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.

How are sleep stages measured?
Sleep stages are measured using polysomnography, a comprehensive test that records brain activity, eye movement, muscle tone, heart rate, and breathing patterns. Electroencephalography (EEG) is primarily used to track brain waves, helping to identify different sleep stages such as REM and non-REM sleep. Additionally, other sensors monitor physical changes, providing a complete picture of the sleep cycle and its various stages. This data allows for the assessment of sleep quality and any potential sleep disorders.

The correct order for the sleep stages is as follows: Stage 1 (light sleep), Stage 2 (light sleep with sleep spindles), Stage 3 (deep sleep), and REM (rapid eye movement) sleep.

This cycle repeats several times throughout the night, with each cycle lasting about 90 minutes.
