An Invitation
Health, reimagined.
Dr. Alan Rozanski is an internationally recognized cardiologist, researcher, and educator whose work has focused on one fundamental question: What allows people not merely to survive, but to truly flourish?
For more than four decades, he has explored the science of health, vitality, resilience, and human flourishing. This search led to the development of the Six Domains of Health and Vitality—a new framework for understanding what creates lifelong health, energy, and well-being.
Explore the ideas, science, and practical tools that can help you live with greater vitality and purpose.
What is Health, Really?
The absence of disease
is not the presence of health.
If you are not depressed, does that mean you are happy?
Of course not. The absence of depression does not automatically create happiness, fulfillment, or joy.
Yet when it comes to health, we often make the same mistake.
Modern medicine has become extraordinarily good at identifying disease. But knowing what causes illness is not the same as understanding what creates health.
Without a clear understanding of health, we may inadvertently settle for far less than we are capable of becoming. We may overlook opportunities to build greater energy, resilience, purpose, emotional well-being, and engagement in life—not because disease is present, but because we have never been taught what positive health truly looks like.
For decades, my work has explored a fundamental question:
What allows people not merely to survive, but to truly flourish in good health?
The search for that answer ultimately led me in an unexpected direction.
The Heart of the Matter.
Vitality — the signal of health.
That unexpected direction was vitality.
Not vitality as a vague aspiration, but as something concrete and measurable — the feeling of being fully alive, energetic, engaged, and present in your life. Vitality is what flourishing actually feels like from the inside.
What I came to believe, after decades of research, is this:
Vitality may be one of the clearest signals of true health.
When vitality is present, something important is going right. When it is absent — when life feels flat, effortful, or diminished — something important is being missed, even in the absence of diagnosable disease.
This reframing matters, because it shifts the central question of health from What is wrong with me? to What would allow me to truly thrive? Those are very different questions, and they lead to very different answers.
The Framework
The Six Domains of
Health and Vitality
This raised a practical question: what actually produces vitality?
After years of research, a clear pattern emerged. The factors that most powerfully shape our health, longevity, and sense of vitality tend to cluster into six interconnected domains:
Physical Health
Emotional Mastery
Purposeful Living
Mental Vitality
Social Connectivity
Stress Management
What surprised me, again and again, was that these domains all seemed to influence the same outcome. Whether we strengthen the body, sharpen the mind, deepen our relationships, or find greater purpose, the result is often the same: greater vitality.
Understanding these domains — and learning to recognize how they are operating in your own life — is the foundation of everything explored on this site.
