Why does menopause cause insomnia and disrupted sleep?

Menopause can disrupt sleep because falling estrogen and progesterone levels may contribute to hot flashes, night sweats, difficulty relaxing, frequent awakenings, and waking too early. These changes can create a cycle of restless nights and low-energy days, while poor sleep may also worsen mood, concentration, productivity, and overall quality of life. Monitoring heart rate, oxygen levels, awakenings, and patterns of restlessness can help show whether symptoms are linked to hot flashes, interrupted breathing, or particular times of night. That information can give a woman and her healthcare provider a clearer basis for discussing sleep habits, symptom management, and whether additional treatment options should be considered.
