Morning naps may signal health issues in older adults, study finds

Using objective wrist-monitor data from the Rush University Memory and Aging Project, researchers found that longer and more frequent naps, especially morning naps, are linked to higher all-cause mortality over 19 years (about 13% higher per extra nap hour, 7% higher per additional nap per day; morning nappers ~30% higher risk than early-afternoon nappers). The relationship is correlational, not causal, and naps may reflect underlying disease or circadian disruption; wearable nap monitoring could help flag health issues early.

Insomnia Linked to Delayed Brain Clock That Hinders Nighttime Wind-Down

Australian researchers find chronic insomnia may stem from a delayed brain circadian clock that prevents the mind from winding down at night. In a 24-hour lab study with 32 older adults, insomniacs showed weaker nighttime disengagement and about a 6.5-hour delay in cognitive peaks, indicating circadian misalignment; the work suggests circadian-focused treatments such as timed light exposure, structured routines, and mindfulness could help restore night-time brain downshifting beyond standard behavioral therapies.
