Types of Stress
Mechanical Stress
The body is designed to withstand a certain amount of physical force – bumps, jerks and falls, but if the mechanical stress goes beyond the body's limit of adaptability, the effects may become stored as body stress. The causes may be sudden and violent, such as a car accident, a severe fall, or lifting a heavy object incorrectly.
Mental/Emotional Stress
These include fear of the future, financial worries, competition in the work-place, disintegrating family relationships. At times we experience sudden violent emotions, such as anger or shock, or we undergo milder but ongoing forms of mental strain, e.g. anxiety, depression and resentment.
Chemical Stress
Exposure to harmful chemicals may severely irritate the nervous system, causing the neck muscles to tighten.
The sources of chemical stress include pollutants in the air, insecticides and certain food additives and preservatives, colorants, artificial growth hormones.
