stress_brain.JPGYou are about to take a test. The coach is announcing who made the team. Your best friend is mad at you. Most people find such situations stressful. Stress can be defined as an emotional or physical demand or strain (a "stressor") that causes your body to release powerful neurochemicals and hormones. These changes help your body gear up to respond to the stressor. Your blood-sugar levels and blood pressure rise; your heart beats faster; your muscles tense.

There are different levels of stress: Short-term stress can cause uncomfortable physical reactions, but can also help you to focus. Long-term stress—such as stress caused by illness, divorce, or the death of a loved one—can lead to serious health problems. Traumatic events—such as natural disasters, violence, and terrorism—can cause post-traumatic stress disorder (PTSD), a serious illness.

Brain research now indicates that people exposed to stress are more likely to abuse alcohol or other drugs, or to relapse to drug addiction.

Read on to get important facts about this connection.

How Your Body Responds to Stress

Your body's central nervous, endocrine, immune, and cardiovascular systems are involved in responding to stress. 

The physical responses can vary: Short-term responses can cause a racing heart, sweaty palms, and a pounding head. Long-term responses can cause back pain, high blood pressure, sleeplessness, and an inability to make decisions. Constant stress floods the body with stress hormones, which can increase the risk of serious health problems.

The hormone that initiates the body's response to stress, CRF, is found throughout the brain. Drugs of abuse also stimulate release of CRF. See the diagram above for how this works. 

 

Myth vs. Reality

Myth 1: Drug abuse is harmful, but it does relieve stress. 
Reality: Some drugs of abuse affect your brain the same way stress does. Long-term abuse of drugs makes users more sensitive to everyday stress than non-users. 

Myth 2: All stress is bad for you. 
Reality: Stress can help you deal with tough situations. It can also be associated with positive changes, such as a new job. However, long-term stress can lead to physical and emotional health problems. 

Myth 3: Everyone deals with stress in the same way. 
Reality: People deal with stress in different ways. How you deal with stress determines how it affects your body.

Managing Stress
Anyone can learn to manage stress, but it does take practice. Here are some practical tips:

  • Take care of yourself. 
    Healthy foods, exercise, and enough sleep really do make you feel better and better able to cope!

    Step away from an argument or confrontation by taking a deep breath. Go for a walk or do some other physical activity.

    If you don't achieve something you were trying for, practice and prepare for the next time. Or check out some other activity
  • Talk about it.
    Talking to an understanding listener who remains calm can be very helpful.

"We all must develop healthy ways to manage stress, and avoid turning to drugs or other substances to escape stressful realities."

—Nora D. Volkow, M.D., Director, National Institute on Drug Abuse
