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.
