The Circadian Rhythm and Sleep with Jessa Gamble

The Heart and Bones Podcast

What if our daily struggles with energy and sleep aren't just personal problems, but a clash between modern life and ancient biological rhythms? Jessa Gamble she/her, an award-winning science writer and journalist, takes us into the world of circadian rhythms in this episode. Through her book The Siesta and the Midnight Sun, Jessa explores how deeply these rhythms are embedded in the fabric of all living organisms, influencing our alertness, health, and even emotional well-being.

Jessa discusses the profound impact of artificial light on our natural sleep cycles and how societal pressures further skew our body clocks. She advocates for realigning our lives with the natural cycles of light and darkness to not only improve sleep but also enhance our overall health.
