Dreem has released a biofeedback headband with seven sensors that work together to measure key biomarkers, including brain activity (EEG), heart rate, breathing and movement. The system works with a smartphone app to guide users toward improved sleep, the company announced this week.

The device, called the Dreem 2, is now available directly to consumers looking to improve their sleep and to healthcare providers looking for a new solution to propose to their patients. The data collected by the headband is used in-app 7-week program, which includes exercises, tools and advice designed to help the user.

“This is the first step in our mission to deliver precision sleep medicine at scale. With the US launch of our FDA-registered medical device, we’ve taken our place at the forefront of sleep healthcare,” Vik Panda, Dreem’s managing director for North America, says in a statement.

Dreem 2 aims to address sleep problems, including difficulty falling asleep, staying asleep or waking up too early.

“Poor sleep has a tremendous impact on productivity, stress, absenteeism and overall mental health, not to mention the link between poor sleep and a long list of chronic diseases. Our first-of- its-kind solution helps individuals take control of their sleep, thereby improving their overall health,” says Panda.

Since the company’s founding in 2014, it has raised $60 million from investors including Johnson & Johnson and put together a team of 90, split across New York, Paris and Taipei. Dreem has also collaborated with academic institutions and hospitals across the world, including Stanford Sleep Center, and has created a scientific advisory board of sleep physicians and neuroscientists.
