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!

    每個(gè)人都會(huì)有睡得很少的日子，或者無緣無故很累的時(shí)候，為了保持提神，人們出盡法寶，動(dòng)用催眠大法，甚至自殘。其實(shí)，要想保持頭腦清醒，我們可以嘗試更簡單的方法，說不準(zhǔn)還真有幫助。

    1.喝冰水

    強(qiáng)調(diào)“冰冷”，溫水會(huì)使你的體溫升高，使你更累。喝些冰水，或哪個(gè)地方來的冷水，又或者水龍頭里的水都可以降低體溫，使嘴巴產(chǎn)生一種冰涼的口感, 這樣做一定可以幫助你保持頭腦清醒，有些人打包票說喝冰水比喝能量飲料，咖啡更能提神。謹(jǐn)記隨身攜帶一瓶加冰的水永遠(yuǎn)比每隔5分鐘就要站起來跑到水龍頭里喝水要方便得多。

    2. 時(shí)刻保持冷感

    你越是覺得冷，頭腦就越是清醒。當(dāng)你開始打瞌睡的時(shí)候，體溫就會(huì)上升，體溫一升高，整個(gè)人就會(huì)覺得要昏昏睡去似的。這時(shí)，如果你還穿著一件大衣或毛衣的話，不管你覺得有多愜意，多暖和，把它脫下來。盡你所能令自已寒冷，打開窗戶，或者開空調(diào)，做任何有所幫助的事情。暖意的不鑵高。頭腦就越是清醒。如果你覺得昏昏欲睡，那

    3. 在作業(yè)空白處作記錄

    不，不是那些筆記。我的意思是，記錄時(shí)間，再記錄你的感受。每五分鐘做一次，這有助你感覺更加清醒。例如，你可以寫上午9：34分，仍然覺得很困，流鼻涕，肚子餓。相信我，盡管你在交完作業(yè)之后你的老師也許會(huì)沖你吹鼻子瞪眼睛，但這樣做會(huì)讓你保持大清醒。

    4. 讓你自已感覺不舒適

    不舒服與傷痛之間是有明顯區(qū)別的。然而，你無需忍受疼痛，但同時(shí)也不能放松。找一張硬一點(diǎn)的椅子來坐，或者保持一種別樣的坐姿。你可能也會(huì)想不吃飯。因?yàn)槌粤孙堉�后，人就�?huì)犯困�？罩�肚子挨餓，人就會(huì)一直保持清醒的腦袋。

    5. 喝功能飲料。

    現(xiàn)在，喝功能飲料有一個(gè)簡單的規(guī)則-不要只喝一瓶。如果你只買一瓶并把它喝光。你會(huì)想找個(gè)地方一睡方休的。

    每個(gè)人都不例外。喝完飲料后只有一個(gè)或兩個(gè)小時(shí)是清醒的，之后則更困。走出去買一或兩瓶功能飲料，每隔一小時(shí)喝半瓶，就可以持續(xù)一整天不犯困。

    你不會(huì)有亢奮的感覺，但是，你會(huì)覺得很清醒，因?yàn)槟銢]有一次性喝完整瓶飲料。我認(rèn)為最好使的功能飲料是Java 怪獸，可卡因能量（瞧瞧你喝了之后，喉嚨里哪種火辣辣的勁）無懼能量。你不要喝紅牛，雖然紅�？诳诼暵曊f它可以幫助你提神，但是依我的經(jīng)驗(yàn)和我所認(rèn)識(shí)的朋友的經(jīng)驗(yàn)，它絲毫作用也沒有。

    嗯， 這就是我的提神5招。你也可以小息充電，打個(gè)盹。意思是說小息10到20分鐘，時(shí)間不能長也不能短。長了，會(huì)使你的眼睛轉(zhuǎn)得更快，令你在睡醒之后感覺更累。短了，對(duì)你的身體不起任何作用。祝你好運(yùn)。
