Allergies are a result of an abnormality exhibited by the immune system, which involves an intense response carried out by immune cells against a particle that is not dangerous for the human body.
What Are Allergies?
What are allergies? They are a form of irritation provoked by chemical reactions that are caused by agents to a host.
In layman’s language, this refers to a disorder of the ’s immune system that brings about an exaggerated reaction of the body when it gets into contact with foreign substances which are seemingly harmless.
These foreign substances can be chemicals or even environmental conditions. The agents causing the reaction or irritation are called allergens.
The allergens take many forms meaning that there are many forms of allergies and the reaction produced by the body is referred to as an allergic reaction.
Now, let us look at the most common allergies that have an effect on most people:
Very many individuals have sensitive nostrils that even semi-microscopic particles cause an irritation.
These tiny particles can range from pollen grains, smoke particles, molds, and house dust just to mention a few. However, those people who are allergic to dust often sneeze helplessly when they come into contact with dust particles.
Basically, the sneezing stops when dust particles are expelled completely from the respiratory system. Conversely, in some cases the sneezing persists even after the dust particles have been expelled.
In such occasions, we come across a persistent allergic reaction that continues for a while.
In some instances, those persons who are allergic to dust may experience red or itchy eyes, an itchy or running nose, respiratory problems, and sinus congestion when they come into contact with dust.
In addition, people allergic to dust should avoid exposure to dusty areas or streets, the use of perfumes, and should avoid using carpets.
They should also use air purifiers to dust their homes to keep them safe from dust allergies.
What are allergies of the skin? Basically, they may be caused by a number of allergens ranging from lotions, food, radioactive waves, direct contact with insect bites or stings, animal fur, some plants, exposure to latex, direct exposure to sunlight and dust among others.
Some of the symptoms of mild skin allergies include discoloration, swelling, and itchiness on the affected area on the skin.
In most cases, the effect of that allergic reaction is exacerbated when you scratch the irritated area of the skin.
You should not scratch the irritating area since this paves way for bacterial infections especially if during the act of scratching damage the skin leaving small wounds or lacerations.
You can relieve a skin allergy by applying corticosteroid cream.
However, if you have an allergy to this particular cream, then you should consult a dermatologist who will advise you on the most appropriate treatment and medicine.
Those people who have sensitive skin, especially those with low melanin content, should avoid direct exposure of the skin to sunlight.
The way the human body was created is unique and it reacts differently to different chemicals.
This means that people react differently to different chemicals.
Many people are allergic to crustaceans such as crabs and pawns but the most common of all cases of chemical allergies are those allergies caused by food.
You will find that some people are allergic to some or all sources of protein; some are allergic to tomatoes, while others are allergic to colored foods.
Those who are allergic to colored foods are actually allergic to the chemical that makes the food colored. Some people are also allergic to alcoholic substances and wine.
Again, the allergic reactions are of varying degrees and sometimes it can be fatal, particularly if that allergen is above the person’s upper threshold of tolerance for that specific substance.
In conclusion, “what are allergies? “is a question asked by many individuals. Nevertheless, having known what allergies are, you should avoid the environmental conditions or substances which you are allergic too.
But still, you can use supplement boosters which will be of great help to you. Some nutritional supplements actually relieve allergies.
Recent research has shown that bioflavonoids, calcium, bromelain, licorice, and magnesium help alleviate the effect of an allergy.
However, quercetin is in fact a bioflavinoid that regulates the release of histamine. Quercetin is found in strawberries and also helps reduce the severity of the allergic reaction.
Lastly, it is important that you visit the doctor before taking medication for any type of allergy to avoid further complications.
A similar response is necessary when the body is “attacked” by virus species or bacteria, which is useful to eliminate the infection and heal the body.
In the case of allergies, the immune response is completely unnecessary since the particles that initiate it are completely harmless.
The particles may be protein molecules found in tree or grass pollen, pet hair, food sources or artificial materials and fabrics.
The immune cells make physical contact with these harmless proteins, but they treat them as if they were dangerous and intrusive, which leads to the initiation of the massive immune response.
What are the most common allergies, symptoms food allergy and how to find effective remedies against them?
The most common allergies are hay fever, food allergies and allergic reactions caused by pets.
Occasionally, fabrics and medications may also cause allergies, but they tend to be less frequent in comparison to these three allergies.
Hay Fever is Becoming the Number One Form of Allergy Due to Climate Change
Hay fever season starts in spring when the plants start to blossom, which results in the accumulation of high amounts of pollen in the air.
This pollen contains protein particles that are able to generate an abnormal hypersensitivity of immune cells, which respond dramatically by causing allergy symptoms.
Hay fever is also known as allergic rhinitis because its main symptom involves the inflammation and obstruction of the nasal airways.
This form of allergy becomes the champion among other allergy varieties because the global climate change, which consists in the slow elevation of the air temperature, leads to a longer and more intense pollen period.
Due to global warming, plants start to release pollen considerably earlier than before, and the concentration of pollen in the air is substantially higher.
These circumstances create a hypersensitivity in many individuals who have a genetic pattern that makes them vulnerable to allergies.
Once the immune cells of the affected individuals make contact with the inhaled pollen, they generate a massive inflammation response and release biologically potent molecules, such as histamine.
The symptoms of hay fever are nasal congestion accompanied by watery nasal discharge, teary eyes, itching, and, in rare cases, breathing impairment due to the constriction of the air passages.
The treatment of hay fever consists in the avoidance of pollen-rich locations, nasal decongestants to relieve the bothersome breathing obstruction and antihistamines to block the abnormal histamine response.
How to Treat Pet Allergies
Most people believe that pet hair is to blame for the symptoms of pet-induced allergies. However, scientific research contradicts this popular view.
The proteins that are able to sensitize the immune system of genetically predisposed individuals are found in the saliva and dry skin fragments that come from pets.
Although pet hair is certainly an unpleasant presence on rugs, furniture and clothes, it is harmless when it comes to pet allergies.
However, the presence of pet hair can indirectly signal the presence of minute saliva residue or dead skin fragments in the same area of the house, which requires a timely and thorough removal through solid cleaning procedures.
However, cleaning may not solve the allergy problem entirely for some individuals, so they may be advised to avoid living with their pets.
Pet allergies can generate unpleasant symptoms that may range from a mild skin rash or an excessive production of tears through eye irritation to severe bodily swelling, breathing impairment due to constriction of the bronchi and even a collapse of the blood pressure as part of anaphylactic shock.
Severe allergy symptoms are rare, but one should not take any chances and seek immediate treatment for pet-induced allergic reactions.
Immunotherapy, which consists of injections with a small but gradually increasing allergen dose, may represent a cure for pet allergies.
It works by reducing the hypersensitivity of the immune cells by exposing them to small amounts of pet allergens until an adaptation response is achieved.
Immunotherapy can successfully treat pet allergies if administered for several months, depending on the individual tolerance and immune adaptive capacity common dog allergies can be treated.
Allergic reactions to food
Allergic reactions to food are also among one of the most common allergies, especially in children.
Egg allergy is a common problem in kids, but more than half of them will outgrow this health issue and become symptom-free upon reaching the adult age.
Peanut allergies may require special medical attention and more precautions since they are particularly “famous” for causing severe symptoms, such as anaphylaxis and breathing impairment due to swollen and constricted airways.
