Professor Glen Jeffery returns for Part 2 of our discussion on the science of light and human health. We explore how infrared and red light influence mitochondrial function, blood glucose regulation, systemic inflammation, ageing and recovery. Glen also discusses his latest research on circulating microvesicles, explains why modern LED lighting differs from natural sunlight, and shares practical ways to improve the light environment at home, at work and in hospitals. We also answer viewer questions about red light masks, incandescent bulbs, insulin and blue-blocking glasses.

Takeaways

  • Long wavelength light, including infrared, can significantly lower blood sugar levels.
  • Changing just a few LED components to include infrared can improve health outcomes.
  • Infrared light penetrates the body deeply and influences biological processes.
  • Hospital design is shifting towards outdoor exposure and natural light for healing.
  • There is a biphasic effect of red light panels — too much energy reduces effectiveness.
