KENT State University has found that university students who spent large amounts of time on their phone – as much as a truly obsessed 14 hours per day – were less fit than those who spent around 90 minutes a day.
While the concept of mobile devices allows “on the go” communication, the more students used their devices, the more sedentary they were, the report said. Plus those who spent more time on their mobile devices were more likely to engage in other sedentary forms of entertainment, such as playing video games or watching films.
