"Hans Selye found that the adrenals are a major component of our adaptive system. In the first phase of stress, there is a shock reaction (with changes resembling those of estrogen dominance), with injury to various tissues. In the second phase, the adrenals protect the animal, and this protection continues until something is exhausted. By exposing rats to a preliminary stress, Selye found that he could induce adaptation to other, later stresses — a kind of immunization to stress."

what’s even cooler is that i can see what stage of stress an individual is in based on their HTMA test results.
