 Not getting enough sleep can affect you in more ways than you might expect, as Yael and Don discuss in this Moment of Science.   Y: Today, on a Moment of Science, we're conducting an experiment on sleep deprivation 1. On my right, we have my friend Bob, who hasn't slept in eighty-eight hours straight! Bob? Bob? Okay, so he's pretty unresponsive. And on my left, we have Don, who has been restricted to no more than four hours of sleep a night for the past two weeks. How are you feeling, Don?


D: (YAWNS) Well, I'm a little tired, Yael, but not as tired as Bob over there, who I think is drooling.
Y: If you've ever relied on a doctor or an airplane pilot, then you know there's a lot at stake over whether Don is telling the truth about how tired he feels.
D: Of course I'm telling the truth. I feel fine (YAWNS).
Y: Well, you might think you feel fine, but I have in front of me the result of the cognitive 2 performance tests both you and Bob over here took earlier today. And guess what?! Don! Don!
D: Huh? What?
Y: These cognitive performance tests show that you and Bob are having equal trouble performing some pretty basic tasks.
D: But Bob hasn't slept in three days!
Y: Exactly. So that means that even missing only a couple of hours of sleep a night really adds up if you do it every night. In other words, sleep debt is cumulative 3, and right now, you have no more business going out there and driving a car than Bob does. What's more, you're so tired right now that you can't even properly evaluate how tired you are, which makes your sleep debt even more dangerous.
D: Guess I better catch up on some Zs! (BOB SNORES)Y: Looks like Bob's beaten you to it.
