Article: Pop a piece of gum in your mouth while you study to increase blood flow to your brain and increase arousal. Pick a mint flavor, like spearmint, peppermint, or wintermint for an extra invigorating bite. Keep a pack of gum in your backpack or pencil case so you always have it with you when you're studying. Snack on foods that are primarily composed of protein, like nuts, meat, or cheese, which fuel your body longer because they aren't as easily digested as carbs. For example, choose trail mix, beef jerky, or string cheese to eat while you work. Avoid sugary foods or drinks, like cookies or soda, along with carb-heavy foods, like potato chips. These might give you a quick boost, but you'll crash later on. Try to eat every 2 to 3 hours, even if it's just something small, to avoid low blood sugar, which makes you feel sleepy. Stay hydrated to avoid feeling drowsy or sluggish. Drink a full glass of water at least every 2 hours, which will help the blood flow in your brain and make you feel more alert. Keep a reusable water bottle with you that you can refill as you study. Avoid alcohol, particularly on days when you're studying or the day before. Drinking alcohol regularly can negatively affect your brain function along with dehydrating you. Drink a mug of coffee to wake yourself up quickly, as caffeine prevents the cells that make you feel tired from reaching your brain. Have the equivalent of 200 mg of caffeine, which is 12 oz (.35 L) of coffee or 24 oz (.7 L) of tea, for example, over the course of 24 hours. Be aware that coffee and other caffeinated drinks can actually be dehydrating, so you should drink water with them, too. Avoid drinking coffee or consuming anything with caffeine, like chocolate, soda, or tea, within 6 hours of when you plan to go to bed or you may have trouble falling asleep. Don't consume more than 200 mg of caffeine in a day. Too much caffeine can be very dangerous for your heart and can also worsen existing conditions, like anxiety or depression. While quick fixes are tempting, stay away from drinks, pills, or shots that promise instant energy or that are loaded with chemicals and too much caffeine. Be aware that they can have dangerous side effects, like increased anxiety or even heart problems. If you want to use energy drinks or products, talk to your doctor first. It can be very risky if you have certain health conditions, like high blood pressure or a weak heart.

What is a summary?
Chew mint gum to wake up your brain. Eat foods that are high in protein for longer-lasting energy. Drink at least 8 oz (.25 L) of water every 1 to 2 hours to fight fatigue. Consume a single caffeinated drink if you want an instant boost. Avoid energy drinks and pills that contain caffeine and/or chemicals.
