Next, you’ll need to wear the monitor while you’re awake. This allows you to track your heart rate throughout the day. Afterwards, you’ll need to analyze the data. This involves looking at trends in your heart rate and comparing them to other people.

This information can help you identify areas where you may need to improve your lifestyle habits. You can also use the data to compare yourself to others. This helps you see whether you’re healthier than average.

Finally, you can use the information to set goals. This includes things like improving your diet, exercising more, and sleeping better. Once you set your goals, you can track the results.
