The 3 a.m. wake-up: Why it happens to women more often after 55

Waking up in the middle of the night happens to women more often after age 55 due to many factors. These include diminished hormones and circadian rhythm changes. Stress, bladder changes, medications, chronic pain, and alcohol and caffeine use can also contribute. People can break the cycle of nighttime wake-ups by practicing good sleep hygiene, addressing medical issues, trying mind-body techniques such as deep breathing or meditation, and limiting caffeine, alcohol, and heavy evening meals.
