Here are some science-backed ways to boost your memory: Firstly, sleep plays a key role. During sleep, your brain organizes memories. Aim for 8–10 hours nightly, especially before exams. Secondly, a balanced diet matters. Foods like fish (rich in omega-3), nuts, and blueberries support brain health. Avoid too much sugar, as it may cause memory loss. Thirdly, practice active learning. Instead of just reading, summarize information aloud or teach it to someone else. Additionally, physical exercise increases blood flow to the brain. Just 30 minutes of jogging daily can improve focus. Finally, reduce stress through deep breathing. High stress levels make it harder to recall information. 1. Why is sleep important for memory? A.
