Sometimes medical research is breathtaking. Take this study looking into the “impact of airflow obstruction on long-term mortality in patients with asthma in Japan, published in Allergology International.
The aim of this “retrospective 26-year study was to investigate the long-term mortality risk of airflow obstruction in asthmatics”.
The shock-horror conclusion is that “individuals with airflow obstruction showed significantly higher long-term respiratory-related and allcause mortality than those without airflow obstruction. Current smoking appeared to be associated with airflow obstruction and poor prognosis. Respiratory-related conditions, especially asthma attacks, were the main causes of mortality among victims with airflow obstruction.”
In other words, if you find breathing difficult then you are more likely to die from respiratory problems.
