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

As Traffic Piles Up, So Does Air Pollution

Posted 12 Sep 2016 by Drugs.com

MONDAY, Sept. 12, 2016 – Stuck in traffic? Shut your car windows and turn your ventilation system to re-circulate air, researchers advise. Doing so can reduce your exposure to toxic air pollution from a traffic jam by up to 76 percent, a new study suggests. "Where possible and with weather conditions allowing, it is one of the best ways to limit your exposure by keeping windows shut, fans turned off and to try and increase the distance between you and the car in front while in traffic jams or stationary at traffic lights," said study senior author Prashant Kumar. "If the fan or heater needs to be on, the best setting would be to have the air re-circulating within the car without drawing in air from outdoors," Kumar, who's with the University of Surrey in England, said in a university news release. The investigators also found that pedestrians are exposed to high levels of vehicle air ... Read more

Doctors' Decision-Making Tool Could Cut Unnecessary Antibiotic Use

Posted 2 Sep 2016 by Drugs.com

FRIDAY, Sept. 2, 2016 – A new decision-making tool for doctors may help reduce unnecessary use of antibiotics in children with respiratory tract infections and cough, researchers report. Respiratory tract infections with cough are the most common reason children are prescribed antibiotics. But as many as one-third of those prescriptions may be unnecessary, the study authors said. Using information from more than 8,000 children, the investigators identified seven key predictors that could be used to help determine whether a child with a respiratory tract infection and cough is likely to require antibiotics. Those predictors are: short illness (less than three days); fever of 100 F or higher; younger than 2 years old; respiratory distress; wheeze; asthma; and moderate/severe vomiting in the previous 24 hours. Children with none, or just one, of these predictors are at very low risk of ... Read more

Clean Pools Can Still Pose Health Hazards

Posted 2 Jun 2016 by Drugs.com

THURSDAY, June 2, 2016 – Nothing seems better on a hot day than hopping into a cool swimming pool. But, new research might prompt you to shower first and make sure your kids don't pee in the water. Researchers from the University of South Carolina report that the disinfectants used to keep pools clean can create dangerous disinfection byproducts (DBPs) when combined with sweat, personal care products and urine. Some of these byproducts have caused genetic damage to cells in laboratory tests, while other reports have found higher rates of bladder cancer and respiratory issues in people who are around pools regularly, the researchers said. And though the study findings held true for public pools, private pools and hot tubs, the researchers flagged indoor pools and hot tubs as a top concern, too. "I never had my kids on a swim team in an indoor pool, swimming every day. I would make that ... Read more

Health Tip: Breathe Healthier Air at Home

Posted 27 May 2016 by Drugs.com

-- To help prevent breathing problems, keep the air inside your home clean. The American Lung Association recommends: Allowing no one to smoke inside your home. Performing a radon test to check for the invisible gas, which has been linked to lung cancer. Running a dehumidifier or air conditioner to keep humidity levels below 50 percent. Keep the filters inside those appliances clean. Repairing any leaking water pipes immediately. Keeping pests away by cleaning up food spills and storing food properly. Never using an outdoor wood burning stove inside the home. Finding the source of odors and cleaning them, rather than masking the smell with candles and room sprays. Opting for less toxic household cleaning supplies. Read more

4 Ways You Can Cut Smog in Your Town

Posted 4 May 2016 by Drugs.com

WEDNESDAY, May 4, 2016 – Those hazy days of summer may mean high smog levels for some northeastern U.S. states, but you can help reduce air pollution where you live, the U.S. Environmental Protection Agency says. Smog is a combination of ground-level ozone and fine particle air pollution. "Air pollution is a significant public health issue in New England," said Curt Spalding, regional administrator of the EPA's New England office. "New Englanders need to pay close attention to air-quality alerts and limit strenuous outdoor activity on air-quality alert days. In addition, we can all take individual actions to reduce the air pollution that contributes to this public health risk," he said in an agency news release. As part of Air Quality Awareness Week May 2-6, the EPA outlined four steps you can take to reduce air pollution, including: Use public transit or walk whenever possible. Set ... Read more

