Pollen counts hit high levels in the spring and the fall. Knowing when counts are high can be the difference between having a normal day and suffering misery. The explanation for allergies is really pretty simple. Basically, your immune system overreacts to a foreign substance.
Allergic reactions can range from simple discomfort to life-threatening situations.
More than 50 million Americans suffer from allergies. Some of the symptoms include sneezing, wheezing, nasal congestion, coughing, itchy eyes, stomach ache and itchy skin. As many as 40 million people suffer from hay fever. It happens when you breathe particles you are allergic to.
