What is the Vagus Nerve and Why it Matters?
The vagus nerve, or the 10th cranial nerve, is one of the most important nerves in your body. It extends from your brainstem through your chest and abdomen, connecting to major organs like the heart, lungs, and gut.
Functions of the Vagus Nerve:
- Regulates digestion: Controls gut motility and enzyme secretion.
- Manages inflammation: Keeps your immune system balanced.
- Mood Regulation: Influences serotonin production, with 90% serotonin produced in the gut.
- Stress Recovery: Promotes relaxation after stressful events.
- Supports heart health: Regulates heart rate and blood pressure.
- Links gut and brain: Facilitates two-way communication in the gut-brain axis.
The vagus nerve is your body’s internal communicator, ensuring that your brain and body stay in harmony.
Signs of a Happy Vagus Nerve
A strong vagus nerve, known as good vagal tone, manifests as:
- Quick Recovery from Stress: Your heart rate slows quickly after deep breathing.
- Good Digestion: Regular, pain-free bowel movements and minimal bloating.
- Balanced Emotions: Resilience and calmness in daily life.
- Robust Immunity: Fewer illnesses and faster recovery times.
Signs of an Unhappy Vagus Nerve
Low vagal tone can lead to:
- Digestive Problems: Bloating, constipation, or diarrhea.
- Emotional Imbalances: Anxiety, depression, or irritability.
- Chronic Fatigue: Persistent tiredness and low energy.
- Weakened Immunity: Frequent illnesses or infections.
How to Self-Check Your Vagus Nerve Health
Step 1: Check Your Heart Rate Variability (HRV):
- Try the Welltory App Here
Step 2: Observe Your Digestion:
- Note patterns of bloating, constipation, diarrhea, indigestion, acid reflux
Step 3: Test Your Stress Recovery:
- Use the Welltory App and measure your heart rate.
- Now practice 7 minutes of slow, long, deep inhales and exhales
- Now measure your heart rate again. Have you noticed a considerable slowing down? If not, then your stress recovery is not good.
Step 4: Try the Cold Water Test:
- Use the Welltory App and measure your heart rate.
- Splash cold water on your face and over your head.
- Measure your heart rate again.
- A slowed heart rate indicates good stress recovery. Now significant reduction in heart rate indicates an unhappy vagus nerve.
