#70 - Sleep & Screens with Dr. Michael Gradisar

The Matt Walker Podcast

In today's podcast episode, Matt welcomes back Dr. Michael Gradisar to delve into the evolving understanding of screens and sleep. Initially holding the belief in the detrimental effect of screen light on sleep, Matt finds this notion challenged by Dr. Gradisar's research, which emphasizes a more nuanced perspective. Their discussion highlights the shift from simplistic concerns about screen use to acknowledging the multifaceted influences on sleep, including content and individual differences.

Dr. Gradisar's experiments, such as exposure to violent video games and bedtime displacement monitoring, emphasize the complexity of the relationship between technology use and sleep, stressing the need for personalized approaches to addressing sleep issues. His dialogue with Matt underscores the importance of scientific inquiry in challenging and refining commonly held beliefs about technology and sleep, advocating for a nuanced understanding that considers individual behaviors and differences. Furthermore, both speakers encourage researchers to engage with industry and the public, translating findings into practical advice for improving sleep hygiene and promoting healthier sleep practices.
