Every year it seems people grumble, “This is the worst allergy season ever.” But the Allergy and Asthma Foundation of America says it’s hard to determine year-to-year the severity of allergy season.
However, there are some explanations for why more Americans are being diagnosed with allergies.Climate change: Priming effect: Hygiene hypothesis:
What are allergies?
Allergies reflect an overreaction of the immune system to substances that cause no reaction in most individuals. In people with allergies, however, these substances can trigger sneezing, wheezing, coughing and itching.
Allergies are not only bothersome, but many have been linked to a variety of common and serious chronic respiratory illnesses, such as sinusitis and asthma. Factors such as your family history with allergies, the types and frequency of symptoms, seasonality, duration and even location of symptoms (indoors or outdoors, for example) are all taken into consideration when a doctor diagnoses allergies.
With proper management and patient education, allergic diseases can be controlled, and people with allergies can lead normal and productive lives.
