How does stress affect health in teens?
Have you ever had butterflies in your stomach before taking a test? Or felt your heart speed up when a teacher asked you a question you couldn't answer? These are symptoms of stress. If the stress is over quickly, your body goes back to normal and no harm is done.
But if stress happens too often or lasts too long, it can have bad effects. You may have trouble sleeping, feel tired a lot, or have headaches or stomachaches. Long-term stress can make you more likely to get sick, and it can make symptoms of some diseases worse. If you tense up when you are stressed, you may develop neck, shoulder, or low back pain. And stress is linked to high blood pressure and heart disease.
Stress also can change how you behave. You might feel cranky and get upset at small problems or get angry and yell at others. Stress might make it hard to focus on your schoolwork. It may affect how well you perform in sports or other activities. Stress also can make you worry a lot or think that bad things are going to happen to you.
