Causes of coughing at night

There are many factors that lead to coughing while sleeping at night. It may be due to certain chronic diseases, or a mild cough caused by normal lung regulation, or it may be caused by indigestion due to eating too much before going to bed, etc.

Between 1 and 3 a.m., the body's blood and qi flow to the lung meridian. At this time, the lungs begin to detoxify, regulate and repair themselves. A slight cough at this time is a normal phenomenon. However, if you smoke, your cough will be more severe at night.

2. Physical illness

If the patient has chronic left heart failure, the cough may be caused by aggravated lung congestion when sleeping in a supine position at night.

In addition, if you suffer from chronic bronchitis or other diseases, you may cough violently because of the increased sputum stimulation when you lie down at night;

It may also be due to chronic pharyngitis, mouth breathing while sleeping, long-term stimulation of the throat and respiratory mucosa by cold air, causing airway spasm and coughing, etc.

3. Viral infection

If you have a cold or inflammation that causes viruses to invade and irritate your respiratory tract, it may also cause coughing at night. Among them, the most common one is mycoplasma infection. The cough caused by mycoplasma infection is more severe at night and may be accompanied by a small amount of sputum.

4. Improper diet

If you consume spicy and irritating food for a long time, it is easy to cause excessive lung fire and trigger cough. Especially eating too much before going to bed at night may cause the stomach and intestines to not get proper rest and cause food accumulation cough. If the cough at night is caused by indigestion, you can feel phlegm in the throat.
