Allergies

An allergy is a normal reaction of the body’s immune system to certain substances. It can either be genetic by nature or environmental. Generally, the human immune systeminitiates it's defense mechanism to protect the body from any harmful bacteria or viruses. At the same time, the immune system similarly reacts when it encounters allergens, which the body interprets as a foreign substance. In normal situations, these reactions are very minimal and kept at a certain level. For some however, specifically those who are genetically allergic to certain substances, these reactions can put their lives at serious risk. Certain types of allergens, such as pollens, dust mites, nickel, latex rubber, heavy scents and leather, can push the human immune systemto release excessive amounts of histamine. This particular chemical is normally produced to protect the body against harmful elements. However,it can also lead to serious allergic reactions for certain people.

Allergic Skin Conditions

Many factors can cause skin irritation. This condition can be due to extreme heat during summers, or it could be caused by certain medications. A fungal or bacterial infection will probably cause another type of skin irritation. However, the most significant factor that causes skin irritation is an immune system disorder. Depending on the level of allergic response in each case, this reaction can likewise lead to serious skin allergy. However, a thin line exists between a simple skin rash and an allergic skin condition.
