Light Shapes Your Biology: Sleep, Energy & Aging | Sarah Turner
Description
Sarah Turner is the founder and CEO of Sarah Thrive, where she explores a question most people rarely think about: how light shapes human biology. Her work focuses on circadian rhythms, mitochondrial health, brain function, and the role light plays in energy, sleep, recovery, and aging.
Beyond the science, Sarah challenges a deeper assumption — that decline is inevitable. This is a conversation about health agency and what happens when we start seeing light not just as something we live under, but as information the body runs on.
In this insightful conversation, Sarah shares:
• Who she was in her 20s and what she was trying to understand about health
• What she misunderstood about stress, energy, and feeling well
• Why light is a primary biological signal
• How modern indoor living and screens disrupt our biology
• Simple, practical steps for better sleep, energy, and recovery
• Why your 20s set the foundation for lifelong health
If you’re in your 20s staying up late, living indoors, or wondering why you feel drained, this episode offers clear science and practical tools you can start using today.
