Stress is a normal part of life that can help us learn and grow. Conversely, stress can cause people significant problems.

Stress releases powerful neurochemicals and hormones that prepare people for action (to fight or flee). If they don't take action, the stress response can lead to health problems. Prolonged, uninterrupted, unexpected, and unmanageable stresses are the most damaging types of stress.

Many of the ways in dealing with stress; such as, with drugs, pain medicines, alcohol, smoking, and eating, actually are counterproductive in that they can worsen the stress and can make us more reactive (sensitive) to further stress.

Stress can be best managed by regular exercise, meditation, or other relaxation techniques; structured time outs, and learning new coping strategies to create predictability in the lives of people.

The management of stresses depend mainly on the willingness of a person to make the changes necessary for a healthy lifestyle.
