Final answer:
The tertiary consequences of allostatic load can be both psychological and physiological. Prolonged or repeated exposure to stress can contribute to the development of psychological disorders and physiological conditions such as heart disease. These consequences are often the result of sustained physiological reactions to stress.
Step-by-step explanation:
The tertiary consequences of allostatic load can be both psychological and physiological. In terms of psychological consequences, prolonged or repeated exposure to stress can contribute to the development of psychological disorders such as post-traumatic stress disorder and major depressive disorder. Physiological consequences of allostatic load include an increase in susceptibility to heart disease and impaired function of the immune system. These consequences are often the result of sustained physiological reactions to stress, which can lead to wear and tear on the body and weakened immune system functioning.
