Impact Of Stress On Immune System
The link between the brain and immune system involves two main pathways: the autonomic nervous system and the-hyphophyseal-pituitary – adrenal axis. Perception of stress leads to activation of HPA system which begins with the secretion of corticotrophin releasing hormone which in turn induces the secretion of adrenocortictrophic hormone by the anterior lobe of the pituitary lobe. ACTH activates the secretion of corticoids by the adrenal cortex and catecholamines by the adrenal medulla. The catecholamines and corticoids suppress the production of IL-12 by the antigen-presenting cells which is a primary TH1 cytokine-inducing inducing stimulus. Corticoids can also exert a direct effect upon TH2 cells thus increasing the production of IL-4, IL-10 and IL-13. The end result is the predominance of a TH2 cell mediated response which would favor an allergic inflammatory response in a susceptible individual.
The CNS modulates immune system through neurotransmitters , glutamic acid), neuropeptides , neurological growth factors ), and hormones whereas the immune system can also modulate CNS function via various molecules including cytokines , chemokines and nitric oxide . Perception of acute stress stimulates the locus ceruleus which secretes noradrenalin. Noradrenalin activates the sympathetic nervous system leading to decrease production of IL-12 as described earlier.
Reaction To Food Odor Alone
Some people may have an immediate reaction when they smell a particular food that is not due to the inhalation of food particles, but rather the way that their brains process a particular smell. In this case, the reaction would not be considered a true allergy.
If someone has an allergyespecially a severe food allergyand smells that particular food being cooked, their brain may immediately register a warning. The subsequent anxiety could, in turn, lead to physical symptoms such as an increased heart rate.
Anxiety can cause the release of stress hormones and adrenaline in a “fight-or-flight response.” Sometimes these reactions can be very intense, and they can be mistaken for an allergic reaction.
When in doubt, it is crucial to assume someone may be having an allergic reaction and pursue emergent medical care as needed, rather than to think their reaction is related to anxiety and miss treating life-threatening anaphylaxis.
How Common Is Stress
Among people who had serious psychological distress in the past year, the risk of asthma is 50 percent to 70 percent higher than people without distress. Among people diagnosed with depression in the past year, the risk of asthma is also about 70 percent higher. The highest levels of stress are seen in inner-city residents, Puerto Ricans, and African Americans/blacks. Asthma rates in these groups are disproportionately high.9,13,14

Why Does The Body React To Stress This Way
When you’re stressed, your body’s cortisol levels begin to increase, leading to increased oil production that can cause acne breakouts, and revving up your body’s histamine response, or a release of inflammatory chemicals that often make you feel uncomfortable.
Unfortunately, how that histamine response results in a rash or flare-up of your other skin conditions is still unclear. “We don’t know how or why the skin responds to your stress hormones, but it’s not a direct relationship,” says Dr. Nazarian. “We may not know exactly why the trigger happens, but we know how to fix it.”

The Relationship Between Allergies And Anxiety
The relationship between allergies and anxiety is complicated and not yet fully understood. Each person’s body reacts differently, both to allergies and to anxiety, so it’s difficult for researchers to pinpoint the causes and effects. However, there are several theories to explain the relationship between anxiety and allergies.
Researchers have found that any one of these could potentially be true with regards to anxiety. But even more likely is that all of them are true to some extent and are simply more or less pertinent for different people.

Allergy To Inhaled Food When You Don’t Have A Food Allergy
Sometimes a food can be eaten with no problem, but issues arise only when small particles of it are inhaled. This is referred to as hypersensitivity to foods by inhalation. This phenomenon can occur with peanuts, cow’s milk, fish, shellfish, seeds, soybeans, cereal grains, legumes, hen’s egg, coffee, and flour. In fact, there have been several reports of steam allergy to legumes.
Typical symptoms of an airborne allergy to food particles often include runny, watery eyes, coughing, wheezing, and asthma. An anaphylactic reaction is serious and less common but can occur.
It’s important to note that kitchens and restaurants aren’t the only places where this type of allergic reaction can occur. This can be a problem for some workers who handle food products , or those who work with food additives. These people have an increased risk of developing occupational asthma.
Most exposures occur through the inhalation of dust, steam, vapors, and airborne proteins that are produced in the process of cutting, cleaning, boiling, or drying foods.

