The Science of Sleep

Several of our sleep and circadian rhythm experts were featured in a 4-part webinar series by the University of Michigan Alumni Association.

Sleep is one of the most powerful tools we have for health. This four-part mini-course explores the science behind how sleep works, practical strategies for improving sleep quality, and what happens when sleep goes wrong. Along the way, we’ll examine changes across the lifespan, the impact of lifestyle and health conditions, and the truth behind common sleep myths. Through expert insights and conversations, participants will gain both a deeper understanding of sleep and practical takeaways to rest better — no matter their age or circumstances.

Lecture 1: The Science of Sleep
What actually happens when we fall asleep? In this session, we’ll explore the biology of sleep — why we need it and what’s happening in the brain and body during different stages of rest. We’ll also explore circadian rhythms, gender differences, and how sleep changes across our lifespan.

Lecture 2: Foundations of Healthy Sleep
Good sleep doesn’t just happen — it’s built. This session will cover practical strategies for creating the conditions that support high-quality rest, from healthy routines and sleep environments to nutrition, stress management, and screen use. We’ll also look at real-world challenges — like parenting young children, navigating work schedules, or managing a busy lifestyle — and discuss ways to get better sleep even when circumstances aren’t ideal.

Lecture 3: When Sleep Goes Wrong
Insomnia, sleep apnea, restless nights — many of us know what it feels like when sleep doesn’t work the way it should. This session explores the most common sleep challenges and disorders, their effects on both physical and mental health, and how to recognize when it’s time to talk with your doctor. We’ll also discuss treatment approaches and coping strategies to help you move toward healthier sleep.

Lecture 4: Sleep Myths: Fact or Fiction?
