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. 

Non-Invasive Vagus Nerve Stimulation Devices for Long COVID Treatment

Non-invasive vagus nerve stimulation devices are a convenient and effective way to manage long COVID symptoms. These devices are designed to stimulate the vagus nerve without surgical implantation, making them accessible to a broader range of individuals.

Overview of Non-Invasive Devices

Non-invasive VNS devices typically use electrodes placed on the skin to deliver mild electrical impulses to the vagus nerve. These devices are user-friendly, can be used at home, and are a practical solution for those looking to manage their long COVID symptoms.

Benefits Over Traditional Methods

Non-invasive VNS devices offer several advantages over traditional implantable devices:

• Accessibility: Anyone can use non-invasive VNS devices. 
• Convenience: These devices are suitable for home use and make it easier to incorporate VNS into a daily routine.
• Cost-Effectiveness: Non-invasive devices are generally more affordable than implantable devices, making them a cost-effective option for many individuals.

How to Use Non-Invasive Devices

Most non-invasive VNS devices come with clear instructions on electrode placement and settings for optimal vagus nerve stimulation. Follow manufacturer guidelines for safe and effective use.

Here are some general steps to follow when using a non-invasive VNS device:

• Clean the area where the electrodes will be placed to ensure good contact.
• Apply the conducting gel. 
• Attach the electrodes according to manufacturer instructions.
• Turn on the device and adjust the settings to a comfortable level.
• Use the device for the recommended duration, typically 15-30 minutes per session.

Popular Non-Invasive Devices on the Market

Several non-invasive VNS devices are available on the market, each with unique features and benefits. One such device is Pulsetto, which has gained popularity for its effectiveness and user-friendly design.

Other popular non-invasive VNS devices include:

• gammaCore: A handheld device that delivers mild electrical impulses to the vagus nerve through the skin.
• Nurosym: A wearable device designed to stimulate the vagus nerve and improve HRV.

Pulsetto Vagus Nerve Stimulation

What is Pulsetto?

Pulsetto is a non-invasive VNS device designed to stimulate the vagus nerve non-invasively and provide quick stress relief and relaxation. It offers quick results, typically taking effect in as little as 4 minutes, and is highly praised for its adjustable settings, allowing users to tailor their relaxation experience.
