Pollen allergy is one of the most common causes of allergic rhinitis. It most often occurs during spring and summer, when pollen concentrations in the air are at their highest, and symptoms include sneezing, nasal congestion, itchy eyes, and fatigue. An effective approach involves not only relieving symptoms, but also combining allergen avoidance, appropriate therapy, and support for the immune system.
A pollen allergy occurs when the immune system mistakenly recognizes harmless particles from the environment as a threat and activates a defensive response.
Pollen grains are microscopic, lightweight, and easily carried through the air, which means they can travel long distances from their source. Because of this, exposure is not limited only to the immediate surroundings.
When the body comes into contact with an allergen, IgE antibodies are activated and histamine and other mediators are released, triggering an inflammatory reaction and causing symptoms (WAO; ACAAI).
After the first exposure, so-called sensitization may occur — the body “remembers” the allergen, so each subsequent exposure can trigger a faster and more intense reaction.
Genetic predisposition also plays a significant role — children whose parents have allergies are at a higher risk of developing similar reactions.
It is important to understand that this is a recurring seasonal condition, but with the right approach it can be successfully managed.

Allergic rhinitis affects a large part of the population — it is estimated that around 10–30% of adults and up to 40% of children have some form of allergic rhinitis (WAO; EAACI).
In the majority of cases of seasonal allergic rhinitis, pollen is the main trigger of symptoms.
Pollen allergy season usually begins as early as March and can last until late autumn, depending on the types of plants and weather conditions.
An additional problem is posed by climate change and air pollution, which prolong flowering seasons and increase allergen concentrations, especially in urban environments.

Different plants release pollen at different times of the year, which is why allergy season occurs in several phases.
In some individuals, so-called cross-reactions occur, where the body reacts to several different allergens due to similarities in their structure.
Interestingly, plants pollinated by insects are less likely to cause allergies because their pollen is not adapted for airborne spread.
The intensity of symptoms depends on pollen concentration, weather conditions, and individual sensitivity.
Symptoms of pollen allergy often resemble those of a common cold, but there are key differences — they last longer, occur seasonally, and are usually not accompanied by fever (WAO; ACAAI).
The most common symptoms include:
These symptoms occur as a result of the release of histamine and other inflammatory mediators, which cause swelling of the mucous membranes, increased mucus production, and irritation of nerve endings (WAO).
In children, symptoms can additionally affect sleep quality and daily functioning. Research shows that allergic rhinitis may be associated with sleep disturbances, reduced concentration, and poorer school performance, especially during the peak pollen season (EAACI).
It is important to recognize the pattern — if symptoms recur every year during the same period and last longer than a typical cold, there is a high probability that it is an allergic reaction rather than an infection.

The diagnosis is made by a doctor or allergist through a combination of medical history and testing.
The process usually begins with an analysis of symptoms and their seasonal occurrence.
The most common methods include:
A prick test provides quick information about reactions to allergens, while laboratory tests allow for more precise identification of the trigger.
One advantage of blood tests is that they can be performed without interrupting therapy, which is important for individuals with severe symptoms.
An accurate diagnosis enables a targeted approach and better symptom control during allergy season.
Although pollen is the main trigger of allergic rhinitis, many external factors can further intensify symptoms and prolong their duration.
One of the key factors is a high concentration of pollen in the air, which directly affects the intensity of the allergic reaction. During the day, pollen concentration is not constant — it is usually highest in the early morning and evening, as well as during dry and windy days.
In addition, air pollution plays a significant role. Studies show that pollution particles can intensify allergic reactions by further irritating the mucous membranes and facilitating allergen penetration (EAACI).
Dry air, especially indoors during the heating season, additionally dries out the nasal mucosa and makes it more sensitive to allergens, which can lead to more severe symptoms.
It is important to emphasize that these factors often occur simultaneously — and it is precisely their combination that can significantly increase symptom intensity and make them harder to control.

