Todd has "invented" or defined the word, "Hormesis". In science, you must sometimes either "invent" new words, or re-define "old words"....
Otis,
Thanks for the kind words.
Just to clarify: While I will take credit for devising the term "Hormetism", by no means am I the creator of "hormesis". The term "hormesis" was first coined in 1888 by the German pharmacologist Hugo Schulz, and has been the focus of scientific study for over a century:
http://gettingstronger.org/hormesis/Hormesis is a general scientific principle of biology, whereby a beneficial effect (improved health, stress tolerance, growth or longevity) results from exposure to low doses of an agent that is otherwise toxic or lethal when given at higher doses. It derives from biological defense and repair mechanisms that have evolved to protect organisms from environmental stresses. For more on the history of the hormesis concept, check out this overview:
http://en.wikipedia.org/wiki/HormesisTwo of the most prolific researchers in the field of hormesis are Edward Calabrese and S.I. Rattan. See Calabrese's excellent review article:
http://onlinelibrary.wiley.com/doi/10.1111/j.1539-6924.1999.tb00404.x/pdfHormetism is the practical application of hormesis in a deliberate and systematic way in order to increase strength and resilience. It is the application of a scientific principle to achieve human ends. I found that there was no word for this, so I had to invent a word. In this sense, it is also a philosophy or methodology, and it raises certain practical questions that go beyond science, for example:
- What is the optimal amount of "stressor" that you, as an individual, should apply to make the maximum gain in improving a given capacity, such as muscular fitness, visual acuity, immune strength, or emotional resilience?
- What is the optimal timing, frequency and rest period between training sessions?
- How do these protocols vary among individuals, and how can we determine what is optimal for each individual?
Hormetism is the practical philosophy advocated in this blog, which draws from (but is not fully determined by) the objective science of hormesis. Hope that helps to explain the difference between these terms.
