I let the new Oura Ring track me for a month — it revealed 3 major health gaps
The Evolution of the Oura Ring 4 Ceramic
The Oura Ring 4 Ceramic is a wearable that you’ll actually want to wear. It was designed with the intention of being more than just a fitness tracker — it’s a piece of jewelry that blends seamlessly into your daily life while offering deep health insights. After wearing it for a month, I found myself reluctant to take it off, as it has become an essential part of my wellness routine.
Key Features of the Oura Ring 4 Ceramic
- Material: The ceramic design is hypoallergenic and skin-friendly, making it a great alternative for people who are allergic to titanium.
- Color Options: The ring comes in four trendy shades: Midnight, Cloud, Tide, and Petal. These colors are infused into the material, which helps prevent fading and scratching over time.
- Software Update: A new software update allows users to swap between rings without losing data, providing greater flexibility in how you use the device.
- Durability: The ceramic material is known for its exceptional durability and lightweight comfort. It can be worn in saunas up to 125 degrees and underwater at depths of up to 100 meters.
- Battery Life: The ring holds 8 days of charge, so you rarely have to take it off.
What’s New with the Oura Ring 4 Ceramic?
While the ceramic model offers the same health tracking features and sensors as the titanium versions, it has a slightly heavier and chunkier feel compared to the titanium models. However, the ceramic design provides a more elevated, hypoallergenic option that is ideal for those with sensitive skin.
Pros and Cons of the Ceramic Model
Pros:
* Ceramic is hypoallergenic and skin-friendly
* Colors are infused into the material, preventing fading and scratching
* New software update allows for easy switching between rings
Cons:
* Slightly heavier and chunkier feel compared to titanium
* Same health tracking features as the titanium model
How Accurate Is the Oura Ring Health Data?
The Oura Ring 4 Ceramic collects data using recessed, interior sensors integrated around your index finger. These smart sensors automatically adapt to the unique structure and skin tone of each user’s finger to ensure highly accurate readings. A 2020 study revealed that the Oura Ring is about 99% accurate when testing Heart Rate (HR) and Heart Rate Variability (HRV) when compared to ECGs. Another trial from a top US hospital compared the Oura Ring to the Apple Watch and the Fitbit, finding that the Oura Ring had the highest sensitivity for deep sleep detection.
Where Should You Wear Your Oura Ring?
The Oura ring can be worn on any finger of either hand. Oura recommends choosing the index, middle, or ring fingers for the best signal quality. These fingers have larger blood vessels, which could help optimize photoplethysmogram (PPG) pulse monitoring. For the best fit and most accurate readings, the ring should be aligned so the sensors are against the palm side of the finger.
My Review of the Oura Ring 4 Ceramic
As a wellness writer, I’ve tested numerous wearables, but the Oura Ring felt like the obvious next step. Through testing, I found that many wearables excel at tracking the here and now, but fall short in identifying long-term patterns. The Oura Ring bridges this gap by providing real guidance that helps understand how daily choices affect long-term health.
Oura Ring Sizing
The Oura Ring Ceramic is available in sizes 4 through 15. The brand highly recommends ordering the sizing kit before picking a ring size. This free kit is available on the Oura website when you purchase a ring or can be purchased on Amazon for $10. Trying them on is simple; just place the desired plastic sizer on your chosen finger for at least 24 hours.
Oura Ring Set-up
The Oura Ring 4 Ceramic arrives in a compact white box with the ring itself, a guide to getting started, a circular charging dock, and a USB cable. The Quick Start Guide has simple instructions for getting set up. First, download the Oura Ring app, then pair your ring. The app will prompt you to enter some basic profile details, including your sex, weight, age, and height, which are used to help calibrate health readings.
Sleep Tracking
Forget scrolling on Instagram or TikTok, the real initiation into the Oura Ring cult is complete when you begin waking up and impulsively checking your sleep score before anything else. The Sleep Score is a comprehensive look at your rest, calculated from factors like total sleep, efficiency, REM, deep sleep, and latency. An 85 or higher is considered optimal.
Recovery and Stress
The Readiness Score is a holistic measurement that analyzes key biometrics like Heart Rate Variability (HRV), Resting Heart Rate (RHR), body temperature, and sleep quality. A high score indicates you are primed to take on the day, while a lower score is a gentle nudge to take it easy.
Activity and Cardiovascular Health
Oura allows you to set your own activity goal, and Step Progress is displayed front and center on your home page. Beyond basic movement and calorie burn, there is a lot more to uncover regarding your Activity Score. Oura tracks your Training Volume and Training Frequency, helping you diversify your training for better cardiovascular and metabolic health.
Symptoms Radar
Symptoms Radar uses biometrics like temperature, respiratory rate, and heart rate to catch early signs of physical strain or illness. This feature has alerted me twice, helping me avoid spreading illness to others.
Cycle Tracking and Women’s Health
The Oura Ring picks up on each phase of the menstrual cycle and provides information on how your body is impacted. This is helpful for women who want an estimate of when to expect their period or for those looking to get pregnant or avoid pregnancy.
Multi-Ring Support Feature
Alongside the launch of the Oura Ring 4 Ceramic, Oura introduced a new Multi-Ring Support feature. This allows users to pair multiple Oura Rings to a single account, perfect for changing up your look with a different ring.
Final Verdict: Is the Oura Ring 4 Ceramic Worth It?
For anyone with sensitive skin or a titanium allergy, the ceramic option is the best choice, even with the $150 upcharge. If titanium doesn’t bother you, the standard version offers better value. Either way, the Oura Ring 4 is a sound investment for anyone who cares about their health. It detects daily shifts and long-term trends that meaningfully affect your life. In my experience, it uncovered hidden cardiovascular insights, flagged illnesses before I felt symptoms, and exposed everyday stressors I had overlooked.
How We Tested
After testing the Oura Ring 4 Ceramic for a month, I evaluated it across several key areas: comfort and style, health data and trends, Oura health insights, and the overall user experience. The ring provided accurate data, actionable insights, and a seamless user experience.
