"The Oura Ring does several things, but its bread and butter is sleep and vitals tracking. It uses the data it monitors, including a person's heart rate, heart rate variability, body temperature, and breathing rate, to create daily scores for a user's sleep, readiness, and activity. It also tracks daytime stress, specifically how often a person's heart rate exceeds a relaxed state, and cumulative stress, which measures the long-term impact of that aforementioned daytime stress on a person's ability to recover."
"It's so good I have even told my own mother, one of the more critical people I know, to buy one for herself. The main reasons boil down to its sleep tracking, wealth of data insights, and illustration, and general tendency to alert you of possible illness or strain, thanks to its intelligent predictive algorithm. I have made several positive changes to my daily routine and have become aware of my less healthy habits thanks to the Oura Ring."
The Oura Ring 4 Titanium tracks sleep and multiple vitals, using heart rate, heart rate variability, body temperature, and breathing rate to generate daily sleep, readiness, and activity scores. The device monitors daytime stress and cumulative stress, measuring how often heart rate exceeds a relaxed state and the long-term impact on recovery. A predictive algorithm highlights possible illness or physiological strain and provides extensive data insights that can prompt behavior changes. The ring costs $350 with an optional $70 annual subscription for full access. The device is on sale during Black Friday, presenting a timely buying opportunity.
