![]() ![]() This is because the majority of people experience bad sleep as a result of poor sleep habits - either they're not getting enough sleep or they're not being consistent with their bedtime," explains Dr. ![]() "Most people don't need a sleep study to understand why they're not getting quality sleep. ![]() While these metrics might not sound all that flashy, this information can be very beneficial for identifying factors that lead to poor sleep. However, what most wearable devices are pretty reliable at measuring inclides: when you went to sleep, when you woke up and the total time you spent asleep. Sawal says that time spent in various stages of sleep isn't likely to be very accurate, either. With this imperfect science in mind, you may want to be particularly wary of the more complex metrics, such as sleep quality, sleep scores or readiness ratings. A lot of extrapolation has to happen between collecting those measurements and providing an assessment of your sleep," says Dr. "First and foremost, it's important to understand that the data collected by wearable sleep trackers are very indirect measurements of your sleep. Sawal.Ī sleep study, also called a polysomnogram, is the benchmark of assessing sleep, and it is what experts rely on to analyze a person's sleep patterns and identify what's causing sleep disturbances. ![]() You can show your doctor the sleep data your tracker provides, and your doctor may certainly use this data to determine whether you might benefit from undergoing a sleep study, but the data is not comprehensive or reliable enough to diagnose a sleep disorder," says Dr. "If you're concerned about your sleep, discuss your concerns with your doctor. Meaning, it cannot be used to diagnose sleep apnea, insomnia, narcolepsy or any other sleep disorder. The most important thing to know about tracking your sleep via your smart watch or a comparable device is that the information provided isn't clinical in nature. Sleep trackers can't detect sleep apnea or diagnose other sleep disorders Speaking of your sleep dashboard, when it's in the red more often that not, you may start to wonder whether you have a sleep disorder.or if your sleep tracker just isn't accurate. These measurements are then processed through algorithms and neatly bundled into (sometimes confusing) panels of dashboards that help you understand your sleep.Įach particular device's sleep dashboard looks different, but the metrics generally include: "The movement information is used to determine whether you're asleep or awake, as well as whether your sleep is restful or restless." "The heart rate measurements are used to try to infer which stage of sleep you're in at a given time," explains Dr. While each wearable device varies slightly, the two primary measurements being collected all night are your movement and your heart rate. Most wearable devices that track sleep devote quite a bit of battery power to assessing it. This doesn't mean tracking your sleep is a waste of time, but it does help to know what you can and can't rely on when it comes to sleep metrics and wearable devices. Ali Sawal, primary care practitioner at Houston Methodist. On the other hand, many of these devices provide a lot of information - much of which may not be very accurate - without helping you actually turn this data into better sleep," explains Dr. Having a grasp on your sleep habits can be the first step toward improving your sleep. "Tracking sleep via a smart watch or wearable device is becoming more and more popular. Given how elusive a good night's rest seems to be for many of us, it's only natural to look for ways to better our sleep.īut, when considering whether you should be tracking your sleep, what you're probably really wondering is: Are sleep trackers actually accurate? In fact, a recent poll conducted by the National Sleep Foundation (NSF) found that almost half of us feel sleepy at least three days a week. Still, many of us feel perpetually tired. We all know that getting plenty of sleep is important. ![]()
