As winter sets in, our immune systems are under new kinds of stress. In this special mashup, Jeff revisits three powerful conversations that explain how the immune system actually works — and how to support it through food, sunlight, sleep, and daily habits. Dr. Jeffrey Bland explores the immune system as a dynamic, adaptive network that’s constantly learning from how we live. Dr. William Li reveals how the microbiome communicates with immune cells and how the foods we eat shape that conversation. And Dr. Roger Seheult shares how vitamin D, rest, and gentle exposure to heat and cold can help the body build resilience and fend off infection. Think of it as your winter immunity playbook — practical, science-backed tools for staying strong this season.
