Brainy Beds? Professor David Samson on Sleeping Platforms, Sleep Quality, and Thinking Speed, plus News!

Did our brains evolve as they have due to how we slept? In part, likely yes. In this episode of the humanOS Radio podcast, I speak with Professor David Samson about his research looking at primate sleeping platforms and their potential role to increase the cognitive abilities of certain great apes beyond the capacities of other primates. How does this connection work? The primates who create more comfortable beds for themselves appear to achieve substantial amounts of deep and REM sleep over the night. This is turn may have lead to the expansion of cognitive abilities over time. Can you benefit from the information shared in this discussion to improve your own sleep?


A meta-analysis of the Paleolithic nutrition pattern; an interview of authors

Just today, the American Journal of Clinical Nutrition – the most prestigious nutrition journal in the world – published a systematic review and meta-analysis of the paleolithic nutrition pattern (the Paleo diet).

The audio interview below is with study authors, Hanno Pijl, M.D., Ph.D., and Ester van Zuurin, M.D., both of Leiden Unversity in the Netherlands. They, along with authors Eric Manheimer and Zbys Fedorowicz, first performed a systematic review of six online publication libraries for all possible qualifying research. From there, they winnowed the list to four studies, pooling together 159 subjects for their analysis, looking for mean differences in primary endpoints related to metabolic syndrome: 1) Waist circumference, 2) Blood pressure, 3) Triglycerides, 4) HDL cholesterol, and 5) Blood sugar concentration. Secondary endpoints included change in body weight, even though some of the studies included in the analysis tried to prevent weight change so that the results would be less confounded by it. Weight loss, while healthy for someone who is overweight, can also improve these endpoints independently, making it harder to know if it is the nutritional properties of the diet or the weight loss that influenced results. We discuss this specifically in the interview, which you can listen to it here in its entirety.


The Freakonomics of Sleep (Part 1)

Back in May of this year, I give a presentation entitled Sleep, Productivity, and Peak Performance at a CEO summit in Manhattan hosted by VC firm, Firstmark Capital. After I presented, Steven Dubner of Freakonomics spoke about the man who smashed the world record at Nathan’s hot dog eating contest. See more about this story in the blog post. After we both presented, Dubner approached me for an interview to discuss sleep. My interview was included in the two-part series that they just published on the subject.
