This podcast episode explores the relationship between screens and sleep, debunking the widely held belief that screen light is the sole culprit for sleep disturbances. Recent research has shown that factors such as screen brightness, color, content, and individual differences all play a significant role in impacting sleep. While blue light can have alerting effects, self-regulation and setting bedtimes are key factors in maintaining healthy sleep hygiene. The episode also discusses the impact of technology on sleep in adolescents, the importance of scientific integrity in industry, and the need for effective science communication to the public.
