The Vagus Nerve and Its Role in Emotional Regulation

The vagus nerve is the longest cranial nerve in the body, connecting the brain to major organs, including the heart, lungs, and digestive system. It plays a key role in the parasympathetic nervous system, which controls rest, digestion, and emotional regulation. The vagus nerve is responsible for sending signals between the brain and the body, influencing how we feel, how we respond to stress, and how we recover from emotional experiences.

20-Minute Vagus Nerve Activation Through Laughter Session

Objective:
This session is designed to stimulate the vagus nerve through laughter exercises, breathwork, and vocalization techniques. Laughter naturally activates the parasympathetic nervous system, helping to reduce stress, regulate emotions, and create a sense of safety and connection—crucial for actors stepping into vulnerable spaces.

1. Setting the Tone (2 minutes) – Grounding & Breathing

• Find a comfortable position, either seated or standing in a relaxed posture.
• Close your eyes or keep a soft gaze.
• Take a deep inhale through the nose for 4 counts, hold for 4, and exhale slowly through the mouth for 6 counts. Repeat 3 times.
• Set the intention:

“Laughter is a powerful tool for relaxation and creativity. In this space, we embrace play, spontaneity, and joy.”

2. The Science of Laughter & the Vagus Nerve (2 minutes) – Awareness

• Why laughter matters:
• Stimulates the vagus nerve, promoting a calm and connected state.
• Releases endorphins (feel-good hormones), reducing stress and tension.
• Enhances social bonding, making actors more present and engaged.

3. Vocalised Laughter Warm-Up (5 minutes) – Fake it ‘til You Make it

Even if laughter feels forced at first, the body doesn’t know the difference—it still activates the vagus nerve!

Step 1: "Ha Ha Ha" Exercise

• Inhale deeply, and on the exhale, say “Ha Ha Ha” in a rhythmic, exaggerated way.
• Start slow and gradually increase speed and volume.
• Repeat 5 rounds.

Step 2: "Ho Ho Ho" Exercise

• Take a deep breath in, and exhale with a low-pitched "Ho Ho Ho" (Santa Claus style!).
• Feel the vibrations in your diaphragm and throat, activating the vagus nerve.
• Repeat 5 rounds.

Step 3: "Hee Hee Hee" Exercise

• Now, take a deep breath and exhale with a high-pitched "Hee Hee Hee", directing the vibration to your head and chest.
• Repeat 5 rounds.

Notice how these different pitches affect different parts of the body and nervous system!

4. Playful Laughter Exercises (7 minutes) – Spontaneity & Joy

Now that the body and voice are warmed up, we’ll use laughter as an improvisational tool.

Step 1: “Silent Laughter” (1 min)

• Open your mouth wide and laugh without making a sound.
• Let your breath and body movement express the laughter.
• Engage eye contact with a partner if possible!

Step 2: “Exaggerated Fake Laughter” (2 min)

• Force out laughter, making it as over-the-top as possible.
• Notice how it transitions into genuine laughter.
• Let your body move with the laughter—clap your hands, hold your belly, stomp your feet!

Step 3: “Laughter Chain Reaction” (3 min)

• Stand in a circle (or imagine one if solo).
• One person starts with a small giggle, the next person builds it slightly louder, and so on until it turns into full-blown contagious laughter.
• Feel how laughter spreads and connects the group.

Step 4: “Vowel Laughter” (1 min)

• Laugh using different vowel sounds to explore vocal range and release tension:
• “Aah-ha-ha-ha-ha” (chest-focused)
• “Eeh-hee-hee-hee” (head-focused)
• “Ooh-hoo-hoo-hoo” (belly-focused)

5. Cool Down & Integration (4 minutes) – Resetting the Nervous System

• Return to deep breathing:
• Inhale for 4, hold for 4, exhale for 8. Repeat 3 times.
• Place a hand on your heart and feel the aftereffects of laughter.
• Gentle neck and shoulder rolls to release any remaining tension.
• Reflect silently:

"How does my body feel now compared to before?"
"What emotions or sensations have shifted?"

Why This Works for Actors

• Laughter loosens the body and breath, reducing tension before performing.
• It stimulates creativity and play, essential for spontaneity in acting.
• Activating the vagus nerve improves emotional resilience, making it easier to transition in and out of roles.

This session can be adapted for different energy levels—want a high-energy warm-up? Extend the laughter exercises! Need a calmer approach? Focus on breath and sound vibrations.

How the Vagus Nerve Controls Our Feelings

1. Regulates Stress & Relaxation
• The vagus nerve activates the parasympathetic nervous system (PNS), which is responsible for calming the body after stress.
• A well-functioning vagus nerve helps lower heart rate, blood pressure, and cortisol (the stress hormone), making it easier to feel relaxed and safe.
2. Influences Emotional Connection & Safety
• It helps regulate facial expressions, vocal tone, and social engagement, allowing us to connect with others.
• A healthy vagus nerve enhances feelings of trust, empathy, and emotional resilience.
3. Affects Anxiety & Depression
• If the vagus nerve is underactive, it can lead to higher levels of stress, anxiety, and depression.
• If it is stimulated regularly, it promotes emotional balance, reducing fear responses and increasing positive emotions.
4. Controls the Gut-Brain Connection
• The vagus nerve connects the brain and gut, influencing digestion and emotional states.
• Ever felt “butterflies” in your stomach or lost your appetite due to stress? That’s your vagus nerve in action!

How to Stimulate the Vagus Nerve for Emotional Regulation

1. Deep Breathing (Extended Exhales)

• Inhale for 4 counts, hold for 6, exhale for 8.
• Slow exhales activate the vagus nerve, shifting the body into a calm state.

2. Humming & Chanting

• Humming, chanting "OM," or singing creates vibrations in the throat, which directly stimulate the vagus nerve.

3. Cold Exposure

• Splashing cold water on your face or taking cold showers can increase vagus nerve activity, reducing stress responses.

4. Gentle Touch & Self-Soothing

• Placing a hand on your heart or belly while breathing deeply signals safety to the nervous system.

5. Meditation & Mindfulness

• Guided meditation and mindfulness help increase vagal tone, reducing reactivity to stress.

6. Social Connection & Laughter

• Laughing, making eye contact, and social bonding stimulate the vagus nerve, improving emotional resilience.

Why It Matters for Actors

Actors navigate intense emotions in performance. A strong vagus nerve helps manage stress, stay grounded, and recover from emotional scenes. Regular breathwork, vocal exercises, and mindfulness can train the vagus nerve to handle pressure and deepen emotional availability in performance.
