Guida verificata passo dopo passo1
Understand the structure of a typical night's sleep, which is composed of multiple sleep cycles.
Recognize that each sleep cycle includes both Non-REM (NREM) and REM stages, and these cycles repeat several times throughout the night.
Note that Non-REM sleep does not occur only once; instead, it happens multiple times as part of each cycle.
Acknowledge that dreaming primarily occurs during REM sleep, which happens multiple times, not just in the first hour.
Conclude that the correct statement is that a night's sleep typically consists of multiple cycles of REM and Non-REM sleep.
