*Topic Stress* *Causes:* The cause of stress is produced when the events of life, whether physical or psychological, are greater than the ability to cope. *Psychological stress* may be for positive reasons ( a new job) or negative ( the loss of a job). In all stress cases the repercussions on the body are very similar. The effects of stress can affect all of the organs and functions of the body, its effects tend to be concentrated on: * The heart and the cardiovascular system, which is obliged to work harder. * The immune system, which is weakened in favor of other bodily functions. This reduces resistance to infections, and probably to cancer as well, and other diseases. Certain foods can help the body adapt to stress, while others weaken it.
