Sana Sleep looks like padded goggles, or a pared down and comfy version of a VR headset. It is being tested currently with athletes in training who want the most restorative sleep they can get while traveling extensively. The goggles emit pulses of light and sound. The wearer is conscious of the lights and sounds at the outset of each use, but becomes less aware of these as they drift off to sleep. The goggles measure things like a users’s pulse and breathing, and customizes the signals in response to the individual’s biometrics.
