Have you had a headache during a test? Have you ever been so worried about something that you have a headache or even can't sleep at night? If so, then you know what stress is. This worry in your mind can make your body feel bad. You may feel angry, sad, scared, or afraid — all of which can give you a stomachache or a headache.

    However, there are different kinds of stress. Good stress might happen when you are called to answer questions in class or when you have to give a speech. For example, you may do a better job on your test if the stress pushes you to prepare better before the test.

    On the other hand, bad stress can happen if the stress lasts too long. You may not feel well if your parents are fighting, if a family member is sick, if you are having problems at school, or if anything else makes you unhappy every day. That kind of stress isn't going to help you. And it can actually make you sick.

The best way to fight the stress is to have a balanced life.  If you get enough sleep and eat properly, and if you exercise and leave time for fun, you'll probably feel less stressed.
