Physiological Changes in Aging
| Category | Normal Changes (Not Pathological) |
|---|---|
| Sexuality | • Sexual interest does not significantly decline with age • Partner availability is the strongest predictor of sexual activity Men: slower erections, longer refractory period, require more stimulation Women: vaginal dryness, thinning of vaginal epithelium |
| Sleep | • Early-morning awakenings are common • Decreased deep sleep (↓ slow-wave sleep) • REM sleep remains stable until age >85 |
