Psychology’s Influence on Immunity and Disease
The body’s response to stress is a finely tuned physiological process designed to prepare
the organism for a fight-or-flight situation. This reaction is primarily orchestrated by two
interconnected systems: the sympathetic nervous system (SNS) and the hypothalamic-pituitaryadrenal (HPA) axis (Chu et al., 2024). When confronted with a perceived threat, the SNS is
activated, triggering a rapid release of adrenaline and noradrenaline. These hormones increase
heart rate, blood pressure, respiration, and muscle tension, providing the body with the necessary
energy and resources to confront the stressor. Simultaneously, the HPA axis is initiated, leading
to the secretion of cortisol. Cortisol acts as a longer-term stress hormone, influencing
metabolism, immune function, and blood sugar levels. While this acute stress response is
essential for survival, chronic activation can lead to detrimental effects on various bodily
systems, including the cardiovascular, digestive, and immune systems (Sheng et al., 2021).
Prolonged stress is causing severe damage to the balanced equilibrium of the body’s
systems. It is said that too much cortisol production can disable the immune system, raise
people’s blood pressure, and generate chronic diseases. Chronic stress, in and of itself, may be a
factor in the depletion of necessary resources such as neurotransmitters and antioxidants
exacerbating the body’s incapacity to cope with stress. Healing Understanding the biological
systems that lead to stress is key to finding the right way to manage it and hence reduce the
damage that it causes (Chu et al., 2024).
Psychology and Immunity
The connection between psychosocial factors and immune function is a complex area that
scientists need to investigate. Research indicates that moods can influence our body’s various
systems, including the immune support system. During a stressful event, the immune system
becomes so weak that the systems fail causing the infection to take over, while on the other end,
the people with positive emotional states like optimism will have a strong performing immune
system. The proposed mechanisms through which the psychological elements change the
behavior of the immune system still are under ongoing investigation (O’Connor et al., 2021).

Apart from its influence on various infectious diseases, psychology is also related to the
progression and development of some minor as well as severe chronic diseases. Especially,
irritable bowel syndrome and psoriasis are the ones that are the most likely to occur because of a
psychological basis. In addition, psychological interventions can be utilized to deal with chronic
diseases such as cancer and heart diseases. These results call for the consideration of both
physiological and psychological factors in the getting of human health (Henriques & De Sousa
Loura, 2023).
