The American company BrainCo, together with the Harvard Research Laboratory, has announced an innovative device called OxyZen. It promises to change the approach to managing psycho-emotional state. The stylish headband uses advanced technology to monitor brain waves, heart rate and blood oxygen levels, providing users with valuable recommendations for relaxation and improved sleep. The device connects to a mobile app. It provides access to more than 600 meditation programs ranging in length from a few minutes to half an hour. Depending on the user's current state, the app adapts the workouts, including posture and breathing exercises that promote overall recovery and stress reduction. In addition, OxyZen offers a sleep mode in which the device plays soothing nature sounds. Throughout the night, the bezel collects data on brain activity, allowing users to track their sleep quality and receive recommendations on how to improve it. The OxyZen is currently available for pre-order at a price of $299. The bezel comes with a charger, sensor, and storage bag. The first shipments are expected in December
