What should you know about an itchy throat after exercise?

Faster breathing dries the mouth and throat, especially during outdoor activity, cold weather or sessions in air-conditioned spaces. Nasal allergy may add mucus, sneezing or post-nasal drainage. Some people develop exercise-related narrowing of the airways, which may cause cough, chest tightness, noisy breathing or reduced stamina as well as throat discomfort. A common cold can make the airways more sensitive while you recover. The trigger may be the environment, intensity, an irritant or a health condition rather than exercise itself.

Slow down or stop if symptoms are building, move away from smoke or strong scents, and sip water once breathing is comfortable. A gradual warm-up and breathing through the nose when possible may reduce dryness. Note the activity, setting, weather, intensity, foods, medicines and whether cough or wheeze followed. Do not borrow another person’s inhaler or begin Allergy Medication without professional advice. A clinician can decide whether you need an airway assessment or an individual exercise plan.

Arrange a review if throat itching recurs, limits activity, or appears with cough, wheeze, chest tightness or prolonged breathlessness. Stop exercising and seek emergency help for severe breathing difficulty, blue lips, faintness, rapidly worsening symptoms, or swelling of the throat, tongue or lips. Do not resume the session while those symptoms are present.

Could this be airway narrowing, nasal allergy or simple dryness? Should I have breathing tests? How can I exercise safely while the cause is being assessed?
