Dr. Matt Walker: The Biology of Sleep & Your Unique Sleep Needs | Huberman Lab Guest Series

About this video

Dr. Matt Walker opens his six-episode sleep series with Huberman by explaining why sleep matters and what happens without enough of it. Walker introduces the QQRT formula, quality, quantity, regularity and timing, as the way to identify your own optimal sleep. He cites the daylight saving time transition as a natural experiment, describing a reported 24% relative increase in heart attack risk after losing an hour of sleep in spring and a reduction when an hour is gained in autumn, alongside effects on car accidents, suicide rates and even judges’ sentencing. Walker also describes a study in which limiting healthy people to six hours of sleep for a week distorted the activity of hundreds of genes compared with fuller sleep.
