This Oura Ring review for women over 40 comes down to one answer: the Oura Ring is a good sleep and recovery tracker if you will pay for the Membership, and it is not a workout tracker or a medical device. I’m Judy. I’m not a doctor, and I haven’t worn this ring, so everything below comes from Oura’s own product page, a few studies I read and linked, and the limits those studies state.

Oura is a smart ring that tracks sleep, heart rate and activity, and its newest model is the Oura Ring 5. It sits in the smart ring type of wearable, so if you are still choosing between a ring, a watch and a chest strap, start with my guide to the best fitness trackers and wearables for women.

Table of Contents

What is the Oura Ring and what does it track?

The Oura Ring is a titanium smart ring that you wear around the clock and read in the Oura app. Oura’s Ring 5 page says it works with iOS and Android, is waterproof up to 100 m and is IP68 rated. It lists red and infrared LEDs for blood oxygen, green and infrared LEDs for heart rate, heart rate variability and respiration rate, a temperature sensor for temperature trends and an accelerometer for movement.

Oura groups that data into sleep, activity, readiness, stress, heart health and women’s health views inside the app. Oura’s site also still sells the Oura Ring 4, which Oura rates at 5 to 8 days of battery life, so check which model you are looking at before you compare reviews. Many older reviews were written about the Gen 3, an older model.

How much does the Oura Ring cost?

The ring costs $399 in silver or black and $499 in gold, deep rose, stealth or brushed silver, as listed on Oura’s Ring 5 page when I read it in October 2026. Prices change, so check the page before you buy.

The Membership is a second cost. Oura’s Membership page lists $5.99 a month or $69.99 a year for US members, with the first month free. Oura says that without a Membership the ring works only with limited functionality, so plan on paying for both. Over two years, the yearly plan adds about $140 to the ring.

How accurate is the Oura Ring for sleep tracking?

Accuracy is good for telling sleep from wake and weaker for sleep stages, and Oura describes the ring as non-diagnostic. A 2026 systematic review of finger-worn devices compared them with sleep lab polysomnography across 28 studies covering sleep staging and sleep apnea. In the sleep staging studies, which mostly enrolled healthy people, pooled accuracy was 0.87 for sleep versus wake (7 studies), but only 0.65 for light sleep, 0.81 for deep sleep and 0.74 for REM sleep (5 studies each). The rings reviewed were mostly older models, including Oura Gen 1 to 3, and most studies had a high or unclear risk of bias. The authors concluded these devices should not replace polysomnography for detailed sleep architecture.

A 75 person validation study tested 11 consumer sleep trackers against a sleep lab, including the Oura Ring 3 and the Apple Watch 8. Agreement varied a lot from device to device, with the best macro F1 score at 0.69 and the lowest at 0.26 (the extremes were two bedside apps, not the ring or watch). That study used the older Oura Ring 3, so it does not score the Ring 5. Treat your sleep stages as a rough trend, not a lab result.

Can the Oura Ring help with perimenopause symptoms?

It can record patterns such as sleep and nighttime temperature, but it cannot tell you that you are in perimenopause, and the research on it in women your age is limited. MedlinePlus says the menopause transition usually begins in your 40s and can bring hot flashes, night sweats and trouble sleeping.

The closest study is a 2022 Oura Ring study in healthy women. It followed 26 women with regular cycles, average age about 24, for one menstrual cycle. Sleep skin temperature was higher in the mid and late luteal phases than during menses. The authors note the small, not very diverse sample and call for future research in perimenopausal women, who were not studied.

Oura has also published its own perimenopause report from aggregate data on more than 100,000 female members, and its perimenopause article states that the ring is not a medical device and not intended to diagnose, treat, cure, monitor or prevent medical conditions. That is Oura describing its own data. If hot flashes or sleep problems are bothering you, bring your notes to your clinician and let them decide what is going on.

Does the Oura Ring help you lose weight?

