Self-Knowledge and the Wearable Tracker: Caroline Kryder, of Oura Ring, Explains

What are the benefits of wearable trackers and how do they work? What is heart rate variability (HRV)? How do trackers understand when we’re in light sleep, deep sleep, or REM sleep? What is the optimal time spent for each sleep cycle? What does the future for wearable trackers look like?

Wearable trackers take the guesswork out of our health. Instead of going off of a feeling, you can now get personalized data on what’s really going on; that’s why we are such big fans of trackers. Caroline Kryder, the Science Communications Lead at Oura Ring, joins us on the podcast to share all about wearable trackers from how they work to how we can use them to optimize our health. 

What you will learn in this episode:

  • How wearable trackers work
  • How wearable trackers provide highly personalized data to improve your health
  • The different sleep cycles
  • How sleep and rest help performance
  • What the future holds for wearable trackers

“You don’t get to self-care until you get to self-knowledge.”

“REM sleep is really focused on restoring the mind and deep sleep is really focused on restoring your body.”

“We’re used to using soreness as an indicator of an effective workout because that’s the only thing that you could feel. If you felt like you’d been hit by a bus, it was probably working. When in fact, there’s some training that you shouldn’t actually feel any muscle soreness.”
