Can't fall asleep? Your mind won't stop racing? Drift uses the science-backed Cognitive Shuffle method to help you fall asleep faster โ no meditation, no breathing exercises, just words. How it works: Simply tap Start, close your eyes, and listen. Drift whispers random, unconnected words to your mind โ breaking the cycle of anxious thoughts and guiding your brain into sleep. Based on research by cognitive scientist Dr. Luc Beaudoin, the Cognitive Shuffle technique mimics the natural thought patterns of sleep onset, helping your brain transition from wakefulness to rest. โ Zero setup โ open and sleep โ 8 languages โ English, Spanish, Portuguese, German, Russian, Chinese, Arabic, Turkish โ Alphabet mode โ engage your mind gently โ Adjustable word speed โ 4 to 15 seconds โ Auto sleep timer โ 15, 30, or 60 minutes โ Fades out automatically when timer ends
