Summarize the following:
Studies have shown that teenagers’ bodies don’t function well early in the morning, so many middle and high schoolers have trouble focusing in school because they’re sleepy. A large part of why many students don’t like school is that they’re tired. Teenagers’ bodies naturally want to stay up late and sleep in late, but you need to train your body to your school schedule.  Make yourself get in bed at a reasonable hour, even if you’re not tired yet. Don’t watch TV or use your computer for at least an hour before you go to bed.  Don’t take naps during the day, so you’ll be more tired at night. It might not be immediately obvious how your diet relates to your performance in school, but it’s very important! A poorly balanced diet might fill you up, but it won’t necessarily give you the energy you need to stay focused and productive, and you won’t be motivated if you’re tired. Remember to always eat breakfast to help power up your body first thing in the morning.  Fish with omega-3 and whole grains improve memory function. Dark fruits and vegetables provide antioxidants that improve memory and cognition.  Foods rich in Vitamin B, including spinach, broccoli, and beans, are good for memory and alertness. Many studies have demonstrated a link between exercise and improved productivity, so stay active. Regular exercise will not only help you focus when you’re studying, but it also improves your mood. Being focused and in a good mood are very important to staying motivated for school.
Get 8-10 hours of sleep every night. Eat a healthy diet. Get enough exercise.
