postnasal drip
nasal gland constant secretion of mucus Helps clear nasal passages and remove dust and other particles. This mucus can get down your throat and be swallowed without you realizing it, but when you produce more mucus than normal, postnasal drip can be very annoying, especially at night, and cause nocturnal cough.
“During the day, when you stand upright, these fluids drain naturally with the help of gravity, you swallow them and flush them out. When you lie down, you lose the help of gravity Mucus collects in the back of the throat. If mucus reaches the vocal cords of the throat, or if some mucus is inhaled and enters the lungs, a wet cough can cause phlegm or mucus. “’, otolaryngologist Neil Bhattacharyya explained on Harvard Portal.
gastroesophageal reflux
When the stomach contracts, stomach acid moves into the intestine, but in people with reflux, stomach contents back up into the esophagus because the valve between the stomach and esophagus (the lower esophageal sphincter) doesn’t close properly.this leads to aciditya burning sensation behind the breastbone when gastric juices irritate the esophagus and throat.

heart failure
In heart failure, the heart cannot effectively pump blood throughout the body. This causes fluid to build up and leak into other tissues. “During the day, the fluid flows down the legs by gravity, but when you lie down enters the lungs and causes a cough“” said the expert.
Unexplained nighttime coughing may be the first sign of heart failure.
