Using a smartwatch daily to track wellness data (physical activity, sleep) allows one to effectively adapt their exercise and health routine.

Using smartwatches to optimize lifestyle habits is an approach widely supported by wellness research. Regarding movement, an umbrella review (meta-analysis of reviews) published in *Sports Medicine* (Gianola et al., 2024) confirms that wearing an activity tracker significantly helps to increase daily step counts and reduce sedentary time. For rest, a comparative validation study (observational evidence) published in *JMIR mHealth and uHealth* (Lee et al., 2023) shows that consumer trackers are useful allies for assessing the regularity and total duration of our nights. However, this same study notes that the precise estimation of recovery phases (deep or light sleep) remains highly variable compared to laboratory reference measurements. Furthermore, a systematic review (research synthesis) published in the *Journal of Clinical Sleep Medicine* points out that excessive attention paid to our sleep scores can paradoxically generate stress related to the evaluation of our rest. In summary, using this data to adjust one's activity routine and observe recovery trends is a validated strategy, provided that one maintains a curious perspective toward the most detailed sleep metrics.
