Screens before bed: what the sleep reviews actually say

The sleep evidence on screens is more consistent than the language evidence. It is still mostly observational. Here is the review.

The claim

Screen use is consistently associated with later bedtimes and shorter sleep in school-aged children.

Associative claim. Evidence strength is chosen by the person who posts, based on the sources they read. Never by AI.

How to Make a Difference: Part 1

Why do some people act on the possibilities before them, while others come to believe that nothing they do will make a difference? Psychologist Martin Seligman describes his groundbreaking research on learned helplessness, and explains how the stories we tell ourselves about setbacks can shape what we do next. We also explore how optimism can help us rediscover our ability to change things for the better. If you have a question or comment about the science of optimism and pessimism that you'd be willing to share with the Hidden Brain audience after listening to this episode, please find a quiet room and record a voice memo on your phone. Email the file to us at feedback@hiddenbrain.org. Use the subject line: “How to Make a Difference.” If you love Hidden Brain in audio, check out our video series on YouTube. You'll find episodes there about memory, focus, getting unstuck, and much more at youtube.com/@hiddenbrain. Hosted by Simplecast, an AdsWizz company.
