Heart HealthYour Vagus Nerve Is a Medical Tool Cardiologists Have Used for Decades
The vagus nerve controls the body's parasympathetic "rest and digest" response, and cardiologists have long used techniques that activate it to slow dangerous rapid heart rhythms. Dr. Pradip Jamnadas, an interventional cardiologist, explains that the same mechanisms behind clinical tools like the Valsalva maneuver can be harnessed by everyday people to reduce stress, lower blood pressure, and improve nervous system balance. This isn't a wellness trend — it's established cardiovascular medicine being applied more broadly. For health-conscious adults, understanding vagal tone offers a low-cost, drug-free pathway to better autonomic regulation, which has downstream effects on heart health, inflammation, and overall longevity.
