Every 40 seconds, someone in the United States experiences a heart attack. Every 34 seconds, someone dies from cardiovascular disease. In this powerful episode of The Science of Sound, Dr. Harris uncovers why nitric oxide may be one of the most important molecules in the human body — and how a deficiency could be silently impacting your heart, brain, blood pressure, energy levels, and even erectile function (ED).

Nitric oxide is far more than a gym supplement buzzword. It is a critical signaling molecule that relaxes and expands blood vessels, improves circulation, enhances oxygen delivery, supports immune defense, regulates inflammation, and plays a central role in memory and cognition. As we age, natural nitric oxide production declines — potentially contributing to hypertension, brain fog, cardiovascular disease, and metabolic dysfunction.

Dr. Harris explains why erectile dysfunction is often one of the earliest warning signs of nitric oxide deficiency, sometimes appearing years before more serious cardiac events. The conversation also explores the surprising impact of antibacterial mouthwash, fluoride, proton pump inhibitors (PPIs), and low stomach acid on nitric oxide production — and how long-term use of certain medications has been associated with increased risk of heart attack and Alzheimer’s disease.

This episode connects heart health, brain health, circulation, inflammation, and performance into one foundational concept. If you care about longevity, cardiovascular resilience, cognitive clarity, or understanding the deeper root causes behind ED and blood pressure issues, this conversation is essential listening.
