How does sleep architecture change with aging, and what nonpharmacologic approach can help?

• A. Increased REM sleep; taking naps mid-day.
• B. Reduced slow-wave sleep and more awakenings; regular schedule and daytime activity help.
• C. No change in sleep; sleep more at night.
• D. More deep sleep; avoid daytime activity.

Answer: (B)

Sleep architecture shifts with aging, with a clear decrease in deep, slow-wave sleep and more awakenings during the night. This makes older adults’ sleep lighter and more fragmented, so they often wake briefly or wake earlier and have more trouble staying asleep. A nonpharmacologic approach that helps addresses this pattern by supporting the body's internal clock and sleep-wake balance. Keeping a regular schedule for going to bed and waking up, plus staying active during the day (ideally with daytime light exposure), reinforces circadian cues and improves sleep consolidation. The consistent routine helps reduce unnecessary nighttime awakenings and makes nighttime sleep more restorative by preserving the portion of sleep that remains, especially the lighter, more restorative phases, while daytime activity supports alertness and better sleep pressure at night. The other options don’t fit the typical aging pattern: one suggests increased REM sleep and mid-day naps, which doesn’t counteract the common loss of deep sleep and increased awakenings; another claims no change in sleep, which isn’t accurate for most older adults; and another proposes more deep sleep, which is the opposite of what aging usually shows.
