MedCram Episode 138. Infrared Light Reduces ICU Stay
Nov 22, 2025
Roger Seheult, MD, explores groundbreaking research on the effects of infrared light on ICU stays. A study reveals that specific wavelengths can penetrate the body and enhance mitochondrial function. He discusses a Brazilian trial where LED vests significantly shortened COVID-19 hospitalizations. The podcast highlights the financial benefits of reduced stays for hospitals and patients alike. Additionally, Roger stresses the importance of sunlight in healing and considers modern practices that limit infrared exposure, suggesting new practices could revolutionize patient care.

Episode notes
Deep Penetration Of Infrared Light
- Infrared (850–880 nm) can penetrate the entire human body and produce systemic mitochondrial effects.
- The 2025 Nature Scientific Reports paper shows distal (abscopal) effects including improved retinal function.
Visual Demonstration Through Tissue
- The paper visually demonstrated IR passing through tissues using Bob Fosbury's hand and a thorax image.
- Sensitive detectors revealed light transmission even through 30 cm of thorax tissue.
Brazilian LED Jacket COVID Trial
- A Brazilian randomized study used 940 nm LED jackets for 15 minutes daily in COVID-19 inpatients.
- Near‑infrared recipients had shorter hospital stays (8 vs 11.7 days) despite starting sicker.
