Minute quantities of a harmful agent bring about changes so small that only the initial reactions that would be evoked by a large dose are involved. Control mechanisms appear to subjugate normal processes to place the organism in a state of alert and repair. In the absence of harmful doses of the hormetin, the stimulated condition of the organism allows a reallocation of resources to basic physiologic functions, such as growth, development, or defense, which had previously been more repressed. The alerted organism utilizes nutrients more efficiently, grows faster, shows improved defense reactions, matures faster, reproduces more effectively, has less disease, and lives longer. In the context of the nonspecific resistance phase of the general adaptation syndrome following stress, the changed state of the organism allows it to do many things better than it would do otherwise.
