How Breathwork Can Calm Your Nervous System: Why Mums Feel Constantly "On"

Motherhood changes you in ways that are both beautiful and demanding. While we often talk about sleepless nights and the physical recovery after birth, we rarely talk about what happens to a mother's nervous system.

I’m Liadhán Child Sleep Consultant and Breathwork Coach in Ireland, founder of CulaBaby Sleep & Wellness, but first and foremost, I'm a mum of three.

Every week i meet parents who tell me they feel exhausted, overwhelmed and constantly 'on'. Many assume this is simply part of parenting, but there is real science behind why this happens.

My own journey into breathwork for mums came from lived experience. None of my children slept well and, although their sleep eventually improved with support, I still didn't feel like myself. The exhaustion continued. The mental load never seemed to switch off. I felt a huge shift in my body, both physically and mentally, and I was constantly on high alert.

That's when I started leaning into breathwork. The impact it had on my own wellbeing inspired me to train professionally as a Breathwork Coach in Ireland. Today I combine evidence-based sleep support with nervous system regulation because I know that when we support both the child and the parent, the whole family benefits.

Why Becoming a Mum Changes Your Nervous System

From the moment your baby arrives, something shifts.

Your brain becomes finely tuned to keeping your baby safe. You're listening for cries, watching feeding patterns, remembering appointments, thinking ahead and carrying the invisible mental load. Your nervous system is constantly scanning for what needs your attention.

This is completely normal. Your body is designed to respond to your baby.

Your baby wakes? Your nervous system responds.

Your baby cries? Your body activates.

Your baby doesn't settle? Cortisol rises.

Your toddler wakes at 5am? Your body moves into stress mode.

The challenge is that when sleep is broken night after night, your nervous system doesn't get the opportunity to reset.

Sleep isn't just important because you're tired. It's essential for calming and regulating your nervous system.

Cortisol Isn't the Enemy

Cortisol often gets a bad reputation, but it's an essential hormone. It helps you wake in the morning, stay alert, respond to challenges and care for your baby. The problem isn't cortisol itself. Cortisol is doing exactly what it was designed to do. The problem is that, in modern motherhood, we often don't come back down from that activated state.

How This Can Feel

You might notice anxiety, overwhelm, irritability, feeling stuck in fight, flight or freeze, difficulty sleeping even when your child sleeps, or simply feeling like you're surviving rather than thriving. These can all be signs that your nervous system needs support.

How Breathwork Helps Calm Your Nervous System

This is why I'm so passionate about breathwork for mums.

"Your breath is the only part of your nervous system you can consciously control.

That means you have a powerful tool to help bring your body back to a place of calm."

When we're stressed, overwhelmed, or constantly rushing from one thing to the next, our nervous system shifts into 'fight or flight' mode. Our breathing naturally becomes quicker and shallower, our heart rate increases, our muscles tense, and our body stays on high alert.

The amazing thing is that our breath can help change that.

When we intentionally slow our breathing—especially by making our exhale a little longer than our inhale—we gently stimulate the vagus nerve. The vagus nerve is a key part of the parasympathetic nervous system, often called our 'rest, digest and recover' system.

As we breathe more slowly, we send a message to the brain that we are safe. Our heart rate begins to slow, our muscles soften, and our body starts to move out of 'survival mode' and into a calmer, more regulated state.

This isn't about making stress disappear. It's about giving your body the opportunity to pause, reset, and recover—something every parent deserves.

"When your nervous system feels calmer, it's easier to respond instead of react. You feel more patient, think more clearly, and have a little more capacity to cope with the challenges of everyday family life."

Benefits of Breathwork for Mums

Regular breathwork can:

• Help calm your nervous system.

• Reduce feelings of stress and anxiety.

• Improve emotional regulation.

• Support deeper, more restorative sleep.

• Help you feel calmer at bedtime, benefiting both you and your child.

• Support recovery during the postnatal period.

I often encourage parents to use simple breathing techniques before bedtime, during sleep training, at 5am wake-ups or whenever they notice themselves becoming overwhelmed.

Everyday Breathing Matters / Functional Breathing 

“In everyday life, the best way to breathe is through your nose — nose in, nose out. Your nose is designed for breathing. It cleans, warms, and moistens the air before it reaches your lungs, helping your body breathe in a calmer and healthier way. . We breathe in oxygen, which passes from the lungs into the bloodstream. Carbon dioxide then helps oxygen leave the blood and enter the body's cells, where it is used to produce energy for everything the body does—from thinking and movement to healing, sleep, digestion, hormone production, and keeping the heart and brain working properly. The carbon dioxide produced by the cells is then carried back to the lungs and breathed out.

A lot of people think carbon dioxide is just a waste gas, but we actually need a healthy amount.

When we breathe too fast or too much through the mouth (faster, shallower or higher in the chest)  we can lose too much carbon dioxide, which can leave the body feeling more stressed, tense, and unsettled and not healthy . Slow nasal breathing helps the body feel calmer, safer, and more regulated.. This is why, outside of dedicated breathwork sessions, I always encourage nasal breathing throughout the day.

Gentle Breathwork Techniques I Teach

The breathwork I do in my sessions or when working with parents is gentle therapeutic breathing techniques to calm the nervous system. The practices include slow diaphragmatic breathing, longer exhales, and simple breath patterns designed to help your body move from a state of stress into one of rest and recovery. Learning how to feel relaxed even when life feels busy or overwhelming

Try this tonight : Restorative Breathing 

If you're feeling overwhelmed, constantly "on," or simply exhausted after a long day, I'd love you to try this simple restorative breathing exercise tonight.

Restorative Breathing focuses on slow diaphragmatic breathing, allowing the belly to gently rise and fall.

This is actually how we were designed to breathe. If you've ever watched a sleeping baby, you'll notice their little belly naturally rises and falls with each breath. As we grow older, stress, poor posture and the demands of everyday life often lead us to breathe higher in our chest instead. Over time, we can forget how to breathe in the calm, relaxed way our bodies were intended to.

Tonight, find somewhere comfortable where you won't be disturbed for a few minutes.

Place one or both hands gently on your belly.

Take a slow breath in through your nose, allowing your belly to expand naturally as the breath rises through your body. There is no need to force the breath—just let it fill you gently.

As you breathe out, simply let go. Allow the exhale to fall away naturally, releasing any tension you're holding.

Repeat this five times.

With each inhale, allow your belly to soften and expand a little more. With each exhale, imagine yourself letting go a little more—of the stress, the tension, the mental load and the busyness of the day.

There is no pressure to breathe deeply or perfectly. Simply allow your breath to return to the natural pattern your body was designed for.

Sometimes, the most powerful thing we can do is simply slow down, breathe, and give our nervous system permission to recover.

You Don't Need Hours

Even one or two minutes of intentional breathing can help interrupt the stress cycle. The goal isn't perfection—it's giving your nervous system regular opportunities to recover.

Final Thoughts

For years I believed I simply needed my children to sleep better. What I eventually realised was that I also needed to teach my own body how to feel safe, calm and rested again.

If you're feeling constantly 'on', know that you're not alone. Your body has been working incredibly hard to care for the people you love. With the right sleep support and simple breathwork techniques, it is possible to feel calmer, sleep better and restore balance.
