Aliquot #145: How to Protect Immune Function With Age
As we age, the immune system slows, loses precision, and low-grade inflammation rises. These changes increase infection risk, weaken vaccine responses, and reduce early cancer surveillance. Yet immune aging is not fixed. Movement, sleep, stress regulation, temperature exposure, and nutrition shape immune cell balance and inflammatory activity over time. In this Aliquot, together with Drs. Michael Snyder and Matt Walker, I explore age-related immune changes and examine behaviors that support immune resilience.
