The key is not to accumulate metrics, but to identify trends that allow adjust habits and discuss more information with a professional.

These devices usually measure heart rate and variabilitysleep, activity, steps, effort and recovery. Some add skin temperature o oxygen saturation. None replaces a medical consultation nor does it convert an isolated reading into a diagnosis: its greatest value is to observe the data evolution for weeks and detect variations in usual values.

The choice should prioritize comfort, autonomy and ease of use rather than a long list of functions. The sensors They are located on the inside of the band, in contact with the skin, and record data silently and continuously.
