    Internet gaming disorder (IGD) and insomnia are prevalent comorbid issues among college students, impacting their mental health.

  • 2

    Physical activity (PA) is negatively correlated with IGD and insomnia, suggesting it may serve as a protective factor.

  • 3

    The study utilized a three-wave longitudinal design with 475 Chinese college students to assess the relationships among PA, IGD, and insomnia.

  • 4

    IGD consistently correlates positively with insomnia, while insomnia does not significantly correlate with subsequent PA.

  • 5

    The findings indicate that PA can predict lower insomnia levels indirectly through reduced IGD, highlighting the importance of physical activity.
