Episode description
- Developing strong, lifelong social bonds helps slow biological aging by influencing how your genes, immune system, and stress hormones function
- People with higher "cumulative social advantage," meaning consistent emotional support throughout life, show younger cellular profiles on aging clocks like GrimAge and DunedinPACE
- Those with rich social connections have lower levels of inflammatory markers such as interleukin-6 (IL-6) and C-reactive protein (CRP), reducing the risk of heart disease, diabetes, and neurodegeneration
- Social isolation not only accelerates aging but also contributes to nutrient deficiencies, with lonely older adults showing lower intake of magnesium, potassium, vitamins B6 and C, and folate
- Rebuilding connection, such as through community, shared meals, and meaningful daily interactions, restores biological balance, lowers inflammation, and supports longer, healthier living
