No device, regardless of how sophisticated it is, will solve serious sleep issues. But if you’re looking for more information about how you sleep, monitoring patterns can be illuminating, reports The New York Times.
Still, sleep scientists say a lot of people go to sleep at night and wake up tired for reasons they can’t explain. If you live alone, you might have no idea that you have sleep apnea, restless legs or even problems like sleepwalking. Sleep tracking can help uncover patterns that you didn’t already know about, even if they are not always completely accurate.
“A given night might not be completely accurate, but if the person looks at the trend over time it might be more revealing,” said Dr. Clete A. Kushida, medical director at the Stanford Center for Sleep Sciences and Medicine.
