(B)
Many teenagers find it hard to concentrate. They sit down to do homework, but after five minutes they pick up their tablets. They start reading a book, yet their minds wander to social media or games. Some even forget what the teacher just said in class. This is a common problem, and science can help us understand why.
Research shows that teenagers’ brains are still developing. The part that controls attention does not fully mature until the mid-20s. At the same time, apps are designed to catch our attention with bright colours, exciting sounds and constant new messages. This makes it even harder for young brains to stay focused on one thing.
The good news is that you can train your brain to concentrate better. Here are some practical tips.
• Create a study space without distractions. Before you start working, put your phone in another room or turn it off. Clear games and snacks from your desk. This helps because your brain follows what your eyes see. When there are no temptations, your mind can stay on your work.
• Use the Pomodoro Technique. Study for 25 minutes, then take a 5-minute break. After four rounds, take a longer break of 15 to 30 minutes. This works because your brain can only focus well for a short time. Regular breaks help it stay fresh and active.
• Practise mindfulness for ten minutes each day. Sit quietly, close your eyes, and focus on your breathing. When your mind wanders, gently bring it back. Scientists found that this exercise strengthens the attention areas of the brain over time.
• Get enough sleep. Teenagers need 8 to 10 hours of sleep per night. When you are tired, your brain cannot work well. A well-rested mind learns faster and remembers more.
Improving focus takes time, but every small step helps. Start with one tip today, and you will soon notice a difference.
