City Tax on Cars Cut Pollution, Kids' Asthma Risk

Posted 19 days ago by Drugs.com

TUESDAY, March 7, 2017 – A tax designed to reduce mid-city traffic in Stockholm, Sweden, was tied to a reduction in asthma attacks in children, a new study suggests. "The key takeaways of this paper are that health gains can be realized through efforts to lower air pollution, and that we need to be patient in waiting for the complete picture to emerge," said study author Emilia Simeonova, an assistant professor at Johns Hopkins University in Baltimore. After Stockholm introduced the "congestion tax" as an experiment in 2006 to discourage people from driving in the center of the city, traffic flow got better and air pollution levels fell by 5 to 10 percent. The tax was made into law in 2007. The tax costs drivers the U.S. equivalent of $2.60 when they drive in certain areas of the city at congested times of the workday. The tax is collected through scanners that gather license plate ... Read more

How to Exercise Safely in Smog

Posted 11 Nov 2016 by Drugs.com

FRIDAY, Nov. 11, 2016 – Scientists say they have figured out the ideal speeds for cyclists and pedestrians to move in order to limit their inhalation of air pollution and still get the full benefits of exercise. "The faster you move, the harder you breathe and the more pollution you could potentially inhale, but you also are exposed to traffic for a shorter period of time. This analysis shows where the sweet spot is," study author Alex Bigazzi, a transportation expert at the University of British Columbia, said in a school news release. The researchers used a computer model of 10,000 people. The investigators found that cyclists should ride between 7.5 to 12.4 miles per hour on city roads. And, pedestrians should walk between 1.2 and 3.7 miles per hour. There are different recommended speeds depending on gender, age and road grades. For example, on flat roads the ideal speeds are: 7.8 ... Read more

Health Tip: Need a Lung Function Test?

Posted 9 Jun 2016 by Drugs.com

-- A lung function test measures how well your lungs are working, helping your doctor diagnose the cause and severity of any problems with your breathing. The U.S. National Heart Lung and Blood Institute says the test is designed to show: The amount of air that you can breathe into your lungs to see if it's in the normal range. The amount of air that you can exhale from your lungs, and how quickly you can do it. The ability of your lungs to bring oxygen to your blood. How strong the muscles that help you breathe are.

Climate Change May Mean More Smoggy Days to Come: Study

Posted 21 Apr 2016 by Drugs.com

THURSDAY, April 21, 2016 – Climate change could cause many major American cities to experience more days with heavy ozone pollution in the coming decades, a new study predicts. If emission rates continue unchecked, regions within the United States could experience between three and nine additional days of unhealthy ozone levels between May and September by 2050, the study authors said. The researchers are concerned that climate change could undo the progress made under the Clean Air Act to rid U.S. skies of air pollution. "We found, in fact, that climate change could be a monkey wrench in our plans," said study co-author Loretta Mickley. She is a senior research fellow at Harvard's School of Engineering and Applied Sciences in Cambridge, Mass. "The number of bad ozone days per summer could double – could increase by as much as a week – by the 2050s," she said. California, the ... Read more

Implanted Lung Valves Show Promise in Some Emphysema Patients

Posted 9 Dec 2015 by Drugs.com

WEDNESDAY, Dec. 9, 2015 – New research suggests that more careful selection of patients could help improve the success rate of valves implanted into the lungs of people with emphysema. The valves aim to improve breathing, allowing patients with the chronic lung disease to be more active and to perhaps survive longer. Previous research into the valves has been mixed, but the new Dutch study found that they work more effectively if physicians are more selective about which patients get them. "The results are relatively impressive," said lung physician Dr. Gary Hunninghake, an assistant professor at Harvard Medical School in Boston. "These are benefits that physicians would want to get, and patients might feel better. This could result in people being more enthusiastic about this technique." However, the valves come with a risk of serious side effects, the study authors noted, and the ... Read more
