Holiday times are stressful — and not getting enough sleep can be a major setback for anyone. I've been promoting and working alongside the team of Mind Rocket to help improve users sleep through technology with the Sleep Shepherd Blue device ($200) and the results are impressive. Sleep Shepherd Blue helps you fall asleep by using soothing binaural tones — all inside a ultra comfy headband. Once you're asleep, it tracks and analyzes your sleep in real-time with brainwave sensors and biometric feedback. The device was created by Dr. Michael Larson to help his 17-year-old daughter who suffered from a sleep disorder.
