577: 55.05 Matthew Walker - REM and Non-REM sleep and criticality of each

NUGGET CONTEXT
Matthew speaks about how we sleep occurs in 90 minute cycles in the brain. He says that in that cycle there are multiple stages of Non REM sleep and REM sleep that occur in sequence. He also goes onto to talk about the various benefits of Non REM sleep (Immune system, memory storage, better blood pressure control etc) and REM sleep (creativity, empathy, reproductive health etc). He speaks about why sleeping 25% less in terms of hours could actually mean getting 60-90% less of REM sleep given the way the 90 minute cycles are organized.
GUEST
Matthew Paul Walker is a British scientist and Professor of Neuroscience and Psychology at the University of California, Berkeley. He is the author of the book - Why We Sleep (NY Times Bestseller, #1 Sunday Times Best seller). Previously, he was a professor of Psychiatry at Harvard Medical School. His research focuses on the impact of sleep on human health and disease. He has published more than 100 scientific studies and is the founder and Director of the Center for Human Sleep Science.
A lot of us grow up with the narrative of sleep being a residual figure in our lives where getting work done at the expense of sleep is seen as a victory of will power and mind over body. The reality is that there are dire consequences of trading off sleep for work or for exercise and it often shows up several years later. Given the delayed feedback loop and possible lack of attributability, many of us possibly end up ignoring it. Sleep constitutes about one third of our time on the planet and the quality of sleep possibly accounts for the effectiveness of the remaining two thirds of our time on the planet.
