The Health and Safety Executive define stress as "...the adverse reaction people have to excessive pressures or other types of demands placed upon them.”
Stress is one of the commonest complaints of the 21st century. Pressure is the cause of many daily stresses and everyone reacts differently to it – indeed what is unbearable pressure to one can be stimulating and exciting for another! The key is to identify what your pressure threshold is.
A little bit of stress can in fact be good for you! It gets the adrenaline pumping, which can improve your performance, whether at work, school or on the sports field. The human body is designed to cope with a certain level of stress. This is believed to derive from primitive times when adrenaline helped cave men cope with perceived danger by fighting or retreating - commonly known as the "fight or flight" reaction.
