Vagus Nerve Exercises: 7 Calming Practices and What They Do
The most reliable vagus nerve exercise is slow breathing: in through your nose, into your belly, and out through your mouth, for at least five minutes. Humming, gentle movement, cold on the face and muscle relaxation are the other common options. They work mainly by helping your body relax. They do not “reset” or “repair” a nerve, whatever social media says. Below you will find how to do each one, what the evidence supports, and when to talk to a doctor instead.
TL;DR
Slow, diaphragmatic breathing for five minutes or more is the best-supported practice, and the NHS publishes a simple version.
Humming, gentle exercise, cold on the face and progressive muscle relaxation are sensible additions, mostly working through relaxation.
Claims that a single trick “resets” the vagus nerve are unsubstantiated, so treat these as calming habits, not treatments.
Stop if you feel dizzy or faint, and see your GP for fainting, palpitations or anxiety that keeps returning.
If the same tension keeps coming back, working with the emotional roots can help alongside these exercises.

What “stimulating the vagus nerve” actually means
The vagus nerve is the main pathway of the parasympathetic nervous system, the part that slows your heart and helps you settle after stress. When people talk about “vagal tone”, they usually mean how readily your body shifts from alert to calm. One common way researchers look at this is heart rate variability (HRV), the small beat-to-beat changes in your pulse.
So “vagus nerve exercises” is a popular label for anything that nudges your body towards that calmer state. It is worth being straight about the limits. A McGill University article on the topic says claims that simple exercises reset the vagus nerve are unsubstantiated, and that such activities, if helpful, most likely work through relaxation. That is not a reason to skip them. Relaxation is genuinely useful when you are overwhelmed. It simply means you can choose whichever calming practice you will actually do.
Exercise 1: Slow diaphragmatic breathing
This is the one to start with, because it has the strongest backing and costs nothing. The NHS breathing exercise for stress, anxiety and panic says to sit in a chair that supports your back, or lie on a bed or yoga mat. If you lie down, keep your legs straight or bend your knees so your feet are flat.
Here is how to do it:
Get comfortable and let your shoulders drop.
Place one hand on your upper chest and the other on your stomach, just above your belly button. NHS guidance from Mersey Care describes the goal as your stomach rising as you breathe in through your nose and falling as you breathe out, with very little movement in the upper chest.
Breathe in gently through your nose, letting the breath flow into your belly without forcing it.
Breathe out through your mouth.
Keep going for at least five minutes, and repeat regularly.
Two details from the research are worth knowing. A systematic review of breathing practices for stress and anxiety found that effective practices avoided fast-only paces and sessions shorter than five minutes. So rushing through three breaths in a queue is fine as a pause, but the real benefit comes from a proper sitting. The same review also noted that involuntary tension in the diaphragm can make an otherwise promising practice ineffective. If your belly feels stuck, soften your stomach, loosen waistbands and try lying down rather than pushing harder.
How often should you practise?
The NHS suggests at least five minutes, done regularly. A sensible routine is once in the morning and once before bed, with a short round whenever you notice your shoulders creeping up. Linking it to something you already do, such as the kettle boiling, makes it stick.
Exercise 2: Longer outbreaths and 4-7-8 breathing
Once belly breathing feels natural, you can try a pattern. In 4-7-8 breathing you breathe in for four counts, hold for seven and breathe out for eight. A 2025 scoping review of 15 studies published between 2013 and 2024 found that it may reduce stress and anxiety and may influence parasympathetic activity through vagal pathways. The evidence is early, so see it as a promising technique rather than a proven one.
If you hold your breath and feel light-headed, shorten the counts and keep the same ratio. Comfort matters more than the numbers. Breathing patterns are also useful when frustration, not worry, is the problem, and these three breathing exercises to calm anger fast show how a slower outbreath can take the heat out of a tense moment.
Exercise 3: Humming, singing and chanting
Humming lengthens your outbreath almost automatically, and it is easy to do in the car or the shower. Breathe in through your nose, then hum on the out-breath for as long as is comfortable. Repeat for a few minutes. The vibration is often described as soothing, and the slow exhale is the likely calming ingredient.
I would not claim humming has been proven to raise vagal tone. What we can say is that it is a pleasant way to slow your breathing, and slow breathing is the part with evidence behind it. A narrative review of studies from 2012 to 2025 reports that slow, nasal, diaphragmatic breathing significantly improves vagal tone, HRV, parasympathetic activity and emotional control. Humming through your nose fits that pattern neatly.
Exercise 4: Gentle movement and regular activity
Moving your body is another route. Moderate exercise programmes, such as those used in cardiac rehabilitation, are documented to increase HRV and vagal activation. You do not need to train hard. A brisk walk, a swim, a bike ride or a gentle yoga session several times a week all count.
The point is regularity. A short walk after a stressful day often shifts your mood more than a single intense session, and it pairs well with the breathing above: try breathing in for four steps and out for six as you walk.
Exercise 5: Cold on the face and fresh air
UK pulmonary guidance from the Primary Care Respiratory Society’s desktop helper lists facial cooling, mindfulness or meditation and relaxation techniques as non-drug approaches, and notes that airflow over the face is thought to stimulate a vagal response. In everyday terms: splash cool water on your face, hold a cool flannel to your cheeks, or open a window and let air move across your face while you breathe slowly.
Keep it gentle. Cold water on the face is very different from a full cold plunge, and anyone with a heart condition or blood pressure problems should ask their GP before trying cold exposure of any kind.
Exercise 6: Progressive muscle relaxation
Tension and breath are closely linked, so releasing the muscles helps the breathing settle. NHS mental health guidance on the T.I.P.P. technique includes progressive muscle relaxation, tensing muscles from the face down to the toes so you can tell the difference between tension and relaxation.
