Being healthy overall will help you be more alert and learn things more easily! Here are some specifics, though:
- Get some sleep! Kids and teenagers need 10-12 hours of sleep every night to be healthiest and most alert. Most modern kids don't get this much, which is why you see so many of them falling asleep at school and doing poorly in their grades.
- Eat right! You have already heard all this so many times that I know you understand the difference between healthy food and unhealthy! Cut out the junk food, fatty and greasy stuff, and "energy drinks" or sugary sodas - all these things make you feel even more tired and sluggish after a few minutes! Eat more fruit and veggies, and drink 8-10 glasses of water every day to flush the toxins out of your body.
- Move it! You need at least 30 minutes of good exercise - if you're not sweating and breathing hard, you're not doing it right! - at least 3-4 times a week, and preferably every day or two. If you're not healthy, your brain is not healthy.
- Avoid drugs and alcohol! I shouldn't even have to write this one down! When you take drugs and drink to excess (that means more than just one drink every few days), your body wants more - your brain is too busy thinking of how to get more drugs to be able to think about passing school.
