Allergies to Your Environment

Dealing with allergies to your environment?

Sneezing, itchy eyes, runny and itchy nose, congestion, scratchy throat are no fun and can be more than just annoying. These are what we call “allergies”. It’s also sometimes called hay fever, even though it involves neither hay nor a fever.

Allergy medicines, DrEpperly.comAllergies to your environment can ruin your quality of life and decrease your productivity. Because of that, millions of dollars are spent on drugs called antihistamines like Allegra, Claritin, or Zyrtec. (When there is a –D after these names, it means they also have a decongestant in them like pseudoephedrine).

These medicines block the effects of the chemical histamine which is released by cells called mast cells. These mast cells do this in response to exposure to various biological molecules in the air called antigens or allergens.

When antigens attach to receptor sites on the mast cells of sensitive individuals, histamine and other chemicals are released. Histamine causes itching, swelling of mucous membranes, and increased production of mucous.

The amount of reaction of a person with allergies to their environment to these allergens depends on genetics, degree of exposure, and how much other stuff the person is being subjected to, also called “total load”.  One of the keys to treating allergies is avoidance: keeping windows closed, turning on the air conditioning, using air filters (which help to a limited degree), or in extreme cases moving to another part of the country.
