Allergies and the Immune System: How Are They Connected?

Allergies and the immune system: how the body reacts to allergens

Allergies and the immune system are closely connected, because an allergic reaction involves the immune system. When the body comes into contact with a particular allergen, it may react to a substance that is completely harmless to most people, such as pollen, household dust, certain foods or other substances in the environment. 

This means that having an allergy does not necessarily mean that the immune system is “weak.” It is a specific type of immune response to a particular substance.

How Does the Immune System React to Allergens?

The immune system constantly identifies substances that enter or come into contact with the body. If a particular substance is recognised as an allergen, a specific immune response may develop.

Some allergic reactions involve IgE antibodies. When the body encounters the same allergen again, substances such as histamine may be released, contributing to common allergy symptoms. 

The response is highly individual. A substance that acts as an allergen for one person may cause no noticeable reaction in another.

Why Are Allergies Often Seasonal?

One of the clearest examples is pollen. Different plants release pollen at different times of the year, so pollen levels in the air change from month to month. This is why seasonal allergies often return at roughly the same time each year. 

How much time a person spends outdoors can also matter, as well as whether windows are frequently left open, whether walks take place on dry and windy days, or whether more time is spent in areas with high pollen exposure.

If you already know which allergens affect you, it becomes easier to take them into account when planning everyday activities during pollen season.

What Should You Consider During Pollen Season?

It can be useful to check the pollen forecast and pollen calendar, change clothes after spending a long time outdoors and take current pollen conditions into account when ventilating your home.

Keeping a familiar daily routine also matters: getting enough sleep, eating regularly, drinking enough water and making time for physical activity.

If an allergic reaction appears for the first time, changes noticeably or becomes significantly stronger, it is advisable to consult a healthcare professional to determine the possible cause.

FAQ

Do allergies mean you have a weak immune system?

No. Allergies are associated with a specific immune response to a particular allergen rather than simply meaning that a person has a “weak immune system.” 

What is an allergen?

An allergen is a substance that can trigger an allergic reaction in a person who is sensitive to it. Common examples include pollen, certain foods, household dust and other substances found in the environment.

Why do seasonal allergies come back every year?

One reason is the pollen season. When certain plants begin releasing pollen again and its concentration in the air rises, exposure to the corresponding allergen also increases. 

How are allergies and the immune system connected?

An allergic reaction involves the immune system. In a person with an allergy, the immune system responds to a particular substance identified as an allergen.
