Seasonal Allergies usually occur during spring, fall and summer. Winter is not a common time for Allergies because there are not as many plants in bloom during this time due to the cold weather. When plants bloom and flourish, so do seasonal Allergies but this does not mean that this allergy is caused mainly by plants. The weather can also play a big role in triggering seasonal allergies.
Seasonal Allergies Due To Pollen And Dust
Pollen is one of the main causes of seasonal Allergies as well as dust and mold spores. These are common occurrences during spring and summer as well as during fall. The pollen from plants can cause serious hay fever in some individuals who are highly sensitive to the allergens they contain. Pollen tends to become airborne when the right season comes and these cause allergic reactions in individuals.
There is actually little that you can do about being allergic to pollen, dust and mold spores. Seasonal Allergies are usually controlled and not eliminated with the use of antihistamines. Although, not all areas of the city may have pollen, mold spores or dust, chances are, whenever you go around the city, you will encounter airborne mold spores, pollen and dust separately. If you are sensitive to any of these allergens, then you are highly likely to have an allergic reaction.
What To Expect From Seasonal Allergies
Seasonal Allergies usually manifest themselves as sneezing, runny noses, itchy eyes and other allergic rhinitis symptoms. You might initially think that you have a cold but actually there is a great deal of difference between the two. Seasonal Allergies are usually not accompanied by fever whereas a cold is and a cold usually lasts for around 10 days compared to seasonal Allergies that last for as long as you are exposed to the allergens.
Seasonal Allergies also react well to antihistamines whereas colds to decongestants. Allergies that rely on seasons also occur during summer, spring and fall compared to a cold that usually occur during winter. Allergies are also dependent on the individual’s reaction to allergens while colds can be transmitted from one person to another.
As stated earlier, these kinds of Allergies react well to antihistamines. Some may need stronger medication to control but the key is to lessen your exposure to the allergens. Allergens updates are also posted by the government to help out those who are sensitive to hay fever and other allergens.
Allergic Colds
Allergic rhinitis
Also known as hay fever , this condition refers to an allergy to pollen , dust , pets etc. which results in sneezing / running nose , nasal stuffiness , watery and itchy eyes.
In most cases, symptoms are mild and at the most are inconvenient . But if its severe and persists for extended periods of time , it is a cause of concern and needs to be treated.
If the allergy is due to pollen , symptoms are seen in particular seasons depending on when the plant in question flowers. Allergies to other things could be throughout the year.
Diagnosis is by clinical symptoms. Skin/ blood allergen testing can also be done to pinpoint the cause for the allergy.
Though the obvious preventive step is to avoid exposure to the offending agent , in most cases since its environmental, it just cannot be avoided. Regular cleaning of living spaces and personal effects minimizes exposure to allergens.
Medicines for treatment fall into the following categories :
Antihistamines – these control symptoms such as sneezing , watering and itchiness of eyes etc. Though the older ones are cause drowsiness , the newer generation antihistamines have minimal sedative effects and are safe. There are even antihistamine nasal sprays which take effect fairly quickly.
Decongestants – are often combined with antihistamines in tablet form or are available as nasal sprays. Though these provide instant relief from nasal stuffiness, it is wise not to use them for more than a couple of days since long term administration is known to cause adverse changes in the nasal skin lining. This is also due to preservatives added to the solution. Also, with repeated use , the response decreases till there is no effect ultimately.
Intra nasal steroids are very effective in the treatment of symptoms that are present for long periods.. It is administered locally and hence is safe for long term use.
Other drugs that influence the allergic reaction cascade such as cromolyn and leukotriene receptor antagonists are also useful but need to be taken on a regular basis.
Oral/ injectable steroids are rarely given keeping in mind their long term effects and are only prescribed for short periods when symptoms are very severe.
Immunotherapy is also an option for those whose symptoms are severe, uncontrolled by medication , or if other allergic conditions (eg. asthma, eczema ) begin to develop.
