These days, there are far more accurate sleep trackers on the market. Some brands, like Eight, have them incorporated into the mattress. But you can also buy trackers that you put under your bed or on your bedside table, like S+ by ResMed, Emfit, and Beddit. I used one called Sleeptracker that works with any mattress on the market, collecting data on a phone app.

I was impressed by how sensitive it was to my particular movements. If you sleep with a partner, you can get two devices that you insert under each side of the bed. And you can let it know if you have a pet–or 28 pound toddler–who makes occasional visits to your bed.


For the first time, I was able to identify the exact moment I fell asleep and when I was going into different phases of sleep. Rather than monitoring your movement, Sleeptracker identifies your breathing patterns and heart rate, since these markers change when you enter different sleep states. The app allowed me to move from measuring the quantity of time I was in bed to measuring the quality of my sleep.

Every morning, I get some important data points.  I get a figure about my sleep efficiency, which is the percentage of time I was actually asleep. I also receive my sleep score, which is Sleeptracker’s measure of my overall quality of sleep, including how much REM sleep I got. These are quick figures that allow me to see how well I am sleeping from one night to the next.

This was life-changing for me. I discovered that when I had more efficient sleep, I could be in bed for a shorter amount of time, but still feel extremely well rested. This means that I have more hours in my day to work and hang out with my family. Empowered with real data, I am able to pinpoint what is actually disrupting my sleep, rather than just speculating. I discovered that my sleep score goes down when I go to bed anxious or angry, so I do a mental check before bed and do breathing exercises if I am worked up about something. Drinking more than one glass of wine at dinner lowers my score, so now I watch how much I’m consuming.

For years, I assumed that if I was asleep for eight hours of more, I would wake  up well-rested. After a full night of sleep, if I somehow felt tired or crabby, I assumed there was something else wrong, like I was hungry or that other people were being mean to me. I don’t need to hypothesize any more. There are nights when I’ve been in bed for nine hours, but it wasn’t efficient sleep, so I am able to mentally prepare myself for a tougher day ahead — or cut myself some slack. But perhaps most importantly, I can learn why I slept so poorly and change my behavior to make sure it happens less often.
