Research shows that sound can enhance sleep, but only if applied at the right moment. The Dreem Headband uses sensors and smarts to make your night's rest even better. By analyzing your brain waves using advanced algorithms, it can play sounds at just the right time to make your deep sleep more restful, helping you to feel better when it's time to wake up. The system also uses AI to give you tips to improve your habits for even better sleep. And since none of this is helpful if you don't want to wear it, the Yves Behar design promises all-night comfort in any position.