What Is A Stress Rash
A stress rash is simply a rash or issue with the skin caused by stress and anxiety.
A typical stress rash reaction is breaking out in hives, known as urticaria. These are raised, itchy bumps that appear on the infected area and can appear anywhere on the body. Along with hives, those with existing skin conditions, like eczema and rosacea, can experience more frequent flare-ups. Stress rashes are widespread, affecting millions in the United States annually.
How does it work? When cortisol levels increase in response to stress, your body’s histamine response goes into action, manifesting as puffy skin, inflammation, and overall increased oil production. This oil, for example, can cause severe acne outbreaks.
Other Causes Of Reactions
Beyond eating and inhaling food particles, it’s important to note that allergic reactions may also occur in response to skin or mucous membrane contact with even a small amount of an allergen.
It’s also worth pointing out that if you’re pregnant, your sense of smell is heightened and you may experience aversions to certain foods or food smells . Avoiding particular foods in pregnancy is generally considered to be common and normal, provided that you’re still able to eat a variety of other nutritious foods.

Emotional Physical And Social Impacts
Research has proved that stress can bring about an onset and exacerbation of hives, in addition to finding that emotional stress in particular is linked to itch intensity.
For people with both urticaria and anxiety, a vicious cycle can often occur, with stress and anxiety leading to an outbreak, which then leads to more stress. Feeling physically uncomfortable and not sleeping well due to itching or pain can also increase anxiety and stress levels. This cycle can exert a negative impact on ones emotional, physical and social functioning, highlighting the importance of stress-reducing and stress management techniques, discussed later in this slideshow.
What Are The Symptoms Of Stress
Stress can affect all aspects of your life, including your emotions, behaviors, thinking ability, and physical health. No part of the body is immune. But, because people handle stress differently, symptoms of stress can vary. Symptoms can be vague and may be the same as those caused by medical conditions. So it is important to discuss them with your doctor. You may experience any of the following symptoms of stress.
Emotional symptoms of stress include:
- Becoming easily agitated, frustrated, and moody
- Feeling overwhelmed, like you are losing control or need to take control
- Having difficulty relaxing and quieting your mind
- Feeling bad about yourself , lonely, worthless, and depressed
- Avoiding others
Physical symptoms of stress include:
- Low energy

Both Affect Each Other
The most likely scenario – as is often the case with anxiety comorbidities – is that the two are independent, but affect each other. Allergy attacks likely make anxiety worse, because they cause an even poorer quality of life and physical symptoms that may contribute to further anxiety. Anxiety makes allergies worse by altering the immune system and releasing more allergy-triggering hormones. Together, they become a cyclical problem that may not stop without the right treatment.
B Altered Immunity In Allergic Diseases
For purposes of this discussion, allergy or immediate hypersensitivity describes a series of immune based reactions occurring as a result of the induction of allergen specific IgE that binds to mast cells via high affinity FcR1 receptors. Subsequent re-exposure to the inciting allergen causes a cross-linking of the mast cells-bound IgE with activation and release of the mast cell contents such as histamine, leukotrines, tryptase, chymase, kininogenase, and heparin within 560 minutes of exposure. These mediators can induce vasodilatation and vascular leaks, causing mucosal edema, increased mucus gland secretions, nasal and/or bronchial congestion and occlusion resulting in various clinical signs and symptoms. . Late phase allergic reactions can occur six to twenty-four hours after initial exposure following the recruitment and migration of inflammatory cells like eosinophils, basophils, neutrophils, T lymphocytes, and macrophages to the target tissues . These result in more persistent symptoms. TH2 cytokines play a critical role in orchestrating ongoing inflammation.
Clinical principles for managing allergic diseases include of
Avoidance of exposure to known allergic and non-allergic triggers
Controlled exposure to allergens that cannot be totally avoided
Pharmacotherapy to treat mast cell mediated symptoms and reduce allergic inflammation
Allergen Immunotherapy for upper and lower airway disease in selected individuals

