Jawbones and Fitbits are fine, but there are still some health insights that your own brain figures out better
Jawbones and Fitbits are fine, but there are still some health insights that your own brain figures out better. Like this one: How did you sleep last night? In a recent Reddit AMA, Ying-Hui Fui, a sleep scientist at the University of California, San Francisco, explained that while wearables do a good job of measuring movement and heart rate while you sleep, they aren’t going to provide an accurate picture of the quality of your night’s rest.
“To really know the quality of sleep, we have to be able to measure EEG during sleep,” said Fui, meaning the brain’s electrical activity. “Most EEG devices are difficult to use and expensive.” In other words, they don’t retail for $99 and clip neatly to your clothing. The best way to track your own sleep, then, is the old-fashioned way, Fui said. More on that:
You still know yourself better than your Fitbit does.
