Whаt is the mаin purpоse оf the sectiоn Allergies 101? Allergy 1012 An аllergy is a reaction of your immune system to something that, for most people, is essentially harmless, such as pet dander, nuts, or pollen. For most seasonal allergy sufferers, the diagnosis is hay fever, or—as your doctor would write it down in your medical chart—allergic rhinitis. Reactions range from annoying—sneezing, itching, watery eyes, stuffy nose—to dangerous: in some people, allergies can trigger asthma attacks.3 Seasonal allergies afflict up to 30 percent of the world’s human population, studies have found, and the Cleveland Clinic reports a rising allergy prevalence. For most people, allergies aren’t life threatening, but they can hamper one’s enjoyment of life—for months at a stretch. Tree pollen strikes in the spring, grass pollen in the summer, and weed pollen in the summer and fall.4 If you have hay fever, your worst enemy is probably ragweed—common ragweed, giant ragweed, lance leaf ragweed, or western ragweed. Ragweed likely causes more hay fever than all other plants put together, according to USDA plant physiologist Lewis Ziska, and a single ragweed plant can produce a billion pollen grains. Those grains contain a protein that excels in annoying the human immune system.
