How long does sleep disruption last during perimenopause?

The duration of sleep disruption during perimenopause varies significantly from person to person. Some women experience sleep disruption for a few months, while for others it can persist throughout the entire perimenopause transition, which typically lasts 4 to 10 years.

Sleep disruption tends to fluctuate rather than remain constant. You may have weeks or months where it improves, followed by periods where it returns. This pattern reflects the unpredictable nature of hormone fluctuations during perimenopause.

Factors that influence how long sleep disruption lasts include your genetics, stress levels, sleep quality, diet, exercise habits, and whether you pursue treatment. Many women find that sleep disruption improves or resolves once they reach menopause (12 consecutive months without a period), though some symptoms can persist into postmenopause.

Tracking sleep disruption over time helps you see the bigger pattern. What feels endless in the moment often shows improvement trends when you look at monthly or quarterly data.
