What if the way we live is completely out of sync with how we’re actually designed to function? We’re talking about our internal clocks—our circadian rhythms—and how they impact everything from our sleep and energy levels to our metabolism, mental health, and even longevity.

My guest today is Lynne Peeples, an award-winning science journalist and author of The Inner Clock: Living in Sync with Our Circadian Rhythms. She’s written for Nature, Scientific American, The Atlantic, and TIME, covering the science behind how our bodies interact with the environment. Her latest work dives deep into how modern life—artificial light, late-night screens, irregular eating patterns—is throwing off our biological rhythms and what we can do to fix it.

In this conversation, we’ll break down what’s happening inside our bodies on a 24-hour cycle, why so many of us are struggling with sleep and energy, and how small changes—like when we eat or when we get sunlight—can completely shift our health.
