What is the function of sleep? Why does the northern fur seal sleep with only half of the brain? Is it safer to be asleep or awake? For the first time, the inside story of one of life’s most mysterious and unexplored phenomenons. Written by a fellowship trained sleep medicine physician, Sleep 101 is at once a guide to hitherto uncharted biological territory, and a much needed tool for those seeking to improve their sleep.
