My Fitbit gives me a sleep report which includes “deep sleep”. I wonder if that is equivalent to what they are talking about.
Also, it would have been nice if they had said how much deep sleep is normal and how much is required.
The article is too sketchy to be useful.
Just got a fitbit. It says I get very little deep sleep. But then it consistently gives my poor sleep for less than my hour goals high marks even though I’m awake 10x a night according to the data it is tracking.
It’s my first fitbit-type device and I’m pretty skeptical of everything except maybe the heart rate. And the app is typical garbage written by modern marketing morons. I’m hoping against hope that they hired decent hardware guys to design the device itself before handing the app off to the millenial soy brigade.
Apologies for the grumpiness. I’m old enough to remember when devices that were pathetic by modern standards still had interfaces that were light years ahead of anything produced today in terms of usability despite being built with rudimentary or even no development tools. Hardly anything today seems to be designed with function in mind, but it shoar is purty.
