Remember a while back when I shared that I purchased a Jawbone Up? Well, after a few weeks of wearing it (on and off), I’ve found it’s pretty awesome. It’s a wrist bracelet that tracks my steps per day and the amount of sleep I get, breaking it down into “light” versus “deep” sleep. More than anything, I’m fascinated by the amount of sleep I get. For me, sleep is invaluable. It’s a huge health priority for me and I know that I only function well with 7-9 hours of sleep a night.

Here’s what the sleep graph on Jawbone Up looks like. (And no, I don’t sleep 10 hours a night regularly! This was one of my post-flight, jet-lag nights of sleep. But man, a night of 10 hours sleep feels really good.)

What’s cool about Jawbone Up is that they give you little facts about how you compare to other people in your same demographic. I’m not sure if you can read the text in the above right image, but it says that I get “1 hr 20min more Sound sleep than other women in their 30s. They average 3 hr 13min of Sound sleep per night.” But that was not an average night for me. Usually, I average about 7 and a half hours a night. It was cool to see how that particular night of sleep compares to other women my age.

So how much sleep should a 30-something get? Looks like the scientific advice is 7-9 hours per night, according to this article on Slate. In addition, I’ve read that you should try and learn how to fall asleep within 30 minutes of laying down. Not sure exactly how one goes about doing that, but creating a sleep ritual is a nice idea.

To happy and healthy sleeping in 2015!
