A large research project followed children from about age 10 for several years. Scientists recorded how often adolescents used social media each day and measured reading, vocabulary and attention over four years. They found that more daily social media use was linked with slower progress in reading and learning new words. This slower growth could make some schoolwork harder for children.
The study also found that frequent social media users had more trouble keeping their attention. However, these users were faster on some reaction-time tests. To reduce possible harms, researchers suggest limiting screen time, avoiding phones before bed, and waiting longer before giving children a smartphone.
