The simplest vagus nerve exercise is a slow breath with a long breath out. Breathe in for 4 counts and out for 6, for about 5 minutes. Research links slow breathing to higher heart rate variability, a sign your rest-and-digest system is active. Qigong adds sound, standing and slow neck and spine movement to the same breath.

What is the vagus nerve?
The vagus nerve is the main nerve of your rest-and-digest system. It links your brain to your heart, lungs and gut, and it carries messages both ways. A 2018 review in Frontiers in Psychiatry (Breit and colleagues) calls it the main part of the parasympathetic nervous system. It helps control mood, digestion, heart rate and the immune response.
The same review notes that vagal tone is linked to how well you handle stress, and that breathing can change it. That is why most vagus nerve exercises start with the breath.
How do you stimulate the vagus nerve?
You can't touch the vagus nerve, but you can work with it through your breath. When you breathe in, your heart rate goes up a little. When you breathe out, it slows down. A long, slow breath out moves your body toward rest and digest.
In Chinese, the word for breathing is 呼吸 (hū xī, say "hoo shee"). 呼 means to breathe out and 吸 means to breathe in. The breath out comes first, and in these exercises it matters most.
Does slow breathing really affect the vagus nerve?
The research points that way, with limits. Here is what we found when we read the studies ourselves.
| Study | What they did | What they found |
|---|---|---|
| Zaccaro and colleagues, 2018, Frontiers in Human Neuroscience | Reviewed 15 studies of breathing slower than 10 breaths a minute in healthy people | Slow breathing raised heart rate variability and was linked to more relaxation and less anxiety and anger |
| Balban and colleagues, 2023, Cell Reports Medicine | A one-month randomized study of 5 minutes of daily breathwork or mindfulness meditation | Breathing with long breaths out (cyclic sighing) improved mood and slowed breathing more than meditation did |
| Woo and Kim, 2025, Physiology and Behavior | 16 healthy adults tried slow breathing and humming breathing | Both raised heart rate variability compared with rest, and both felt relaxing |
| Kim and colleagues, 2026, Applied Psychophysiology and Biofeedback | 24 healthy adults compared humming with deep breathing | Humming slowed the breath to about 6 breaths a minute. The authors think the long breath out, not the buzzing sound, drives the effect |
| Gunawan and colleagues, 2026, Complementary Medicine Research | Pooled 15 studies of tai chi and qigong in beginners | Moderate gains in heart rate variability. The authors say the evidence is still limited |
Heart rate variability is the small change in time between heartbeats. Higher is usually a sign of a calmer, more flexible nervous system. Most of these studies were small.
6 qigong exercises for the vagus nerve
This routine takes about 10 to 12 minutes. Stand in loose clothes, or sit if standing is hard for you. Use one breath for the whole routine: in through your nose for 4 counts, then out slowly for 6 counts. The breath out is always longer than the breath in.
| Exercise | Main focus | Time |
|---|---|---|
| 1. Cleansing breath | Long breath out | 2 minutes |
| 2. Standing belly breath | Slow breath into the lower belly | 2 minutes |
| 3. Healing sound "Shoo" | Sound on the breath out | 2 minutes |
| 4. Heavenly Pillars | Spine and neck wave | 6 to 8 rounds |
| 5. Turtle Looks Behind | Neck and upper back twist | 3 rounds each side |
| 6. Tilting | Side of the neck | 3 to 4 rounds each side |
- Cleansing breath (2 minutes). Breathe in through your nose and feel your belly and lower back expand. Breathe out slowly through slightly pursed lips, as if through a straw. Do 4 counts in and 6 counts out. This is the core of every vagus nerve exercise.
- Standing belly breath (2 minutes). Stand with your feet shoulder width apart and your knees soft. Let your tailbone feel heavy and the top of your head float up. Put your tongue on the roof of your mouth. Rest your hands on your lower belly, just below the navel. Breathe deep into your belly, then let the breath rise into your ribs. As you breathe out, let your belly draw in. This still standing is called Zhan Zhuang.
- Healing sound "Shoo" (2 minutes). Breathe in and call up a feeling of kindness. Then breathe out slowly with a long, soft "Shoooo." This is "Xu," the liver sound from the Six Healing Sounds, the one we teach most for modern stress. Do it 6 times. The sound keeps your breath out long and steady. You can also hum a soft "mmm" on the breath out. Follow the video above for all six sounds.
- Heavenly Pillars (6 to 8 rounds). As you breathe in, tilt your pelvis and your chin slightly back to open the front of your body. As you breathe out, tuck your pelvis and your head and round your back. Keep your spine long and move like a slow wave.
- Turtle Looks Behind (3 rounds each side). Spiral your arms outward, thumbs leading, and twist your upper body to look behind you. Breathe out as you turn. Breathe in as you come back to center, spiraling your arms inward. Switch sides.
- Tilting (3 to 4 rounds each side). Hold one hand with the fingers together, palm turned in toward your armpit. Press the other palm down toward the floor with the fingers spread. Breathe out and tilt your ear toward the side with the fingers together. Breathe in and come back to center. Switch sides. Keep your shoulders away from your ears.
To close, rest both hands on your lower belly and take five slow breaths. In our classes we call this storing the energy.
Why add neck movements?
We did not find a study that shows neck movements alone stimulate the vagus nerve, so we won't claim it. We add them for two reasons. First, each one is done on a long breath out, which is the part the research supports. Second, a tight neck and upper back make slow, deep breathing harder. Moving the spine like a wave frees the fascia, the web of connective tissue that wraps every muscle, so the breath can sink low.
Move slowly. If a movement makes you dizzy or hurts, make it smaller or skip it.
Can you reset your vagus nerve?
Not with one trick. There is no reset button. What you can do is shift your body toward rest and digest each time you practice. A long breath out can help within minutes. In the Balban study, people practiced 5 minutes a day for a month. Think of it as training, not a quick fix.
How does qigong see the vagus nerve?
Chinese medicine does not name the vagus nerve. It talks about qi, the organs and the emotions instead. But the two maps line up in a useful way. The vagus nerve links the brain to the heart, lungs and gut. Qigong works on those same organs through breath, sound and movement.
At White Tiger Qigong we teach this through the Three Harmonies: Jing (body), Qi (breath) and Shen (spirit). The stance and neck work are the body. The long breath out is the breath. Your calm, steady attention is the spirit. It becomes qigong when all three work together. For more on the science of sound, read Do the Six Healing Sounds really work?
How often should you do vagus nerve exercises?
Once a day is ideal. Five to ten minutes you do every day does more than a long session you skip. When stress spikes during the day, just do Step 1 for one minute.

Is it safe?
For most people, yes. Never force the breath or hold it. If you feel lightheaded, go back to normal breathing. Qigong is a complementary practice. Use it alongside regular medical care, never instead of it. If you have a heart condition, a breathing problem, a neck injury or ongoing anxiety, check with your doctor before you start.
