Circadian rhythm- body"s natural 24 hour cycle, roughly matched to day/night cycle of light/dark. Body temp. , arousal/energy, and mental sharpness vary based on part of cycle. Sleep stages- distinct patterns of brain waves and muscle activity that are associated with different types of consciousness and sleep. Alpha waves are relatively slow brain waves of a relaxed, awake state. Eventually brain waves change from alpha to nrem-1 waves. Nrem-1, nrem-2, nrem-3 are non-rem sleep stages (falling into. Rem sleep- dreams occur during period of wild brain activity and rapid- eye movements.
