Using Light (Sunlight, Blue Light & Red Light) to Optimize Health | Huberman Lab Podcast #68 | Andrew Huberman

In this podcast episode, Stanford professor Andrew Huberman explores the significant impact of light on our health. He explains how light acts as a vital signal that affects our biological processes, hormonal balance, sleep, and even skin health. Huberman discusses the benefits of different wavelengths, especially UVB and red light therapies, offering practical tips for using light to enhance well-being. He stresses the importance of getting natural light while warning against over-reliance on supplements. Additionally, he highlights science-based treatments and their immediate and long-term effects on hormones, particularly in relation to mating behaviors and cognitive function.
