      Asthma is where your airway becomes inflamed, so I would guess the inflammation of your airway is only caused by exercise, whereas some people suffer inflammation for other reasons. This is a bit vague, sorry! Maybe ask a medical doctor.

      Asthma is a chronic inflammation of the breathing passages (bronchi) of the lungs. Asthma is characterized by sudden attacks or periods of bothersome or severe symptoms separated by periods of mild symptoms, or no symptoms at all. The inflammatory reaction of asthma is triggered by external factors or specific situations. When a person with asthma is exposed to one of his or her triggers, the inflammation worsens and symptoms begin.

      Exercise can even induce an asthma attack in people who have no other triggers and do not experience asthma under any other circumstances.

      People with exercise-induced asthma are believed to be more sensitive to changes in the temperature and humidity of the air.

      When you are at rest, you breathe through your nose, which serves to warm, humidify, and cleanse the air you inhale to make it more like the air in the lungs.

      When you are exercising, you breathe through your mouth, and the air that hits your lungs is colder and drier. The contrast between the warm air in the lungs and the cold inhaled air or the dry inhaled air and moist air in the lungs, can trigger an attack.

      I’m afraid this is a Q for properly trained medics. I’m only a materials scientist.
