Allergy is one of the most important causes of runny nose in autumn

Allergy or sensitivity refers to the body’s defense reaction to external and generally harmless factors, which may be mild or severe. The allergenic substance can be food or inhaled substances, which react to each in a different way in the body. The interesting point in this regard is that allergies do not only belong to spring or summer. Researches have shown that due to climate changes, the number of pollens has increased significantly in recent years, and micro-pollens and air humidity have provided the conditions for the emergence of allergies.

Allergic reactions of the autumn season are very similar to the symptoms of a cold, which should be carefully examined so that the necessary measures can be taken in this direction.

Allergies in autumn

We explained the cause of runny nose. Allergies can be caused by food factors such as nuts, seafood, dairy, wheat and some fruits. On the other hand, environmental factors such as mold, animal dander, bee stings, pollution, cigarette and tobacco smoke, and dust can also trigger allergic reactions. But the most common type of it occurs in the autumn season, generally due to pollination and mushroom spores, which we will mention below. The arrival of autumn can be the cause of your runny nose.


One of the most common causes of a runny nose in autumn is the sensitivity of the immune system to pollen in the air, which accounts for about 80% of people with allergies. Normally, pollination starts from spring and continues until the end of November. Pollens can be released into the air from grasses, birch, cypress and oak trees, ragweed, heather and weeds.


The cause of runny nose can be the fungi on the trunk and leaves of plants. The tiny spores in the mushroom are spread in space under the influence of environmental factors and are exposed to the body’s immune system by inhalation, and then cause allergic reactions in the body. The most common allergenic fungi, Alternaria, Aspergillus, Penicillium and Cladosporium.

The jobs that expose people to these fungi include agriculture, logging, florist, greenhouse work, sofa repair, etc. Not to mention that a humid environment provides the conditions for the growth of all kinds of fungi and it is better to avoid humid environments as much as possible. .

7 ways to control a runny nose due to allergies

We explained the cause of runny nose. Allergy may remain in people’s bodies for a long time after the end of the autumn season, or even show more severe symptoms. You should pay attention not to underestimate the importance of allergy or sensitivity because over time and not paying attention to its control, it may cause sinus infection and asthma in the body. In the following, we will mention some methods of controlling allergy symptoms.

Allergen identification

Allergen refers to a harmless substance to which the immune system is sensitive. Accurate identification of allergens will help you to better protect yourself against exposure to these factors. Many allergens have been mentioned in the above sections, just be patient and carefully examine your symptoms after being exposed to each one.

To identify the allergen more accurately and easily, you can get more reliable results by going to the doctor and doing a blood test and a skin prick test.

Checking the amount of pollen and spores in the air

It is interesting to know that with a simple search in Accuweather and clicking on the Allergy Outlook section, you can measure the spores and pollen in the air in your area. This tool helps you to measure your allergens in your surroundings and take the necessary measures to prevent the occurrence of allergy symptoms. It is better to know that the amount of pollen reaches its maximum between 5 and 10 am. Therefore, as much as possible, try not to be in the open environment during these hours.

Protective equipment

If you are going to be in an environment full of spores and pollen, use protective cream, hat, glasses, and health mask. Pollens and spores in the space can accumulate on your hair and cause runny nose and allergic symptoms. The N95 respirator mask prevents dust, pollen and spores from entering your respiratory system. It is also better to wash your desired glasses after use so that they are ready for the next use.

Wearing a mask to control allergies


It is better to use filters and ventilation systems at home. Hepa filters separate allergen particles from breathable air and purify 99% of air pollutants. It is also better to separate your outer clothes from the indoor environment of the house. This issue applies not only to clothes outside but also to clothes that are placed in the open environment for a while. It is even better to clean your car and living environment regularly.

Because in addition to spores and pollen, mites, which are allergens, are eliminated by cleaning the environment. Mites are tiny creatures that feed on dead skin cells and thrive in cold, moist environments. Therefore, it is better to mop and sweep your home environment, especially your sleeping environment, at least once a week.

Hot shower

If you can, try to take a warm shower every day before going to bed and wash your hair with the right shampoo. If you plan to use less shampoo and detergent, you can reduce the consumption of these substances and wash your body and hair only with water. Hot water steam can reduce sinus infections, which are the causes of runny nose, and relieve nasal congestion.

Hot water compress

Placing a warm water compress on the forehead and the upper part of the nose several times during the day will remove nasal congestion, reduce runny nose and increase blood circulation in that area. For this, just soak a clean cloth in hot water and place it on your forehead for a quarter of an hour. Repeat this several times to control the allergy.


Phenylephrine nasal spray, antihistamine, pseudoephedrine, oral decongestant, and cetirizine are among the drugs that can be used to stop a runny nose. Sometimes cold and flu medicine can be used to treat runny nose. Before taking, make sure that your medicine does not interfere with other medicines and does not threaten underlying diseases.
