(1) We generally use the word “stress” when we feel that everything seems to have become too much. We are overloaded and wonder whether we really can cope with the demands placed upon us. Anything that poses a challenge or a threat to our well-being is a stress at all, many say our lives would be boring and would probably feel pointless. However, when the stresses affect both our mental and physical health they are bad. (2) The way we respond to a challenge may also be a type of stress. Part of our response to a challenge is physiological and affects our physical state. When faced with a challenge or a threat, our body activates resources to protect us; to either get away as fast as we can. Or fight. This is known as our ‘fight-or-flight’ response. (3) If you are upstairs at home and an earthquake starts, t he faster you can get yourself, and anyone else who might be at home, out the more likely you are all to survive. If you need to save somebody’s life during that earthquake by lifting a heavy weight that has fallen on them. You will need parts of your body to be activated to give you more strength. (4) To do this, our body produces larger quantities of the chemicals cortisol, adrenaline and noradrenaline, which trigger it to have a higher heart rate. Heightened muscle preparedness, sweating, and alertness. All these factors help us protect ourselves in a dangerous or challenging situation. (5) Non-essential body functions slow down, such as our digestive and immune systems when we are in a ‘fight-or-flight’ situation. All resources can then be concentrated or rapid breathing, blood flow, alertness and muscle use. (6) Most of us have varying interpretations of what stress is about and what matters, sort of us focus on what happens to us, such as breaking a bone or getting a promotion. While others think more about the event itself. In my opinion. What really matters are our thoughts about the situations in which we find ourselves.
