Stress hormones are secreted by endocrine glands to modify one's internal environment during the times of stress. [1] By performing various functions such as mobilizing energy sources, increasing heart rate, and downregulating metabolic processes which are not immediately necessary, stress hormones promote the survival of the organism .

Endocrinology (from endocrine + -ology) is a branch of biology and medicine dealing with the endocrine system, its diseases, and its specific secretions known as hormones.It is also concerned with the integration of developmental events proliferation, growth, and differentiation, and the psychological or behavioral activities of metabolism, growth and development, tissue function, sleep ...
Endocrine component: Heterocrine glands produce hormones, which are chemical messengers that travel through the bloodstream to target organs or tissues. These hormones play a vital role in regulating numerous physiological processes, such as metabolism, growth, and the immune response.
Allostatic load is the accumulation of stressors and maladaptive responses that may result in an extreme state, where the stress response does not terminate. [ 26 ] The long-term impact of childhood adversity (e.g., abuse, neglect) has been shown to have lasting effects, including the increased risk for allostatic load in adulthood. [ 27 ]
CRH and ACTH are tropic hormones because they act on the anterior pituitary gland and adrenal glands, respectively, both of which are endocrine glands. [1] Non-tropic hormones are thus often the last piece of a larger process and chain of hormone secretion. Both tropic and non-tropic hormones are necessary for proper endocrine function.
The nervous and endocrine systems often act together in a process called neuroendocrine integration, to regulate the physiological processes of the human body. Neuroendocrinology arose from the recognition that the brain, especially the hypothalamus , controls secretion of pituitary gland hormones, and has subsequently expanded to investigate ...
The stress induced during exercise results in an increase in the hormones, epinephrine and norepinephrine, which are known for the body's "fight or flight" response. Increased secretion of catecholamines are a hormone response regulated by the sympathoadrenal system (SAS) and the hypothalamic-pituitary-adrenal axis (HPAA). [10]
Endorphins are released from the pituitary gland, typically in response to pain, and can act in both the central nervous system (CNS) and the peripheral nervous system (PNS). In the PNS, β-endorphin is the primary endorphin released from the pituitary gland .
