Vagus Nerve Stimulation for Long COVID | Do HRV Exercises & Non-Invasive Treatment Work?

Key Takeaways

Vagus nerve stimulation (VNS) may be a promising method for managing long COVID symptoms.
VNS activates the parasympathetic nervous system and reduces inflammation.
HRV (Heart Rate Variability) exercises like deep breathing and cold showers can complement VNS.
Non-invasive VNS devices like Pulsetto are an accessible and user-friendly way to stimulate the vagus nerve.
Using Pulsetto regularly can relieve stress, anxiety, and insomnia, contributing to the better management of long COVID.

Vagus Nerve Stimulation and Long COVID

Long COVID is a term used to describe the lingering symptoms that some individuals experience after they recover from the initial COVID-19 infection. These symptoms can include chronic fatigue, brain fog, headaches, and irregular blood pressure. The condition can significantly impact your quality of life.

How Vagus Nerve Stimulation Works

The vagus nerve is a critical part of our body's parasympathetic nervous system that regulates several essential functions, including heart rate, digestion, and immune response. By stimulating the vagus nerve, we activate the parasympathetic nervous system, which reduces inflammation and promotes a state of calm.

Vagus nerve stimulation (VNS) involves sending mild electrical impulses to the vagus nerve by various methods. This stimulation can improve your mood, reduce anxiety, and enhance your sense of well-being. For individuals with long COVID, VNS may be beneficial in addressing the neurological symptoms associated with the condition.

Benefits for Long COVID Patients

Patients with long COVID often struggle with debilitating symptoms that may persist for months. Vagus nerve stimulation offers several potential benefits including:

Reduced Fatigue: VNS can help alleviate chronic fatigue, one of the most common symptoms of long COVID.
Improved Cognitive Function: By reducing brain fog and enhancing mental clarity, VNS can help individuals regain their cognitive abilities.
Better Mood and Reduced Anxiety: VNS can promote a sense of calm, helping individuals manage their anxiety levels and improve their mood.

Regulated Blood Pressure: VNS can help stabilize blood pressure, reducing the risk of complications associated with long COVID.

Clinical Evidence and Studies

Several studies have tested the effectiveness of vagus nerve stimulation in managing long COVID symptoms. Early small-scale trials have shown promising results, with participants reporting reductions in chronic fatigue, headaches, and irregular blood pressure.

For example, a pilot study published in Frontiers in Neurology performed on 24 female participants found significant improvements in cognitive function, anxiety, depression, and sleep after a 10-day t-VNS intervention (30 min/session, twice a day).

A 2022 clinical trial designed for at-home use of t-VNS demonstrated that participants could safely and effectively self-administer the treatment. This trial suggested that t-VNS might lead to mild to moderate improvements in mental fatigue and other long COVID symptoms although the study was not large enough to draw definitive conclusions about efficacy.

These findings suggest that VNS could be a valuable tool in treating long COVID.

Using HRV Exercises for Long COVID

Heart Rate Variability (HRV) exercises are another effective way to manage long COVID symptoms. HRV refers to the time variation between each heartbeat, and a higher HRV score is associated with better health and resilience.

HRV exercises can help reduce stress, improve mood regulation, and enhance well-being. For example, deep breathing exercises can help calm the nervous system and reduce anxiety. Mindfulness meditation can help individuals stay present and focused, reducing the mental fog often associated with long COVID.

Examples of Effective HRV Exercises

Here are some effective HRV exercises that can be easily incorporated into your daily routine:

Deep Breathing: Sit comfortably and take a slow, deep breath in through your nose, allowing your abdomen to expand. Hold your breath for a few seconds, then slowly exhale through your mouth. Repeat this process for 5-10 minutes.
Mindfulness Meditation: Find a quiet space and sit comfortably. Close your eyes and focus on your breath, letting go of any distracting thoughts. Practice this for 10-15 minutes daily.
Cold Showers: Start with a warm shower and gradually lower the temperature until the water is cold. Stay under the cold water for 1-2 minutes, focusing on deep, steady breathing.

Cold showers can invigorate the body and improve circulation.

It’s also clinically tested and designed for daily use. Since it’s non-invasive and drug-free, there’s no risk of dependency or side effects. You can use it once a day or several times depending on your needs, before bed, during a stressful moment, or to reset between work tasks. It’s safe, simple, and built for consistency, so the more you use it, the better your nervous system functions over time.

