Stress is an adaptive response.
It is the body's reaction to an event that is seen as emotionally disturbing, disquieting, or threatening. Major causes of stress include illness, job changes, moving, separations and divorces, deaths in the family, and financial difficulties. Stress from tension and anxiety can take a major toll on the body. Don't fret though, there are many ways to prevent or relieve stress. There are relaxation techniques that can be used such as meditation, breathing exercises, yoga, creative visualization, progresssive muscle relaxation, stretching, and biofeedback.
