🧩THE VAGUS NERVE!👂
Our ears are connected to the vagus nerve. Neurons in the brain vibrate at different frequencies based on the data they receive from our internal and external worlds, and these vibrations influence every cell throughout the body. When sound waves reach the brain, many different biological responses can be triggered, which have the power to alter our emotions, releases hormones, and put our minds and bodies into certain states
Sound therapy promotes physical and psychological healing by putting your body into the parasympathetic state. Also known as the ‘rest and digest’ part of the nervous system, it's the state in which our bodies naturally repair and heal; the opposite of ‘fight or flight.’ This state improves the immune system, lowers cortisol, lowers blood pressure, keeps you more alert during the day, and helps you sleep deeper at night.
The vagus nerve controls the parasympathetic nervous system and extends from the brain stem down to the colon and branches out to the heart, lungs, stomach and intestines. The vestibulocochlear nerve in the ear connects to the vagus nerve; a little branch of the vagus nerve goes right to the tympanic membrane, which vibrates in response to sound waves.
Every sound you hear sends information to the vagus nerve, which will either switch the parasympathetic nervous system on or off. In other words, the sounds you hear impact your hormone release, digestion, blood sugar levels, inflammation, heart rate, blood pressure, and more.
