Shownotes

We spend about one third of our lives sleeping. For many of us, me included, sleep is one of life's greatest pleasures. For others, falling and staying asleep and sleeping well is a constant battle. But what is sleep exactly, and why must we do it every night? Answering these questions are some of the biggest and most fascinating challenges biologists face today.

We do know that sleep is as essential to our life and wellbeing as food and water. Sleep is the time when our body repairs itself. Sleep, or the lack of it, affects every aspect of our lives, from immunity, to hormones, to our mood and cognitive function. A lack of sleep makes us vulnerable to many chronic medical issues and affects us not only as individuals, but as a society, considering the impact of car accidents or disasters such as the Exxon Valdez oil spill. Knowing about sleep and how to optimize it could literally save your life or that of someone you love.

My guest today is an authority on the neurobiology of sleep and circadian rhythms. Dr. Craig Heller is an award winning professor of biology and researcher at Stanford University and has been studying why we sleep and the ways that sleep can support physical performance. 

Dr. Heller will share with us his hypothesis about the purpose of sleep, some of his key insights about how the clock in our brain works and how to harness the power of sleep.
