How does stress affect your health?
When you are stressed, your body responds as though you are in danger. It makes hormones that speed up your heart, make you breathe faster, and give you a burst of energy. This is called the fight-or-flight stress response. 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. 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. Stress is linked to high blood pressure and heart disease.
Stress also harms your emotional health. It can make you moody, tense, or depressed. Your relationships may suffer, and you may not do well at work or school.
