How does the day you were born influence your health?

Beyond the familiar 24-hour circadian rhythm resides a lesser-known seven-day biological oscillation called the circaseptan rhythm. Research suggests that from birth onward, human physiology may follow weekly waves that influence immune regulation, inflammatory markers, vascular tone, and recovery patterns.

In this episode, we explore the science behind this rhythm and what it may mean for how we understand our own longitudinal health story.
