Almost everyone suffers a common cold 5-8 times a year. Symptoms of common cold are running nose, feeling of blocked nose, fever, headache, watery eyes, body ache and cough.

Asthma

Asthma is an airway disease. Small bronchi get inflamed and their diameter is reduced in asthma. When this diameter is reduced increased resistance is produced to the moving air in the airways. The mucosa of the small gets inflamed and more secretions are produced in them. Most of the asthma attacks come during the night time. It is experienced as coughing at night.

Hyper reactive airway disease

Hyper reactive airway disease occurs in children less than 5 years of age. Like asthma in adults small bronchi get inflamed and their diameter is reduced. This phenomenon occurs because of environmental stimuli and infections. The cough is typically increased during the night time or in the early morning. Hyperreactive airway disease causes coughing at night.

Allergic pharyngitis

Allergic pharyngitis is another condition that causes coughing at night. It is inflammation of the throat from inside. This inflammation is induced by environmental factors like pollen grains.

Gastroesophageal reflux disease is regurgitation of the food from the stomach to the esophagus up to the mouth. Other symptoms of this disease are better or sour taste in the mouth, chest pain, throat pain and coughing.

Congestive heart failure

Heart is a pump that circulates the blood in our body. For the circulation of the blood the functioning of the heart is an essential thing. If this pump fails it is called heart failure. In congestive heart failure the blood coming from lungs to heart gets accumulated into lungs. This causes coughing which increases when you are lying down. Congestive heart failure can be one of the causes of coughing at night.
