Stress is the reaction of the nervous system to a threat, or perceived threat. In the event of a physical attack, the nervous system recognises the danger and releases adrenaline into the bloodstream, to assist in either fighting off the attacker or running away. This is known as the "fight or flight" response. Once the threat subsides, the system returns to normal because the adrenaline has been used either fighting or running.
The everyday stresses that are now part of modern living are, of course, rarely life threatening, so it can be much more difficult for the body to release the adrenaline. If an appropriate outlet can't be found, the unused adrenaline stays in the nervous system and has a detrimental effect on the body. This can lead to serious health problems.
The key is to identify the source, and then relieve the stress with deep relaxation induced through hypnosis. The client can then be taught new, positive responses to the stress triggers, because it isn't the situations themselves that cause us stress, it's our reaction to them.
Disclaimer: as with any hypnotherapy practice, there is no guarantee that therapy will be effective in every individual case. Any therapy requires that the client be committed to change and be prepared to make the effort to make that change a reality. There is a possibility that you may not achieve your desired outcome.
