As the end of the semester gets closer and closer, college students everywhere prepare for the weeks of freedom to come. Unfortunately, that freedom isn't given without a sacrifice: many late nights in the library completing a seemingly endless array of projects, term papers, and study guides. Here are five ways to power through those late nights:

1. Do jumping jacks in the stacks.

It may seem silly, but find a secluded place in the library to get some blood flowing. A few jumping jacks, push ups, or even jogging in place will be enough to help wake up your sleepy eyes.

2. Dress in comfy clothes.

One great thing about college libraries is that the only dress code in place is that you are, in fact, wearing clothes. Slap on that comfy t-shirt and those well-worn sweats for ultimate study-comfort. Hey! Even bring a throw blanket with you for when the AC gets turned up. Nothing infringes upon good work like being distracted by an uncomfortable outfit.

3. Coffee. Coffee. Coffee.

Yeah, this one seems like a no-brainer, but don't forget your much-needed best friend. Use your need for a refill as a nice excuse for a quick 10 minute study break.

4. Use a favorite snack as motivation or reward.

Set a study goal and tell yourself that when you reach it, you can have your favorite snack. This one needs a little self discipline, but it's a great way to get yourself to stay focused.

5. Breathe in the cool night air.

Take a moment to step out into the cool night air from the stuffy library. You'll be surprised how much it will perk you up and rejuvenate your tired body.
