For most of us, four weeks into the new semester signals a time for exams, papers, and deadlines we've been desperately trying not to think about. Spending hours at a time in the library, textbook open and cold brew coffee in hand, may seem daunting unbearable, to say the least. But does it have to be this way?

Studies show that taking mental breaks can actually help us stay focused, and improve performance during stressful, time-consuming tasks. Energy is limited; when we push ourselves too hard for too long, we break. So if your mind was fried after binge-watching Season 1 of Stranger Things, just imagine how it'd feel after reviewing PowerPoint slides for eight or nine hours straight... Instead, setting aside short intervals during long periods of work to rest and recharge allows us to feel better and be more productive in the long-term.

When your study willpower begins to fade, coffee high turns to throbbing headache, and you find yourself rereading the same paragraph over. and. over. again, here's how to treat yo'self with some beautifully ~free~ time:

1. Turn up the volume.

Maybe it's Mozart's Serenade in G that helps you focus best or Strawberry Fields Forever to get you into the creative writer's mindset. Maybe you need to put on ANTI by Rihanna and dance around the room (alone, or with a friend) to remind yourself that you've got this. Whatever your music preference, keep the good vibes flowin'.

2. Sweat it out.

Exercising is an easy way to distract our cluttered minds, by releasing endorphins that activate the "feel good" receptors in our brains. So plan your day around a Zumba or Spinning class. Climb a few flights of stairs. When you don't have time to sneak a run in, a quick walk around campus does the trick, too. And if you're in the library, chances are you're already sporting your comfiest pair of Lulu Lemon leggings. Put 'em to good use.

3. Just breathe.

There are great (free!) phone apps, like Calm, Headspace, and MINDBODY that provide relaxation techniques, guided meditations, and access to local yoga classes. Practicing mindful awareness is a great way to refocus and approach problems from a fresh, clearer perspective.

Don't make your semester any harder than it has to be. Go ahead and take a break (or two).
