Very simply stated: Stress causes an increase in the hormone cortisol. Cortisol is a glucocorticoid steroid and has a supressive effect on the immune system, as do all glucocorticoid steroids (ex. dexamethasone). They suppress the inflammatory process which is critical in a properly functioning immune system.
The ways in which the immune system is suppressed by glucocorticoids is EXTREMELY complex, but a simple way to put it is that it keeps white blood cells from doing their job and keeps them from communicating with other white blood cells.
Under stress your body releases stress hormones such as cortisol, adrenaline, ect. This hormone release is natural, but it needs to be kept in balance. Under chronic stress your brain does not tell your body to turn off the release of these stress hormones. These stress hormones bind to the immune cells that aid in your immunity. This inhibits your immune cells from functioning properly. Thus allowing pathogens, toxins, and other harmful substances to effect the body. In short your body cannot fight off the threats if the immune cells are impaired. There is much more information on the subject. This is just one instance.
Stress causes the body to release cortisol, which has an inhibitory effect on the cells of the immune system. This can cause the body to have a more difficult time addressing and clearing infections with pathogens.
The sympathetic nervous system, active under stress, suppresses the activity associated with the functioning of the immune system. For example, the creation of antibodies takes place at a greatly reduced rate. If stress is sustained for too long it will have adverse effects upon one's physical and emotional well-being. Things that can happen include adrenal exhaustion, weakened immune system, tendency to be susceptible to catching contagious illnesses, a weakening in the body's ability to fend off cancer, decrease in reproductive abilities, decrease in cognitive skills, exhaustion, exacerbation of existing health conditions, heart troubles, and eventually death if the source of the stress is not dealt with. This is one of the reasons it needs to be taken seriously: our bodies were not meant to sustain the emergency state of high preparedness (fight-or-flight) for long intervals of time! Something's gotta give.
It may form Pathological Fatigue.
Stress, anxiety, and panic weakens the immune systemβs ability to respond to invaders, leaving us more vulnerable to infections. The cells of the immune system (and other body systems) are unable to respond normally and produce levels of inflammation which increase the risk of further health issues.
Prolonged stress can cause biochemical imbalances that weaken the immune system and invite serious illness.
Chronic or prolonged stress often results in increased blood pressure and lowering of the immune response. This, in turn, increases the stressed persons chances of becoming more susceptible to illness.

Prolonged or excessive stress.
Prolonged stress can lead to a range of physical and mental health issues such as anxiety, depression, high blood pressure, weakened immune system, and increased risk of heart disease. It can also negatively impact sleep, digestion, and overall well-being. It's important to manage stress through healthy coping mechanisms and self-care practices.
Exposure to asbestos will likely compromise the immune system because of the long-term stress to the body. The test for asbestos exposure does not affect the immune system.
The impact of prolonged psychological stress on the body causes cell aging and influences disease processes
Stress from finals can have a great affect on your immune system. When your immune system is suppressed colds can be frequent.
NO, protein can help strengthen the immune system. When the immune system is healthy then you may not get as many cold sores. Common triggers for cold sores are, being out in very hot or cold weather for long periods of time, prolonged sun exposure and lowered immune system due to illness or stress.
Psychoneuroimmunology is the study of how psychological factors, such as stress and emotions, interact with the immune system and the nervous system. This field explores how these interactions can affect overall health and well-being.
Prolonged stress begins to wear the body down over time. The body is then unable to effectively fight illness and disease.
