COUNTING SLEEP

摘要

THE BEST WAY TO MEASURE SLEEP QUALITY IS IN A LAB, with a dozen or so sensors stuck to your noggin and torso. The 6-inch-tall SleepScore Max tracker ($150) can't replace a trip to the clinic, but it can give you data about your slumber without even touching you. Plus, it monitors conditions like light, sound, and temperature to perfect your bedroom setup.
