Sleep is essential for life, but its measurement has a brief his-tory in evolutionary terms. The most widely accepted way of measuring sleep is via sleep stages derived from analysis of the electroencephalogram (EEG) which was first introduced by Loomis et al. [1] in 1937. Loomis et al. observed the continual changes of stages during sleep and identified five stages with the letters A-E with A containing trains of alpha waves, B sections of low voltage, C containing spindles, D containing spindles plus random potentials, and E containing random potentials only.
