Discuss the arguments put forth by the hormonal stress theory of aging.
What will be an ideal response?
The hormonal stress theory states that aging in the body's hormonal system can lower resistance to stress and increase the likelihood of contracting a disease. When faced with external challenges such as stressful situations, the human body adapts by altering internal physiological processes. This process of adaptation and adjustment is referred to as allostasis. Allostasis is adaptive in the short term; however, continuous accommodation of physiological systems in response to stressors may result in allostatic load, a wearing down of body systems due to constant activity. Normally, when people experience stressors, the body responds by releasing certain hormones. As people age, the hormones stimulated by stress remain at elevated levels longer than when people were younger. These prolonged, elevated levels of stress-related hormones are associated with increased risks for many diseases, including cardiovascular disease, cancer, diabetes, and hypertension.
