What You'll Learn

Alta HR's heart rate sensor is used for sleep tracking
The Alta HR is a sleek fitness tracker from Fitbit, designed for those who want to monitor their health and fitness without compromising on style. The Alta HR is Fitbit's slimmest tracker with a heart rate monitor, making it a less clunky option for those who like to wear their tracker everywhere. The Alta HR's heart rate sensor is used for sleep tracking, making it more useful in this department than its predecessor, the Alta.
The Alta HR's heart rate sensor is used in combination with accelerometer data to track when the wearer is in light, deep, or REM sleep. For example, when in REM sleep, the heart rate is variable, but the body is still. By combining its sensors, the Alta HR can identify the different phases of sleep. This information is displayed in the companion app as a chart, showing how the wearer moves between the three modes of sleep each night.
The Alta HR's sleep tracking feature is called Sleep Stages, and it shows what type of sleep takes place over a given night and how long that type of sleep lasts. The categories include awake, REM sleep, light sleep, and deep sleep. This information can help users make better choices about their sleep habits and improve their overall health. The Sleep Stages feature is also available on the Fitbit Charge 2 and the Fitbit Blaze.
The Alta HR's heart rate sensor is designed to be more accurate than that of the Alta, with a sample rate for heart rate readings every five seconds, providing useful insights for those interested in day-to-day wellness tracking. The Alta HR's band has also been updated with a buckle at the end, ensuring a more secure fit on the wrist, which is important for accurate sleep tracking.

Alta HR's Sleep Stages dashboard shows the type and duration of sleep
The Alta HR is a great option for those who want to track their activities, heart rate, and sleep. The device is a slim wristband with a buckle at the end, making it more secure and comfortable for sleep tracking. It is also one of the most accurate and insightful sleep trackers on the market.
The Alta HR's Sleep Stages dashboard is a new software feature that provides detailed information about the type and duration of sleep. This includes the four categories of sleep: awake, REM sleep, light sleep, and deep sleep. The dashboard shows how much time is spent in each category, allowing users to understand their sleep patterns and make improvements. For example, a user might discover that they wake up frequently for brief periods during the night.
The Sleep Stages feature works by combining the heart rate data with movement data from the accelerometer. This allows the Alta HR to estimate the sleep stage the user is currently in, recognising that the body goes through different phases during the night. The data is presented in a line graph, making it easy to understand how the user moves between each phase of sleep throughout the night.
The Sleep Insights feature complements Sleep Stages by using the data to recommend ways to improve sleep quality. While some users may find that the insights are not as personalised or useful as expected, they can become more tailored as more data is logged over time. Overall, the Alta HR's Sleep Stages dashboard is a valuable tool for anyone wanting to understand and optimise their sleep.
