Why We Sleep - The Great Sleep Challenge
Shownotes
In this episode of The Self-Driven Child Podcast, I sit down with my longtime partner, co-author, and neuropsychologist Dr. William Stixrud to dig deep into something hiding in plain sight: sleep. We talk about why so many kids, teens, and frankly adults are walking around chronically exhausted—and what that’s quietly doing to learning, emotional health, and overall well-being. This conversation grew out of a powerful question a student asked us after we issued a real-world “sleep challenge,” and it opened the door to a fascinating look at how sleep actually works in the brain.
Bill and I explore what happens when kids don’t get enough rest, why tired brains struggle with attention, memory, and emotional regulation, and how sleep might be one of the most underestimated tools we have for supporting mental health, learning, and resilience. If you care about helping kids thrive—and about thriving yourself—this is one you won’t want to miss.
