Athan Smyrlis MD

Dr. Athan Smyrlis, MD, FACC, is a board-certified cardiologist with a focus on preventive cardiology and lifestyle medicine. After years of treating patients during acute cardiac events, he became increasingly concerned with the patterns that quietly erode energy, sleep, clarity, and health long before a diagnosis appears.

In his clinical work, he repeatedly met people whose laboratory tests were “normal,” yet whose lives told a different story. They were exhausted, foggy, wired at night, and struggling to feel like themselves. That gap between measurable results and lived experience became the foundation for Why So Tired?

His approach emphasizes biological rhythm, optimal sleep, light exposure, and movement patterns as the foundational daily habits that support lasting vitality.

He was recently featured in the Long Island Herald for his work helping readers understand fatigue, poor sleep, brain fog, and the small daily habits that rebuild energy.

Dr. Smyrlis is also the founder of True Health Compass. He believes the future of medicine lies in helping people protect their health before disease takes hold.
