Everyone has those days where they sleep a little too little, or are just plain tired. To stay awake, some people try the strangest things, like hypnosis, or hurting themselves. However, there are many simpler solutions. Maybe these will help!

    1. Drink ice cold water

    Emphasis on the "ice cold." Warm water will only make your body temperature go up, making you more tired. By drinking ice water, or at least chilled water from a source, or a water fountain, you will lower your body temperature, and get an icy feel in your mouth. This will definately help you stay awake, and some people swear that it's even more powerful than energy drinks or coffee. Just remember that carrying around a water bottle with ice in it is more convenient than getting up and walking to the water fountain every five minutes.

    2. Stay cold

    The colder you are, the more of a chance you have of staying awake. When you fall asleep, your body temperature increases, making you sleepy. If you're wearing a coat or sweatshirt, no matter how cozy you feel, take it off. Do everything in your power to make yourself cold. Open the windows, or turn on the AC. Anything helps.

    3. Take notes in the margin

    No, not those kinds of notes. I mean, record the time, and then how you feel beside it. Do this every minute, it will help you feel more awake. For example, you could write- "9:34 AM, still feeling very sleepy, runny nose, hungry." Trust me, even though your teachers will stare at you after you hand in assignments, it will help to keep you wide awake.

    4. Make yourself uncomfortable

    There's a fine line between uncomfortable and pain, however. You need to not inflict pain, but don't relax at the same time. Request a harder chair, or sit in a way foreign to you. You might also want to skip lunch, because beside the fact that after eating, your body gets sleepy, you will also be hungry, and that often keeps people awake.

    5. Drink energy drinks

    Now, there's one simple rule to energy drinks- don't stop at one. If you just buy one and drink it, you will crash. Everyone does, you'll just feel sleepier than before after an hour or two of awakeness. Go out and buy one or two energy drinks. Drink half of one every hour or so, and it will last the entire day. You won't feel hyper, but you'll feel awake since you're not drinking the entire drink at once. My recommendations for energy drinks that work the best are Monster Java, (Not plain Monster, those don't do too much) Cocaine Energy, (watch out for the burn in your throat with that one) and No Fear energy. You do not want Red Bull, it claims it helps you stay awake, but in my experience, and in all of my friends, it did nothing whatsoever.

    Well, those are my five tips to keeping you awake. On a side note, You could also try taking a power nap. This means just taking a ten to twenty minute nap, no more, no less. Any more will result in you having rapid eye movements, (REM) and you will feel even more tired after getting up. Any less, and it won't do anything to your body. Good luck!

    每个人都会有睡得很少的日子，或者无缘无故很累的时候，为了保持提神，人们出尽法宝，动用催眠大法，甚至自残。其实，要想保持头脑清醒，我们可以尝试更简单的方法，说不准还真有帮助。

    1.喝冰水

    强调“冰冷”，温水会使你的体温升高，使你更累。喝些冰水，或哪个地方来的冷水，又或者水龙头里的水都可以降低体温，使嘴巴产生一种冰凉的口感, 这样做一定可以帮助你保持头脑清醒，有些人打包票说喝冰水比喝能量饮料，咖啡更能提神。谨记随身携带一瓶加冰的水永远比每隔5分钟就要站起来跑到水龙头里喝水要方便得多。

    2. 时刻保持冷感

    你越是觉得冷，头脑就越是清醒。当你开始打瞌睡的时候，体温就会上升，体温一升高，整个人就会觉得要昏昏睡去似的。这时，如果你还穿着一件大衣或毛衣的话，不管你觉得有多惬意，多暖和，把它脱下来。尽你所能令自已寒冷，打开窗户，或者开空调，做任何有所帮助的事情。暖意的不鑵高。头脑就越是清醒。如果你觉得昏昏欲睡，那

    3. 在作业空白处作记录

    不，不是那些笔记。我的意思是，记录时间，再记录你的感受。每五分钟做一次，这有助你感觉更加清醒。例如，你可以写上午9：34分，仍然觉得很困，流鼻涕，肚子饿。相信我，尽管你在交完作业之后你的老师也许会冲你吹鼻子瞪眼睛，但这样做会让你保持大清醒。

    4. 让你自已感觉不舒适

    不舒服与伤痛之间是有明显区别的。然而，你无需忍受疼痛，但同时也不能放松。找一张硬一点的椅子来坐，或者保持一种别样的坐姿。你可能也会想不吃饭。因为吃了饭之后，人就会犯困。空着肚子挨饿，人就会一直保持清醒的脑袋。

    5. 喝功能饮料。

    现在，喝功能饮料有一个简单的规则-不要只喝一瓶。如果你只买一瓶并把它喝光。你会想找个地方一睡方休的。

    每个人都不例外。喝完饮料后只有一个或两个小时是清醒的，之后则更困。走出去买一或两瓶功能饮料，每隔一小时喝半瓶，就可以持续一整天不犯困。

    你不会有亢奋的感觉，但是，你会觉得很清醒，因为你没有一次性喝完整瓶饮料。我认为最好使的功能饮料是Java 怪兽，可卡因能量（瞧瞧你喝了之后，喉咙里哪种火辣辣的劲）无惧能量。你不要喝红牛，虽然红牛口口声声说它可以帮助你提神，但是依我的经验和我所认识的朋友的经验，它丝毫作用也没有。

    嗯， 这就是我的提神5招。你也可以小息充电，打个盹。意思是说小息10到20分钟，时间不能长也不能短。长了，会使你的眼睛转得更快，令你在睡醒之后感觉更累。短了，对你的身体不起任何作用。祝你好运。
