The Art and Science of Connection: Why Social Health Is the Missing Key to Living Longer, Healthier, and Happier

The Art and Science of Connection by Kasley Killam is a revolutionary guide to redefining what it truly means to be healthy, introducing the concept of social health—the vital aspect of well-being that comes from meaningful human connection.

Most health advice focuses on physical and mental wellness—exercise, diet, therapy—but Killam, a Harvard-trained social scientist, argues that this approach ignores a crucial third dimension: our relationships. Research shows that strong social ties not only make us happier but also significantly improve longevity and overall health. People with a deep sense of belonging are 2.6 times more likely to report excellent health, while those without social support are 53% more likely to die from any cause.

Killam proposes that, just like physical fitness, we can strengthen our “social muscles.” Drawing from cutting-edge science, real-world stories, and practical tools, she presents the first comprehensive framework for cultivating social health—a skill that can be developed and maintained throughout life.

In this inspiring and practical book, readers will:

• Learn to evaluate and improve their social health using a simple, evidence-based framework.

• Discover specific strategies and habits to build and sustain deep, meaningful relationships.

• Find examples of how connection can be nurtured across all environments—neighborhoods, workplaces, and even online.

• Explore innovative stories of doctors, entrepreneurs, and communities creating a more socially connected world.

• See how individuals at different life stages—a student, a newlywed, a professional, and a widow—found healing and growth through connection.

The Art and Science of Connection offers an antidote to the loneliness epidemic and redefines wellness as not only physical and mental, but also profoundly social. It’s a transformative, research-backed handbook for anyone—introverts and extroverts alike—who wants to live a healthier, more connected, and more fulfilling life.
