.

If there is one time of the day to intentionally relax, let it be during your meals.

Because digestion does not happen well in fight-or-flight mode.

It happens in rest-and-digest mode.


Understanding the Nervous System and Digestion

Your body runs on two main branches of the autonomic nervous system:


Sympathetic Nervous System

“Fight or flight”

This is the mode you’re in when:

  • You’re stressed

  • You’re rushing

  • You’re anxious

  • You’re answering emails

  • You’re scrolling while eating

  • You’re eating in the car

When this system is activated:

  • Blood is redirected away from the digestive tract

  • Stomach acid production decreases

  • Digestive enzymes reduce

  • Gut motility becomes irregular

  • Bloating and discomfort increase

Your body is prioritising survival instead of digestion.


Parasympathetic Nervous System

“Rest and digest”

Parasympathetic nervous system is responsible for:

  • Stimulating stomach acid

  • Releasing digestive enzymes

  • Coordinating gut motility

  • Supporting nutrient absorption

  • Promoting healthy bowel movements

This system is largely mediated by theVagus nerve — the communication highway between your brain and your digestive organs.

When the vagus nerve is stimulated, digestion improves.


Why This Matters (Especially If You Struggle With…)

  • Bloating

  • Reflux

  • IBS-type symptoms

  • Constipation

  • Feeling “heavy” after meals

  • Poor appetite regulation

  • Emotional eating

  • Hormonal imbalances

  • Autoimmune conditions


If You Only Relax Once a Day… Let It Be At Mealtimes

I often tell patients:

You don’t have to meditate for an hour. Just give your body 5 calm minutes before, during meals and after meals.

Even small shifts into parasympathetic activation can significantly improve digestive efficiency.


Practical Ways to Activate the Parasympathetic Nervous System Before Meals


Here are simple, realistic techniques you can use to calm your nervous system


The 4–6 Breathing Technique

Before eating:

  • Inhale through your nose for 4 seconds

  • Exhale slowly for 6 seconds

  • Repeat for 5–10 breaths

Longer exhales stimulate the vagus nerve and activate rest-and-digest mode.

This alone can reduce bloating dramatically in sensitive individuals.


Box Breathing

  • Inhale 4 seconds

  • Hold 4 seconds

  • Exhale 4 seconds

  • Hold 4 seconds

  • Repeat for 1–2 minutes and increase the number of second you do the exercise for (try up to 10 counts)

Simple. Effective. Evidence-based.


Hand-on-Belly Breathing

Place one hand on your chest and one on your belly.

Breathe so that:

  • Your belly rises

  • Your chest stays relatively still

This encourages diaphragmatic breathing, which directly improving vagal tone and digestive blood flow.


The “First Bite Pause”

Before your first bite:

  • Put your fork down

  • Take one deep breath

  • Notice the smell and appearance of the food

This triggers the cephalic phase of digestion — priming stomach acid and enzyme release.


Vagus Nerve Stimulation Techniques

Additional gentle stimulators:

  • Humming for 30 seconds before eating

  • Gargling water

  • Cold water on the face

  • Gentle neck stretches

  • Light abdominal self-massage

  • Pulling down lightly on your ears or lobes

These stimulate the vagus nerve and support parasympathetic tone.


Eat Without Multitasking

No:

  • Email

  • News

  • Stressful conversations

  • Work

  • Scrolling

Your nervous system does not know the difference between:

  • A threatening email

  • A lion

If you are stressed, digestion slows.


The Bigger Picture

When you consistently eat in a parasympathetic state, you may notice:

  • Less bloating

  • Better bowel movements

  • Improved fullness signals

  • Reduced cravings

  • Better blood sugar regulation

  • Improved hormonal balance

  • Reduced inflammation


Digestion is not just mechanical.

It is neurological!
