Understand the typical changes in sleep architecture that occur during middle adulthood, focusing on the stages of sleep such as REM sleep and slow-wave sleep (deep sleep).
Recall that slow-wave sleep (SWS) is the deepest stage of non-REM sleep and is crucial for physical restoration and memory consolidation.
Recognize that research shows adults in middle age commonly experience a reduction in the amount of slow-wave sleep, which affects sleep quality.
Consider that while total sleep time may decrease slightly, the most notable change is the decrease in deep sleep rather than a shift in bedtime or a large increase in REM sleep.
Evaluate the options by comparing them to known sleep pattern changes in middle age, identifying that a decrease in deep sleep is the most common and well-documented change.
