Hans Selye and the GAS: Generalized Adaptation Syndrome

Hans Selye was a
Hungarian endocrinologist
who worked in Canada for
most of his life.
He conducted pioneering
experiments on stress during
the 1950s and ’60s.
He discovered the General
Adaptation Syndrome by
accident, while injecting
mice for hormone research.
He invented the term
“stress” during the 1930s.
Turns out both good and bad
stressors result in the GAS.
