What Happens When I Sleep?

We get warm and cozy under a quilt and drift off to sleep. As we rest, however, our bodies are still hard at work, processing dinner, repairing damaged skin, and growing bones and muscles. All night, every night, as we sleep and dream, our lungs keep breathing in and out, blood races around our body, our brains are busy organizing thoughts and experiences from the day, and repairs are being made ready for whatever tomorrow brings. In What Happens When I Sleep? the body parts and processes that keep on going all night are explored in detail. Fascinating facts are woven into lively, accessible step-by-step explanations, delivering solid science in a way that’s perfectly suited to the book’s Grade 2 readership.
