But when you have an asthma attack, less air can get in and out of the lungs. You'll cough and wheeze. Your chest feels tight. The airways get squeezed. The airways make mucus.
Some asthma attacks are mild.
Some asthma attacks can get very serious. People with asthma may wake up at night because of coughing or trouble breathing. Although asthma has no cure, people with asthma can have normal, active lives when they learn to control their asthma. They can sleep well at night. They can work, play and go to school.
