Common allergies and their symptoms can be broadly categorized into outdoor and indoor allergy triggers. Both outdoor and indoor allergies can make your life really miserable so be aware of the things that could trigger your allergic reactions. For instance, the most common allergies and their symptoms may be caused by different kinds of pollen. Pollen may come from trees, weeds, grasses and shrubs.

Technically, pollen is a harmless powdery substance that is emitted by the male plants into the air to pollinate the female plants. In other words, pollen is necessary to make plants grow and bear fruits. Unfortunately, there are people who are allergic to this stuff. Since it is made up of very tiny particles and can be inhaled by a person, a person who is allergic to this may suffer from different forms of allergies and symptoms.

In most cases, people who are allergic to pollen will suffer from asthma, allergic rhinitis and others. The weather also contributes much to the degree of the sufferings of those people who are allergic to pollen. Humidity, as all experts agree, magnifies the allergic reaction of the individual concerned. Pollen could become trapped in the moisture, therefore staying in the air longer and causing more suffering for those people allergic to it.Common allergies and their symptoms are usually worse in humid conditions which in turn makes it uncomfortable for the sufferer.

Whereas, the outdoor allergens are usually seasonal, indoor allergens on the whole are a nuisance all year round. People who are living in windowless apartments and those who are living in polluted areas are especially prone to common allergies and symptoms. Molds and mites are usually the culprit. Windowless appartments have air that is recycled so the allergens can not escape, which may cause all year round coughing and sneezing.
