First responders—like police officers, firefighters, and emergency medical workers—face a lot of stress every day. They deal with dangerous situations and make quick decisions to keep others safe. But how can they take care of their own mental and physical health? One answer may surprise you: the vagus nerve. In this blog post, we’ll explore what the vagus nerve is, why it matters for first responder wellness, and simple ways to use this knowledge to manage stress.

What is the Vagus Nerve?

The vagus nerve is the longest cranial nerve in the body. It runs from the base of the brain, all the way down the spine, and touches almost every organ, including the heart, lungs, and digestive system. According to licensed social worker Jamilyn DeSanti, who appeared on the “When The Call Hits Home” podcast, “that vagus nerve… touches every single organ in our body. When that gets activated, what happens is… it’s not just the emotions that we feel. It’s the physical response to it.”

In other words, the vagus nerve helps control how our bodies react to stress. It can make hearts race when you’re in danger, or slow things down when you need to relax.

The Vagus Nerve and First Responder Stress

First responders are often in “fight or flight” mode. Their bodies and brains are ready to handle emergencies, but this constant high-alert state can wear anyone down. As Ashlee explained, “a lot of first responders just never calm down. They don’t know how to be calm.”

So, how does the vagus nerve fit in? If first responders learn how to recognize and activate their vagus nerve, they can help their bodies return to a calmer state after stress. This isn’t just about feeling better emotionally—it can also help prevent long-term health problems like high blood pressure, digestive issues, and trouble sleeping.

Simple Ways to Activate the Vagus Nerve

You don’t need special equipment or hours of free time to take care of the vagus nerve. Here are some simple techniques you can start using today:

1. Deep Breathing

Deep breathing is one of the fastest ways to tell your body it’s safe. As Jamilyn DeSanti shared, “deep breathing… brings in that oxygen and resets literally the whole body. That activates [the vagus nerve], and it signals, ‘Hey, you are safe. You can be calm in that moment.’” Try slow, deep breaths in through your nose and out through your mouth.

2. Cold Water

Putting cold water on your hands, neck, or behind your ears can activate your vagus nerve. This quick “shock” to the system helps your body slow down and reset.

3. Sour Candy or Strong Tastes

Believe it or not, sucking on sour candy or tasting hot sauce (not confirmed) can also send signals through the vagus nerve to slow down intense reactions.

4. Laugh and Sing

Laughter and singing help activate the vagus nerve too. Watch a funny video, belt a favorite tune in the car, or share a laugh with friends.

How This Helps First Responder Wellness

Recognizing how your body feels during stress—and knowing a few tricks to calm down—can make a big difference. Not only does this help first responders handle emergencies better, but it also helps them be healthier and happier at home. As Jennifer put it, “you kinda have to know this about yourself. You have to pay attention to your body and have some insights there.”

First responders, try a few of these vagus nerve tips. You may find you sleep better, feel less irritable, and enjoy a better sense of well-being—on and off the job.
