LOS ANGELES - Huge Mercier has just the cure for your poor sleep--a headband you wear to bed, to improve your sleep.
The $399 Dreem sleepwear, available in June, contains bluetooth and wifi, but you're not connected while in bed. Instead, you pick up information on the companion app when you awake. During the sleep process, the five sensors from the device records your brain waves and triggers sound Mercier says will help you sleep.
Making a precise sound, at a precise moment, can sync with your brain waves to stimulate deep sleep, he says.
But can this really work? We're skeptical. Watch the video above to see why.
