In her TED Talk, Kasley Killam argues that social health—the quality of our relationships—is just as vital as physical and mental health. She tells the story of “Maya,” a woman with a healthy lifestyle who still felt unwell due to a lack of connection. Killam reveals that loneliness affects 1 in 4 people globally and increases health risks as much as smoking or obesity.
She introduces the 5-3-1 rule: connect with 5 people weekly, nurture 3 close relationships, and spend 1 hour a day in meaningful connection. Through stories and science, Killam makes a compelling case that investing in our social lives is essential to happiness, resilience, and longevity.
Her vision? A world where social health is taught, prioritized, and practiced—like fitness for the soul.
