Your fancy sleep tracker is no match for a dedicated sleep lab.But who wants to spend 8 hours in a strange hospital room wired withelectrodeswhile some video records you all night?Now,we may have a solution:high-tech sleep-monitoring headbands that combine brainwave-reading electrodes with sophisticated artificial intelligence.And best of all,they can be worn in your own bed.

“The technology could make it easier to get accurate readings of someone's sleep patterns at home,”says Tristan Bekinschtein,a neuroscientist at the University of Cambridge in the United Kingdom.As is shown in sleep lab studies,the headband also tracks head movement,heart rate,andrespiration,relying on sound recordings like those found in smart phones.Built-in artificial intelligence analyzes the data,identifying whether a person is,for example,in rapid eye movement sleep or other known stages like non-rapid eye movement sleep,which are not as deep.A prime benefit,he says,is that they get rid of the wires thatinhibitmovement during sleep and they can be used over multiple nights.

Sleep studies normally require a trained technician to read,record,and analyze traditional sleep study data,Bekinschtein notes,but the Dreem headband collects data and wirelessly transmits them to a smart phone.He says the device is useful because the people involved in his studies are more comfortable than in a traditional sleep lab and can be observed over many nights,providing better data.Still,he says the information collected by the headband is not a replacement,but rather a means of collecting data to help diagnose sleep disorders.

Bekinschtein predicts sleep labs will use such devices more and more as the technology progresses.“Ultimately,I'm excited about all of these products that are coming along,”says Nathaniel Watson,a neurologist and sleep specialist at the University of Washington in Seattle who also uses the new sleep monitors in his lab.“They're really improving our understanding of human sleep.”
