A wearable sleep tracker that actively promotes better sleep and will track brain activity? Say hello to the Sleep Shepherd Blue. This headband helps you optimize your sleep patterns with a patent-pending biofeedback system using customized binaural beats and passive EEG measurements. In other words, wear it, fall asleep, get a good night’s rest.

Factoid: Sleeping leads to dreaming so here’s a wild fact about dreams; before color TV, 75% of people had black and white dreams. Now it’s down to 12%.
