    This study investigates the relationship between dimensions of fatigue and physiological variables in post-COVID-19 patients.

  • 2

    Thirty post-COVID-19 patients reported fatigue levels daily while physiological data were collected via wearable devices.

  • 3

    The interaction of multiple fatigue dimensions showed stronger associations with physiological changes than single dimensions.

  • 4

    Daily changes in fatigue correlated with fluctuations in resting heart rate and other physiological metrics, especially during sleep.

  • 5

    Findings suggest that understanding fatigue as a multidimensional construct may enhance monitoring and management in post-COVID-19 patients.
