Are you getting the right light signals to perform at your peak? Most of us spend nearly 90 percent of our time indoors, missing the critical biological triggers our bodies need for sleep, recovery, and focus. In this episode of the Ready State Podcast, we dive deep into the world of biocentric lighting and how you can optimize your environment to match your natural circadian rhythm.

Kyle Harris, CEO of BrainLit, joins Kelly and Juliet Starrett to explain why light should be viewed as a biological signal rather than just a way to see. We explore the massive impact that light spectrum and modulation have on our health, from professional athletes in the NBA and NHL to surgeons and shift workers in hospitals. Learn how passive changes to your environment can act as a force multiplier for your health, helping you sleep better and recover faster without adding another task to your busy to do list.
