● When some people go to a `color{Violet}"new place"` and suddenly start `color{Violet}"sneezing, wheezing"` for no explained reason, and when they leave the place, their `color{Violet}"symptoms dissappeared"`.
● It is because those people are `color{Violet}"sensitive to some particles"` in the environment.
● The above-mentioned reaction could be because of `color{Violet}"allergy"` to `color{Violet}"pollen, mites"`, etc., which are different in different places.
● The `color{Violet}"exaggerated response"` of the immune system to certain `color{Violet}"antigens"` present in the environment is called `color{Brown}"allergy"`.
● The `color{Violet}"substances"` to which such an `color{Violet}"immune response"` is produced are called `color{Brown}"allergens"`.
● The antibodies produced to these are of `color{Violet}"IgE type"`.
● Common examples of allergens are `color{Violet}"mites in dust"`,`color{Violet}" pollens"`, `color{Violet}"animal dander"`, etc.
● Symptoms of allergic reactions include `color{Violet}"sneezing"`, `color{Violet}"watery eyes"`, `color{Violet}"running nose"` and `color{Violet}"difficulty in breathing"`.
● Allergy is due to the release of chemicals like `color{Violet}"histamine and serotonin"` from the `color{Violet}"mast cells"`.
● For determining the cause of allergy, the patient is exposed to or injected with `color{Violet}"very small doses"` of possible `color{Violet}"allergens"`, and the reactions studied.
● The use of drugs like `color{Violet}"anti-histamine"`, `color{Violet}"adrenaline"` and `color{Violet}"steroids"` quickly reduce the symptoms of allergy.
● Somehow, `color{Violet}"modern-day life style"` has resulted in `color{Violet}"lowering of immunity"` and more sensitivity to `color{Violet}"allergens"` – more and more children in metro cities of India suffer from `color{Violet}"allergies and asthma"` due to sensitivity to the environment.
● This could be because of the `color{Violet}"protected environment"` provided early in life.
