Understanding Your Sleep During Perimenopause

Every night, your body shares a quiet narrative, one written in the hours you rest, the moments you wake, and the subtle movements you make without even noticing. These patterns aren’t random. They’re meaningful signals reflecting how your nervous system, hormones, and overall wellbeing are shifting through perimenopause.
By tracking movement patterns, heart rate, and changes in skin conductance, Peri can interpret these signals and translate them into clear sleep metrics that show how your body is truly resting.

Why Your Sleep Patterns Matter
Sleep isn’t just “Did I get enough?”
It’s How did my body move through the night?
And What does that say about how supported I feel?
Peri brings these insights together so you can see what your nights are telling you, clearly, and in real time.
Here’s what your nightly data will show:
Total Time Asleep
This is your overall sleep window, the foundation of restoration. During perimenopause, fluctuating hormones like estrogen and progesterone can make this number shift from night to night. That doesn’t mean you’re doing anything wrong; it simply reflects the changing rhythm of your body.
Nocturnal Wakes
Waking in the night becomes more common in perimenopause. Temperature changes, stress, hormones, and lighter sleep stages can all contribute. These wakes help paint a picture of how settled or unsettled your system feels.
Tosses and Turns
Those small, restless movements are subtle but meaningful. They often appear before you consciously wake up and can indicate tension, discomfort, or fragmented sleep. Tracking them shows how restful your sleep truly is, not just how long you stayed in bed.
Together, these pieces form your nightly landscape. With time, Peri helps you make sense of it: why some mornings feel light and energised, and others arrive with a foggier, more depleted start.
A Time of Change, A Need for Clarity
Perimenopause can make your nights feel less predictable, Peri is here to bring clarity to these shifts.
By showing you what’s happening during the night, Peri helps you find context and reassurance during a phase that can feel anything but steady.
Rather than relying on guesswork or averages, Peri reflects your real sleep data, helping you understand:
There’s no need for perfect charts or flawless nights, just the truth of what your body is experiencing, with Peri helping you make sense of it.
