Aaron Hartman, MD explains what actually matters in sleep tracking: REM and deep sleep, not just hours in bed. Monitor breathing for pauses and oxygen levels, since drops can signal sleep apnea.

So actually knowing the time you're in bed, how much is actually being asleep is super huge. But the most important part of your sleep at night is that REM and deep sleep, which you can measure with these appliances or apps. The other thing you can look is you watch your breathing. Like, how are you breathing? Are you stopping breathing at night? The app, the current one I use, actually measures disordered breathing and you can actually look at your oxygen level to see if your oxygen level drops. Those can be markers of disordered breathing and sleep apnea. If you're sleeping adequately, you won't have a lot of disruptions in your sleep and your oxygen level won't drop.
