Document Summary
Circadian rhythm- regular recurrence of certain phenomena in cycles of approximately 24 hours. Hypopnea- a transient reduction in airflow during sleep, with diminished oxygen saturation. Insomnia- subjective perception of insufficient or non-restorative sleep. Non-rapid eye movement (nrem) sleep- first four stages of sleep. Obstructive sleep apnea-repetitive cessation (>10 seconds) of respiration during sleep. Rapid eye movement (rem) sleep- wakeful and active form of sleep during which dreaming occurs or tension is discharged. 50% of older adults complain of sleeping problems- not sleeping properly is not normally associated with aging. Rest, sleep, and activity contribute greatly to overall health (physical and mental well-being) Rest, sleep, and activity dependent on each other (e. g. poor rest/ sleep= low energy to engage in activities) Change in circadian rhythm- older adults tend to fall asleep earlier and wake earlier. Spend less time in deep sleep (stages 3 and 4) and less time in rem sleep (shortened and less intense)= non-restorative sleep; feeling unrested.
