    New Link Between Pollution, Temperature and Sleep-Disordered Breathing

    ScienceDaily (June 14, 2010) — Researchers from Brigham and Women's Hospital and the Harvard School of Public Health have established the first link between air pollution and sleep-disordered breathing (SDB), a known cause of cardiovascular diseases.

    Antonella Zanobetti, Ph.D., Susan Redline, MD, MPH, Diane Gold, M.D., M.P.H. and colleagues explored the link between air pollution levels, temperature increases and sleep-disordered breathing using data from the Sleep Heart Health Study, which included more than 6,000 participants between 1995 and 1998, and EPA air pollution monitoring data from Framingham (Massachusetts), Minneapolis, New York City, Phoenix, Pittsburgh, Sacramento, and Tucson.

    SDB affects up to 17 percent of U.S. adults, many of whom are not aware that they have a problem. Air pollution is also an endemic issue in many of the nation's urban areas. Both SDB and pollution have been associated with a range of health problems, including increased cardiovascular mortality. "The influence of air pollution on SDB is poorly understood," said Dr. Zanobetti. "Our hypothesis was that elevation in ambient air pollution would be associated with an increased risk of SDB and nocturnal hypoxia, as well as with reduced sleep quality." The researchers further hypothesized that seasonal variations in temperature would exert an independent effect on SDB and sleep efficiency.

    "Particles may influence sleep through effects on the central nervous system, as well as the upper airways," wrote Dr. Zanobetti. "…Poor sleep [associated with poor health outcomes] may disproportionately afflict poor urban populations. Our findings suggest that one mechanism for poor sleep and sleep health disparities may relate to environmental pollution levels."

      I live in the Ohio River Valley, home to dirty coal fired power plants, high air pollution and ozone warnings.  It affects people's health- asthma is at high levels as well as a variety of other ills.

      Obama's EPA is tightening up SO2 level for the first time in 40 years.  This will cut deaths by 3-5000.

      Fine particle pollution from U.S. power plants cuts short the lives of nearly 24,000 people each year, including 2800 from lung cancer.

      The average number of life-years lost by individuals dying prematurely from exposure to particulate matter is 14 years.

      Hundreds of thousands of Americans suffer each year from asthma attacks, cardiac problems, and respiratory problems associated with fine particles from power plants. These illnesses result in tens of thousands of emergency room visits, hospitalizations, and lost work days each year.

      Power plant pollution is responsible for 38,200 non-fatal heart attacks per year.

      The elderly, children, and those with respiratory disease are most severely affected by fine particle pollution from power plants.

      People who live in metropolitan areas near coal-fired plants feel their impacts most acutely . their attributable death rates are much higher than areas with few or no coal-fired plants.

      The vast majority (at least 90 percent or 22,000) of the deaths due to fine particle pollution could be avoided by capping power plant sulfur dioxide and nitrogen oxide pollution at levels consistent with the installation of today's best available emissions controls.

      Particles should be a big concern for their affect the heart and now sleep.

      CO2 standards from coalfired plants were also enforced in 2009.

      All this makes coal cleaner AND more expensive, reducing its consumption eventually.

      I know we should do more about oil, but coal sucks too.  the little songbirds can't enjoy landing on water like this....

      coal sludge

      and over this sort of landscape.


      But the marshes of Louisiana are a more critical habitat than the mountains of West Virginia because they are the location where many bird species overwinter or pause on longer migrations.  The oil is a real problem that will have far reaching impacts.
