Immunologist Dr. Jenna Macciocchi emphasizes the importance of social interaction for a longer, healthier life. Contrary to expensive anti-aging trends, she argues that strong social connections boost the immune system by releasing oxytocin, reducing inflammation, and improving overall well-being. Physical, in-person interaction is crucial for this effect, unlike online interactions. Dr. Macciocchi suggests focusing on social connection, joy, and stress reduction for immune system health throughout life, supplementing this with other lifestyle choices at different life stages.
