Stimulate Your Vagus Nerve: Six Simple Ways to Support IBS, Stress, and Inflammation
The vagus nerve doesn’t get much airtime in everyday conversation, but it should. Quietly running from your brainstem through your chest and into your abdomen, this nerve is the unsung hero of your parasympathetic nervous system—the one responsible for calming you down, digesting your food, and generally keeping you alive in the least dramatic way possible.
For people living with Irritable Bowel Syndrome (IBS), stress-related inflammation, or just the modern grind of anxiety and burnout, learning to activate the vagus nerve may be a game-changer. Luckily, it doesn’t require a prescription or expensive equipment. With a handful of simple practices, you can stimulate this neural superhighway and help your nervous system return to balance.
1. Deep, Slow Breathing
Start with your breath. Slow, diaphragmatic breathing—where your belly, not your chest, does the rising—is one of the most effective ways to stimulate the vagus nerve and shift your body into parasympathetic mode.
Try this: Inhale through your nose for 4 to 6 seconds. Exhale slowly through your mouth for 6 to 8 seconds. Do this for 5-10 minutes a day. Even better, make it part of your IBS management routine, as explained in our guide on mindful movement and vigorous exercise.
2. Cold Exposure
No need to plunge into Arctic waters. Even modest cold exposure—ending your shower with 30 seconds of cold water or splashing cold water on your face—can stimulate the vagus nerve. Research shows this activates the dive reflex, a parasympathetic response that lowers heart rate and inflammation [PubMed].
Start small and build your tolerance. The cold does more than wake you up—it tunes your nervous system.
3. Vocal Vibration: Sing, Hum, or Gargle
Because the vagus nerve runs through your vocal cords, activities that stimulate the throat—like singing, humming, chanting, or gargling—can indirectly engage it. These small, often joyful practices produce vibrations that nudge your parasympathetic system into action.
A 2023 pilot study titled “Humming (Simple Bhramari Pranayama) as a Stress Buster” found that humming significantly increased heart rate variability (HRV) markers like SDNN and total power—strong indicators of vagus nerve activation. These findings support the notion that vocal vibration can effectively stimulate the parasympathetic nervous system, thereby reducing stress and enhancing resilience.
4. Yoga and Meditation
Yoga combines breath control, gentle movement, and mindfulness—three key components that support the activation of the vagus nerve. Practices like twisting poses, forward folds, and deep belly engagement can also support digestion, making them doubly beneficial for IBS sufferers.
Research published in Frontiers in Human Neuroscience supports this approach. A 2018 paper titled “Breath of Life” outlines how slow, rhythmic breathing—such as that used in meditation, humming, or yoga—activates the vagus nerve and increases vagal tone. This, in turn, reduces stress, promotes relaxation, and supports overall autonomic balance.
5. Rhythmic Aerobic Exercise (Yes, Running Counts)
Steady-state activities, such as long-distance running, swimming, or cycling, engage the vagus nerve through rhythmic breathing and movement. These workouts increase vagal tone and improve cardiovascular coherence.
Research has shown that increased vagal tone, as reflected by higher heart rate variability (HRV), is associated with better stress management, emotional resilience, and improved digestive regulation. According to Harvard Health Publishing, HRV offers valuable insight into how well your parasympathetic nervous system is functioning, making it a helpful proxy for vagus nerve activity.

6. Social Connection and Laughter
Of all the ways to stimulate the vagus nerve, human connection might be the most underappreciated. Genuine social interaction—whether through conversation, laughter, or simple companionship—sends a clear signal to the nervous system: you’re safe here. This sense of emotional safety helps activate the parasympathetic nervous system, reducing stress and encouraging digestive balance.
Emerging research underscores the health impact of connection. According to a 2025 report from the World Health Organization, strong social bonds are linked to improved health outcomes and a significantly lower risk of premature death—a reminder that loneliness is not just a feeling, but a physiological burden.

If you’re managing IBS or other chronic health issues, investing in meaningful social contact isn’t just good for the soul—it’s evidence-based nervous system support.
Final Thoughts
Stimulating the vagus nerve is not some esoteric wellness trend—it’s neurobiology. Whether you’re managing a chronic digestive condition like IBS, struggling with anxiety, or simply trying to find equilibrium in a noisy world, these daily habits offer a low-cost, science-backed way to feel better from the inside out.
Over time, small rituals like deep breathing, cold showers, yoga, and social laughter can change the way your body responds to stress—and that can change everything.
