What is the Muse sleep device and how does it work?

The Muse sleep device, simply known as Muse S (Sleep), is a multi-sensor meditation and sleep headband designed to assist individuals in falling asleep more easily and improving the quality of their rest. It works by providing real-time feedback on a user's mental activity through EEG-based neurofeedback, as well as tracking heart rate, breath, and body movements during sleep. The device offers guided meditations and biofeedback exercises that help users relax by promoting mindfulness and assisting in the transition from wakefulness to sleep. Via an accompanying app, users can access a variety of soundscapes designed to respond to their changing mental states, thus creating a personalized experience that encourages relaxation and facilitates better sleep hygiene.
