Voo Breathing: How to Use it in a Nervous System Reset or Trauma Release Ritual

Key Takeaways

• Voo breathing is a simple exercise combining slow belly breathing with a long, resonant “vooooo” sound on the out breath, developed by Dr. Peter Levine as part of his Somatic Experiencing approach.

• We chose voo breathing as the somatic technique for our latest Bloom Box bath meditation because of the science: it helps release stuck trauma patterns and reset nervous systems by activating the vagus nerve while you soak. Breathing exercises can also stimulate both the sympathetic and parasympathetic nervous systems.

• The deep “vooooo” sound creates vibration that stimulates the vagus nerve, signalling safety to your body, easing anxiety, regulating the nervous system, and supporting better rest and digestion. Voo breathing also enhances focus by managing the body's autonomic nervous system, which directly affects cognitive ability.

• This technique is gentle, accessible, and can be safely practiced in the bath for 3–10 minutes at a time.

• Below, we’ll explore the science behind it, teach you a step-by-step practice, and share tips for pairing it with your Bloom Box ritual meditation.

• We created a bath-friendly version of this practice inside our seasonal Bloom Box meditation.

What Is Voo Breathing?

For those of us (err, me) who need a constant nervous system reset when overwhelmed, voo breathing is the answer.

Voo breathing is beautifully simple: a slow, deep breath into your belly, followed by a long, sustained “vooooo” sound that activates the vagus nerve as you exhale.

The method was developed by Peter Levine, the American psychotherapist who founded Somatic Experiencing in the late 20th century. Through decades of clinical work, he discovered that this particular sound helps calm the body after stress and supports trauma resolution without needing to retell your story.

The sound itself is low and resonant. Think of a soft foghorn in the distance. It rises from your gut rather than your throat, creating gentle vibration through your chest, belly, and beyond. The idea isn’t perfection. It’s about creating soothing internal sensations and a sense of groundedness in your body.

For our Bloom Box meditation, we’ve adapted Peter Levine’s original technique into a bath-friendly version that feels natural while you soak.

Why We Brought the Voo Breathing Technique Into Our Bloom Box Bath Meditation: Vagus Nerve Stimulation

We wanted a body-based tool to help you down-shift out of fight-or-flight while you soak. Voo breathing does this by stimulating the parasympathetic nervous system.

The bath already begins the work of regulating the nervous system. Warm water relaxes muscles and blood vessels. Lowered sensory input—candlelight, scent, quiet—signals to your nervous systems that you can slow down. The voo breath technique adds a powerful layer on top of that, directly communicating with your nervous system and vagus nerve through sound and vibration.

There’s something special about the acoustics, too. The humming “voo” sound travels through water and tiled space, creating an enveloping, contained feeling. Many in our Canada and worldwide community are working with anxiety, burnout, or trauma history. We wanted a practice that doesn’t require talking about feelings or the story of what happened, just gentle release through the body.

Our Spring 2026 Bloom Box: Awakened Alignment was intentionally designed around nervous system repair, with voo breathing and orienting as the central somatic tools in our recorded meditation. This is the hope we hold: that you can explore healing in your own space, at your own pace.

The Science: How Peter Levine's Voo Breath Technique Helps Trauma Release And Nervous System Reset

Voo breathing works primarily through the vagus nerve and your body’s stress-response systems.

The vagus nerve is a long cranial nerve running from your brainstem through your throat, heart, lungs, stomach, and gut. It governs “rest and digest” functions: slowing heart rate, reducing stress, deepening breathing, enhancing digestion, and helping reduce inflammation.

When you make that low “vooooo” sound, the vibration stimulates the vagus nerve along its entire pathway. This can:

• Slow your heart rate

• Deepen your breath naturally

• Reduce stress hormones like cortisol

• Help regulate emotions and sensations

After traumatic or chronic stress, the nervous system often gets stuck. It's either in high alert (racing thoughts, tight muscles, shallow breath) or shutdown (numbness, dissociation, fatigue). Vagal stimulation through voo breathing helps bring you back toward a calm middle range. The technique can be practiced for 3-5 minutes to stimulate positive changes in neurochemistry.

Research trends support this: studies on prolonged exhalation and vocal toning show a reduction in stress due to cortisol reductions of 20–30% after just a few minutes. Heart rate variability improves. Humming can also increase the production of nitric oxide in the body, improving blood flow and reducing inflammation. Moreover, the voo breathing method can help you feel safe, reduce inflammation, regulate your heart rate, and support your digestion. And because trauma is stored not only in memories but also in muscle tension, breathing patterns, and gut reactions, voo breathing gently loosens these body-held patterns. The science is clear: this practice can enhance your mental health and overall wellbeing while aiding in trauma resolution.

Step-by-Step: A Simple Exercise to Practice Voo Breathing In The Bath & Reduce Stress

Safety and comfort come first. Ensure your water temperature is comfortable (around 37–39°C), your body is well supported, and you won’t fall asleep fully underwater.

If you want a simple guide, follow our audio meditation for a somatic bath experience:

Setting up:

• Settle into your bath with feet or back against the tub

• Let your shoulders drop, soften your face

• Dim the lights or light your Bloom Box massage candle

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

• Play our recorded audio meditation for a fully guided bath somatic reset experience

Before you begin:

Breathe naturally for 3–5 breaths. Simply notice your belly rise and fall. No need to change anything yet—just awareness.

