In the last nine years, I’ve reviewed nearly 1,000 products for The New York Times. Can you guess what every single one of them has had in common?

All of them were intended for use while you’re awake.

Today, the exception.

Studies show that about half of all Americans don’t get the recommended amount of sleep. (For adults it’s seven to nine hours.) And as we stumble our way through each day, groggy and cranky, we pay a terrible price in our relationships, productivity and health.

Science has learned all kinds of things about sleep. We now know, for example, that during the night, we experience several cycles of different kinds of sleep. There’s REM (rapid eye-movement) sleep, which restores and refreshes our brains. There’s deep sleep, which restores and refreshes our muscles. There’s light sleep, which is better than nothing. And there are all those times we wake up but don’t even remember we slept.

Now, to find out why you feel so wretched in the morning, you could go to a sleep lab, pay thousands of dollars, and spend the night hooked up to wires and sensors. Or you could pay $400 and get yourself a Zeo alarm clock.

That’s expensive, sure, but this one does a few things your basic Wal-Mart

It comes with an elastic headband, which you’re supposed to wear to bed each night. In its center, resting against the skin of your forehead, there’s a little transmitter pod, something like a digital watch without the band. All night long, this thing measures your brainwaves and transmits them wirelessly to the clock on your nightstand.

When you wake, you put the headband back onto its charging shelf on the clock. The screen comes to life, showing you a very cool graph of your night.

You can walk through it using arrow keys. The clock, and the graph, indicate where you were at each five-minute interval: awake, in light sleep, in REM sleep or in deep sleep. You can also step through screens that display your sleep-cycle tallies in huge digital numbers: “2:54 REM,” “0:35 deep” and so on.

Everything is polished and easy to use, from the way the headband snaps magnetically onto its charging shelf to the way the alarms themselves (music or nature sounds) slowly grow louder the longer you ignore them. If you like, the alarm can try to wake you where you’re sleeping lightly, to prevent the grogginess that comes from being awakened from a deep sleep. (It will never wake you later than the time you’ve set; you specify how much earlier you’re willing to accept.)

And it’s truly amazing, if not a little creepy, to see all of this data about a part of your existence that you’ve known nothing about until now.

But as my wife said, “If I wake up and feel lousy, I don’t need a $400 gadget to tell me it’s because I didn’t sleep well.”

Ah, but that’s where the coaching comes in.

The Zeo stores your sleep records on a memory card. As often as you can, you’re supposed to pop it out and insert it into a U.S.B. card reader (also included) on your computer. At this point, you can go to MyZeo.com and upload your data to the Web.

Now the real fun begins. This Web site lets you slice, dice and cross-compare your sleep data in a million ways.

It starts with a bar chart of your nightly sleep scores. This number (your ZQ, as the company cutely calls it) is a single convenient score that takes into account both the negatives (like disruptions) and the positives (REM and deep sleep). During the month I wore the Zeo, my average was about 70, which is typical for middle-agers like me.

My highest was 105. That was for a luscious 10-hour sleep after an all-nighter.

But you can go much deeper with your statistics. You can plot the quality of your sleep, or one type of sleep, over time, by week or month. Or plot these characteristics against each other, looking for cause and effect. See whether your bedtime affects how long you sleep, whether you get more deep sleep on weekends, whether caffeine in the afternoon affects the number of times you wake up in the night, and so on.

Weirdly, the Zeo system completely ignores exercise. There’s no way to report how much you exercised on a given day, to see if it affects your sleep. (Hint: It does. A lot.)
