Aeroallergens are airborne substances that cause allergic reactions, such as hives or itchy eyes. Pollen and spores are common aeroallergens that can affect people differently based on their sensitivity. Allergic reactions result from hypersensitivity to a harmless substance and can aggravate respiratory conditions. Hay fever is caused by various types of pollen, while spores from mushrooms can cause allergic reactions. Avoiding aeroallergens can be difficult as they are prevalent in nature.
An aeroallergen is an airborne substance that causes some form of allergic reaction such as hives or itchy eyes. There are many different airborne substances that can cause allergic reactions. Pollen and spores are particularly common aeroallergens due to their prevalence in nature. An aeroallergen can affect different people in different ways; a form of pollen that has no effect on one person can cause an extremely unpleasant reaction in another. It all depends on the individual’s level of sensitivity to the specific aeroallergen as allergic reactions result from hypersensitivity to a certain allergen.
An allergy is a specific type of hypersensitivity in which an individual experiences an unpleasant reaction to the presence of a specific substance. Allergic reactions result from a common immune system disorder in which the immune system reacts violently to the presence of a harmless substance. This reaction usually involves inflammation that can lead to itching, sneezing, or a runny nose. It can also aggravate existing respiratory conditions, such as asthma. While many allergens can be avoided, aeroallergens are often very difficult to avoid because many common plants and fungi release pollen and spores that cause allergic reactions in a significant portion of the human population.
Pollens are one of the most significant sources of aeroallergens as they cause seasonal allergies in many people which are often referred to as “hay fever”. The pollens that cause hay fever tend to be present during the haying season, leading to the name “hay fever.” An aeroallergen that causes hay fever can come from many different sources, such as various types of trees, grasses, and weeds. Grass pollen, which is extremely small, is a common aeroallergen that causes allergic reactions in a significant proportion of hay fever sufferers. Hay fever is not caused by any specific type of pollen, so the specific nature of hay fever varies based on the pollens present in a given area and the pollens produced in a given season.
Spores are another common form of aeroallergen causing allergic reactions in a significant portion of the general population. Mushrooms release spores into the air for the purpose of reproduction. These spores tend to travel long distances in the air, giving people ample opportunity to contact and react to them. The role of a spore as an aeroallergen is often particularly significant because fungi possess mechanisms that allow them to forcibly release their spores into the air. Unwanted mushrooms, especially inside, can cause unpleasant allergic reactions.
