Arianna Huffington, The Sleep Revolution
Huffington's book juxtaposes her own experiences in learning to get a better night's sleep with a blend of science, personal anecdotes, and scenes of how sleep has been perceived over the years. There's a good overview of contemporary thought on sleeping — from the disastrous effects of too little of it to the problematic side effects that can come as a result of taking medication to aid in one’s slumber. The Sleep Revolution provides a good window into just what's at stake when sleep is involved, and how more sleep can make for a better world. And it covers a vast territory, from meditation to changes to corporate cultures to fitness to the way we schedule work and education.
