Since final exams play a big part in your final grade, it is a good idea to be awake, alert and full of energy. As tempting as it may be to eat endless supplies of candy and drink can after can of Mountain Dew, this isn't a good idea. All the sugar is going to do is bring you up and then leave you crashing down. People who enjoy exercising should continue to do so during the stressful time of exams. It can take your mind off the books and give you a boost of energy, which is always a good thing.
Sleep is also a very important thing during stressful test taking times.
Dr. Viirre suggests at least six hours a night. This is hard for a lot of college students, especially those who want to pull those all-nighters that college students are known for. But it is actually better to get the extra sleep and go into the test rested. Other stress relief exercises that Dr. Viirre suggested are taking deep breaths and taking yourself away from the stressful situation. Not only does stress make you feel like you're going crazy, not only does it make you scream or cry at the drop of a hat, but it also makes people breath shallow.
