Fighting Cancer While You Sleep? The Untold Power of Natural Killer Cells

In this episode of Vitality Made Simple, join me, Dr. Debbie Ozment, as I shine a spotlight on one of the immune system’s most fascinating and underappreciated warriors: natural killer cells. She explains how these powerful lymphocytes act as the body’s rapid response team, targeting cancerous and infected cells without needing prior exposure. I break down the difference between the innate and adaptive immune systems and show why natural killer cells are crucial in unpredictable, ever-changing environments filled with new pathogens. This episode is packed with encouraging, actionable strategies to boost natural killer cell performance—from prioritizing sleep and engaging in the right levels of exercise, to optimizing vitamin levels, nourishing your gut with fermented foods, managing stress with intentional unwind time, and cultivating spiritual and social connections. I also discuss the immune-suppressing impact of things like processed sugar, seed oils, and loneliness. My message is simple and empowering: you don’t need fancy tools or expensive therapies to build a resilient immune system—just a few consistent, doable lifestyle choices that honor your body’s natural intelligence.
