Key Concepts

Sleep Architecture

Sleep architecture refers to the organization of various sleep stages throughout the night, including deep sleep (slow-wave sleep) and REM sleep. With age, the overall structure of sleep can change; older adults often experience a reduction in deep sleep, alterations in REM cycles, and an increase in lighter sleep stages, which can affect the restorative quality of sleep.

Circadian Rhythms

Circadian rhythms are the body’s natural 24-hour cycles that regulate sleep and wakefulness. As people age, these rhythms can shift, often resulting in an earlier onset of sleepiness in the evening and earlier waking times in the morning, a phenomenon known as phase advance.

Sleep Duration and Efficiency

Sleep duration refers to the total amount of sleep, while sleep efficiency measures the quality of sleep by comparing the time spent asleep to time in bed. Aging can lead to more fragmented sleep, resulting in shorter periods of uninterrupted sleep and decreased overall sleep efficiency.

Sleep Disorders

The prevalence of sleep disorders tends to increase with age. Conditions such as insomnia, sleep apnea, and restless legs syndrome become more common in older adults, further contributing to changes and disruptions in sleep patterns and overall sleep quality.
