Aging Reduces Sleep Quality and Duration
Aging causes reduced deep sleep, increased nighttime awakenings, and shifts in circadian rhythms, resulting in poorer overall sleep quality.
- Aging leads to more interruptions, reducing restorative rest phases.
- Changes in internal clock cause earlier bedtimes and wake times.
