Scott Zimmerman, an optics engineer and founder of Naira, along with Andrew LaTour, a photobiomodulation expert and founder of Gemba Red, delve into the health impacts of indoor lighting. They highlight how near-infrared light deficiencies contribute to health issues and disrupt sleep. The duo discusses the importance of mimicking natural light for enhancing well-being, emphasizing the therapeutic benefits of red light therapy. They also explore how modern lighting technologies can better align with our biological needs, promoting optimal circadian rhythms and overall health.

Combating Overregulation
Push back against government overreach in lighting regulations, like the DOE's lumen-per-watt rule change.
Advocate for less government intervention in technology development to foster innovation and competition.

NIR Deficiency
Near-infrared (NIR) deficiency, stemming from reduced exposure to incandescent bulbs and natural light, impacts health.
Red light therapy and NIR-incorporating bulbs can help address this deficiency and improve well-being.

Delayed Light Therapy Response
The body responds to light therapy in a delayed manner, with peak ATP production occurring hours after treatment.
Think of light therapy as flipping a switch that triggers a cascade of effects rather than real-time charging.
