Cough Causes and Types
A cough is an ejaculation of air from the human lungs which can be heard. It is actually used to protect the respiratory system by clearing it of foreign particles. So it is obvious that coughing is good, but not always. If it becomes persistent, it will be problem for anybody.
Naturally cough is nothing but reflexes by human body, to throw any unwanted particles found at in respiratory system, out of body. The reflex is activated in the cough centre of the brain. So if the respiratory system is not infected by bacteria or microbe, coughing is good for human body. Also it is found that naturally each human coughs 2-3 times an hour. It becomes very painful when a person develops persistent dry cough.
Types of Cough:
Cough is of two types,
1) Dry cough: When cough is dry, means if cough doesn’t include any fluid in it, it is called as dry cough. It will swallow the respiratory system, and hence becomes irritating.
2) Productive cough: When cough includes fluid (septum) in it, it is called as productive cough. Productive cough shows many colours which varies up on the infection; it can be gray, green, and red. If the blood gets included in septum, it becomes red, which is a serious sign. If you are have a productive red cough, consult a doctor as soon as possible.
