Hay fever is a form of allergic disease called allergic pollen rhinitis, also known as seasonal allergic rhinitis…

Every year when spring begins, besides the excitement of entering a hot spring with a strong revival of all kinds of plants and flowers after a long winter hibernation, for many people it is the beginning of a long time of year. often miserable, tired or sick, and the cause is simply an allergy to pollen from certain plants. This is a form of allergic disease called allergic pollen rhinitis, also known as seasonal allergic rhinitis or hay fever. And, in this talk, I will refer to it as seasonal allergic rhinitis.


When can seasonal allergic rhinitis symptoms appear?

In fact, seasonal allergic rhinitis (hay fever) usually begins in the spring, when plants flower and certain allergenic plants release their pollen into the air. Then, the other allergens release their pollen during the summer and can last until mid-October each year.
In some patients, symptoms of seasonal allergic rhinitis worsen at certain times of the year, in the spring, summer or fall. However, there are also cases of symptoms throughout the year due to the patient’s sensitivity to indoor allergens (dust mites, cockroaches, mold, dog hair, cats, etc.).

Symptoms of seasonal allergic rhinitis (hay fever) usually appear immediately after a patient’s exposure to a specific allergen, these symptoms include:

  • If a person with seasonal allergic rhinitis has more asthma, the asthma will get worse with each allergy.
  • Clear and thick runny nose
  • stuffy nose, itchy nose, ears, palate or throat
  • Watery or itchy eyes, redness or swelling of the eyelids
  • Repeated coughing and sneezing
  • Feel the sinus pressure and pain
  • Headache
  • Swollen eyes and dark circles below due to a blocked nose and sinuses
  • Reduced or lost smell and taste

Distinguishing seasonal allergic rhinitis from colds:

Seasonal allergic rhinitis (hay fever) is easily mistaken for a cold because the symptoms are somewhat similar.

  • However, seasonal allergic rhinitis can last several weeks longer than a cold and usually does not cause a markedly high fever.
  • The fluid or sputum from seasonal allergic rhinitis is usually more liquid and clearer than the cold.
  • In particular, symptoms such as itchy eyes, nose, throat and skin are only common with seasonal allergic rhinitis and not with the common cold.
  • Besides the direct effects of the symptoms of seasonal allergic rhinitis mentioned above, its side effects also greatly affect the quality of life of the allergic person and their family.
  • From spring to autumn, daily activities or sports, leisure and professional performance at work or at school can be disrupted by fatigue, sleep disturbances, distraction, irritability, irritability etc. …

Diagnostic tests for seasonal allergic rhinitis:

To diagnose seasonal allergic rhinitis (hay fever), in addition to the above clinical symptoms, doctors may prescribe 2 more important tests as follows:

  • Percutaneous skin test: small sample of various allergens is injected into the patient’s skin, after about 20 minutes of assessing an allergic reaction, if there is an allergic reaction that area will develop a rash or urticaria.
  • Allergen-specific immunoglobulin E (IgE) antibody test: take blood from the arm vein to check for a specific allergen that is suspected


Wrong and outrageous responses to harmless immune system agents

Seasonal allergic rhinitis has seasonal and cold-like symptoms like runny nose, congestion, sneezing, and sinus pressure.
However, it is not caused by a virus such as the flu, but seasonal rhinitis occurs when a person’s immune system reacts allergically to allergens such as pollen or certain allergens. Other types such as body hairs ‘animals, mites and mold spores, grass, etc. .. as mentioned above that other normal people do not have these reactions.
Seasonal allergic rhinitis can have a great impact on the lives of patients, not only reducing productivity and daily activities, but also often making them uncomfortable and unhappy, and even negative mental effects.

The incidence of seasonal allergic rhinitis:

  • The incidence of seasonal allergic rhinitis varies from one locality to another, but in Quebec alone in Canada, this rate is quite high, up to 20% of the population and is mainly caused by pollen.
  • Although seasonal allergic rhinitis can start at any age, many cases worsen in childhood and reach pre-adulthood, then gradually decrease.


Prevent seasonal allergic rhinitis:

There are a few simple and effective steps you can take to help reduce the symptoms of seasonal allergic rhinitis (hay fever):

  • Avoid going out when pollen concentrations are higher, that is to say between 7 am and 1 pm in hot or dry weather and especially in very windy weather.
  • If possible, keep car windows and doors securely closed.
  • Use a recycled indoor air conditioning system or a system with pollen filters.
  • Wear a mask and sunglasses that cover your eyes when you go out.
  • Change your clothes as soon as you get home and be careful not to dry outside.
  • Avoid engaging in activities that promote the spread of pollen, such as mowing the lawn or cleaning up dead leaves.
  • Avoid going to places with high pollen concentrations and avoid exposure to other irritants, such as cigarette smoke.
  • And if possible, remove your allergenic plants from your garden

Treat seasonal allergic rhinitis:

Medical treatment may include the following:

  • Nasal corticosteroids: help prevent and treat rhinitis, itchy nose, and runny nose
  • Oral corticosteroids: help to reduce allergy symptoms effectively, but note that if used long-term, there will be many side effects.
  • Antihistamines: Helps relieve itching, sneezing and runny nose
  • Decongestants: are vasoconstrictors in the nose, helping to reduce congestion caused by colds and allergies
  • Nasal wash: is an effective treatment, helps flush allergens from the nose and reduces symptoms.

Essential oil therapy to prevent and treat seasonal allergic rhinitis

In addition to the above drug therapies, patients can also apply essential oil therapies to effectively prevent and treat acute or chronic hypersensitivity states. For each specific case, the patient can choose suitable essential oils such as antiallergic oils with essential oil of geranium, helichrysum; for antihistamines with lavender essential oil, chamomile essential oil, and for improving the immune system in general, with basil oil, rosemary oil, etc. Preparation and application is relatively simple, you can easily learn specific items and apply them on yourself, or your loved one

Other therapies to prevent and treat seasonal allergic rhinitis

Finally, while there are many other measures that can help you prevent and aid in the treatment of seasonal allergic rhinitis (hay fever) like diets, juice recipes etc … which maybe I will talk about more carefully. than in another conference. Here I want to highlight one method that anyone can apply which is physical training. This is always a necessity and can be flexibly applied depending on individual circumstances. Additionally, the benefits of physical training bring each of us not only in one aspect, but also an overall benefit, both physically and mentally.
