Long COVID, also known as post-acute sequelae of SARS-CoV-2 infection (PASC), has left many individuals grappling with lingering symptoms such as brain fog, fatigue, gastrointestinal disturbances, anxiety, and difficulty breathing. As researchers and healthcare professionals continue to explore effective treatments, one promising approach is the stimulation of the Vagus Nerve.

In this article, Dr. Doreen Lewis, a seasoned chiropractor at San Pedro North Chiropractic Center, discusses the significance of the Vagus Nerve in our health and how its stimulation may offer relief for Long COVID symptoms.

Understanding the Vagus Nerve

The Vagus Nerve is the longest and most complex cranial nerve, running from the brainstem to the abdomen. It plays a critical role in the parasympathetic nervous system, which is responsible for “rest and digest” functions. This nerve influences heart rate, digestion, immune response, and mood regulation, among many other bodily processes.

When the Vagus Nerve is functioning optimally, it helps keep inflammation in check and supports the body’s ability to manage stress. However, disruptions to its function—whether from illness, chronic stress, or other factors—can lead to a range of health issues.

The Vagus Nerve and Long COVID

The ongoing symptoms of Long COVID are believed to be, in part, a result of persistent inflammation and an overactive sympathetic (fight-or-flight) response. Stimulating the Vagus Nerve can help balance the autonomic nervous system, reduce inflammation, and promote healing, offering hope to those with Long COVID.

Methods to Stimulate the Vagus Nerve

There are several ways to activate the Vagus Nerve and potentially alleviate symptoms associated with Long COVID. Here are some of the most effective methods:

1. Deep Breathing Exercises

• How It Works: Slow, deep breathing activates the Vagus Nerve, encouraging a parasympathetic response.
• Technique: Practice diaphragmatic breathing by inhaling deeply through your nose for four counts, holding for four counts, and exhaling slowly for six to eight counts. Repeat for several minutes.
• Benefit: Deep breathing lowers heart rate, reduces stress hormones, and enhances relaxation.

2. Cold Water Exposure

• How It Works: Exposing your face or body to cold water can trigger the “diving reflex,” which stimulates the Vagus Nerve.
• Technique: Splash cold water on your face or take a cold shower for a brief period. Alternatively, try immersing your face in a bowl of cold water.
• Benefit: This practice may lower inflammation and reduce symptoms like brain fog and fatigue.

3. Singing, Humming, and Chanting

• How It Works: The Vagus Nerve passes through the vocal cords and is stimulated by vocal activities.
• Technique: Singing your favorite songs, humming, or practicing chanting exercises such as “Om” can be beneficial.
• Benefit: These activities can help reduce anxiety and improve mood.

4. Gargling

• How It Works: Gargling engages the muscles at the back of the throat, stimulating the Vagus Nerve.
• Technique: Gargle with warm water for 30 to 60 seconds several times a day.
• Benefit: Gargling may boost immune function and improve symptoms like a sore throat or difficulty swallowing.

5. Acupuncture and Chiropractic Care

• How It Works: Acupuncture and chiropractic adjustments can help regulate the nervous system and promote Vagal Tone (the activity of the Vagus Nerve).
• Technique: Chiropractors, like Dr. Doreen Lewis, use specific adjustments to support nerve health, while acupuncturists may target points that activate the Vagus Nerve.
• Benefit: These therapies may alleviate pain, reduce inflammation, and support the body’s healing process.

6. Meditation and Mindfulness

• How It Works: Meditation practices that emphasize mindfulness and relaxation can enhance Vagal Tone.
• Technique: Try guided meditation apps or spend 10-20 minutes each day focusing on your breath and letting go of stress.
• Benefit: Meditation helps balance the nervous system, improve sleep, and reduce anxiety.

7. Yoga and Tai Chi

• How It Works: Both yoga and Tai Chi involve slow, deliberate movements combined with breathwork, stimulating the Vagus Nerve.
• Technique: Incorporate yoga postures or Tai Chi routines into your weekly exercise regimen.
• Benefit: These practices enhance overall well-being, increase flexibility, and reduce stress.

8. Gut Health and Nutrition

• How It Works: A healthy gut microbiome is essential for proper Vagal function.
• Technique: Consume a diet rich in fiber, probiotics, and anti-inflammatory foods. Avoid processed foods and sugars, which can disrupt gut health.
• Benefit: Improved gut health can lead to reduced inflammation and better mental and physical health.

9. Laughter and Social Connection

• How It Works: Laughing and spending time with loved ones can activate the Vagus Nerve.
• Technique: Engage in activities that make you laugh or participate in social events to strengthen your support system.
• Benefit: Laughter and connection reduce stress, boost immune function, and elevate mood.

Comprehensive Q&A Section

Q: What is Long COVID, and how does it affect the body?

• A: Long COVID refers to a range of symptoms that continue for weeks or months after the initial COVID-19 infection. Common symptoms include fatigue, brain fog, heart palpitations, shortness of breath, and joint pain. It is thought to be caused by lingering inflammation, immune dysregulation, and nervous system imbalances.

Q: How does the Vagus Nerve influence inflammation?

• A: The Vagus Nerve has anti-inflammatory effects. It releases neurotransmitters like acetylcholine, which help reduce the production of pro-inflammatory cytokines. By stimulating the Vagus Nerve, you can help modulate the body’s inflammatory response.

Q: Is Vagus Nerve stimulation safe for everyone?

• A: Most non-invasive techniques, like deep breathing, cold water exposure, and meditation, are safe for the general population. However, if you have specific health conditions or concerns, consult a healthcare professional before trying new stimulation methods.

Q: How can chiropractic care support Vagus Nerve function?

• A: Chiropractic adjustments, especially those targeting the upper cervical spine, can enhance nervous system function, including the Vagus Nerve. By ensuring proper alignment, chiropractic care may help alleviate symptoms of Long COVID and improve overall well-being.

Q: Can Vagus Nerve stimulation cure Long COVID?

• A: While there is no definitive cure for Long COVID, Vagus Nerve stimulation is a supportive therapy that can help alleviate symptoms. It works best as part of a comprehensive treatment plan that may include lifestyle changes, nutrition, and professional medical care.

Q: How long does it take to see results from Vagus Nerve stimulation?

• A: Results can vary. Some individuals may notice improvements in symptoms like anxiety or fatigue within days, while others may require weeks or months of consistent practice to experience significant benefits.

Q: Are there any risks associated with Vagus Nerve stimulation?

• A: Non-invasive techniques are generally low-risk. However, techniques like cold water exposure should be approached cautiously, especially for individuals with heart conditions. Always listen to your body and seek medical advice if you experience any adverse reactions.

Conclusion

The Vagus Nerve is a powerful ally in the journey to recovery from Long COVID. By incorporating simple yet effective techniques to stimulate this nerve, you can support your body’s healing processes, reduce inflammation, and improve your quality of life.
