Study Notes
Sleep Across the Lifespan
- Significant changes occur in sleep patterns throughout an individual's life.
- Key aspects of sleep evolving over time include:
- Sleep onset: the time at which sleep begins.
- Sleep duration: total hours of sleep obtained.
- Awakenings during sleep: frequency of interruptions while sleeping.
- Proportion of REM sleep: percentage of sleep that is rapid eye movement.
- Proportion of NREM sleep: percentage of sleep that is non-rapid eye movement.
Trends in Sleep Patterns
- Total sleep duration decreases with age, from approximately 16 hours in infants to about 6 hours in older adults.
- Total NREM sleep declines from around 8 hours to 4.5 hours with aging.
- Total REM sleep decreases significantly from 8 hours to 1.5 hours across the lifespan.
- The percentage of REM sleep relative to total sleep diminishes from 50% in infants to 20% in older adults.
- Conversely, the proportion of NREM sleep increases, rising from about 50% to 80% as one ages.
Functions of Sleep Types
- REM sleep is crucial for mental restoration, aiding brain function and cognitive development.
- NREM sleep plays an essential role in physical restoration, facilitating tissue and cell repair.
- Increased REM sleep is commonly observed in infants and individuals experiencing emotional stress.
- Post-physical exertion, such as after running a marathon, individuals tend to spend more time in NREM sleep, reflecting the body's need for recovery.
Additional Notes
- Refer to tables 1, 2, and 3 on pages 307-308 for further details.
- Recommendations for students to compile an abbreviated table summarizing:
- Age group
- Characteristics of sleep
- Explanations of changes
- Healthy sleep requirements
- Average sleep patterns.
