Causes, Signs and Symptoms of Seasonal Allergies

A seasonal allergy can be defined as an allergic reaction or response to an allergen that is present only for a part of the year. This type of an allergy refers to a pollen allergy caused by the allergens present in trees, weeds and grasses.

Perennial allergies can occur anytime during the year which include allergens like pet dander and dust mite found in most homes. Experts claim that molds can be a seasonal or perennial allergy trigger.

Causes of Seasonal allergies:

Seasonal allergies occur due to the following allergens occurring during a particular time or season of the year:

  • Pollen from trees, grass, plants and weeds is capable of causing spring allergies.
  • Mold can cause allergic reactions in the form of nasal congestion, irritation in the eyes, wheezing, coughing and symptoms that are common in hay fever. Molds can travel indoors through clothes and shoes.

Pollen grains that typically cause seasonal allergies are also otherwise known as hay fever. Pollen allergens travel through wind pollinated trees, grass and weeds. Ragweed is considered to be the most common seasonal allergen that causes serious allergic reactions like asthma and accounts for having affected 75 percent of allergy sufferers at a time during the year. Pollen allergens are not only transported through pollen grains but also through soil and debris.

Molds grow on decaying plants or otherwise are found intact in plants. Molds and mold spores carry allergens which are released through air in dry weather or in moisture-laden rainy seasons as well.

Symptoms of seasonal allergies:

The most common symptoms of seasonal allergies include the following:

  • Sneezing
  • Runny nose
  • Nasal congestion
  • Eyes that turn watery, red and itch very often
  • An itchy throat
  • Dry cough
  • Disturbed sleeping patterns
  • Loss of taste and sense of smell

Seasonal allergies usually show up before the age of twenty though it can also be observed in people in their latter years of life. Researchers claim that the average age for allergies to take place in a human being is actually ten years. However, they can also occur occasionally during their middle or latter years of life.

Experts assert that seasonal allergies or the vulnerability towards any allergy is the result of the occurrence of such an allergy in the family itself. This means that one can be more susceptible to a particular allergy if it runs in his or her family. This is true to the statistics revealed, which support the fact that hay fever is more common among people who have a close relative with a history of such an allergy. Hay fever however is not distinct to a man or woman or a particular community.
