There are various factors involved that are essential to evaluate the sleep problems such as brain waves, breathing, heart rate and rhythm, muscle activity, the position of sleep, movement of eyes and much more.


Wearable sleep trackers are based on a technology known as actigraphy. It involves recording movement through a device called an accelerometer. Actigraphy is a less expensive and more comfortable way of assessing sleep problems. It does not cause any hurdles during sound sleeping, thus making the person sleep without any disturbance.

There are other non-wearable trackers such as mattresses that work with the technology embedded inside them. Several layers of mattresses are fixed with some of these basic equipment thus performing the same function as wearable ones.

Several drawbacks are mentioned, and technology developers must take care of it in future so that a more accurate presentation of facts is stated. These home-based technologies can’t be compared to clinical tests in terms of accuracy, but certainly, they are the best alternative and do not deviate much from the actual results.
