Sleep impacts every aspect of our health—from athletic performance and recovery to hormone balance, cognitive function, and longevity. But one of the most overlooked factors affecting sleep quality may be something surprisingly simple: temperature.

In this episode of Marni On The Move, I speak with Dr. Nicole Moyen, Chief Science Officer at Eight Sleep, about the science behind better sleep and how temperature regulation can help optimize health, performance, and overall well-being.

We dive into the role temperature plays throughout the sleep cycle, how sleep needs change with age, the impact of hormones and menopause on sleep quality, and how personalized sleep technology is helping people better understand and improve their rest. Dr. Moyen also shares practical strategies for athletes, insights into sleep stages, heart rate variability (HRV), chronotypes, and the future of sleep science.

Whether you’re an athlete looking to recover faster, navigating midlife sleep changes, or simply looking to wake up feeling more energized, this conversation offers valuable insights into the power of sleep optimization.
