Ihr Gesundheits-Tracker weiß, dass Sie nicht gut geschlafen haben. Hilft das – oder schadet es?

It’s become a competition.

Every morning my husband and I wake up and compare our sleep scores: his from a Samsung watch and mine from an Oura Ring 4. We either congratulate whichever one of us performed “best” that night, or we curse our choice to stay up late binge-watching Netflix.

I’d asked for an Oura for my 36th birthday in October. I was starting to worry more about my health and thought a wearable device would motivate me to get more exercise and sleep after a decade starting work at 4 a.m. in a high-stress TV newsroom.

To me the ring is motivational, largely because I have that millennial personality trait of needing to get all A’s on my report card. I’ve found myself going on walks at lunchtime to get an activity score in the 90s—the Oura gives scores out of 100—and swapping Champagne for seltzer at parties because I realized alcohol tanked my sleep stats. (Except for a notable exception on New Year’s Eve, which made my ring and those of many Reddit users [upset with them on New Year’s Day](https://www.reddit.com/r/ouraring/comments/1q13z0j/how_mad_is_your_oura_ring_today/)).

I’m far from alone in obsessing over these metrics. Health‑tracking devices have been taking over our fingers and wrists, offering information on everything from steps to sleep to hormonal health to heart-rate variability, a marker of fitness and stress resilience.

IT can sell this data as „anonymized“ info to advertisers. So right from the wake up I can be exposed to most ads of products that will most effectively extract value from me, based on my mental and physical form.

Looks fine to me, what do you think?
