The Thim Sleep-Tracking Ring is a wearable device that’s shown to work. In fact, this ring can even extend the amount of time you spend asleep at night, thus helping you feel rested in the morning. Furthermore, it not only helps you fall asleep faster but also wake fewer times in the night. There’s almost nothing worse than a bad night’s sleep, and this sleep tracker can help ensure you never experience one again. When you’re getting ready for bedtime, simply place this sleep-tracking wearable on any finger. Once you’ve fallen asleep, Thim wakes you with a gentle vibration. This act of waking actually helps you fall asleep better over time. It might seem counterintuitive but just think of it like sleep training for adults.
