Deep Sleep May Be the Best Defense Against Alzheimer’s

Your skepticism is justified. Oura publish their data, and to quote them:

>Oura ring was 96% accurate in detecting sleep compared to polysomnography, 48% accurate in detecting wakefulness, 65% agreement in detecting “light sleep,” 51% agreement in detecting “deep sleep” and 61% agreement in detecting REM

So it's basically wrong with sleep categorization about half the time.

oura ring hardware is horribly limited in terms of precision. let it not be a barrier to invest in a good wrist/arm/head band