A modern approach to allergies involves combining several strategies that work together.
Although pollen cannot be completely avoided, exposure can be significantly reduced by:
Depending on symptom severity, treatment may include:
Therapy should always be prescribed by a doctor.
An increasing number of modern studies suggest that allergic reactions are not caused only by external factors, but also by the way the immune system responds to them (Weidinger & Novak, Lancet).
Omega-3 fatty acids (EPA and DHA) play an important role in reducing inflammation and regulating immune response (Niseteo et al., Nutrients, 2024).
Gamma-linolenic acid (GLA), found in blackcurrant oil, is involved in the synthesis of anti-inflammatory eicosanoids and contributes to the stabilization of the body’s barrier functions (Gamma-linolenic acid, Dihommo-gamma linolenic, Eicosanoids and Inflammatory Processes).
Vitamin D also affects immune system modulation, and its deficiency has been associated with more pronounced allergic reactions (The role of vitamin D in allergic rhinitis).
For this reason, modern practice increasingly uses an integrated approach which, in addition to standard therapy, includes nutritional support aimed at long-term stabilization of immune response.
In this context, formulations that combine omega-3 fatty acids, GLA, and vitamin D3 may provide useful support, especially for children with pronounced or long-lasting symptoms during pollen season.
This approach does not focus only on temporary symptom relief, but also contributes to better long-term resilience of the body to allergens.

Pollen allergy in children often affects not only physical symptoms, but also daily functioning and development.
In addition to typical symptoms (sneezing, nasal congestion, itchy eyes), children often experience:
Due to chronic airway irritation, some children may also experience more frequent sinus and ear infections, as well as worsening asthma symptoms if asthma is already present (EAACI).
It is important to note that children often cannot clearly describe their symptoms, so allergy-related discomfort may manifest through behavior — nervousness, restlessness, or reduced interest in activities.
Parents play a key role in recognizing patterns (seasonal recurrence of symptoms), seeking medical advice on time, and consistently following the recommended therapy.
Early intervention and continuous symptom management can significantly improve a child’s quality of life during pollen season.

Pollen concentration in the air varies significantly throughout the day and largely depends on weather conditions. Understanding this pattern can help with planning daily activities and reducing exposure.
Pollen levels are usually highest:
In contrast, after rainfall pollen concentration temporarily decreases, which may provide short-term relief.
During periods of increased pollen concentration, it is recommended to limit time spent outdoors, especially for children and individuals with pronounced symptoms, and to plan activities during parts of the day when pollen levels are lower.
Completely avoiding pollen is not possible, but exposure can be significantly reduced through proper habits.
Recommended measures include:
While driving, it is recommended to keep windows closed and use filtered ventilation systems.
In addition, avoiding drying laundry outdoors can reduce the amount of pollen brought into the home, while pets may also carry allergens indoors, making their hygiene important as well.
These habits can significantly reduce the overall allergen burden on the body and make daily functioning easier during allergy season.
Managing pollen allergy requires a combined and long-term approach, as it is a condition that recurs from season to season.
The best results are achieved through a combination of:
It is important to emphasize that no single measure is sufficient on its own — the benefit comes from their combination.
Consistency is key, because only regular and long-term application of these principles leads to more stable results and reduced symptom intensity.
Although pollen allergy may seem like a seasonal problem, its impact on daily life can be significant.
With timely diagnosis, proper therapy management, and the introduction of preventive measures, it is possible to significantly reduce the frequency and intensity of symptoms.
Modern approaches increasingly involve combining symptomatic therapy with long-term support for the body, with the goal of achieving better control of allergic reactions.
In this way, both children and adults can lead a higher-quality and more active life even during pollen season.
No. An allergy is an immune reaction to a specific allergen, while histamine intolerance occurs due to impaired histamine breakdown.
Symptoms may decrease with age, but the condition often still requires management and control.
No, allergies are not contagious.
Omega-3 may help reduce inflammation and alleviate symptoms.
Allergies last longer, are not accompanied by fever, and usually occur seasonally.
Most commonly in the morning and evening, as well as during windy days when pollen spreads more easily through the air.
Rain may temporarily reduce pollen concentration in the air, but pollen levels can rise again after the rain stops.
Allergic rhinitis is usually not accompanied by fever and occurs seasonally, while sinusitis often includes sinus pain, pressure, and thicker nasal discharge.

TL;DR – Quick answer A sudden allergy can appear even in people who previously had no symptoms at all. The most common symptoms include sneezing, rash, itching, skin redness, watery eyes, and difficulty breathing.
TL;DR – Eczema in children Eczema in children (atopic dermatitis) is a chronic inflammatory skin condition that affects up to 20% of children and most commonly begins during the first year of life. The main cause is a damaged skin barrier and an increased inflammatory response of the body.
Atopic dermatitis is a chronic inflammatory skin condition that most commonly occurs in early childhood and is associated with impaired skin barrier function and immune dysregulation. Scientific evidence suggests that certain nutrients, such as vitamin D, omega-3 fatty acids (EPA and DHA), and gamma-linolenic acid (GLA), play an important role in maintaining normal skin and immune function. Nutritional support may represent a complementary part of a comprehensive skin-care approach in children with atopic dermatitis.
