Lighting for Human Health: NASA Scientist Robert Soler on the Future of Biological Lighting

In this episode of Earth‑Centric Lighting, Travis sits down with Robert Soler—former NASA Subject Matter Expert in circadian lighting and co‑founder of BIOS Lighting—to explore how light can transform human mental, emotional, and physical well‑being. Soler shares insights from his work developing lighting for astronauts and explains how those same principles now guide BIOS Lighting’s mission to bring biologically meaningful light into homes, workplaces, schools, and healthcare environments.

Together, they discuss the science behind circadian entrainment, the biological need for high daytime light levels, and how modern indoor environments often fail to meet those needs. Soler breaks down how the right spectrum and intensity of light can support sleep, mood, alertness, and overall health—echoing research showing that optimized lighting can significantly reduce symptoms associated with PTSD, depression, and bipolar disorder. He also explains how architects, designers, and homeowners can use these insights to create spaces that support human thriving.

Whether you’re a designer, builder, wellness professional, or simply someone who wants to feel better in your own home, this conversation reveals how lighting can become one of the most powerful tools for human health.
