This point in the semester really begins a month long push for most students. Stress, your body's response to all the demands placed on it, is a natural and sometimes even helpful thing. There are two categories of techniques you can try to deal with your stress. Management techniques help you control aspects of your behavior and your environment. Setting good priorities, eliminating time wasters, improving study habits, scheduling tasks efficiently, and changing your environment to make it conducive to studying are all management techniques.
Deep breathing is by far the easiest relaxation technique to learn and practice.
Try to breathe deeply, letting your abdomen fill with air. Continue this cycle for a minute or two and you should feel more calm and relaxed. As you get more skilled at this technique, you will be able to increase the counts for each step. A number of other relaxation techniques including progressive muscle relaxation, guided imagery, meditation, and autogenics can be learned through tapes, books or classes, and, when practiced regularly, they are very effective. Relaxation doesn't just make you feel better at the time.
