Wearable Boosts Sleep Quality


San Francisco- and Paris-based neurotechnology company Rythm has created a wearable device that uses sound to improve the quality of sleep.

The headband, called Dreem, monitors and analyses the brain's electrical activity in real time with electroencephalography (EEG) sensors. When the wearer enters a state of deep sleep, the device transmits sound that gently stimulates the brain to stay in this slow-wave stage for an extended period. Research shows that people who remain in a deep sleep for longer benefit from improved cognitive and physical performance the following day, according to the creators.

Dreem can also wake the wearer at their optimal sleep stage, as close to a specified time as possible, helping avoid the grogginess associated with being woken during an unsuitable phase.

An accompanying app provides details on when sound was triggered and how much more deep sleep this allowed the user, together with visual insights showing various stages of slumber throughout the night. A limited number of the wearable headbands will be available from June 2016, priced at $349 each.

Consumers are increasingly keeping their entire bodies under surveillance to enhance mental and physical states, as detailed in CES 2016: Personal Electronics. They desire tech products that anticipate needs and proactively optimise wellbeing, with minimal effort on their part – see Wired Health 2015 and Digital Worlds Update: The Consumer of 2030 for more.
