Whistling in your nose
If you’d rather not whistle while you work (or breathe), a squeaky nose can be a major annoyance. It is typically a sign of airflow obstruction, which may mean excess mucus is covering the nasal passages. A decongestant (for a cold) or an antihistamine (for allergies) can help clear out the gunk. See a doctor if you experience whistling after nasal trauma. It could be a tear in the cartilage between the nostrils, which is usually repairable.
Wheezing with coughing
Cough, cough, wheeze. If this sounds familiar, you could have asthma. Allergens inflame the airway, squeezing the muscles around it and leaving you short of breath. If you experience coughing and wheezing only at the gym, you may have exercise-induced asthma. See a doctor whenever you experience coughing and wheezing together, or if you have a cough that lasts for more than four weeks or wakes you up at night (which could be signs of untreated asthma or acid reflux).
