Asthma is a chronic condition, meaning that it occurs on a long-term basis, which is characterized by the inflammation of your airways. Asthma attacks are fits of wheezing and tightness in the chest that make it extremely difficult to breathe. These attacks tend to occur at night or in the early morning, but can also be triggered by doing exercise.
Coughing is one of the primary symptoms of asthma and it tends to occur at night. This annoying symptom affects more than 25 million people across the United States, and it occurs as a result of mucus in your airways becoming sticky and thick, getting trapped in airways that become tighter and tighter.
After a long day of work, this mucus gathers up and at night time, when you lie down, it may begin moving across your trachea. At this point, your body responds by trying to get it out of your system, causing painful coughing fits.
