    Sleeping is a universal, yet poorly understood phenomenon that comprises five progressively deeper stages.

    Some people may find it frustrating that we humans spend around a third of our lives asleep, but they can comfort themselves with the fact that sleep is a universal phenomenon: every animal on the planet sleeps.

    It’s interesting though that there seems to be little relationship between an animal’s size and position in the food chain, and the amount of sleep they need: tigers and squirrels typically get about 15 hours of shuteye each day, while giraffes, on the other hand, make do with just an hour and a half. Dolphins and some birds have even mastered the art of only half-sleeping: one hemisphere of their brain remains awake to watch out for predators, while the other sleeps.

    Despite its universal nature, the true biological function of sleep remains something of a mystery.

    In fact, up until the 1950s, scientists showed little interest in sleep, as it was commonly believed that the brain was not really doing anything interesting as it slept.

    It was only in 1952 that a breakthrough came: scientists observing sleeping subjects discovered to their surprise that in the middle of the night their subjects’ eyes began to move around rapidly. This phenomenon was aptly named rapid eye movement or REM.

    After further studies, it was found that in fact sleep consists of five stages that we cycle through repeatedly, each cycle taking roughly 1.5 hours.

    In the first four stages, the brain goes into progressively deeper sleep, which is shown by the fact that someone woken up in the first stage may not even realize that they were sleeping, whereas someone woken in stage four will feel severely disoriented.

    The fifth stage of sleep is the REM stage, where the brain actually emerges from deep sleep and has been shown to be as active as if you were awake. Perhaps this explains why REM sleep is also the time when most dreams occur.
