In a study published in Pediatrics, it was revealed that a moderate amount of screen time resulted in an improved rate of recovery for children with concussion symptoms. In the study conducted at the University of Calgary, the researchers analyzed the data of more than 700 children with concussions. They also looked at the impact of the screen time self-reported by the children in the first 7–10 days following an injury and symptoms reported by them and their caregivers over the following six months.

The study was conducted as a part of a larger concussion project called Advancing Concussion Assessment in Pediatrics (A-CAP) led by psychology professor Dr. Keith Yeates at the University of Calgary. He explained that kids use smartphones and computers to stay connected with peers, so complete removal of those screens could lead to feelings of disconnection, loneliness, and lack of social support. Therefore, the complete removal of screen time is likely to negatively impact kids mental health, thereby increasing the recovery time of the patient.

On the other hand, the findings of the study revealed that the amount of time spent in front of screens during the early recovery period made little difference to long-term health outcomes. The researchers also observed that screen time seemed to have less bearing on symptoms than other factors such as the patient′s sex, age, sleep habits, physical activity, or pre-existing symptoms. Dr. Yeates concluded that encouraging concussion patients to sleep well and gradually engage in light physical activity will likely do a lot more for their recovery than keeping them off their smartphones.
