Ka-choo! Brrr. Yawnnnn.

Have you ever wondered what makes you sneeze when you're in a dusty room? Or shiver when you get out of the bathtub? Or yawn when you're tired? All of these actions are reflexes. Your body makes them happen even though you don't tell it to.

Budding young scientists will be amazed as Melvin Berger and Paul Meisel reveal the mysteries behind the reflexes that happen in our bodies every day and offer fun-filled experiments to try on family and friends.

Kindergarten-Grade 2-This newly illustrated edition of Why I Cough, Sneeze, Shiver, Hiccup, and Yawn (Crowell, 1983) offers very basic explanations. In his trademark succinct style, Berger describes how automatic reflexes cause us to try to generate heat (shivering) or to get more oxygen (yawning). He also explains that the nervous system carries messages back and forth from the brain like telephone wires, and that these automatic reflexes help protect us from burning ourselves, from breathing in foreign objects, etc. In this new edition, the author suggests ways to test one's reflexes and describes "startle" reflexes and goose bumps. The writing is simple but effective, and the charming, colorful pen-and-ink and watercolors are much more detailed than the original black-and-white artwork by Holly Keller. Attractive introductory nonfiction.
