Dr. Michael Twyman shares how nitric oxide, light, sleep, and lifestyle protect the endothelium to prevent heart attacks and strokes.

Dr. Michael Twyman explains how heart attack and stroke prevention begins with protecting the endothelium and glycocalyx—the body’s vascular “force field.” He explores the role of nitric oxide, light, sleep, diet, and movement in optimizing vascular function, and highlights advanced tests and therapies that assess and restore arterial health. This episode offers practical, upstream strategies to reduce cardiovascular risk.
