Oura ring : What’s the ring for?

The Oura ring is enjoying growing success in the market for devices that track body signals (sleep, activity, stress and cardiovascular health). With growing awareness of the importance of sleep to overall health, more and more people are turning to these devices to monitor and improve their sleep habits.

What is the Oura ring?

The Oura ring is a health and sleep tracking device worn on the finger, designed to provide continuous and detailed monitoring of physiological parameters. Developed by Oura Health, the ring uses advanced technology to provide accurate data on sleep, physical activity and general health.

The Oura ring was initially launched in 2015 by Oura Health, a Finnish health technology company. The concept for the ring arose from the need for a health monitoring tool that was both accurate and non-intrusive. Over the years, the Oura ring has evolved through regular hardware and software updates, incorporating the latest technological advances in sensors and analysis algorithms.

How does the Oura ring work?

The Oura ring is a concentrate of technology, incorporating several sophisticated sensors to monitor and analyse various physiological parameters. These sensors include heart rate sensors, body temperature sensors and accelerometers, which collect data continuously. This information is then processed by advanced algorithms to provide a detailed analysis of sleep cycles, activity levels and vital signs. Here’s a detailed look at the Oura ring’s main functions:

Sleep tracking

The Oura ring excels at sleep tracking thanks to its advanced sensors and sophisticated algorithms. It measures the different stages of sleep, including :

• Light sleep: Transitional phase between wakefulness and deeper sleep.
• Deep sleep: Essential phase for physical recovery and memory consolidation.
• REM sleep: Phase characterised by rapid eye movements, associated with dream activity and cognitive restoration.

In addition to sleep stages, the ring detects micro-awakenings, providing a complete picture of sleep quality. The data collected can be used to calculate important metrics such as :

• Total sleep time: Total time spent sleeping during the night.
• Sleep efficiency: Percentage of time spent sleeping in relation to total time spent in bed.
• Time spent in each sleep stage: Distribution of the different sleep phases during the night.

This information helps users to understand and improve their sleep habits.

Tracking physical activity

As well as tracking sleep, the Oura ring also monitors daily physical activity. Built-in motion sensors track :

• Number of steps: Calculates the number of steps taken throughout the day.
• Distance covered: Measures the total distance covered.
• Calories burned: Estimates calories burned as a function of physical activity.

The ring can also detect periods of inactivity and encourage the user to get moving to avoid a sedentary lifestyle. This function is particularly useful for maintaining regular, balanced physical activity.

General health monitoring

The Oura ring goes beyond simply tracking sleep and physical activity by monitoring vital signs that are crucial for assessing general health:

• Resting heart rate: Measures heart rate when the body is at rest, an important indicator of fitness and stress.
• Heart rate variability (HRV ): An indicator of cardiovascular health and stress levels. A high HRV is generally a sign of good health.
• Body temperature: Monitoring of temperature variations to detect potential abnormalities, such as early signs of infection or stress.

The data collected by the ring is analysed to detect early signs of stress or illness, enabling the user to take proactive steps to maintain or improve their health.

All the data collected by the Oura ring is synchronised with a dedicated mobile application. This application provides an intuitive user interface that presents information in a clear and detailed way. Users can view their sleep, physical activity and general health data, and receive personalised recommendations to improve their overall wellbeing. The app’s algorithms analyse trends and patterns in the data, providing valuable insights and advice for optimising health and performance.

What are the benefits of the Oura ring?

The Oura ring has several advantages over other health tracking devices:

• Accurate measurements: Thanks to its high-quality sensors and advanced algorithms, the Oura ring provides accurate and reliable measurements of physiological parameters.
• Comfort and design: Designed to be discreet and elegant, the Oura ring is comfortable to wear at all times. Its lightweight, robust design means it can be used continuously without discomfort.
• Battery life: The Oura ring has a long-life battery that can operate for several days without frequent recharging, making it ideal for continuous, uninterrupted use.
• Personalisation and recommendations: The Oura mobile app analyses the data collected and provides personalised recommendations to improve sleep and overall wellbeing. These recommendations are based on the user’s sleep patterns, activity levels and vital signs.
