...everything. There's an ad in the New York Times today for a "Personal Sleep Coach." Zeo promises to increase your ZQ so you can sleep better and get the most out of your day.
What in God's name is a ZQ?
ZQ is a single number that objectively measures the quality of your sleep. Your ZQ is calculated by measuring the total amount of time that you slept (total Z), and adding and subtracting points based on the amount of restorative sleep (deep and REM) and disruptive sleep (time and duration spent awake) that you get throughout the night.
Huh?
Whatever. Only in America, right?