The voo breath:

• Inhale slowly through your nose, letting your belly expand like a gentle balloon

• Keep shoulders relaxed, tongue soft, face at ease

• Exhale with a deep, sustained “voooooo” sound on the out breath

• Aim for a low tone that creates subtle vibration through your chest, belly, and throat

The rhythm:

Take 1 slow inhale, fully filling your lungs, 1 long “voo” exhale, then 1–2 normal recovery breaths. Repeat for 6–10 rounds, about 3–5 minutes total. Listen to your body. If you feel dizzy, pause and rest.

Experiment with volume and pitch. Quieter, lower sounds often feel more grounding. This isn’t about performing, though. It’s about what helps you feel safe and present in your body.

Pairing Voo Breathing With The Bloom Box Ritual

Imagine the full scene: bath salts dissolving, botanicals floating, candle flickering, soft, gentle music playing with guided instructions for nervous system reset. You’ve soaked for five minutes, letting the warmth fill your muscles. Now you’re ready for the guided voo breathing audio.

As you follow the audio instructions, synchronize your voo breaths with the sensory elements. Inhale the scent of your bath blend. Notice water on your skin. Let the “voo” sound resonate with the candlelight and steam in your space.

Our recorded meditation gently cues when to breathe, when to rest in silence, and when to notice shifts in sensation. You don’t have to remember the steps! Just follow along and reflect on what you experience.

A closing ritual:

End with 3 quiet breaths without sound. Notice how your body now feels compared with the start of the session. Perhaps place a hand on your heart with a simple phrase: Right now, I'm safe.

Trauma Sensitivity, Safety, And When To Modify The Practice

Breathing exercises can provide a much-needed break for the brain and body, especially for trauma survivors, because breathwork helps to reduce stress.

However, for some people with trauma histories, even gentle body practices can bring up unexpected emotions or sensations. This is normal, so it’s important to go slow.

Start gently:

• Try just 2–3 “voo” exhalations your first time

• Relax on the out breath

• Allow plenty of normal breathing between rounds

• Stop if you feel overwhelmed, dizzy, or emotionally flooded

It’s okay if emotions, tears, or tingling sensations arise. The goal is never to force a catharsis. Stay within a tolerable window of presence.

Grounding modifications:

• Keep eyes open, softly focused on a candle

• Place a hand on the rim of the tub for sense of support

• Shorten the exhale if long “voo” sounds feel too intense

• Focus on the feel of water or contact with the tub

Please note that voo breathing is a supportive wellness tool, not a replacement for therapy or counselling. If you’re actively working through trauma with clients of a therapist, share this practice with them before using it more deeply.

Integrating Voo Breathing Beyond The Bath

Once you feel comfortable with voo breathing in the bath, carry it into everyday moments.

Examples:

Even a single slow “voo” exhale can signal your body to pause and assess: Is this situation actually dangerous, or just stressful?

Pair voo breathing with other gentle regulation tools: feeling feet on the floor, stretching neck and shoulders, or placing a warm compress on your chest.

Consider keeping a brief journal, noting date, mood before and after, and body sensations. Over a few weeks, you may notice how your nervous system responsiveness changes. This simple practice becomes a portable reset, reminding your body: Not dangerous now.

FAQ

How often can I practice voo breathing in the bath?

We recommend practicing voo breathing in the bath 2–3 times per week, for about 3–10 minutes each session. More isn’t always better. Nervous systems respond well to regular, gentle repetition rather than long marathons. On non-bath days, try a shorter 1–3 minute session seated or lying down. Using a guided meditation like ours can help you achieve calm and balance.

Can children or teens use voo breathing with the Bloom Box ritual?

Older children and teens can enjoy a playful version of voo breathing. Always supervise baths and check water temperature. Keep it light and brief. Just a few “voo” sounds. Avoid it if they feel silly in a way that disrupts comfort. We suggest families try the practice themselves first to model calm.

What if I feel more anxious when I focus on my breath?

Some people with anxiety or trauma may initially feel uneasy focusing on breathing. Try smaller, softer breaths and shorter “voo” sounds. Focus on external anchors such as sounds in the room, feel of water, contact with the tub. Discontinue and consult a healthcare provider if anxiety consistently worsens.

Is voo breathing safe during pregnancy or with heart conditions?

Voo breathing is generally gentle, but any practice changing breathing patterns should be discussed with your healthcare provider during pregnancy or with cardiac or respiratory conditions. Keep the new breath easy, so no straining. Stop immediately if lightheaded. A nurse, doctor, or midwife can offer personalized guidance of course.

Do I need the guided audio, or can I practice on my own?

You can absolutely practice voo breathing on your own. Our guided Bloom Box meditation provides structure, pacing, aromatherapy benefits, and supportive language that many find helpful when beginning. We encourage you to experiment: try the guided track a few times, then adapt to your own rhythm. Leave your comments below if you have questions about voo breathing. We’d love to hear from you.

Can voo breathing replace therapy for trauma release?

No, voo breathing is not a substitute for therapy, and we are not trained therapists. We are simply educating about somatic experiences that can help release trauma alongside professional therapy. For more education about trauma release, visit a mental health practitioner near you.
