Sarah TurnerBrain Red Light ExpertSarah is the founder and CEO of CeraThrive, with a science background and a focused interest in how light influences biology, particularly circadian rhythms, mitochondrial function, and brain health.Her perspective is shaped not only by research, but by hands-on experience, including involvement in clinical trials in neurodegeneration, where she saw first-hand the impact that targeted light therapies can have.What makes her valuable to podcast audiences is her ability to connect that science with real-world application. Rather than presenting health as a set of complex protocols, she explores how modern environments, especially disrupted light exposure, are quietly affecting energy, sleep, and long-term resilience.She also speaks to the idea of agency in wellness and ageing, drawing on both personal experience and ongoing research, and challenging the assumption that decline is inevitable.
