#001 - Research on Hunter-Gatherer Sleep - Professor Jerry Siegel, UCLA

In a ground-breaking study published in Current Biology, Professor Jerry Siegel at UCLA evaluated three societies living in natural conditions (e.g., modern day hunter-gatherers) to examine their sleep behaviors and physiology. He also analyzed external factors like natural light, ambient temperature and the season in which the data was collected. And by doing so, Dr. Siegel appeared to turn the wide-spread belief that we are chronically sleep deprived on its head. At least that seemed to be the emphasis of most news reports that came out describing the study. But to really understand what this data means, we need to discuss the study and interpret the findings with an emphasis to explain the difference between sleep period and sleep time. Here you can listen to my interview with Dr. Siegel where we discuss the study and his findings. Article on the subject found here: http://is.gd/a4iOTf
