Devices to Stimulate the Vagus Nerve There are two types of devices that stimulate the vagus nerve. Invasive Cervical Vagus Nerve Stimulation Invasive vagus nerve stimulation (VNS) is a medical procedure involving the implantation of a small device, similar to a pacemaker, under the skin of the chest. This device is connected to the cervical (neck) portion of the vagus nerve via thin wires. It sends electrical pulses to the nerve, which then carries signals to the brain and other parts of the body. These pulses help regulate the nervous system. VNS has been approved to aid in stroke recovery and treat obesity, depression, and epilepsy. However, it requires surgery, is expensive, and can have side effects, such as neck pain, coughing, difficulty swallowing, headaches, hoarseness, and a sore throat. Noninvasive Transcutaneous VNS Transcutaneous VNS (tVNS) is a noninvasive alternative that is more affordable and easy to use. A wearable device stimulates the vagus nerve through the skin near the ear, triggering reflexes without the need for surgery or implantation. This treatment can activate or calm areas of the brain involved in emotions and automatic body functions, making it useful for treating depression, heart failure, pain, inflammation, and headaches. One wearable device, the Sensate, gently stimulates the vagus nerve through sound and vibration therapy. Worn on the chest, the device emits low-frequency vibrations that resonate through the body, activating the vagus nerve pathways. These vibrations are often paired with soothing sounds via an app to create a multisensory experience. “Wearable devices are especially beneficial for clients who might find it challenging to achieve relaxation through breathwork alone or prefer a more tactile approach,” Jodi Duval, an Australian-based naturopathic physician with more than 15 years of experience and owner of Revital Health, told The Epoch Times.

How to Activate the Body’s Built-In Antidepressant One nerve controls stress, mood, and emotion. Most people have never even heard of it. But when you activate it, everything can change. Here’s how it works… 🧵 THREAD
