Sleep devices are tools that are used to assist the user in understanding individual sleep patterns with the objective of improving sleep and optimizing daytime performance, or treating sleep problems such as sleep disorders. Some of these sleep gadgets are worn on the user during sleep. Some are placed on the bed stand.
In this section, we review these sleep monitoring devices, sleep wearables, sleep trackers and apps and other sleep gadgets, show how they work, and get feedback from users. Users will rate sleep technologies to rank the best sleep gadgets.
Most of the sleep monitoring technologies work by using sensors on a device to collect information about the sleeper and summarize the input.
Historically, sleep was monitored (and still is monitored), in a sleep center performing a sleep study. During a traditional sleep study, the patient or research subject is attached to dozens of wires and electrodes. They are strategically placed on the body to measure specific biologic rhythms, including: brain waves, eye movements, breathing, muscle tone, heart rhythm, blood-oxygen saturation, and snoring. These signals are sent to a polysomnograph which records the data. The data is processed by a sleep technologist and then sent to a sleep physician for interpretation.
With improvements and miniaturization of technology, what was once the size of a refrigerator can now be placed in the palm of a hand. Some sleep gadgets have their own proprietary sensors. Some sleep-tracking technologies are app-based (sleep apps and snoring apps.)
Many of these new tools use microphones, motion sensors, and cameras to monitor the sleeper. Some use temperature sensors and light sensors. Some newer sleep wearables utilize electrodes and other sensors that are attached to the body.

How much do sleep devices cost? Most of the devices listed above cost between $100 - $200. Most of the apps are a few dollars.
Are sleep monitoring devices safe?
Generally, these devices are safe. There is a potential danger that the user will mask or underdiagnose a potentially dangerous sleep disorder
Which is the best sleep tracker and sleep wearable?
There is little data assessing practical efficacy with this category of technology.
There are several physician-prescribed devices used for the treatment of sleep disorders. Most of the devices mentioned here are for the treatment of obstructive sleep apnea. However, there are devices used for other sleep disorders.
As technology evolves, more and better sleep devices will come to market with the objective of helping people sleep better. Please contact us with your stories of how sleep devices have helped you.
