What I mean is that in the majority of people with allergies exercise helps open the nasal passages. It does this by two main mechanisms: neurologic and chemical. In most persons, exercise increases preferentially the <em>sympathetic<\/em> nerves that control blood vessel size, constricting these blood vessels, and thus, improving nasal patency (being open or expanded).<\/p>\n<p>Exercise also releases \u201cadrenal-like\u201d chemicals that exert the same effect on the nasal blood vessels.<\/p>\n<p>In a small number of people, exercise preferentially stimulates the <em>parasympathetic <\/em>nerves, which dilate nasal blood vessels and cause congestion. This phenomenon is called exercise-induced rhinitis. It is similar to a related phenomenon in asthmatics called exercise-induced-bronchospasm.<\/p>\n<p>One predisposing factor to exercise-induced-rhinitis is deviation of the nasal septum. Apparently, people with septal deviation have a chronic disparity in air flow through the two nostrils. For some reason, this makes the parasympathetic nerves more sensitive, and thus their adverse response to exercise.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dear Dr. K: Dear Dr. K.: My husband and I both have allergies and we are both triathletes.
