Hormones shape how you sleep, how much energy you have, how you feel emotionally
For generations, hormonal health has lived in the margins of medicine — measured rarely, interpreted in isolation, and seldom connected to the rhythms of daily life. Now, a partnership between Oura Ring and hormone tracker Mira brings lab-grade hormone data into the continuous stream of sleep, energy, and recovery metrics that women already monitor. The integration, available beginning February 2026, represents a quiet but meaningful shift: the body's hormonal story is no longer a single data point extracted in a clinic, but an ongoing conversation woven into everyday awareness.
- Women have long navigated hormonal changes — perimenopause, fertility windows, cycle fluctuations — with little more than intuition and infrequent lab visits to guide them.
- Mira's fluorescence-based monitor can measure LH, FSH, estrogen, and progesterone metabolites from a urine sample in under 20 seconds, matching clinical precision in a device small enough to sit on a bathroom shelf.
- The new Oura integration surfaces hormone data directly alongside sleep scores and readiness metrics, letting users draw real-time connections between hormonal shifts and how their bodies feel and perform.
- Early use cases are already taking shape: confirming ovulation, anticipating low-energy days, and arriving at medical appointments with concrete numbers rather than vague descriptions of fatigue or mood.
- Data privacy is anchored in HIPAA and GDPR compliance, with explicit user consent required before any information crosses between platforms and a firm policy against selling personal health data.
Oura Ring, the finger-worn sleep and wellness tracker, has partnered with Mira — maker of a small, egg-shaped hormone monitor — to bring lab-grade hormonal data into the daily wellness tracking experience for the first time. Users can now view luteinizing hormone, follicle-stimulating hormone, estrogen metabolites, and progesterone metabolites alongside their familiar Oura sleep scores, readiness metrics, and body temperature readings.
The process is simple: dip a Mira test wand into a urine sample, insert it into the monitor for 16 seconds, and the results sync to the Mira app, where they appear beside Oura data. The result is something genuinely new — a window into why sleep quality dipped on a given night, or why recovery felt harder than expected, grounded in actual hormone levels rather than guesswork.
Mira CEO Sylvia Kang has been direct about what the partnership is trying to correct. Hormones have historically been treated as isolated lab results rather than the continuous, daily influence they actually are on energy, mood, and resilience. The integration is designed to close that gap — giving women navigating perimenopause, menopause, or fertility tracking the kind of longitudinal hormonal visibility that has never existed in a consumer product before.
The collaboration also carries practical medical value. Users can bring real hormone data correlated with measurable health metrics into conversations with their doctors, replacing vague complaints with specific, timestamped patterns. Privacy protections are embedded throughout: Mira requires explicit consent before sharing any data with Oura, personal health information is never sold, and all data handling flows through HIPAA and GDPR-compliant systems.
Oura Ring, the sleep and wellness tracker worn on your finger, now connects to something most health apps have ignored: your hormones. The partnership is with Mira, a company that makes a small egg-shaped monitor capable of measuring hormone levels from urine samples with the same precision used in clinical laboratories. Starting now, Oura users can see their hormone data—luteinizing hormone, follicle-stimulating hormone, estrogen metabolites, and progesterone metabolites—displayed alongside their sleep scores, readiness metrics, and body temperature.
This is the first time lab-grade hormone measurement has been woven into the daily wellness tracking experience. Until now, hormones were something you measured once in a doctor's office, got a number, and then moved on. Mira's CEO Sylvia Kang describes the old approach as fundamentally disconnected from how women actually live. "Hormones have traditionally been treated as something you measure in isolation," she says. "But that's never how women actually experience their bodies." The new integration treats hormones as what they are: a constant influence on sleep quality, energy levels, emotional resilience, and how your body recovers day to day.
The mechanics are straightforward. You use one of Mira's test wands by dipping it in a urine sample, insert it into the monitor for 16 seconds, and the results sync to the Mira app. From there, you can view the same data alongside your Oura metrics—seeing, for instance, why you slept poorly on a particular night or why your readiness score dipped. The hormone monitor tracks four key markers: LH and FSH, which regulate ovarian function and fertility; E3G, a measurable form of estrogen in urine; and PdG, the progesterone metabolite your body produces.
The practical applications are substantial. Women navigating perimenopause or menopause gain visibility into what's happening inside their bodies at a moment when hormonal shifts can feel chaotic and unexplained. Those tracking fertility or their menstrual cycle can use the data to confirm ovulation and plan recovery days. The information also gives people concrete details to bring to their doctors, moving beyond vague descriptions of fatigue or mood changes to actual hormone numbers that correlate with measurable health metrics.
Privacy protections are built into the system. Mira requires explicit consent from users before sharing data with Oura, and the company's policy is clear: personal health data stays confidential and is never sold to third parties. Any anonymized data used to improve the app experience flows only through HIPAA and GDPR-compliant service providers. Kang emphasizes that when Mira and Oura began designing this partnership, the question wasn't technical—how to move data between systems—but human: how do we help women understand their own lives better? The answer, it turns out, is to stop treating hormones as isolated lab results and start treating them as part of the continuous story your body is telling.
Notable Quotes
Hormones have traditionally been treated as something you measure in isolation—maybe once, in a clinical setting. But that's never how women actually experience their bodies.— Sylvia Kang, Mira CEO
The question wasn't 'How do we integrate data?' but 'How do we help women understand their lives better?'— Sylvia Kang, Mira CEO
The Hearth Conversation Another angle on the story
Why does it matter that this is the first integration of clinical-grade hormone data into daily tracking? Couldn't women just check their hormone levels separately and correlate them themselves?
You could, but you'd be doing the work manually—checking a number from last Tuesday's test, then scrolling back through your sleep data to see if there's a pattern. The integration does that work for you, and more importantly, it normalizes the idea that hormones aren't a separate thing you measure once. They're part of your daily reality.
The CEO mentions that hormones shape how you sleep, your energy, your mood. But aren't all those things already tracked by Oura?
Yes, but Oura was showing you the effect without the cause. You'd see your sleep score drop, but not know why. Now you can see that your progesterone was low that night, which actually explains the poor sleep. It's the difference between a symptom and understanding what's driving it.
Who benefits most from this? Is it just people trying to get pregnant?
Fertility tracking is one use, but it's broader. Anyone going through perimenopause or menopause—which can last years and feel completely destabilizing—suddenly has data to make sense of it. And even people with regular cycles benefit from understanding how their hormones affect their energy and mood day to day. It's about agency.
The privacy language is pretty careful here. Why does that matter in this context?
Because you're sharing intimate biological data—urine samples, hormone levels, sleep patterns, all of it. The fact that Mira explicitly says they don't sell it and only use anonymized data with compliant providers isn't just legal boilerplate. It's the foundation of whether women will actually trust the system enough to use it.
What happens next? Is this just Oura and Mira, or does this open the door to other integrations?
That's the real question. If this works—if women find it useful and the data actually helps them—you'll likely see other wellness platforms wanting to integrate hormone tracking. But it depends on whether Mira stays the only player with clinical-grade accuracy, or whether competitors emerge.
