these cough remedies require nothing at all: you just need to learn how to breathe correctly, or how to breathe closer to the medical norm. what happens during coughing is we loose too much co2 and carbon dioxide is very important for healing of our airways, for normal work of our urge-to-cough receptors, because when we hyperventilate, and this is exactly the case, according to many medical studies,
for people with copd, asthma, cystic fibrosis and other conditions, these people have reduced amount of co2 in their airways and that causes irritation of their urge-to-cough receptors. and therefore, they have chronic problems with coughing. apart from that, heavy breathing (or hyperventilation) reduces oxygen level in body cells. and that causes suppression of the immune system, because when we develop cell hypoxia or tissue hypoxia, we start to generate free radicals in cells, due to anaerobic
respiration of our cells. so, oxygen is very fundamental for our health, and hyperventilation causes exactly the opposite effect. let us look at this research abstract written by doctors in relation to coughing. therefore, people with chronic coughing are going to benefit from very simple breathing exercises which are going to be explained next. the very first step is to learn how to cough only through your nose. so, you keep your mouth close and start coughing only through the nose. the next step is to learn how to cough with your mouth and with your nose closed. that means
you close your nose and try coughing this way. this way you are going to have about normal concentration of co2 in your airways, and that is going to calm down your urge-to-cough receptors. in addition, there is a third exercise which is called reduced breathing exercise, and this reduced breathing exercise will teach you how to breathe a little bit less air, so that you have more carbon dioxide, more co2, which improves oxygen transport.
and eventually, when you achieve about 30 seconds for the body oxygen test, you are going to eliminate inflammation, in a significant degree, and your bouts of coughing will disappear completely.
