Abstract
On the one hand, social networks can predispose individuals to a sedentary lifestyle, as they have much less time for physical exercise. On the other hand, they can facilitate mental hyperactivity and divided attention. In this sense, if the amount of information is too high and significant, it may generate strong activation of the Default Mode Network (DMN). The objective of the study was to evaluate the modulating effect of social media on divided attention and sedentary lifestyle. This was a comparative, descriptive, and exploratory study. The sample consisted of 2,405 university students studying Physiotherapy, Primary Education, Nursing, or Sport Sciences. The following questionnaires were used: habits and use of social media among future education professionals, mental hyperactivity, and sedentary behavior in university students. The goodness-of-fit indices were: ?² = 7.83, df = 4; IFI = 0.98; CFI = 0.92; NFI = 0.91; RMSEA = 0.07. These values indicated a good fit of the theoretical model. Statistically significant differences (p < 0.05) were observed in the causal relationship between social media use and sedentary behavior (? = 0.42; p = 0.015), and between social media use and mental hyperactivity (? = 0.38; p = 0.023). Significant differences were also found in the relationship between sedentary behavior and mental hyperactivity under the modulating effect of the social media variable (? = 0.29; p = 0.042). Passive use of social media may pose a risk to the physical and mental health of users
