A popular question is how do sleep trackers work, but there’s more to them than meets the eye. These devices can also measure heart rate. This is much more accurate than measuring motion alone. Other types of trackers use scientists’ estimates of sleep stages to determine whether or not you’re sleeping. Regardless of how they’re marketed, the fact is that they’re not a replacement for a professional sleep study.
Many sleep trackers use actigraphy to measure the duration of sleep. This measurement is helpful for patients with insomnia. However, many people underestimate their sleep duration, making it difficult to get the desired amount of restful sleep. A tracker’s accuracy is better when you’re sleeping, but errors become more apparent if you’re disrupted. So it’s important to be consistent with the duration of your sleep before using a sleep tracker.
A sleep tracker works by detecting changes in your heart rate and movement. This information is used to help physicians monitor your heart rate and identify underlying health issues. Some models can also measure changes in your breathing and sleep stage. Ultimately, the technology should provide a more accurate diagnosis of your sleep. There are many different types of sleep trackers on the market today. To understand which one suits your needs best, consider the features of each one.
