Seasonal Allergies

Each year, millions of Americans suffer from seasonal allergies. However, a certain percentage of those who suffer from seasonal allergies dismissed as chronic cold. To better understand this, we need to define and differentiate the common cold.


Unlike colds, which usually occur during the winter or when there is a sudden change in temperature, allergies are caused by allergens. This causes an allergic reaction on the function of the body of a man sensitive to the particular allergen that is not experienced by the average person.


Allergic rhinitis can be classified as perennial and perennial seasonal allergies. Occur at any time of year as long as the individual is exposed to the allergen such as dust mites and domestic animal dander. Seasonal allergies, on the other hand occur at the same time each year or during certain seasons, hence the term. They are caused by pollens of flowering plants that are transported in the air during the process of pollination.


When someone has a cold, he began to sneeze, then later begins to have a runny nose and congested. Sneezing is less frequent after the initial phase. If one has allergies, symptoms occur at the same time. Sneezing is often associated with runny nose and watery eyes. Itching in the nose and eyes are particularly troublesome in allergies. In many cases, however, this develops in allergic rhinitis and asthma. And unlike cold, which usually last from 7 to 10 days, allergies to continue until the person is no longer exposed to the allergen.


ragweed allergy, also known as autumn allergies or hay fever, is the most common allergy season. This occurs from mid-August until October. About 75% of people develop allergies become allergic to pollen from ragweed. Ragweed grows in vacant lots and roadsides. Studies have also indicated that most people allergic to ragweed also develop allergic reactions to pollen others. It is therefore not surprising that the onset of allergic symptoms during spring and summer when pollen grains of flowering trees and grasses are present in the air.


The nasal discharge of people who have colds usually yellow which means it is caused by an infection. Sometimes colds are also accompanied by fever. Those who suffer from seasonal allergies generally have no fever, and as it is not caused by a bacterial or viral infection, runny nose is clear and watery.


Whether the disease is caused by a cold or an allergy is sesonal, it must still pay a toll on health. In both cases there is a loss of appetite and sleep problems also occur that disrupts how a person performs his normal activities. Prevention is always the cure. Appropriate information also helps in the diagnosis of disease while the appropriate medication can be taken.
