Perimenopause represents a critical window for understanding and optimizing long-term health. Yet for decades, women have been told their symptoms are “normal,” without access to the data needed to truly understand what is happening in their bodies.

Today, we’re sharing our Peri Science & Consumer Report 2026, a report grounded in cutting-edge research and real-world biosensor data from women wearing Peri. It explores how common midlife symptoms connect to cardiovascular health, brain health, sleep, and stress, and why this life stage matters far beyond day-to-day comfort

Why Perimenopause Matters

Symptoms during perimenopause can feel confusing: they change week to week, disrupt sleep, and often arrive without clear explanation. But research increasingly shows that experiences like hot flashes, night sweats, sleep disruption, and emotional stress are not just inconveniences—they may be signals linked to long-term health patterns.

Importantly, these findings do not mean symptoms cause disease. Instead, they highlight perimenopause as a meaningful window to pay attention, build healthier habits, and advocate for better, more personalized care

What the Report Highlights

Drawing on peer-reviewed science and early insights from real women wearing Peri, the report surfaces several key themes:

• Symptoms cluster more than we realize
  One of the clearest insights from the Peri community is the frequent combination of sleep difficulties and vasomotor symptoms (hot flashes and night sweats)—a pairing that can amplify effects on stress, mood, and vascular regulation.

• Self-reporting misses what happens at night
  In our data, 46% of hot flashes and night sweats are underreported when relying on self-report alone—often because episodes occur during sleep, are brief, or are hard to remember later. Continuous, objective measurement adds crucial clarity.

• Sleep is central to long-term wellbeing
  Large real-world studies show sleep disturbance is widespread during perimenopause and linked to worse quality of life and mental wellbeing, whether or not vasomotor symptoms are present.

• Early signals, not diagnoses
  Exploratory data suggest differences in overnight blood-flow stability among women with vasomotor symptoms. These are early, group-level patterns—not diagnoses—but they underscore why midlife is such an important time to pay attention.

• Women want tools that fit real life
  Women who wore Peri reported strong improvements in understanding their symptoms, confidence wearing the device, and perceived quality of life—without disrupting how they live day to day.
