Stress is a necessary incident to being alive. Rather, you must learn to deal with stress in such a way that it does not trigger the silent response. We must have stress to survive. In these situations, we tend to internalize the overt, or visible, reaction to stress and add it to the invisible non-specific stress. Many illnesses have multiple causes.

The headache which occurs on the first day of a holiday, after the stress of packing for the family. See other Examples of stress-related illnesses in the table below. Tension headaches, on the other hand, usually start during the stress as a tension in the neck or the back of the head and gradually spread to the whole head. Some find that the tension is spreading to the whole body. Some tension headaches become so severe that they develop into a migraine.
