The Science of Cycles: Why Humans Are Wired for Rhythm

This month on Rise, we’ve been exploring cycles — in nature, in our work, in our bodies, and in our lives. In this episode, Dr. Inma takes us deeper into the science behind those rhythms.Drawing from ecology, psychology, and neuroscience, she explores why cycles are not just metaphors but fundamental biological patterns that shape how humans function. Ecosystems move through phases of growth, conservation, release, and renewal — and humans follow similar rhythms in our careers, identities, creativity, and emotional lives.You’ll hear about the biology of circadian rhythms, the brain’s 90-minute focus cycles, and the neuroscience behind the post-achievement dip that can follow major accomplishments. The episode also explores how emotions complete their own cycles, how experiences can echo across generations through learning and epigenetics, and why community plays a crucial role in resilience.Seasonal light patterns influence hormones, sleep, and mood, reminding us that even in modern life our bodies remain connected to the rhythms of the natural world. Ultimately, resilience isn’t about escaping change or maintaining constant productivity. It’s about recognizing the cycles we live within and learning to move with them.Because just like nature, life doesn’t move in straight lines — it moves in rhythms.Amabile, T. M., & Kramer, S. J.
