Ultimately, Sleep Revolution tells us very little about what we need to know to get more sleep. Huffington’s slender thesis (“Sleep more so you can make more money”) is covered fully in her 4-minute TED talk on the subject, and solutions to sleeplessness are available in innumerable resources on the internet. The book is less important for what it says and more for what it reveals about Huffington’s place in enabling a particularly rapacious form of capitalism, one which first deprives people of sleep and then sells them the methods by which they might regain some of it.
