Seasonal allergies are caused by allergens that you are only exposed to at certain times in the year. You are exposed to excess sunlight during summers. Allergy to pollen grains is very common during the spring season because, during this season, many flowers bloom and pollen grains are dispersed. Pollen allergies are also known as hay fever. Whereas allergy to dust and insect bite are perennial allergies because these are not linked to any particular season and can occur at any time of the year.