Other Tools To Fight Allergies
Allergy management should also include strategies to avoid exposure to pollen. This can include keeping windows closed, wearing a mask for yard work, avoiding going outside when pollen levels are high, and cleaning air conditioning ducts and filters.
Another important tool: stress reduction. “When you reduce stress levels and psychological stressors, you’ll feel like your quality of life has improved beyond just simply treating the allergies,” Dr. Sedaghat says.
“It’s not clear yet that stress reduction can directly reduce physical allergy symptoms, but there seems to be a mind-body connection when it comes to inflammatory diseases. So if you reduce stress, we would expect that stress hormone levels would go down, and the allergic overdrive to therefore go down as well,” Dr. Sedaghat says.

Can Stress And Anxiety Cause You To Break Out In Hives
Stress and anxiety can cause hives. For this reason, sometimes hives might be called stress hives or a stress rash.
For example, when youre under a great deal of stress, your body sends a message to its immune cells, telling them to release powerful chemicals most notably, histamine. Histamine triggers inflammation and the itchiness associated with hives.
Stress is only one of several triggers that can cause symptoms like skin rashes or hives. Other causes of skin rashes include:
Food allergens, such as peanuts, shellfish, or spicy foods
Pollen, dust, or animal dander
Irritating chemicals, such as laundry detergents
Viral or bacterial infections

Anxiety And Asthma Can Trigger Each Other
Response from Lyn Harper, MPA, BSRT, RRT:
Although anxiety doesnt cause asthma, it can certainly worsen symptoms. In fact, the two conditions can actually make each other worse. Any strong emotions can have an effect on our respiratory system and our airways and particularly so when a person has hypersensitive airways, as is the case with asthma. Strong emotions can trigger a chemical response in the body that may release histamine and leukotrienes both of which can trigger narrowing of airways. Stress and anxiety can also weaken the immune system, making a person more susceptible to viruses and illnesses that in turn lead to asthma problems.
So, if you have asthma its important to reduce anxiety as much as possible. You would certainly want to discuss options with your doctor. They may suggest an anti-anxiety medication that can be taken regularly or only when needed depending on the severity and frequency of your anxiety. If you decide to try a natural remedy, of which there are plenty, you would also want to speak to your doctor to determine what may or may not interfere with medications you already take.

It Enhances The Immune Response
Response from John Bottrell, RRT:
This is the age-old question, as asthma was — for many years — considered a psychological/nervous disorder — it was caused by anxiety and stress. This was because asthmatics were observed to be nervous or anxious. This theory was extensively studied and modified by the 1950s, and by the 1980s was changed to: “While anxiety cannot cause asthma, it can act as an asthma trigger.” Modern science has pretty much confirmed the link between asthma and anxiety. However, it also appears that anxiety neither causes new-onset asthma nor triggers asthma. What it does do is enhance the immune response responsible for asthma.
Anxiety causes stress. You are in a situation that makes you feel uncomfortable or stressed, and your body releases cortisol and epinephrine. The combination of these initially reduces airway inflammation and open airways. However, when the stressful situation continues long term — you lost your job, someone you loved passed away, you live in abject poverty — your body responds by decreasing cortisol receptors. This is fine for non-asthmatics, and might even be good. However, in asthmatics, it makes it so that they are more likely to have an asthma attack when exposed to their asthma triggers. It also makes it so their airways are less responsive to the effects of corticosteroids, making their asthma increasingly difficult to control.
