States of Consciousness The Function of Sleep Although everyone sleeps, no one really knows why people sleep. Researchers have proposed several theories to explain how sleep evolved to be a necessary behavior: People conserve energy by sleeping periodically. Sleep has a protective function, as it keeps people tucked away at night, safe from predators. Sleep restores body tissues that are depleted during daily activities. Sleep Research Sleep research has provided a lot of information about what happens to the brain and body during sleep. Researchers study sleep by monitoring subjects who spend the night in labs, and they use various instruments for different purposes: Electroencephalographs (EEGs): record brain waves Electromyographs (EMGs): record muscle activity Electrooculographs (EOGs): record eye movements Electrocardiographs (EKGs): record the activity of the heart Other instruments monitor breathing, body temperature, and pulse.
