Inflammation and the Vagus Nerve

The vagus nerve is undeniably the most important nerve in terms of the gut-brain connection and gut bacteria. It is responsible for a range of functions related to the parasympathetic nervous system, which is responsible for the "rest and digest" response in the body.

The vagus nerve plays a critical role in regulating heart rate, breathing, and digestion, as well as controlling certain reflex actions such as coughing and sneezing. It also plays a role in regulating inflammation in the body and has been shown to be involved in the body's stress response.

In addition to its physiological functions, the vagus nerve has also been associated with a range of mental and emotional states, including feelings of calm and relaxation, social bonding, and even spirituality.

The vagus nerve plays an important role in regulating inflammation in the body.

When you're faced with a threat or infection, your immune system responds by triggering an inflammatory response, which is a necessary part of the healing process.

However, if inflammation is not properly regulated, it can become chronic and contribute to a range of health problems, including autoimmune disorders, cardiovascular disease, and even depression.

The vagus nerve helps to regulate inflammation by sending signals to the immune system and other organs in the body.

When the vagus nerve is activated, it reduces the production inflammatory cytokines, which are molecules that contribute to inflammation in the body.

Techniques such as deep breathing, meditation, and yoga, which are known to stimulate the vagus nerve, have been shown to have anti-inflammatory effects in the body. Similarly, vagus nerve stimulation (VNS) has been shown to be an effective treatment for conditions such as rheumatoid arthritis and inflammatory bowel disease, which are characterized by chronic inflammation.

Low Vagal Tone Keeps You Stuck in Stress

When your vagal tone is low, it means your vagus nerve isn't as resilient in handling the ups and downs of life. This can pave the way for a host of issues like digestive troubles, inflammation, anxiety, and yes, even depression.

Low vagal tone has been linked to a number of health conditions, including irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), chronic fatigue syndrome, and fibromyalgia.

Digestive issues: An overactive vagus nerve can lead to increased digestion and bowel movements, leading to symptoms such as bloating, abdominal pain, and diarrhea.
Dizziness or fainting: The vagus nerve can affect blood pressure and heart rate, and an overactive vagus nerve can lead to a sudden drop in blood pressure and dizziness or fainting.
Chronic fatigue: The vagus nerve is involved in regulating the body's energy levels, and an overactive vagus nerve can lead to feelings of exhaustion or chronic fatigue.
Respiratory issues: The vagus nerve is involved in regulating breathing, and an overactive vagus nerve can lead to symptoms such as shortness of breath or rapid breathing.
Anxiety and panic attacks: The vagus nerve is also involved in regulating the body's stress response, and an overactive vagus nerve can lead to increased anxiety or panic attacks.

How to Increase Your Vagal Tone

Boosting your vagal tone isn't something you can accomplish overnight. It takes dedication and consistent effort to see results. Here are some strategies to help increase your vagal tone:

Deep breathing: Slow, deep breathing is one of the most effective ways to stimulate the vagus nerve and increase vagal tone. Try taking slow, deep breaths, inhaling for 5-6 seconds and exhaling for 5-6 seconds.
Meditation: Regular meditation practice has been shown to increase vagal tone, reduce stress, and improve overall well-being. Check out my self healing guided meditations on the Kimiya Healing Podcast.
Yoga: Yoga postures, especially those that involve gentle backbends and chest opening, have been shown to stimulate the vagus nerve and increase vagal tone.
Social connection: Building strong social connections and relationships has been shown to increase vagal tone and improve overall health.
Cold exposure: Cold exposure, such as taking cold showers or immersing yourself in cold water, has been shown to increase vagal tone and reduce inflammation.
Exercise: Regular exercise, especially aerobic exercise, has been shown to increase vagal tone and improve overall health.
