Asthma Symptoms

How Asthma Affects Breathing

Symptoms of asthma may include:

  • Chest tightness
  • Coughing, especially at night or early morning
  • Shortness of breath
  • Wheezing, which is a whistling sound when you breathe out

Other conditions can cause these symptoms. But in asthma, the symptoms often follow a pattern:

  • They come and go over time or within the same day.
  • They start or get worse with viral infections, such as a cold.
  • They are triggered by exercise, allergies, cold air, or breathing too fast from laughing or crying.
  • They are worse at night or in the morning.
