The Best Vagus Nerve Stimulators: These Devices Tame Stress in as Little as 2 Minutes

Ever feel so stressed you’re equal parts wired and tired? Busy, modern life means many of us live stuck in a “fight or flight” state, even when we’re safe. Luckily, it’s possible to get back into relaxation mode. Scientists have discovered how to flip your nervous system’s off switch in minutes using devices that stimulate your vagus nerve—a giant nerve that runs through the body and communicates with your vital organs. I tested two of the best vagus nerve stimulators on the market that can help you shift from stressed to serene, fast. Here’s what I learned.

What is the vagus nerve—and why is everyone talking about it?

Let’s understand what makes this nerve so powerful, and why it’s become the wellness world’s hottest topic. The vagus nerve has been called the nervous system’s communication superhighway. It is the body’s largest continuous nerve that runs from the brain to the gut. And because it connects to so many organs, it helps influence everything including our mood, heart rate, sleep quality, mental focus and digestion.

In the past, activating the vagus nerve to switch on your calming parasympathetic nervous system required powerful prescription treatments or even surgical brain implants to send electrical signals to the nerve. But now, breakthrough technology has made it possible to activate this powerful nerve safely at home—no doctor’s visit required. Simply put: Vagus nerve stimulation (VNS) is the future of stress relief.

Best vagus nerve stimulators to try at home

Here’s what I discovered in my research, and how these two vagus nerve stimulation devices might help you finally feel calm and rested. Get ready to shift into a more relaxed state of living.

Tool #1: Nuropod vagus nerve stimulator—wearable stress relief

How and where it works: This vagus nerve stimulator device attaches to the ear, more specifically the triangular nub of cartilage in front of the ear canal called the tragus. It uses bioelectrical signals (a gentle buzzing) to target and stimulate the auricular branch of the vagus nerve.

Treatment time: Users can start with 15 minutes a day and slowly build up to 1 hour a day.

Stimulation levels: You can dial up the intensity on a scale from 1 to 45.

Popular uses: People use it to relieve work stress and improve cognitive performance, as well as help ease symptoms from chronic conditions such as long COVID, fibromyalgia and hypertension, just to name a few.

Research highlights: With a decade of research and more than 60 scientific studies—including work with Harvard and UCLA—the tragus route of vagus stimulation is backed by loads of research. Studies on this type of stimulation have found impressive results, including:

• 61 percent improvement in vagus nerve activity
• 78 percent reduction in inflammation markers
• 48 percent less fatigue
• 45 percent reduction in depressive symptoms
• 31 percent better sleep quality
• 18 percent improvement in heart rate variability (HRV)—a key measure of stress resilience
• 35 percent fewer anxious thoughts
• 32 percent better memory performance

Even more impressive: People with chronic conditions saw dramatic relief, with 85 percent fewer heart palpitations, 80 percent reduction in digestive symptoms and 61 percent improvement in post-viral symptoms like long COVID.

My results: When I tested it, I could feel myself shift into a relaxed state. And my heart rate variability improved from 32 to 49 within days. That represents a meaningful health upgrade.

Elisabetta Burchi, MD, head of research at Parasym (Nuropod’s creator), is such a believer that she uses the device herself in two ways. She told me she wears it when she wants to relax and also when she’s working and needs to harness her mental concentration. The fact that it’s handsfree and wearable makes it easy to use while multitasking.

The Price: $900, available at Nuropod.com. Look for promotional offers—some users report finding $100-off coupons online.

Tool #2: Truvaga Plus vagus nerve stimulator—fast relief in seconds

How and where it works: This handheld device stimulates the vagus nerve through the neck, specifically the transcutaneous cervical vagus pathway. You press and hold the vagus nerve stimulator against your pulse point. The company explains, “Truvaga’s patented energy signals penetrate the skin and underlying soft tissues to reach the vagus nerve directly, only 1.5 cm beneath the skin.”

Treatment time: It just takes two minutes a day to feel the benefits.

Stimulation levels: You can dial up the intensity on a scale from 1 to 10.

Popular uses: People use it for biohacking and longevity, as well as to fall asleep faster, stay asleep longer and wake up feeling more energized.

Research highlights: In studies, this tool successfully stimulated the vagus nerve in 90 percent of users. Scientific reviews have found statistically significant improvements in quality of life. And in a 2017 study, this type of stimulation improved stress markers and reduced inflammatory markers within 24 hours.

• Boosts mood and focus: In one study at a U.S. Department of Defense language school, career linguists who used the device showed accelerated recall in as little as two days.
• Improves memory: After two months of treatment, people using the device showed a 91 percent improvement in the ability to remember facts, stories and information.

My results: The moment I placed the Truvaga Plus against my neck and turned it on, I felt a gentle tingling sensation spread through my body. Within the two-minute session, a wave of relaxation washed over me. It was like my nervous system had been given permission to calm down. The subtle shift was immediate and noticeable.

Navaz Habib, a functional medicine practitioner known as the “Vagus Nerve Doc” and author of Upgrade Your Vagus Nerve, is impressed by the research behind Truvaga. “ElectroCore, the creators of Truvaga, has been at the forefront of vagus nerve stimulation research for over 20 years,” he explains. He’s particularly excited about this tool’s potential for women dealing with Sjögren’s disease and cluster headaches.

The price: $499, available at Truvaga.com.

Are vagus nerve stimulators worth the investment?

“A vagus nerve stimulator can stimulate changes that influence the communications between the brain and several major organs, which are all involved in controlling a person’s stress,” confirms Blen Tesfu, MD, a medical advisor at Welzo. “Users may experience some initial improvements in their ability to regulate stress responses, improve sleep quality, relax and feel better about themselves after using stimulation devices regularly for at least three to four weeks.” But she cautions that it may not work for everyone, since stress is complicated and has many factors.

Bottom Line: There are health benefits to improving your vagus nerve through stimulation. If you’re struggling with chronic stress, poor sleep or feeling constantly on edge, a vagus nerve stimulator might be the missing piece in your wellness puzzle.
