"Are you getting enough sleep? Are you sure? This engaging, fact-packed look at the science of sleep will make you think again. For something that all humans (and most animals) do for hours every night, sleep is not as well understood as you might think. Scientists don't even really know why we sleep! But they know it's important. And this book takes readers through just why it's so important, what your body's doing while you're dreaming, what happens when you don't sleep enough, and why the science of sleep research began in a centipede-infested cave. With tons of fun facts about nightmares, sleepwalking, how sleep makes you smarter and much more, Snoozefest is far from a snore. What happens after you shut your eyes at night is way more interesting than you thought."--
