LET'S TALK VAGUS NERVE
There's a two way nerve that runs between your gut and your brain called the vagus nerve. It's a two-way form of communication.
The vagus nerve is part of your ANS (autonomic nervous system), this system is automatic in that you have little to no control over its functions.
The ANS has three branches:
1. Sympathetic nervous system - designed to keep you in flight & fight β a highly alert state that is damaging to your health if it doesnβt abate
2. Parasympathetic nervous system - controls rest and digest functions - the opposite of your fight or flight response and where you should aim to be most of the time. Think parachutes bring you down safely!
3. Enteric nervous system β ever heard the phrase your 'second brain', well this is it and it regulates your gut
The vagus nerve, also known as the vagal nerves,
are the main nerves of your parasympathetic nervous system. So weβll focus on that.
These nerves play important roles in several
body functions, including:
π Digestion
π Heart rate
π Blood pressure
π Mood
π Breathing
π Skin/muscle sensations
π Immune response
π Mucus and saliva production
π Speech
π Taste
π Urine output
When the vagus nerve is sluggish then you can find these symptoms creep up on you:
π₯ Abdominal pain
π₯ Bloating
π₯ Acid reflux
π₯ Fluctuations in heart rate, blood pressure or blood sugar
π₯ Difficulty swallowing or loss of gag reflex
π₯ Dizziness or fainting
π₯ Hoarseness, wheezing or loss of voice
Here's 5 things to help activate your vagus nerve:
βοΈ Deep breathing
βοΈ Splashing cold water on your face
βοΈ Loud singing
βοΈ Humming
βοΈ Gargling (or activating gag reflex)
It's a big topic, but this gives you a short insight.
