Cortisol, the body's ancient alarm signal, was never designed for the sustained demands of contemporary schedules, and its chronic elevation quietly erodes the very capacities we need to meet those demands. What this expert offers is not a cure but a rhythm — small, repeatable choices woven into ordinary days that keep the body's stress system from tipping into chronic harm.
