Humans spend one-third of their life sleeping, yet the purpose and function behind this regular state of unconsciousness remains a biological mystery. Sleep researcher Giorgio Gilestro is trying to understand some basic questions about it: like what sleep exactly is, and why it’s even necessary. Seeking A Scientist is a production of KCUR Studios. It's made possible with support from the Stowers Institute for Medical Research, where scientists work to accelerate our understanding of human health and disease. It's hosted by Dr. Kate Biberdorf, AKA Kate the Chemist. This episode was mixed by Olivia Hewitt and Suzanne Hogan. Our senior producer is Suzanne Hogan. Our editor is Mackenzie Martin.
