The vagus nerve is a vital part of our body, connecting nearly every organ with the brain. It helps detect problems like a racing heart, stomach issues, and an overactive immune system. When it senses trouble, the vagus nerve calms us down, regulates blood pressure, and soothes stomach discomfort.
Some wellness influencers claim that stimulating the vagus nerve can cure various health issues, including long COVID, headaches, and memory problems. However, this hype is largely unfounded. Despite this, some research on the vagus nerve shows promise and has garnered scientific attention.
Scientific studies have confirmed that activating the vagus nerve with mild electrical pulses can treat certain conditions, such as epilepsy and depression. The US FDA has approved devices for these treatments, including a VNS device surgically implanted under the collarbone. Similar devices cleared in the US are also used to treat obesity, pain, and migraines.
External vagus stimulators, like earbuds or neckbands, have been cleared by regulatory bodies worldwide, including the US FDA, to help manage these conditions. While more research is needed, the science behind stimulating the vagus nerve is promising and worth exploring further.
