An allergy is triggered by what is commonly known as allergen. This process involves a chemical reaction that occurs when one breathes in dust or pollen from the environment. As one walks around especially in a windy day, dust is bound to reach your nose or mouth and pollen that comes from trees is likely to be blown off to the air you are breathing. Many are the times when we don't take caution of the harsh wind blowing dust to our eyes, nose and mouth. It is expected that many will turn to the opposite direction of the wind or they to cover their face to avoid inhaling the dust. Though there are high chances that one will not inhale dust, a good number don't understand that this is not the only time when one can inhale. Pollen grains are almost invisible in the air so this actually means that you can never tell when they get to your nose. Pollen could come from different types of plants like grass, tree or ragweed. In rainy and damp seasons, pollen is usually washed away to the surface or ground.
Disorders like asthma and eczema are highly linked to allergic arthritis. Asthma is more linked with genes and some sort of inheritance from ones extended family. It is an allergy that relates much with dust, especially for a toddler, but it is known to improve with time as the victim grows. All allergies though could be traced down a family's back ground. Experts have been known to say that if parents especially mother are allergic, their children stand a greater chance to be allergic in future too. It is possible to have a family that is all allergic in one way or another. Allergies could really get irritating especially to toddlers who are not in a position to explain how they feel or something related to that.
