I USE A FITNESS TRACKER TO MONITOR MY SLEEP BUT AM NOT SURE WHAT I DO WITH THE DATA.
You’ve just hit on one of the biggest problems in the sleep-tracking world. Ready for two more? Not all trackers are accurate, and they don’t all agree when it comes to standard definitions of certain terms like “deep sleep.”
But let’s assume your tracker is accurate—what next? First, you’ll want to put your data in context by comparing it with the data of other people of your gender and age. If you’re a 38-year-old female, you want to know what your data looks like relative to the average woman your age.
Next, you’ll want insight into improvements you can make for peak sleep performance. This would require a real-time advice engine that would give you information based on your previous night’s sleep and lead you to personalized sleep goals. The only tracking system I’ve found that does this reliably is the Sleepscore Max (sleepscore.com, $150). The company also recently released a free app that uses your smartphone to track and analyze your sleep as well.
