Question

Как возникла аллергия, краткий ответ!!!

Answer 1

Термин "аллергия" используется для неоправданно сильной реакции организма на какое-то вещество, поступающее извне. Человеческий организм обладает сильной системой защиты от внешних агрессивных факторов - иммунной системой. Чуждые вещества - антигены - при попадании внутрь организма, провоцируют реакцию иммунной системы, которая начинает вырабатывать особые антитела для нейтрализации данного антигена. Эта реакция необходима в таких случаях, как попадание в организм вируса или инфекции. В случае же аллергии иммунная система начинает активно реагировать на вещества, безвредные для обычного человека, называемые аллергенами. 

Answer 2

Аллергия возможна при попадении частиц грязи в очищенную кожу

Answer 3

The Origins of Allergies

Allergies are a common health condition that occurs when the immune system reacts to a substance that is normally harmless. This immune response can cause a range of symptoms, such as sneezing, itching, watery eyes, and skin rashes. The exact cause of allergies is not fully understood, but there are several theories on how they develop.

One theory is the hygiene hypothesis, which suggests that increased cleanliness and reduced exposure to certain microorganisms in early childhood may lead to an overactive immune response to harmless substances later in life. This hypothesis proposes that a lack of early exposure to bacteria and viruses weakens the immune system's ability to distinguish between harmful and harmless substances, leading to an increased risk of developing allergies.

Another theory is the genetic predisposition theory, which suggests that certain individuals may have a genetic susceptibility to developing allergies. If a person has a family history of allergies, they may be more likely to develop allergies themselves. However, having a genetic predisposition does not guarantee that a person will develop allergies, as environmental factors also play a role.

Environmental factors, such as exposure to allergens, can trigger the development of allergies. Common allergens include pollen, dust mites, pet dander, certain foods, and insect venom. When a person with a genetic predisposition is exposed to these allergens, their immune system may produce an exaggerated response, leading to allergy symptoms.

It is important to note that allergies can develop at any age, and some individuals may develop allergies later in life, even if they did not have them as children. Additionally, the specific triggers and mechanisms behind allergies can vary from person to person.

In summary, the exact cause of allergies is still not fully understood, but theories such as the hygiene hypothesis and genetic predisposition provide insights into their development. Environmental factors, such as exposure to allergens, also play a role in triggering allergic reactions.
