Summary

What is stress?

Stress is how your brain and body respond to a challenge or demand. When you are stressed, your body releases certain hormones. Hormones are chemicals that travel in your bloodstream and control how different parts of your body work. The hormones that are released when you are stressed make you alert and ready to act. They can raise your blood pressure, heart rate, and blood glucose (blood sugar) levels. This response is sometimes called a "fight or flight" response.

Everyone gets stressed from time to time. There are different types of stress. It can be short-term or long-term. It can be caused by something that happens once or something that keeps happening.

Not all stress is bad. In fact, it can help you survive in a dangerous situation. For example, one kind of stress is the jolt you may feel when a car pulls out in front of you while you are driving. This jolt of hormones helps you quickly hit the brakes to avoid an accident. A little short-term stress can sometimes be helpful. For example, the stress of having a deadline for school or your job may push you to get your work done on time. Once you finish it, that stress goes away.

But stress that lasts a long time can harm your health.

What causes long-term stress?
