Dry Cough: Causes and Remedies That Work in 1 Min Fast
A dry cough (definition) is a type of a cough that does not produce sputum or phlegm. It can be triggered by infections and cold (the most common causes of a dry cough), allergic reactions, traumas, lung cancer, airway obstruction, and other abnormalities. In most cases of the chronic dry cough, an 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 a persistent dry cough, see your healthcare 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.
There is an irritation of the urge-to-cough nerve receptors which occurs due to low CO2 levels in nerve cells in the airways. It is the same situation as in cases of inflamed nerves in the brain leading to panic attacks, anxiety, and many other problems. Why do people with respiratory conditions often have a dry cough? The cause is low CO2 levels in their airways.

These people suffer from chronic overbreathing, even when they do not have a dry cough. They also will breathe more during coughing up to 20 l/min and higher. They suffer from reduced body-O2 content or 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 a cough. Note that CO2 deficiency leads to spasms 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.
Dry cough remedies
The main dry cough home remedy includes a simple and easy breathing exercise (see the video below). More than 170 Soviet and Russian medical doctors tested thousands of their patients and discovered that most cases of a 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-oxygen content naturally and fast. Here is our video with detailed instructions that explain how to get rid of a dry cough fast.
The permanent remedy or a dry cough cure
When people with a dry cough achieve a certain result, in seconds, for their body-oxygen test, they become free from airway dryness and have no more problems with this symptom. This number is provided right below here as your bonus content.
