In this episode of the Brain Architects, Lindsey Burghardt, MD, MPH, FAAP, talks with Rebecca Spencer, PhD, a researcher on the science of sleep, about why sleep is so essential during early childhood. From brain architecture and emotional regulation to the role of naps and the importance of creating cool sleeping spaces in our warming world, Dr. Spencer explains how sleep shapes early childhood health and lifelong well-being.

With information for caregivers, educators, and policymakers, this conversation offers a deeper understanding of how creating environments that promote good sleep supports children’s learning, health, and resilience.
