Dry Cough: Causes and Simple Home Remedies
Dry cough (definition) is a type of cough that does not produce sputum or phlegm. It can be triggered by infections and cold (the most common causes of dry cough), allergic reactions, traumas, lung cancer, airway obstruction, and other abnormalities. In most cases of chronic dry cough, inflammation is an important feature.
In cases of difficulty breathing, fever, chest pain, heart palpitations, night sweats, or swollen legs or ankles, the situation can be life-threatening and you need to seek immediate medical help. In cases of persistent dry cough, see your health care provider.
Dry cough can be present in people with various respiratory conditions, such as asthma, bronchitis, COPD, cystic fibrosis and many others. In most people, the problem gets worse at night due to additional CO2 losses.
Irritation of urge-to-cough nerve receptors occurs due to low CO2 levels in nerve cells in airways (the same reason as in cases of irritable nerve states in the brain leading to panic attacks, anxiety, and many other problems). Why do people with respiratory conditions often have dry cough? The cause is in low CO2 levels in their airways.

Since these people suffer from chronic overbreathing (even when they do not have dry cough), and they breathe even more during coughing (up to 20 l/min and more), they suffer from reduced-body-O2 content: less than 20 seconds for the body-oxygen test. Note that the medical norm is 40-50 seconds.
The picture below explains the main details of dry cough mechanism and causes of cough. Note that CO2 deficiency leads to spasm of all smooth muscles in the human body. These muscles include bronchi and bronchioles, while their constriction is known as bronchospasm.
An additional cause of persistent dry cough is inflammation that appears and becomes chronic only in cases of positive body voltage due to a lack of electrical grounding. Electrons from Earth quench and prevent development of inflammation.
Two dry cough remedies
dry cough home remedy includes a simple and easy breathing exercise. More than 170 Soviet and Russian medical doctors tested many thoudry cough their patients and discovered that most cases of dry cough could be stopped in 1-2 minutes using "Breathe Easy" exercise (to accumulate slightly more CO2 while being totally relaxed). This breathing exercise calms down nerve cells in airways (the urge-to-cough receptors), and increases body-O2 content.
