The document discusses the sleep cycle and stages of sleep. It describes how sleep is studied using EEG, EOG, EMG and EKG recordings. There are 5 stages of sleep: awake, stages 1 and 2 which are light sleep, stage 3 and 4 which are deep sleep, and REM sleep. The sleep cycle repeats every 90 minutes, alternating between REM and non-REM sleep. REM sleep increases later in the night and is when dreaming occurs. Lack of sleep can negatively impact mood, cognitive performance, and health.

tucking away at night, safe from predators.
• Recuperative Theory: Conserves energy, restores body
tissues depleted during daily activity
– REM: hormones released that influence thinking &
memory formation, mental organization; counteract
fatigue, irritability, inattention

release of growth hormone)
