A Guide to Vagus Nerve Stimulation, the Secret to Making Travel Easier on Our Nervous Systems

Scroll far enough on social media, and you'll hit a quick fix promising to calm your nervous system in seconds. Mastering vagus nerve stimulation in particular has become wellness shorthand for “calm on demand,” but there's actual science behind how you do it properly—and it goes far beyond a 15-second clip.So, what is the vagus nerve? Essentially, the longest cranial nerve in the body, traveling from the brainstem down through the neck and chest into the abdomen, brushing past the heart, lungs, and gut. It's the main line of the parasympathetic nervous system—your body's primary mechanism for rest, digestion, repair—as opposed to the sympathetic system that gears you up to handle a threat. “If you think of your body as a car, the autonomic nervous system is the drivetrain and brakes,” says Lou Atkinson, clinical wellbeing lead of Yōjō, a health and wellness platform specializing in vagus nerve stimulation or VNS. “The sympathetic nervous system is the accelerator, while the vagus nerve is your essential braking system, slowing your heart rate, initiating digestion, and lowering inflammation.”Having a vagus nerve toolkit you can turn to when you need it most can make travel easier.

Leaving a familiar environment removes our daily safety anchors, and unresolved stress can resurface as anxiety or hypervigilance amid the unpredictability of new places. “Long after we’ve arrived, and the danger has passed, the body can keep replaying that same protective response—that’s why so many of us feel anxious or shut down for reasons we can't quite explain, especially when traveling,” trauma psychotherapist Emmy Brunner says. “Release isn't about forcing it—it happens through small, repeated doses of safety, not pushing through.”Travel can act as a stress-test for your autonomic nervous system.

"Splash cold water on the face—cold exposure activates the vagus nerve and can pull you out of a spiral almost instantly,” Brunner advises. Another tip she says is to: “Slowly look around the room and name a few things you can see—it reminds the nervous system it's present and safe."Another surprising method that works is quiet humming. “It stimulates the vagus nerve directly through the vocal cords,” says Atkinson. If you feel too conscious doing this in a public place, longer exhales also help engage it: "Breathe gently through your nose, inhale for four seconds, and exhale for six," says Rea. "Let the breath become quieter rather than bigger, and continue for two to five minutes."Perhaps the best advice is to think of nervous system work as part of your pre-travel prep, along with your packing and booking. “People often wait until they're deeply dysregulated to start regulating, but the earlier you start, the better,” Baldwin advises. She recommends getting outdoor light at both ends of the day to recalibrate your circadian rhythm before, during, and after your trip. As is having a piece of home with you. “Bringing something familiar, a candle, a journal, a photo, and orienting to a new room by consciously noticing its colors and sounds both help signal safety, too,” she adds.For frequent flyers wanting something more hands-off, wearable vagus nerve stimulators like yōjō deliver gentle electrical pulses to the ear's auricular branch, nudging the body into rest-digest mode without requiring meditation mid-flight—wearable while working, watching a film, or trying to sleep.Humming and splashing cold water on your face are two accessible ways to reset on your travels.

Our nervous systems need something called disconfirming experiences. “These are moments where we show, not tell, our nervous systems that the thing it thinks is dangerous is actually safe,” she says. After doing that, our nervous system has enough data points to see that the perceived danger is actually safe, and we no longer experience the anxiety we once did.None of this promises to make flying enjoyable—particularly if you struggle with it. But understood and practiced properly, vagal tone could be the deciding factor in whether a trip leaves you restored or wrung out. That’s worth knowing, next time you're stuck in seat 34C convincing yourself it's turbulence, when it’s actually your nervous system on overdrive.Emmy Brunner’s residential retreats combine hypnosis and somatic practice.
