Understanding Rem Sleep With Garmin: What Does It Mean?

REM stands for rapid eye movement and is the final stage of the sleep cycle. During this stage, your brain is almost as active as when you're awake and dreams occur. REM sleep is important for forming memories and processing information. Garmin's advanced sleep monitoring feature tracks and provides data for light sleep, deep sleep, and REM sleep. Previously, Garmin devices only tracked sleep and did not show REM sleep levels.

REM stands for Rapid Eye Movement sleep, which is the final stage of the sleep cycle

Garmin's Advanced Sleep Monitoring (ASM) uses an optical heart rate sensor to measure heart rate variability, which lets you know when you're in REM or non-REM sleep. Your heart rate is all over the place when you're in REM sleep, allowing your watch to differentiate between the two. The watch will get more accurate the more often you wear it because it will start to figure out what your heart rate is when you fall asleep. It will also use the accelerometer to track movement to account for any times that you get up in the middle of the night.

To ensure the most accurate sleep tracking, it is recommended that you put your watch on two hours before bed, wear it every night, and ensure that it is snug but comfortable on your wrist. If you own more than one Garmin, set the watch you want to wear at night as your preferred tracker in the Garmin Connect app.

The Garmin Connect app will provide you with data on your sleep cycles, including light sleep, deep sleep, and REM sleep. You will also get a movement timeline that shows how much you moved during your sleep. The app also provides a 7-day view of your sleep patterns, which can help you identify any changes in your routine that may be affecting your sleep.

Some Garmin watches also provide extra data such as a pulse oxygen timeline and respiration rate, which can help you spot any patterns or problems with your sleep. Compatible devices with Advanced Sleep Monitoring include the Forerunner 245 Series, Forerunner 645 Series, vivosmart 4, fenix 5 Plus series, Forerunner 245, and Forerunner 945.

Garmin's Advanced Sleep Monitoring (ASM) feature can track REM sleep

Garmins Advanced Sleep Monitoring (ASM) feature can track REM sleep

Garmin's Advanced Sleep Monitoring (ASM) is a feature that can track REM sleep. REM stands for Rapid Eye Movement, which is the last stage of the sleep cycle. REM sleep is important for forming memories and processing information. During this stage, the brain is almost as active as when one is awake.

Garmin's ASM feature uses optical heart rate sensors to measure heart rate variability, which helps the watch determine when one is in REM sleep. The variability of heart rate during REM sleep is high, which allows the watch to differentiate between REM and non-REM sleep.

To ensure accurate sleep tracking, Garmin recommends wearing the watch two hours before bedtime and keeping it on while sleeping. The watch should be snug but not tight, and it should be worn every night. Additionally, if one owns multiple Garmins, the watch worn at night should be set as the preferred activity tracker in the Garmin Connect app.

ASM is currently supported on several Garmin watches, including the Forerunner 245 and 645 series, vivoactive 3, vivomove HR, and vivosmart 3.

The Sleep Cycle

A normal night of sleep consists of light sleep, deep sleep, and REM sleep.

During the first stage of light sleep, eye movements and muscle activity slow down as the body prepares for deep sleep. This stage helps with relaxation.

The next stage is deep sleep, where eye and muscle movements stop, and heart rate and breathing slow down. This is the restoration mode, aiding in recovery, building bone and muscle, and boosting the immune system.

The sleep cycle ends with REM sleep, which occurs in short bursts that get longer as one leaves deep sleep. This is the dreaming stage, with brain activity almost matching that of wakefulness.

Sleep Data

Garmin's sleep tracking provides data on the previous night's sleep, including the duration of light, deep, and REM sleep, as well as awake time. This data is available in the Garmin Connect app.

The app also offers a seven-day view, showing averages for the different sleep stages and sleep duration over a week. This can help users identify patterns and make changes to their sleep routine for better consistency and health.

Some Garmin watches also provide extra data, such as pulse oxygen levels and respiration rates. This additional information can help users spot any potential issues and address them promptly.

Garmin's Advanced Sleep Monitoring (ASM) feature offers valuable insights into one's sleep patterns and quality. By tracking REM sleep and other stages of the sleep cycle, users can make informed decisions to improve their sleep habits and overall health.

The optical heart rate sensor in newer Garmin watches can measure heart rate variability, which helps the watch identify when you're in REM sleep

Garmin's advanced sleep monitoring function can track and provide data for light sleep, deep sleep, REM (rapid eye movement) sleep, and awake time throughout your evening. Previously, Garmin devices tracked sleep, but did not show REM sleep levels. REM sleep first occurs around 90 minutes after you fall asleep. Adults typically experience five to six REM stages each night, each one longer than the last. Dreams are common during REM sleep.

To ensure the most accurate sleep tracking, it is recommended that you put your watch on two hours before bed. This will give the watch heart rate data before you fall asleep, hopefully making it more accurate at determining when you fall asleep. In order to make sure the heart rate tracking is accurate, make sure the watch is snug on your wrist, but not tight. You don’t want to be uncomfortable when you sleep. Wear it every night to get into the habit. You’ll get inaccurate sleep data if you leave it charging overnight.

In addition to the accelerometer data that Garmin has been using for sleep tracking, it is using heart rate variability data from the optical HR sensor to provide REM sleep tracking with this update.

To ensure accurate sleep tracking, wear your watch at least two hours before bed and keep it on while you sleep

REM stands for "rapid eye movement" sleep, which is the final stage of the sleep cycle. This is the dreaming stage, when your brain is almost as active as when you're awake. REM sleep is important for forming memories and processing information.

To ensure accurate sleep tracking with your Garmin watch, it is recommended that you wear your watch at least two hours before bed and keep it on while you sleep. Here are some detailed instructions on how to do this effectively:

First, make sure your watch is set as your preferred activity tracker. This will ensure that your watch is the main device used to monitor your sleep, rather than your phone or any other connected devices. In the Garmin Connect app, go to Settings > User Settings and select your watch as the preferred tracker.

Next, ensure that your watch is snug on your wrist, but not too tight. You want it to be comfortable, as you'll be wearing it throughout the night. It should be secure enough that it won't move around, but not so tight that it's uncomfortable.

Then, about two hours before you plan to go to sleep, put your watch on. This will allow the watch to collect heart rate data before you fall asleep, which will help it more accurately determine when you fall asleep and when you wake up. Make sure you wear it every night to get into the habit. If you leave it charging overnight, you won't get accurate sleep data.

Additionally, make sure that your watch is set up with your usual sleeping hours. This will help the watch to start tracking your sleep at the right time. In the Garmin Connect app, go to Settings > User Settings and edit your Bed Time and Wake Time.

Finally, remember to keep your watch charged. If your watch battery dies in the middle of the night, you won't get a full picture of your sleep. Also, make sure that your app is up-to-date and that you have a valid birth date saved in the User Settings, as this information is necessary for accurate sleep tracking.

By following these steps, you can ensure that your Garmin watch accurately tracks your sleep, including the time spent in each stage of the sleep cycle: light sleep, deep sleep, and REM sleep. This information can help you develop good sleep habits, which are crucial for overall health and well-being.
