Optical Heart Rate: A Leap in Accuracy and Comfort

Heart rate monitoring is essential for any runner or athlete. With Polar Elixir, this measurement reaches new standards of accuracy thanks to the latest generation of optical heart rate (OHR) sensors. This technology uses light to measure changes in neo flow under the skin, providing real-time readings of your heart rate during exercise, sleep and everyday activities.

The optical sensor, redesigned to minimize interference from movement, ensures more accurate readings even during intense workouts. This means you can trust the data you get, ensuring you're training in the right heart rate zone to reach your goals without putting your health at risk.

Electrocardiogram on the wrist

Polar has taken heart monitoring one step further with the integration of electrocardiogram (ECG) at the wrist. Traditionally, an ECG required specialized equipment and multiple electrodes attached to the body. Now, with Polar Elixir technology, you can get an accurate ECG reading directly from your wrist by simply placing a finger on the watch button for 30 seconds.

This wrist-based electrocardiogram provides you with information about your heart's electrical activity, including average heart rate, heart rate variability (HRV) and successive beat intervals (RR). These metrics are essential for understanding how your body adapts to training, how it recovers and how it handles stress. Through the Polar Flow app, you can follow your ECG history, analyze trends and share the results with your coach or even a doctor, if you wish.

Skin Temperature

Another innovative feature of Polar Elixir is nighttime skin temperature monitoring. This feature allows you to automatically record your skin temperature while you sleep, providing valuable information about your overall health. Skin temperature is a sensitive indicator that can reflect changes in your well-being, such as fever, inflammation or even menstrual cycle phases in women.

Core body temperature remains stable at around 37 °C, but skin temperature, especially at the wrist, can vary between 33 and 37 °C in a healthy adult. Polar Elixir measures your skin temperature every five minutes during the night and gives you a daily comparison with your average for the last 28 days. This information helps you identify any abnormalities that may suggest a change in your health status, allowing you to take preventive measures or adjust your training accordingly.

The development of Polar Elixir is based on years of research and Polar 's accumulated experience in biosensor technology. Since the creation of the first wireless heart rate monitor, Polar has been at the forefront of accurately measuring health and performance. With Elixir?, they have succeeded in integrating multiple advanced technologies into a single device, offering users a powerful and easy-to-use tool.

The optical heart rate sensor has been optimized to reduce motion interference, making it one of the most accurate available on the market. This is especially important for athletes who need reliable data to adjust their training and improve their performance.

Wrist ECG offers a level of detail that was previously only available in a clinical setting. Now, you can access this information at any time, allowing you to make informed decisions about your training and recovery.

Nightly skin temperature, measured continuously during sleep, gives you a comprehensive view of your well-being, helping you detect subtle changes in your body before they become major problems.

Practical applications of Polar Elixir in your everyday training

Polar Elixir technology isn't just for elite athletes; it's designed for anyone who wants to improve their health and performance. Here's how you can integrate these features into your daily routine:

Continuous Monitoring: use the optical heart rate feature to make sure you're training in the right zone. This is crucial to maximize the benefits of each session and avoid overtraining.

Wellness tracking: Perform a wrist ECG regularly to monitor how your heart responds to exercise and stressors. This will allow you to adjust your training as needed and ensure your body is recovering properly.

Health check: Take advantage of nightly skin temperature monitoring to detect possible signs of illness or inflammation. If you notice a significant increase in your skin temperature, it could be a sign that your body is fighting something, and you may need to adjust your training or get more rest.

If you're looking to take your training to the next level and want total control over your health, Polar Elixir and Polar Grit X2 Pro are the tools you need. Not only will you be using the most advanced technology available, but you'll also be investing in your long-term wellness.
