Allergy to Dust
Scientists estimate that the air in our homes is 4 times dirtier and 8 times more toxic than the air outside. It is poisoned by dust – a mixture of the smallest particles of textile fibers, soot, pollen and mold spores, dead skin, insect remains and their waste. Many dust components cause allergies. This applies in particular to the excrement of microscopic saprophyte mites that live in any home. Few people suspect that millions of these creatures live near us.
Mites can only be seen under a microscope because they are so small. Saprophytes are located on dead skin particles, as well as feather padding from old pillows. The favorite location of these insects is bedding, upholstered furniture and carpets.
The mites themselves are not dangerous – they do not bite, do not cause skin diseases, do not tolerate infection. However, the tiny particles of dead mites, and especially their excrement, are the strongest allergen.
Allergy to Mold
It turns out that mold fungi like to multiply in dead plants, so the fallen leaves, compost, and the grass under the snow layer is an ideal place for mold reproduction.
Mold is a fungus that can grow and multiply both outdoors and in the house. There are thousands of species of mold fungi, which are often strong allergens. The fact is that spores and fragments of fungi are easily transported through the air, getting into our airways, causing responses in some people.
Manifestations of allergies can be different: rhinitis, conjunctivitis, atopic dermatitis or eczema. Symptoms depend on which organ responds more: eyes, skin, nose, lungs.
With timely and proper treatment, unpleasant reactions disappear but if you do not get rid of the source of allergy in time and start the painful manifestations, the child may develop bronchial asthma.
According to statistics, in 15% of children with asthma, hypersensitivity to mold fungus allergens is detected. That is, asthma can be triggered by contact with the mold. But even if a child has not developed such a serious disease as asthma, the baby’s body becomes vulnerable and subject to allergic reactions to various stimuli.
Allergy to Blooming
The main problem of allergy is pollinosis, the body’s response to pollen. Important: if we are talking about the flowering of trees, we mean that the buds have opened. The snow may still be outside, but pollen is already in the air.
There is a syndrome of “thawing snow” – the symptoms of allergic rhinitis appear when the snow melts. People associate this condition with reagents, but it is more likely that this exacerbation is caused by everything that is released by snow – mold and animal feces. People with allergies to cats and dogs may experience allergy symptoms because the concentration of animal allergens in the air increases.
Allergy to Animals
It is estimated that about 15% of all people are affected by this disease. In children, this form of allergy is more common than in adults and is more severe.
The most common allergy is an allergy to dog and cat hair. However, there may be allergies to the fur of other animals, for example, rodents, which are also often kept at home, as well as allergies to wool products, especially those made of camel and sheep wool.
For a long time, it was believed that allergy to wool was associated with the very hair of the animals of which it is composed. But then it turned out that it was not true. Animal hair may also contain allergens, however, most often, not those substances that are directly contained in the hair, but substances that are secreted by the body of pets are responsible for allergies.
As a rule, these are proteins contained in the urine, feces, secretions of sebaceous and sweat glands, pieces of the epidermis (upper part of the skin). Animal dander is simply the object that successfully absorbs these allergens. Thus, instead of allergy to animal hair, most often a person is faced with the so-called epidermal allergy.
As practice shows, there are no products able to trigger an allergy. However, there are a number of products, the prevalence of allergies to which is much higher than others.
What foods are most allergenic:
- hazelnuts (this group includes not only hazelnuts but also walnuts, cashews, pistachios and some other exotic nuts);
- fish and seafood;
Sometimes this list includes products such as citrus, chocolate, honey and cocoa. But these products are most often responsible for the occurrence of false rather than true allergic reactions, the main cause of which is their excessive use.
There is also a cross-type allergy, where there are reactions associated not with a specific product, but with a whole class of related products. For example, an allergy to wheat proteins can lead to an allergy to all types of cereals, an allergy to shrimp results in an allergy to crab meat, etc.
Allergic reactions to food additives can be distinguished as a separate group – supplementary components contained in most products produced by the food industry – preservatives, flavor enhancers, dyes, stabilizers, etc.
Allergy to Sun (Solar Allergy)
Allergy to the sun (photodermatosis) is an excessive immune response of the body to exposure to sunlight. Doctors strongly recommend starting treatment of sun allergy as early as possible. If staying under the sun causes even the slightest allergic reaction, you should immediately take all precautions by contacting an allergist.
According to medical statistics, the number of reported cases of allergy to the sun increases annually. Note that solar allergies do not necessarily occur in a chronic form. Perhaps after treatment is prescribed, the symptoms of allergy will disappear and will never disturb you again.
The sun’s rays themselves are not triggers, however, can make the human body begin to accumulate substances that cause an allergic reaction. Often, solar allergies are observed in young children, because their immune system is not yet able to cope with the overloading.
Allergy to Cockroaches
According to one medical publication, an estimated 10 to 15 million people in the United States are allergic to cockroaches (the University of California at Berkeley Wellness Letter). Allergy sufferers from cockroaches have skin irritation, hay fever, or asthma symptoms. Up to 80% of all children with asthma are particularly sensitive to cockroaches. Cockroaches are found not only in dirty kitchens. They can even appear in the cleanest kitchen. It is estimated that there may be as many as 1,000 undetected insects per insect that have spread throughout the house. One pair in one year can give birth to 100,000 insects.
Allergy to Insect Bites
In most cases, the appearance of a hypersensitivity reaction is observed after the bites of Hymenoptera biting insects. The poison that enters the body contains a significant percentage of high molecular weight protein enzymes, basic peptides, biogenic amines, which cause a number of pathological reactions. Also, the bite of such insects marks the occurrence of a local reaction caused by the expansion and enhancement of the permeability of the blood vessels walls. It greatly enhances the negative impact of the poison that entered the body. When biting mosquitoes, gadflies and midges release a pronounced toxic-allergic effect which penetrates under the skin.
Allergy to Peanut
An allergic reaction to peanut beans is often observed in children. An allergic reaction may occur not only after eating nuts in its pure form. Food products containing minimal amounts of peanuts can also provoke signs of hypersensitivity. In addition, symptoms can occur when the smell of peanuts is inhaled, when cosmetics are used with the addition of peanuts, and even when you touch these beans.
Allergy to Medications
Drug allergies can occur as a complication in the treatment of a disease, or as an occupational disease as a result of prolonged contact with medications. According to statistics, among the urban population drug allergy occurs most often in women aged 31-40 years. The main reasons for the development of allergy to drugs are:
- hereditary factors;
- the presence of other types of allergies;
- long-term use of drugs;
- simultaneous use of a large number of different drugs.
An allergic reaction to medications may also occur from an overdose of drugs (in this case, it is a pseudo-allergic reaction).
Almost all medications can provoke allergic reactions. In most cases, the cause of allergic reactions are antibiotics, local anesthetics, nonsteroidal anti-inflammatory drugs, etc. Once appeared, drug allergies will occur again and again when you take the very medicine.
