Good morning, everyone. Today we're going to discuss the impact of social media on academic performance. A recent study at a UK university followed 500 students over two semesters. The results showed that students who limited their social media use to 30 minutes per day scored, on average, 12% higher in their final exams compared to those who used it without restrictions. Interestingly, the study also found that the time of day mattered: evening usage had a more negative effect than morning usage, likely due to disrupted sleep patterns. However, the researchers noted that completely banning social media was not beneficial, as it reduced students' sense of community. So, the key is moderation, not elimination.
