The watch helps to improve the quality of your sleep by measuring and evaluating which part of your sleep is light, deep and REM sleep. Based on Unidata, you get tips and instructions for improving the quality of your sleep. The new sleep coaching program has reliable tracking features to help you improve your sleeping habits. Your personal sleep rhythm will be monitored for 7 days, and you will be helped to find your own totem animal. With the help of a month-long coaching program, you will develop your sleeping habits and recovery. Thanks to the built-in sensor (IHRN, Irregular Heart Rhythm Notification), the watch monitors your heart rate in the background and notifies you if your heart rate has been irregular for a long time. That way, you know when it's time to take an ECG measurement that gives you more information about your heart rate. Stay in the right heart rate zone and get the best results. The watches of the Galaxy Watch6 series monitor your heart rate so that you train at the level of exertion that corresponds to your goal, from warm-up to maximum performance.
