A brief radio clip on some new Asthma diagnostics, which could prove very valuable.

Professor Cecilie Svanes of University of Bergen, Norway has published research, which was presented to the European Respiratory Society in Munich.

It shows that men who smoke in their teens stand a more than 50% chance of having children with non-allergic Asthma (that excluding Hay ever).  If they smoked before age 15, this could be as high as 60%.  This is only reduced if the men give up more than 5 years before conceiving.

The study covered 13000 men and women in total and the women’s habits were not implicated.

I believe this result was not expected.

For most of us, what we have come to know as breathing is in fact over-breathing.  Taking in and breathing out a higher volume of air than our body needs.  So why should this be a problem you may ask. Isn’t lots of deep breathing healthy? It’s a fair question, based on what we think about oxygen and carbon dioxide.

Up to this year, I was firmly in the, oxygen good/carbon dioxide bad camp with most others.  Only now do I understand how valuable and scarce carbon dioxide is for our bodies.  This is not to be confused with the CO2 emissions in the environmental news.   The way our bodies work, we have to make the CO2 we need and hold on to it for internal uses, but with all this deep breathing and over breathing, we lose what we need and this creates symptoms such as wheezing, coughing, snoring, sleep disruption,  poor digestion and many, many others.
