In a perfect world, nobody would be staying up all night to study. In the real world, all-nighters happen, even to the best of students. If there's a golden rule to combining cramming with sleep deprivation, it's this: Know Thyself.
Everybody's body is unique. Whether big, small, short, tall, older, younger, lighter, darker, we all need certain amounts of fuel to keep us chugging along. Fuel comes from food; fuel comes from sleep. All living things — plants, animals, fungi included — are subject to a circadian rhythm, a 24-hour cycle of cell regeneration, brain wave activity, hormone production, and other critical activities.
When circadian rhythm is thrown off for some reason (like an all-night round of study), the human body responds in different ways. Consider jet leg. Some people experience slight fatigue or discomfort when switching time zones during long-distant traveling; others lose their appetites, get sick at the stomach, become irritable or even irrational.
The aftermath of your all-nighter will vary with your personal makeup. For example, if you rely on coffee to keep you awake, how much is just enough and how much will produce nervousness, muscle twitching, rambling thoughts, or a racing heart? Stimulants that perk you up can also make you sick.
And what about lighting? Some students prefer bright-as-day lights; others swear by dim surroundings to stay more alert. Knowing how to adjust your environment will help you achieve your purpose — without crimson eyes or a pounding head.
Here are a few more ideas to entertain if you think you might be spending some sleepless nights with your studies. These hints come from college students who've been there and done that — more than once:
Avoid pasta or other carb-heavy snacks; they may make you sleepier. Go for fruit or protein. Forget fatty foods. Don't get too hungry or too full. Stock up on crunchy stuff to munch on. Eat ice. Chew gum.
Take breaks throughout the night. Get away from the same kind of work. If you've been gazing at a computer screen, don't go browsing Web sites. Clear your mind with meditation. Do a couple of pushups. Juggle. Open the windows and let air circulate around you. Go outside and walk around.
Pull your all-nighter in the library or in a computer science lab. Have a friend with you for motivation (shared misery?). If you wind up too tired to continue, you still have the walk home to get you refreshed and revived.
Invest in a blue-tinted light bulb. Some seasoned overnighters say that dim blue light's the only way to go for concentration.
Cat nap, if you that's what your body is begging for. Getting a few hours of sleep can put you in a more productive frame than busting through with no shut-eye.
Don't get dehydrated. Drink a full glass of water when you think you might doze off.
Splash your face with cold water. Turn a fan on your face. Some students recommend a warm water facial refresher, believing that blood circulates better to their brains with the applied heat.
Lubricate your tired eyes with non-medicinal eye drops, paying attention to directions on the bottle. (Don't overdose!) Soothing eye wash or saline solution might also get the grit out of scratchy eyes.
Do yourself a favor by pledging never to pull another all-nighter — and stick to it. If you sense that you may be headed down a path of regular sleep deprivation, rethink your classload. Develop better organization skills. Give your body a break.
