Hans Selye (1907-1982) was a Hungarian doctor who knew more about stress than anyone in the world. He was who first coined the word 'stress' in relation to health and who carried out most of the original studies into physiology of the stress reaction.
In the late 1930's Selye developed his theory of stress. He showed that living organisms have access to enormous reservoir of vital energy - what he called adaptation energy. On learning to draw on it and using it wisely the biological future of each individual life depends.
Selye feels differently about stress: 'it isn't how much stress you are subjected to but how you respond to it. This determines whether it causes you to break down or brings you joy.'
His book, Stress Without Distress, is a classic simple guide to stress and how to make it work for us and not against us. The book is a rich source of information about what stress is and what is not, how each of us have our optimum level of stress and how to live at it. It also tells why stress, when handled well becomes, as Selye says 'the spice of life.'
I highly recommend reading Selye's book for those who wishes to improve their response to stress.
