What People Say
Why We Sleep is the book that other health and science authors reach for when they need to make the case that sleep is non-negotiable. Peter Attia treats it as a longevity pillar in Outlive, Matt Richtel cites Walker's finding that one night of poor sleep drops natural-killer-cell activity by 70 percent, and Bill Bryson leans on it for his chapter on sleep in The Body.
Johann Hari draws on Walker in Stolen Focus to argue that sleep deprivation is a core driver of attention collapse, while James Nestor and Satchin Panda extend Walker's research into breathing and circadian science respectively. The book is widely praised for making the science alarming and actionable, though some researchers have flagged that Walker occasionally overstates findings or presents correlational data as causal.
