In the Fitbit line, a few of the recently updated trackers include the ability to monitor the wearer’s sleep patterns. We just tried out the Fitbit Alta HR that offered this same feature.
Fitbit worked with independent polysomnography technicians to see whether or not their trackers can actually measure sleep in a meaningful way. It turns out that, yes, they work, and that could provide some benefits to consumers.
The gist is that the trackers can be used “to track sleep stages with a reasonable degree of accuracy in normal adult sleepers, avoiding the cost and artificial sleep environment of a sleep laboratory.” That last bit is the big point, quite honestly.
In the piece I wrote that I linked above, I posed a question: why would you want to track your sleep in a meaningful way? Well, with word that this works with “a reasonable degree of accuracy,” it’s much cheaper to simply buy and wear a Fitbit than it is to get the work done by a sleep lab.
That might not affect you, but it would affect someone who isn’t covered by insurance and suffers from problematic sleep.
This is good news for Fitbit, and it’s a unique use for wearable tech.
