It did say how long I was on the log but the results did not match the time spent sleeping or show the early part of my sleep. I have tried setting a sleep log when I go to bed turning it on when I retire and off when I wake. I know I’m a restless sleeper, but I can’t get any accurate account of my night when I know I was in bed at 10pm and may have taken a short time to fall asleep and that I was in some type of sleep mode for the next couple of hours but my results say I only want to sleep at 3 or 4 am. By using the heart rate it says they wait 3 hrs to determine your sleep pattern, well that 3 hours is not included in the result and in my case I may wake up before that 3 hr period is complete. I have Charge2 and don’t really think it gives as accurate time of sleep as the cheaper version my daughter has. Ready to get started?

Plus restless sleep isn’t necessarily a bad thing - studies show it’s common for adults to wake up briefly between 10 and 30 times per night.

Sleep stages combines the time you spend awake and restless into total awake minutes.

If you notice more awake minutes in sleep stages than in your previous sleep data, don’t worry. “Some people may even have a prolonged awaking at that point.” “Every 70 to 90 minutes when you transition out of REM and back to stage 1, you hit a fragile point where you might have a brief awakening,” says Fitbit sleep consultant Allison Siebern, PhD, consulting assistant professor at The Stanford Center for Sleep Sciences and Medicine and director of Sleep Health Integrative Program at the Veterans Affairs Medical Center in Fayetteville, NC. In addition to detecting your sleep stages, adding heart rate to the mix also allows your tracker to better pick up on restlessness and short periods of wakefulness that you may not even remember. The result? A way to differentiate between light, deep, and REM sleep that doesn’t require multiple sensors, cords, and an expensive stay in a sleep lab. When you sync your tracker in the morning, your device will use the heart-rate-variability and movement data it gathered during the prior night to estimate your sleep cycles. You’ve probably heard that your heart rate slows when you fall asleep, but did you know that it doesn’t stay steady throughout the night? Research shows that heart rate variability- beat-to-beat changes in your heart rate-fluctuates as you transition between light, deep, and REM sleep.įitbit Alta HR, Fitbit Charge 2, and Fitbit Blaze continuously monitor your heart rate variability along with your heart rate. So what’s that second signal? Here’s a hint: It’s something many Fitbit trackers can already track-heart rate! Heart Rate During Sleep Stages “You need something else that is going on in the body that differentiates REM from other stages of sleep.” “You need another signal,” says Grandner. In other words, you can’t determine light or deep sleep based on movement alone. “Except during REM sleep when doctors are also looking for eye movements and a lack of muscle activity.” But in order to determine your sleep stages -how long you spend in light, deep, and Rapid Eye Movement (REM) sleep-movement alone is not enough.ĭuring sleep studies, “most sleep stages are scored based on brain waves,” says Michael Grandner, MD, director of the Sleep and Health Research Program at the University of Arizona in Tucson and a Fitbit sleep consultant. If you’ve been using a Fitbit tracker to monitor your sleep, then you know how important movement is to signaling when you fall asleep, wake up, or stir.
