Stress is a term that is frequently used in everyday conversation. The conventional meaning of the word stress – too much to do, too much to worry about – was not part of the vocabulary some fifty years ago. In the 1930s the Hungarian scientist Hans Selye, the godfather of stress research, took an engineering concept and applied it to humans 1. Stress in general refers to force exerted on a system. In human terms however it would more correctly refer to circumstances that either threaten or are perceived to be threatening to a person’s wellbeing and consequently be taxing on their ability to cope with these circumstances 2.
There is also stress which is not as particularized or subjective, such as ambient stress. This stress encompasses situations like constant environmental conditions which are difficult, if not impossible, to control by the individual, i.e. excessive noise, traffic, pollution and crowding2. According to Ewart and Suchday’s, researchers 6 who developed a scale called City Stress Inventory (CSI), urban poverty and violence can also be considered as sources of environmental stress 2.
An important point to make is that the perception of a threat can be as stressing as an actual threat and the body and brain can react in exactly the same way as a result. Body and mind relationship have been studied by medical researchers for a long time now. The so-called placebo effect is a good example of this phenomenon where in clinical experiments, people who are given inert substances made to look like medicines, such as a sugar pill, often experience the same health improvement as those patients who are given real medication. Researchers have also noted that some conditions and illnesses have no physical explanations. Doctors classify these conditions as psychosomatic, as they seem to be caused by the psyche 8.
