You have been lied to about sleep your entire life. Eight hours. That is the number they drilled into your head. Get your eight hours. Anything less and you are damaging your brain, wrecking your metabolism, shaving years off your life. So you dutifully climb into bed, set your alarm for eight hours later, and wait for the magic to happen.

Except it does not happen. You wake up groggy. You drag yourself through the morning. By 2 PM, you are fantasizing about crawling under your desk for a nap. And the cruel joke is that you did everything right. You gave sleep eight hours, sometimes nine. You bought the expensive mattress. You downloaded the sleep tracking app. And still, you feel like you got hit by a truck.
