We define stress as the state of dynamic tension created when you respond to perceived demands and/or pressures from outside and from within yourself. These demands and pressures build up till they trigger the stress response and the release of adrenaline and cortisol. In our graphic above, the person looks at external demands and pressures, indicating the role played by perception. How you interpret a situation determines how it affects you. When Demands and Pressures get out of hand, the stress response becomes either too intense, occurs too frequently, or continues for too long. Stress makes itself felt through a range of Physical and Mental Symptoms that make things even worse by becoming sources of demand and pressure in and of themselves.
