Feeling like there are too many pressures and demands on you? Losing sleep worrying about tests and schoolwork? Eating on the run because your schedule is just too busy? You're not alone. Everyone experiences stress at times — adults, teens, and even kids. But there are ways to minimize stress and manage the stress that's unavoidable.

What Is Stress?

Stress is a feeling that's created when we react to particular events. It's the body's way of rising to a challenge and preparing to meet a tough situation with focus, strength, stamina, and heightened alertness.

The events that provoke stress are called stressors, and they cover a whole range of situations — everything from outright physical danger to making a class presentation or taking a semester's worth of your toughest subject.

The human body responds to stressors by activating the nervous system and specific hormones. The hypothalamus signals the adrenal glands to produce more of the hormones adrenaline and cortisol and release them into the bloodstream. These hormones speed up heart rate, breathing rate, blood pressure, and metabolism. Blood vessels open wider to let more blood flow to large muscle groups, putting our muscles on alert. Pupils dilate to improve vision. The liver releases some of its stored glucose to increase the body's energy. And sweat is produced to cool the body. All of these physical changes prepare a person to react quickly and effectively to handle the pressure of the moment.

This natural reaction is known as the stress response. Working properly, the body's stress response enhances a person's ability to perform well under pressure. But the stress response can also cause problems when it overreacts or fails to turn off and reset itself properly.

Good Stress and Bad Stress

The stress response (also called the fight or flight response) is critical during emergency situations, such as when a driver has to slam on the brakes to avoid an accident. It can also be activated in a milder form at a time when the pressure's on but there's no actual danger — like stepping up to take the foul shot that could win the game, getting ready to go to a big dance, or sitting down for a final exam. A little of this stress can help keep you on your toes, ready to rise to a challenge. And the nervous system quickly returns to its normal state, standing by to respond again when needed.

But stress doesn't always happen in response to things that are immediate or that are over quickly. Ongoing or long-term events, like coping with a divorce or moving to a new neighborhood or school, can cause stress, too.

Long-term stressful situations can produce a lasting, low-level stress that's hard on people. The nervous system senses continued pressure and may remain slightly activated and continue to pump out extra stress hormones over an extended period. This can wear out the body's reserves, leave a person feeling depleted or overwhelmed, weaken the body's immune system, and cause other problems.

What Causes Stress Overload?

Although just enough stress can be a good thing, stress overload is a different story — too much stress isn't good for anyone. For example, feeling a little stress about a test that's coming up can motivate you to study hard. But stressing out too much over the test can make it hard to concentrate on the material you need to learn.

Pressures that are too intense or last too long, or troubles that are shouldered alone, can cause people to feel stress overload. Here are some of the things that can overwhelm the body's ability to cope if they continue for a long time:

Some stressful situations can be extreme and may require special attention and care. Posttraumatic stress disorder is a very strong stress reaction that can develop in people who have lived through an extremely traumatic event, such as a serious car accident, a natural disaster like an earthquake, or an assault like rape.

Some people have anxiety problems that can cause them to overreact to stress, making even small difficulties seem like crises. If a person frequently feels tense, upset, worried, or stressed, it may be a sign of anxiety. Anxiety problems usually need attention, and many people turn to professional counselors for help in overcoming them.

Signs of Stress Overload

People who are experiencing stress overload may notice some of the following signs:

Everyone experiences stress a little differently. Some people become angry and act out their stress or take it out on others. Some people internalize it and develop eating disorders or substance abuse problems. And some people who have a chronic illness may find that the symptoms of their illness flare up under an overload of stress.

Keep Stress Under Control

What can you do to deal with stress overload or, better yet, to avoid it in the first place? The most helpful method of dealing with stress is learning how to manage the stress that comes along with any new challenge, good or bad. Stress-management skills work best when they're used regularly, not just when the pressure's on. Knowing how to "de-stress" and doing it when things are relatively calm can help you get through challenging circumstances that may arise.

Here are some things that can help keep stress under control:

Build Your Resilience

Ever notice that certain people seem to adapt quickly to stressful circumstances and take things in stride? They're cool under pressure and able to handle problems as they come up. Researchers have identified the qualities that make some people seem naturally resilient even when faced with high levels of stress.

If you want to build your resilience, work on developing these attitudes and behaviors:

Learn to think of challenges as opportunities and stressors as temporary problems, not disasters. Practice solving problems and asking others for help and guidance rather than complaining and letting stress build. Make goals and keep track of your progress. Make time for relaxation. Be optimistic. Believe in yourself. Be sure to breathe. And let a little stress motivate you into positive action to reach your goals.
