What did Hans Selye discover?
In 1936 Selye wrote about a stress condition known as general adaptation syndrome (GAS). He first observed the symptoms of GAS after injecting ovarian extracts into laboratory rats, an experiment he performed with the intent of discovering a new hormone.
Why is Hans Selye referred to as the father of stress?
Hans Selye is often referred to as the “father of stress research”. He developed an understanding of the evolutionary purpose of stress as involving the “fight or flight syndrome”. A critical part of his theory of stress is termed the General Adaptation Syndrome.