Above all, Pulsetto devices have performed more than 1.5 million simulations already with zero side effects.

How fast will I feel results?

Most users feel noticeably calmer within just 4 minutes. That’s because Pulsetto uses clinically proven vagus nerve stimulation to rapidly shift your nervous system out of fight-or-flight mode and into rest-and-digest. Unlike supplements or meditation apps, there’s no need to wait weeks for subtle changes, relief starts almost immediately. Over time, regular use also strengthens your vagal tone, making you more resilient to stress and better able to stay calm throughout the day.

What does it feel like?

It feels pleasant! Most users describe it as a slight tingling sensation, or a tickle. It’s designed to relax you, so it’s completely pain-free — otherwise it wouldn’t be very calming, would it!

What exactly is the vagus nerve, and why does it matter?

The vagus nerve is the longest cranial nerve in your body, and it plays a crucial role in regulating your mood, stress, digestion, heart rate, and sleep. It’s like your body’s internal switchboard for calm and recovery. Pulsetto gently stimulates this nerve to activate the parasympathetic nervous system, helping you slow down, relax, and restore balance. It’s the same nerve doctors stimulate in clinical settings to treat mood and anxiety disorders, but Pulsetto brings this powerful science home.

Can Pulsetto help me sleep better?

Yes, Pulsetto helps you fall asleep faster, stay asleep longer, and wake up more refreshed. By stimulating your vagus nerve, it activates your parasympathetic nervous system (the one responsible for rest and recovery), helping your body power down naturally. It’s a non-invasive, drug-free solution that works with your body’s own biology. Whether you struggle with racing thoughts, trouble falling asleep, or restless nights, Pulsetto helps create the calm, balanced state your body needs to enter deep, restorative sleep.

What’s included in the Pulsetto App? Is it free?

Yes, the app is 100% free and comes included with the Pulsetto device. It offers 5 unlimited stimulation programs for sleep improvement, nervousness, stress reduction, burnout, and pain management.

The app works with both iOS and Android. It also has a specialized Sound Library filled with sounds specifically designed for Pulsetto, which improve the overall experience.

Do I need to be tech-savvy to use it?

Not at all. Pulsetto is designed to be incredibly easy to use. Just place it around your neck, open the free app, and start your session. The app walks you through everything, from choosing the type of session to adjusting intensity levels. Even if you're not into tech, you’ll find it intuitive and seamless. It’s as easy as putting on a pair of headphones and pressing play, except instead of sound, you're stimulating calm.

Can Pulsetto really help with stress and anxiety?

Yes, and that’s where Pulsetto truly shines. Chronic stress and anxiety are often caused by an overactive sympathetic nervous system (the fight-or-flight response). Pulsetto works by activating the opposite system, the parasympathetic, which signals to your body that it’s safe, helping you relax almost instantly. Whether you're managing daily overwhelm or deeper emotional stress, Pulsetto gives you a powerful tool to self-regulate in a natural, consistent way. It’s peace of mind at the push of a button.

How is Pulsetto different from other wellness tools like meditation apps or supplements?

Meditation apps and supplements can help, but they often take time, focus, and commitment. Pulsetto works physically, not just mentally. By directly stimulating the vagus nerve, it taps into your nervous system’s core functions, creating a fast and reliable physiological shift. You don’t need to “get in the zone” or wait weeks for effects. It’s consistent, clinically supported, and easy to use daily. Pulsetto is not just a wellness tool, it’s a nervous system upgrade.

What if I don’t struggle with anxiety or sleep, can Pulsetto still benefit me?

Yes! Even if you’re not actively struggling, Pulsetto can still improve your overall health and performance. Regular vagus nerve stimulation boosts focus, sharpens mental clarity, supports digestion, reduces inflammation, and even enhances athletic recovery. Think of it like exercise for your nervous system, the more you use it, the stronger and more balanced it becomes. Pulsetto is perfect for anyone who wants to feel more grounded, energized, and resilient in their everyday life.

Who is Pulsetto designed for?

Pulsetto is for anyone who feels overwhelmed, stressed, tired, anxious, or sleep-deprived, basically, most people today. It’s especially helpful for busy professionals, parents, high-performers, and anyone seeking a non-medicated, science-backed way to feel better.