Try it lying down. Tense each area for a few seconds, then release fully: face, jaw, shoulders, arms, hands, stomach, legs and feet. Let your out-breath carry the release. Many people find this easier than breathing work if their mind is racing, because it gives the attention something physical to follow.
Exercise 7: Meditation, mindfulness and connection
Mindfulness and meditation appear alongside facial cooling in the UK respiratory guidance above, and many people find a short body scan or a loving-kindness practice the easiest way to stay with slow breathing. Time with people you trust, laughter and feeling safe in company also help the body wind down, though these are harder to measure. If you want more structure, our guide to mindfulness for anxiety covers how to begin, and our guided meditations are there if you would rather be led.
What the evidence does and doesn’t show
The breathing evidence is encouraging. The systematic review mentioned earlier found that 54 of 72 breathing interventions were effective for stress or anxiety, and that effective practices were associated with greater parasympathetic tone. A study of diaphragmatic breathing combined with physical touch, summarised in the narrative review, reported decreased cortisol.
There are limits. Experts warn that popular “vagus nerve reset” tricks, such as particular eye movements, often lack scientific validation, and that much of the benefit comes from the well-established calming effect of relaxation. Be wary of anyone who promises a quick fix for a diagnosed condition.
It also helps to separate home exercises from medical vagus nerve stimulation. The 2023 Royal College of Physicians stroke guidelines say people with mild-to-moderate arm weakness after stroke may be considered for transcutaneous vagus nerve stimulation alongside usual therapy, while the best dose and settings remain unclear. That is a clinical device used under specialist care. Breathing and humming are not a substitute for it, and they cannot repair a damaged nerve.
Doing them safely, and when to see a doctor
For most healthy adults, slow breathing, humming and gentle movement are low risk. A few sensible rules:
Stop if you feel dizzy, tingly or faint. Return to normal breathing. Overdoing deep breaths can leave you light-headed, so keep the breath gentle.
If you feel faint, sit or lie down with your legs raised. Hospital advice on vasovagal syncope also suggests squeezing your arm, leg, stomach and buttock muscles until the feeling passes, and getting up slowly afterwards.
See your GP if you faint, have palpitations, chest pain or breathlessness you cannot explain, or if anxiety, low mood or poor sleep is affecting daily life. Use 111 for urgent advice, and 999 in an emergency.
Check first if you have a heart rhythm condition, low blood pressure, asthma or another breathing condition, are pregnant, or take medication affecting your heart, before trying breath holds or cold exposure.
These practices complement medical care. They never replace it.
Our perspective
When someone comes to us after reading about their “vagal tone”, what they usually describe is a body that cannot switch off. They are tense, tired and braced, and often there is an old emotional story underneath it. We think breathing and gentle practices are a good foundation, and we teach them. But we have also seen that when a pattern is rooted in past experience, a few minutes of breathing may take the edge off without touching the cause. That is where our work comes in. Our sessions combine Quantum Healing Hypnosis (QHHT) with energy work, in a calm, trauma-informed space where you are never rushed. Many clients tell us they felt supported and that the session was tailored to them. We do not offer this as a replacement for medical care, and we always encourage you to see your GP for physical symptoms. Think of it as a way to explore what your body keeps holding onto, alongside the exercises above. Paul
Build a daily routine that lasts
A realistic plan beats an ambitious one. Here is a simple starting week:
Time | Practice | Length |
Morning | Belly breathing, seated | 5 minutes |
Midday | Walk with longer outbreaths | 10 to 20 minutes |
Evening | Progressive muscle relaxation in bed | 5 to 10 minutes |
Any stressful moment | Humming or cool water on the face | 1 to 2 minutes |
After a week, notice what changed. Is your jaw less tight, are you sleeping a little better, do you recover faster after a difficult conversation? Keep what helps and drop what doesn’t. Our seven day anxiety self help plan and our guide to nervous system regulation give you more structure if you want it, and the 90 second body reset for rumination is handy for late-night worry.
When self-help isn’t enough
If you have practised for several weeks and still feel overwhelmed, blocked or stuck in the same emotional loop, you are not doing it wrong. Some patterns need more than breathing. Paul works with clients in Orpington and across Bromley, Croydon, Bexley, Sutton, Lewisham and Greater London.
A QHHT session is £369, or £399 as a mobile session where Paul comes to you. It is an extended session designed to reach the deeper subconscious mind.
An Evolve Quantum Healing session, combining Reiki and energy work, is £99, and a remote version is also £99.
Our Rising Higher online course offers structured exercises and video content for anxiety and low mood.
If you are unsure which suits you, start with the energy healing session, or read about QHHT and regression hypnotherapy first.
FAQ
What is the best exercise to activate the vagus nerve?
Slow diaphragmatic breathing has the strongest support. Breathe in through your nose into your belly and out through your mouth for at least five minutes, as the NHS describes. Do it regularly rather than occasionally for the best chance of feeling a difference.
Can you reset or repair the vagus nerve with exercises?
No. Claims that simple exercises reset the vagus nerve are unsubstantiated, and the benefit most people feel comes from relaxation. If you have symptoms that worry you, such as fainting or persistent digestive or heart symptoms, see your GP rather than relying on exercises.
Can the vagus nerve affect sleep?
Slowing your breathing and relaxing your muscles before bed can help you wind down, which is why many people use them for sleep. Poor sleep has many possible causes, though, so speak to your GP if it continues for weeks.
Are vagus nerve exercises safe?
Gentle breathing, humming and walking are low risk for most people. Stop if you feel dizzy or faint, and check with your GP first if you have a heart, blood pressure or breathing condition, particularly before breath holds or cold exposure.
