You didn’t know THIS About Sleep Trackers
00:00:00.000 | I have a lot of people coming my way
00:00:01.760 | and they're freaking out.
00:00:03.200 | I'm not getting any deep sleep.
00:00:04.920 | I'm not getting any REM, et cetera.
00:00:07.240 | Usually the application nowadays is that we're tracking
00:00:10.440 | with some sort of element of a sleep tracker.
00:00:13.520 | The problem is, is that this is the least accurate data
00:00:17.560 | on our wearables.
00:00:18.960 | It's using its own algorithm within each wearable
00:00:22.200 | to make its best guess on, are you in deep sleep?
00:00:25.800 | Are you in REM?
00:00:26.720 | Are you in light sleep?
00:00:27.760 | And the problem is, is that because it's that best guess,
00:00:32.760 | if the algorithm is changed,
00:00:34.480 | your results with your sleep staging
00:00:36.440 | is going to be markedly shifted.
00:00:38.360 | So my big message for people, if they are tracking,
00:00:41.040 | is one, to not get too crazed about the REM deep sleep
00:00:46.040 | and your light sleep.
00:00:47.720 | Instead, you can look from a trends perspective
00:00:50.560 | within each wearable.
00:00:52.240 | You can start to notice particular trends
00:00:54.560 | and see are there patterns that you can help support
00:00:58.040 | based on those trends.
