Did you know you actually have a chill-out button in your back pocket ? It’s called the vagus nerve . (And, yes, vagus nerve stimulation is a thing.) “The vagus nerve connects the brain to the body and its primary function is to activate our parasympathetic nervous system (PNS),” says Erin D’Elia Assenza , a certified health coach at Parsley Health . There are two branches of the nervous system, the PNS, “rest and digest” and sympathetic nervous system (SNS), or “fight and flight.”
Of course, it’s not literally located in your back pocket—the vagus nerve runs from the brainstem through the neck and down to your abdomen. Its main function is to regulate digestion and your heart and breathing rate. When it’s activated, it will temper your physiological stress response, allowing a feeling of calm to wash over you. And the good news? There are specific exercises you can do for vagus nerve stimulation.
It’s an impossible game to try to avoid stress . Since stress is ubiquitous, it’s how you react to it that counts the most when it comes to your wellbeing. So vagus nerve stimulation can be a tool you use during any moment you need to de-stress.
“Stimulating the vagus nerve tricks your brain into thinking that everything is okay,” says D’Elia Assenza. A great time to stimulate the vagus nerve, she says, is when you’re experiencing a heightened state of anxiety or stress. “When something feels out of your control, these exercises are something you can do that’s in your control,” says D’Elia Assenza. You can also practice vagus nerve exercises regularly to better build up your resilience against stress. “I believe we should prioritize our stress every day—even when we don’t feel like we’re stressed. It’s such a huge part of having optimal health,” she says.
Consider what happens when your sympathetic nervous system is keyed up —maybe you’re stuck in traffic, just received a nasty email, feel overwhelmed at your job, or had a fight with your partner or a friend. “When you’re in fight-or-flight mode, the job of the SNS is to promote survival. So, in the face of a threat, your body wants to make sure you can run for your life: Your heart rate increases, your pupils dilate, and other systems you don’t need at the moment are down-regulated. Meaning digestion, immune, and reproductive systems slow,” says D’Elia Assenza. When you employ exercises that tell your brain and body that all is well , you not only can tap into a better headspace, but your physical health benefits, too.
For example, the vagus nerve is a channel that receives signals from the gut microbiota and zips that info over to the brain, notes a 2018 paper in Frontiers in Neuroscience . The authors point out that stress inhibits the vagus nerve and may be linked to GI disorders like irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) through inflammation .
In essence, the vagus nerve plays an important role in the gut-brain axis , which affects your mood and has been implicated in the development of depression and anxiety . Another study , published in the same journal, noted that vagus nerve stimulation may be an additional therapy for treatment-resistant depression and posttraumatic stress disorder. (Of course, these exercises are not a substitute for treatment your provider has recommended for you.)
Doing vagus nerve exercises also increases your vagal tone, which D’Elia Assenza describes as your capacity to handle stress and determines how quickly you can bounce back from stressful events. “Think of it like exercise—you may stimulate your ab muscles by doing crunches to have greater muscle tone in your core,” she says.
There are so many ways you can stimulate the vagus nerve—and they can be fun, calming, or fit in with the day-to-day routines you already have in place. “The list of things you can do is extensive. You don’t have to do them all, you can choose the activities that you like and make you feel good,” D’Elia Assenza says.
She likes to break them up into two categories: physical and emotional vagus nerve stimulators and encourages clients to look at them as a toolbox. You can pick out the ones you need in the moment or that resonate with you at that time. Aim to get in five minutes a day, throughout the day of the below vagus nerve exercises.
These activities all center around one thing: Manipulating the vocal cord. “The physical reverberation of your vocal cords can activate the vagus nerve,” D’Elia Assenza explains.
Getting the vagus nerve moving isn’t the only way to stimulate the vagus nerve though—your thoughts and feelings can activate it, too. “Eliciting an emotional response that can be supportive to the vagus nerve and calming parasympathetic nervous system,” says D’Elia Assenza.
