The hype surrounding the vagus nerve and its potential benefits is on the rise, with people turning to various techniques and devices to stimulate this nerve. The vagus nerve serves as a vital communication channel between the brain and organs, controlling involuntary processes like heart rate and digestion. Scientific interest in vagus nerve stimulation has grown, with studies exploring its potential as a treatment for obesity, depression, arthritis, and COVID-related fatigue. While some behaviors like breathing exercises and meditation may help activate the vagus nerve, experts caution that selectively stimulating the nerve through external devices may not be as effective. Further research is needed to determine the true clinical potential of vagus nerve stimulation.
