How we test products
Our mission is to take the guesswork out of finding the perfect sleep products.
We've dedicated hundreds of hours to testing mattresses and sleep accessories, and rely on a team of testers of differing weights, temperature preferences, and sleeping positions to evaluate each product.
Tested products are granted the Sleep Hero tested stamp of approval, a mark of our review's reliability.
If we haven't personally tested a product, please be assured that we invest significant time and energy into scouring the UK market and researching the best recommendations, and we work with a team of sleep experts who review our articles, ensuring that the insights we provide are not only relatable but also reliable.
What is the Oura Ring?
The Oura Ring is a tiny titanium device that records data to give a clearer picture of your wellbeing. 🧘♀️
The ring is usually worn on the index, middle or ring finger and can be worn all day–similar to a wedding ring.
The smart ring connects to your phone via Bluetooth where you can track your progress on the Oura app or other fitness apps.
The Oura Ring comes in a simple design and is available in 4 colours.
- Stealth (dark grey)
The Oura Ring weighs 4 to 6 grams (depending on the ring size), making it an exceptionally light piece of technology.
Who is the Oura Ring for?
The Oura Ring 3 is an excellent choice for anyone wanting to better their sleep or general health. ✅
We recommend this product to:
- Tech-savvy smartphone users
- Those looking to track fitness, health, and sleep all at once
- Those who have tried smartwatches and not got on with them
If you’re into fitness, then this activity tracker can help you analyse your workout routine, as well as rest and recovery periods. 😌
Since this little piece of tech requires downloading an app, we wouldn't recommend it to those who don't own a smartphone. ❌
What can the Oura Ring tell me about my health?
The Oura Ring isn't just about aiming for a good score.
This nifty titanium ring can help bring other health concerns to light. 😮
So, what can it help with?
Unlike the earlier generation of Oura Ring, the Oura Ring Gen 3 can track your heart rate throughout the day. 🩺
This is useful, particularly for those who want to receive readings on their heart rate during and after their workout.
It also means you can monitor how other lifestyle choices affect your heart rate, such as drinking coffee or taking certain medications. 💊
The Oura Ring Gen 3 also checks heart rate variability (HRV). 📈
This is the regularity (or irregularity) of the time between pulses, with a high HRV being the ideal.
A low HRV could indicate your body being under stress, which can help you make decisions about certain lifestyle choices.
The Oura Ring Gen 3 is equipped with 7 temperature sensors. 🌡
Unlike other smart wearables, the Oura Ring can monitor your body temperature minute by minute.
This direct contact with the skin from your finger allows the Oura Ring to follow temperature changes and make accurate readings.
An increase in body temperature can indicate the onset of an illness. 🤒
Obviously, changes in the day such as excessive exercise or weather will affect your body's temperature.
You should analyse the data using common sense, and the Oura Ring will not be able to diagnose temperature changes with the same accuracy as a doctor.
Your body temperature readings can also give you insight into your menstrual cycle. 🤔
This is particularly useful for those trying to have a baby who needs to monitor their monthly cycle.
As your temperature decreases during the first half of your cycle, and increases in the second half, you can follow the patterns to identify when you are due to menstruate and ovulate.
Some women have also noticed temperature increases to indicate a pregnancy. 🤰
You can learn more about how Oura Ring monitors menstruation on their FAQ page.
Is the Oura Ring comfortable?
If you're not used to smart jewellery - or any jewellery for that matter, you may have concerns about comfort.
The Oura Ring is fairly chunky when compared with the average wedding ring . . .
However, it has a simple design and is very lightweight 4 to 6 grams (depending on your chosen size.)
Most users found that they quickly adjusted to wearing the Oura Ring without any trouble.
However, if you're not keen on wearing any smart gadget, why not try sleep apps that don't require wearable items, such as the Emma Sleep Aurora app.
Oura Ring sizes
Oura recommends ordering their free sizing kit to ensure you get the correct Oura Ring size.
This should arrive within 2 - 7 days, and you can try the sample rings to figure out which size is best for you.
Oura Ring sizes are between 6 - 13 mm.
Are Oura Ring sizes standard?
Oura Ring sizes are unique and slightly different from standard UK ring sizes.
Therefore, it's crucial to ensure you order the correct size ring.
The best way to do this is by ordering an Oura Ring sizing kit and testing the sizing ring for a few days. ⏳
Rotate your sizing ring for 24 hours to ensure it isn't too tight for when your finger expands.
How tight should my Oura Ring be?
First, you should decide which finger to wear your Oura Smart Ring on, although Oura recommends the index finger for best results.
The ring should fit securely and snugly without gaps between your finger and the ring.
However, you should ensure it's not too tight. 😯

Before you order your sizing kit, you should also ensure the Oura Smart ring is within your budget.
Oura Ring discount codes
You've heard of a five-finger discount, but can you expect any Oura Ring sales when shopping for this nifty gadget? 🤑
You can get as much as 55% off with an Oura Ring discount code, particularly around seasonal periods.

What are the pros of the Oura Ring?
However, the Oura Ring 3 is unique in that most wearables come in watch form, whilst the Oura is a more discreet choice.
The longer battery life also means you don’t have to charge up every time you want to track your sleep. 🔋
Some also prefer that the Oura Smart Ring is “less annoying” to smartwatches, as it doesn’t give you constant notifications relating to your health. 📴
As the Oura Ring doesn’t give you access to other apps and social media, it can also help you steer clear of the temptation to be constantly plugged in.
