For people with allergies and asthma, sometimes the very air they breathe can be bad for their health. That’s because a variety of pollutants in our air -- collectively called smog -- can aggravate asthma and allergy symptoms, leaving people with these conditions struggling to breathe.
The biggest spring allergy trigger is pollen. Trees, grasses, and weeds release these tiny grains into the air to fertilize other plants. When they get into the nose of someone who’s allergic, they send the body's defenses haywire.
The immune system mistakenly sees the pollen as a danger and releases antibodies that attack the allergens. That leads to the release of chemicals called histamines into the blood. Histamines trigger the runny nose, itchy eyes, and other symptoms that are all too familiar if you have allergies.
Pollen can travel for miles, so it’s not just about the plants in your neighborhood.
Grasses and weeds:
Pollen counts tend to be particularly high on breezy days when the wind picks up these sneeze-inducing grains and carries them through the air. Rainy days, on the other hand, wash away the allergens.
Start with your regular doctor. She may refer you to an allergist for tests.
The allergy specialist may give you a skin test, which involves either a pricking the surface of the skin with a tiny amount of allergen (prick test), or injecting a tiny sample of a diluted allergen under the skin of your arm or back. If you’re allergic to the substance, a small red bump (called a wheal or hive) will form. Sometimes, you may get a blood test.
