Sleep Quality Declines With Age
- Sleep quality declines with age, showing reduced efficiency and more fragmented, lighter sleep.
- These changes include less slow-wave and REM sleep, and earlier, weaker circadian rhythms with reduced melatonin.
Sleep Changes Aren't Always Negative
- Not all age-related sleep changes are necessarily harmful or pathological.
- Many reflect normal developmental changes rather than poor health effects.
Activity Preserves Sleep Quality
- Sleep deterioration links with inactivity, health issues, medication, and less outdoor time.
- Those maintaining physical, cognitive, and social activity often preserve better sleep quality.
