From Science Daily:

Overweight or obese people breathe more air pollutants

Overweight or obese adults can breathe 7-50% more air per day than an adult with healthy weight does, which makes them more vulnerable to air contaminants causing asthma and other pulmonary diseases, according to a study by Dr. Pierre Brochu, a professor at Université de Montréal's School of Public Health. For overweight or obese children, daily inhalation rates are 10-24% higher than for normal weight children.

Study based on more than 1,900 participants: Brochu's study is based on an analysis of data from 1,069 participants aged 5-96 years, compared with data collected from 902 normal weight people (in a study conducted by Dr. Brochu in 2011). Data were analyzed, among other things, according to participant age and gender. Adults were also classified according to their body mass index

The situation for obese children may be even more worrisome, according to the data analyzed by Dr. Brochu. In fact, because of their much higher metabolism -- in relation to their low body weight -- they breathe more air per kilogram of weight than obese adults do to maintain their basic functions and perform their daily activities. The same trend applies to men compared to women. "It remains to be seen if high inhalation rates are a factor in the development of asthma and other lung diseases in adults and children," said Dr. Brochu, who hopes to eventually validate this hypothesis.

 It seems like every day numerous new science and health articles are published. I have always enjoyed going to various sites and looking for articles that I actually think are significant and could help us understand the world around us, or what we should be concerned with, or even how to live a good and healthy life. For years I have been sending out articles to friends and family and finally decided to, what the heck, send them out to everybody else by posting them on a web-site.

I have always been interested in the interplay between our environment and health. There is still so very much that is unknown. And then there are new exciting areas of research using new technologies that make us rethink what we thought we knew, and how to treat diseases and live a healthy life.

I've decided to start by posting some articles that were published earlier this year because they lay out the groundwork for a lot of new exciting research. Stuff that we didn't know about or understand back when learning basic biology in school.
