There are typically five stages of sleep, which are categorized into two main types: non-REM (NREM) and REM sleep. NREM sleep includes stages 1, 2, and 3, with stage 1 being light sleep, stage 2 being a deeper sleep, and stage 3 (also known as slow-wave sleep) being the deepest stage. REM sleep, which occurs after the NREM stages, is characterized by rapid eye movement and increased brain activity, often associated with vivid dreaming. These stages repeat in cycles throughout the night, usually lasting about 90 minutes each.