Not on its own. A ring only measures; it does not change what you eat or how you move. What it can do is show your sleep, and one short trial suggests sleeping longer can lower how much people eat.

In a randomized trial of sleep extension, 80 adults with overweight who normally slept under 6.5 hours were coached to sleep longer. Their sleep rose by about 1.2 hours a night, and their energy intake fell by 270 calories a day compared with the control group. The average age was about 30, about half were men, the sleep extension lasted 2 weeks, and sleep was measured with a wrist activity monitor, not a ring. It does not show the same result for women over 40.

If you are weighing a prescription weight loss treatment, that is a decision to make with a clinician. A ring is not a substitute for that conversation.

What does the Oura Ring not do?

It does not diagnose anything, and it costs more to run than most trackers. Oura’s own perimenopause article calls the ring not a medical device. A few other limits apply:

Its full insights depend on the Membership, and the ring has limited functionality without it.
Battery life is a range. Oura lists up to 6 to 9 days for the Ring 5, depending on ring size and usage, and says capacity declines over time.
Heart rate comes from optical sensors, and the 2022 women’s study notes that photoplethysmography may be less accurate for darker skin tones.
If you want a chest strap level heart rate signal for training, see our guide to the best heart rate monitor for exercise.

Oura Ring vs Apple Watch for sleep tracking

The main difference I can support is battery. Apple’s comparison page lists up to 18 hours of normal use for the Apple Watch SE 3 and up to 24 hours for the Series 11, tested while paired with an iPhone, and both list sleep tracking and a sleep score. Oura lists 6 to 9 days for the Ring 5, so a ring is easier to wear overnight without a charging gap.

None of the studies linked here names one of them the winner for sleep accuracy. The 11 tracker study above included the Oura Ring 3 and the Apple Watch 8 and found wide variation between devices, so pick on comfort, battery and budget.

Who should buy the Oura Ring, and who should skip it?

Buy it if sleep and recovery are what you want to understand, you dislike wearing a watch to bed and the Membership fits your budget. It also suits you if you already have a watch for workouts and want a second, quieter sensor.

Skip it if you want workout coaching, a screen, or the cheapest option. A basic tracker costs less, and if your main goal is more daily movement a free app may be enough. Also skip it if you cannot wear a ring at work or in daily tasks.

Where can you buy the Oura Ring?

You can buy it from Oura directly, and Oura rings are also listed on Amazon. See Oura rings on Amazon. The results page I opened showed Oura Ring Gen3 and Ring 5 listings, so choose your model and size carefully. Sizing matters because Oura says each ring size has its own charger and battery life depends on size.

Medical note: I’m not a medical professional, and this page is general information, not medical advice. A ring cannot diagnose sleep apnea, a heart problem or menopause. If you have symptoms, a heart condition or take medication, ask your clinician before you act on any number from a wearable.

Frequently Asked Questions

Does the Oura Ring require a subscription?

Oura says the ring works with limited functionality without a Membership, and the Membership lists $5.99 a month or $69.99 a year for US members, with the first month free. Check the current price on Oura’s page.

How long does the Oura Ring battery last?

Oura lists up to 6 to 9 days for the Oura Ring 5 and 5 to 8 days for the Ring 4, depending on ring size and usage. Oura’s support page says the ring takes 20 to 80 minutes to charge and that battery capacity declines over time.

Which finger should you wear the Oura Ring on?

Oura’s support FAQ says it can be worn on any finger of either hand, and it recommends the index, middle or ring finger for the best signal.

Does the Oura Ring track heart rate?

Yes. Oura’s Ring 5 page lists green and infrared LEDs that measure heart rate and heart rate variability around the clock. If you train in heart rate zones, the heart rate monitor guide linked above covers other options.

Is the Oura Ring worth it for women over 40?

It is worth it if you want long term sleep and recovery trends and accept the ring plus Membership cost. It is not worth it if you want workout data or a diagnosis, because the studies show sleep stages are approximate and the one women’s study did not include perimenopausal women.
