Particulate matter is a type of air pollution comprised of tiny particle of solids or liquid that can cause health problems when inhaled. Some occur naturally from forest fires and dust storms. And of course, human activities contribute also, such as the burning of fossil fuels in cars, power plants and other industrial activities. We usually associate going outside with health, but that is not always the case. A new study from the University of Michigan shows that even short-term exposure to low levels of particulate air pollution may increase the risk of stroke.So what can you do to lower your risk of exposure to particulates? According to experts, the most important thing you can do is avoid exercising outside during high pollution days and near major highways. To find out the particulate and ozone forecast for your area, see the EPA's Airnow site. You can sign up for a daily air quality forecast, delivered to your email.

Some days it might be healthier to walk on a treadmill or otherwise exercise indoors. Sad.
