What does the term "sleep architecture" describe?

The term "sleep architecture" refers to the structure and pattern of sleep cycles throughout the night. This encompasses the different stages of sleep, including REM (Rapid Eye Movement) and non-REM sleep, and how they occur in a cyclical pattern during a typical sleep period.

Sleep architecture is crucial for understanding the quality and restorative properties of sleep, as it reflects how long an individual spends in each stage and how many cycles occur throughout the night. An ideal sleep architecture contains several complete cycles of sleep, allowing for deep restorative sleep and necessary REM periods for cognitive functions and emotional regulation.

Other choices, while related to sleep, do not adequately capture the full definition of sleep architecture. The duration of REM sleep pertains to only one component of sleep architecture rather than its overall structure. Body temperatures during the night and brain waves during deep sleep focus on specific physiological elements and do not encompass the holistic view provided by sleep architecture.
