Do you ever feel a stomachache during a test? Are you ever so worried about something that you even have a headache or can’t sleep at night? If so, then you know what stress is. Stress is what you feel when you are worried about something. You may feel angry, sad, scared, or afraid —all this can give you a stomachache or a headache.

There are different kinds of stress. Some kinds of stress are good and others are bad. Good stress may happen when someone asks you to answer questions in class or when you have to give a report. This kind of stress can help you to finish things better.

However, bad stress can happen if the stress lasts too long. You may not feel well if a family member is sick, if you’re having problems at school, or if anything else makes you upset every day. That kind of stress isn’t going to help you.

The best way to keep stress away is to have a balanced life. If you get enough sleep and food, and if you exercise and leave time for fun, you’ll feel less stress.
