Sleep is the last frontier of productivity

The Sleep Dividend unveils the strange new world where companies, scientists, and designers compete to capture what was once private: the human act of rest.

From nap pods in Silicon Valley to Tokyo's "micro-sleep salons," the book traces the evolution of rest from biological necessity to business strategy. It follows the neuroscientists decoding the architecture of fatigue, the startups monetizing recovery, and the workers learning that rest itself has become labor.
