great nerve

Dr. Kevin Tracy

Your health and happiness depend on a bundle of 200,000 nerve fibers that hold the secrets of life itself.

The vagus nerve is often referred to as the “superhighway” that connects every organ in the body to the brain, and vice versa, but it's more than just traffic.

The "great nerve" vibrates in tune with your health like the instruments of an orchestra: When the vagus nerve is healthy, so are you. When it's not, you suffer from everything from poor sleep to low mood, pain and suffering, and chronic disease.

Recent scientific advances, including Dr. Kevin Tracy's research showing how the vagus nerve is linked to the immune system, have brought the nerve to the attention of everyone from neuroscientists to TikTok influencers.

In his book, "The Vagus Nerve," Dr. Tracy shares the science of how the vagus nerve works to regulate our health, how we can help it, and the truth behind popular "vagus nerve stimulation" strategies like ice baths, meditation, exercise, and breathing exercises.

Uncovers extraordinary new science that promises to revolutionize healthcare, as electronic chips may regulate blood sugar, and electrical implants may replace your medications forever.

The groundbreaking treatment of vagus nerve stimulation shows potential to reverse life-changing diseases such as rheumatoid arthritis, inflammatory bowel disease, lupus, multiple sclerosis, diabetes, obesity, stroke, depression, Alzheimer's, and Parkinson's disease. Vagus nerve not only revolutionizes how we understand and treat disease, but also offers unprecedented hope for our health.
