Allergies are a common health concern all around the world. They can affect people of all ages, and the symptoms can range from mildly inconvenient to life-threatening. World Allergy Day is an annual event that takes place on April 8th.

It is an opportunity to raise awareness about allergies, their causes, and their effects on people’s health.

What is an Allergy?

An allergy is an exaggerated response from the immune system to a foreign substance that is not typically harmful to the body.

This substance, called an allergen, triggers a reaction that can cause a range of symptoms such as itching, sneezing, and wheezing. Common allergens include pollen, dust mites, pet dander, and certain foods.

Types of Allergies

There are several types of allergies, and they can be divided into two main categories: seasonal allergies and year-round allergies.

Seasonal Allergies

Seasonal allergies, also known as hay fever or allergic rhinitis, are caused by allergens that are more prevalent during certain times of the year.

Common seasonal allergens include tree pollen in the spring, grass pollen in the summer, and ragweed pollen in the fall.

Year-Round Allergies

Year-round allergies are caused by allergens that are present all year round. Common year-round allergens include dust mites, pet dander, mold, and certain foods.

Year-round allergies can be more difficult to manage since the allergens are always present.
