Monitoring Your Rem Sleep: A Comprehensive Guide

Sleep is a vital part of our lives, and getting a good night's rest is essential for our health and well-being. Tracking your sleep can be a great way to understand your sleep patterns and identify any areas for improvement. REM sleep is a crucial stage of sleep, and tracking it can provide insights into your sleep quality and duration. With advancements in technology, there are now various ways to track your REM sleep and overall sleep health. From wearable devices like smartwatches and fitness trackers to phone apps and dedicated sleep sensors, you can gain valuable insights into your sleep habits and make informed decisions to improve your sleep hygiene.

Wearable devices, such as smartwatches and fitness trackers

When choosing a wearable sleep tracker, it is important to consider comfort and ease of use. Look for a device that is lightweight, compact, and unobtrusive so that it does not interfere with your sleep. Some devices have silicone bands, while others have knit bands or fabric straps. You may also want to consider the charging method and battery life, as you will need to recharge the device regularly.

Oura Ring 4

The Oura Ring 4 is a competitive sleep tracker that offers insights into sleep efficiency, restfulness, readiness, latency, and more. It has smart sensors for more accurate and continuous data capture and is more comfortable than its predecessor, the Oura Ring 3. The ring provides a sleep score and suggests a bedtime range based on your data. It also has a feature that teaches you about your circadian rhythms and body clock. The battery life is advertised as eight days, but some users have found it to be closer to five to six days. The Oura Ring requires a paid subscription to access all the data it collects.

Apple Watch Series 10

The Apple Watch Series 10 is a great option for Apple users who want to integrate their sleep data with their iPhone. It offers sleep cycle tracking and has FDA-cleared sleep apnea detection. You can set sleep goals and use the Sleep Focus mode to limit distractions before bed. However, it does not provide a sleep score or summary. The battery life is shorter than other wearables, lasting up to 18 hours.

Google Pixel Watch 2

The Google Pixel Watch 2 is a good choice for Android users. It has improved heart rate sensors and integrates Fitbit's sleep tracking technology, including nightly trends, a silent alarm, bedtime reminders, and sleep goals. The watch is lightweight and comfortable for sleep, but it has a limited 24-hour battery life.

Garmin Venu 3S

The Garmin Venu 3S is a good option for athletes and fitness enthusiasts. It has a sleep coach feature that provides a sleep score and tracks sleep stages, naps, heart rate variability, and skin temperature. The battery life is impressive, lasting up to 10 days, but sleep tracking can drain the battery quickly.

Whoop 4.0

The Whoop 4.0 is a lightweight, screenless band that tracks your sleep and provides a personalized sleep coach. It measures four sleep stages and suggests optimal sleep times. It also has a feature that calculates how much sleep you need based on your daily activities. The Whoop app provides detailed sleep trends and data plots. However, it requires an annual membership subscription.

These are just a few examples of the many wearable sleep trackers available on the market. Each device has its own unique features, so you can choose the one that best suits your needs and preferences.

Phone apps, like SleepScore and Sleep Cycle

SleepScore, for example, provides detailed tracking of your sleep, including how long it takes you to doze off and the time spent in light, deep, and REM sleep. The app also asks you to set sleep goals and provides suggestions on how to improve your sleep habits. For a premium subscription, you get more in-depth reports and personalized suggestions from sleep experts.

Sleep Cycle is another popular app that gives you access to a wealth of information about your sleeping habits. It can track your periods of wakefulness, light sleep, and deep sleep, which you can then measure over time. It also has a smart alarm clock feature that wakes you up during a lighter period of sleep within a preset time window. For a small monthly fee, you can access additional features such as data export and the ability to link other information like coffee consumption and exercise to your sleep patterns.

Under-mattress sensors, like the Withings Sleep mat

The Withings Sleep mat provides advanced sleep tracking and analysis, including sleep cycle analysis (deep, light, and REM sleep), heart rate tracking, and snore detection. It offers a daily Sleep Score, which breaks down your night into six meaningful indicators with colour-coded feedback, helping you identify areas of your sleep that can be improved. You can also track the number of snoring episodes and their durations and learn more about snoring patterns and what may affect them.

The mat connects to your phone via Bluetooth and the Withings Health Mate app (available on iOS and Android) to provide you with a daily sleep report. The app is user-friendly and allows you to easily share your sleep data with your doctor or other healthcare providers. The Withings Sleep mat also integrates with other smart home devices, allowing you to control lights, temperature, and other smart home-enabled devices just by getting in and out of bed.

The Withings Sleep mat is a popular choice for those who want a simple and unobtrusive way to track their sleep. It provides valuable insights into your sleep patterns and overall sleep quality without the need for wearable devices. With its advanced features and compatibility with various mattresses, the Withings Sleep mat is a great option for anyone looking to improve their sleep.

Smart mattresses, such as the Eight Sleep Mars+

The smart cover connects to a Wi-Fi-enabled hub, and you can access your sleep data through the Eight app, which is available for both iOS and Android. The app provides a daily sleep score out of 100 and includes charts that show your sleep stages and changes in your heart rate and breathing. The Eight app also offers helpful sleep tools such as a Smart Alarm, which wakes you up during light sleep, and short meditation exercises and white noise for a more restful night.

In addition to sleep tracking, the Mars+ offers temperature control with dual-zone heating, allowing you and your partner to adjust the temperature on your side of the bed independently. The mattress itself is made up of three layers of foam and a layer of sleeved coils, providing a comfortable and supportive sleeping surface.

The Eight Sleep Mars+ is a good option for those who want to track their sleep without wearing a device 24/7. While it provides valuable insights into your sleep patterns, it is important to note that sleep tracking technology may not always be completely accurate, and the data should be used as a guide rather than exact scientific information.

In-bed trackers, like the iFit Sleep HR

If you're looking for a sleep tracker that doesn't involve wearing a device to bed, then in-bed trackers like the iFit Sleep HR could be a good option. This tracker lives under your mattress and provides a wealth of data about your sleep. The iFit Sleep HR disc is about the size of a small plate and is designed to be placed under your mattress around the area where your outer shoulder will rest. It can be used with any mattress size and thickness of up to 20 inches.

The iFit Sleep HR tracks a range of sleep metrics, including average heart and respiratory rates, how long it took you to fall asleep, how many times you woke up, and the duration of each sleep cycle, including light, deep, and REM sleep. The system generates a total sleep score for the night, which is tracked over time and can be viewed on a graph. The tracker also has a "smart" alarm feature that wakes you up during the lightest part of your sleep cycle, making it easier to get out of bed.

The iFit Sleep HR has a journal feature in its companion app for iOS and Android. This feature tracks your pre-sleep habits, such as whether you consumed alcohol or caffeine, had a heavy meal, or exercised. By monitoring and improving your pre-sleep habits, you can work towards raising your sleep score over time. The iFit Sleep HR is a great choice if you're looking for a dedicated sleep-tracking device that doesn't require wearing anything on your wrist.
