New technology offers a plethora of opportunities for individuals to monitor their sleeping habits and quality. Sleep trackers record sleep data primarily through accelerometers, devices that measure discreet movements, and biometrics during slumber. Data from the accelerometer then goes into a general algorithm that estimates the quality and duration of sleep. Unfortunately, while these numbers can give a general picture of sleep health, they are not personalized, and results should be taken with a grain of salt.