Smog May Boost Risk for Several Cancers

Posted 29 Apr 2016 by Drugs.com

FRIDAY, April 29, 2016 – Long-term exposure to fine particles of air pollution – from cars, trucks, power plants and manufacturing facilities – is tied to an increased risk of dying from several kinds of cancer, a new study suggests. "Air pollution remains a clear, modifiable public health concern," said researcher G. Neil Thomas, a reader in epidemiology at the University of Birmingham in England. "Put simply, the more of these particulates there are in the air, the greater the risk of getting these cancers," Thomas said, although the study did not prove the particles actually cause cancer. The study, involving more than 66,000 older residents of Hong Kong, found an increased risk of dying from cancer for even small increases in exposure to these tiny particles of air pollution, which are measured in micrograms per cubic meter (mcg/m3). For example, the overall risk of dying from ... Read more

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

Doctors Issue Call to Combat Climate Change

Posted 18 Apr 2016 by Drugs.com

MONDAY, April 18, 2016 – Climate change is already harming people's health by promoting illnesses linked to warmer temperatures and changing weather patterns, a leading group of U.S. doctors says in a new position paper. As a result, the American College of Physicians (ACP) is calling for "aggressive, concerted" action to fight climate change by curbing man-made greenhouse gas emissions. Respiratory illnesses, heat stroke and infectious diseases like Zika virus, dengue fever and cholera are flourishing as global temperatures rise, said Dr. Wayne Riley, president of the college. "Our climate is already changing and people are already being harmed. If we don't begin to address climate change, we're going to see more and more manifestations of these health problems," Riley said. "There is clear, compelling scientific consensus that climate change is real," he added. "There is no dispute." ... Read more

Cleaner Air in California May Mean Healthier Kids: Study

Posted 12 Apr 2016 by Drugs.com

TUESDAY, April 12, 2016 – Southern California has cleaner air than it did 20 years ago, and children there may be breathing better because of it, a new study suggests. Researchers found that as the smog over eight Los Angeles-area communities lessened, children became less likely to suffer from bronchitis, congestion and chronic coughs. The findings, published April 12 in the Journal of the American Medical Association, do not prove that improvements in air quality deserve the credit. "We're careful to say this is an association. We can't say it's cause-and-effect for certain," said lead researcher Kiros Berhane. He is a professor of preventive medicine at the University of Southern California's Keck School of Medicine, in Los Angeles. Still, Berhane said, the findings have "a lot of credibility," partly because the study followed children living in the same handful of communities from ... Read more

Smog's Health Effects Persist for Decades, Study Finds

Posted 10 Feb 2016 by Drugs.com

TUESDAY, Feb. 9, 2016 – Air pollution can increase the risk of premature death, even decades later, one of the longest running air pollution studies suggests. British scientists found the negative health effects of air pollution – such as a higher risk of lung and heart disease – can persist for more than 30 years. The study authors suggested that more research into the long-term health effects of air pollution – often called smog – is needed. "Air pollution has well established impacts on health, especially on heart and lung disease," study author Dr. Anna Hansell, from Imperial College London, said in a university news release. "The novel aspects of our study are the very long follow-up time and the very detailed assessment of air pollution exposure, using air-quality measurements going back to the 1970s." The researchers monitored air pollution levels in areas of England and ... Read more

Health Tip: Considering a Humidifier?

Posted 21 Jan 2016 by Drugs.com

-- Dry, cold winter air may lead you to consider running a humidifier. But if you have allergies, the device may not be the best choice. The American Academy of Allergy Asthma and Immunology offers this advice: Running a humidifier may promote mold and dust growth. Dust mites, a common cause of allergies, thrive in humid environments. Maintain a humidity level of between 30 percent and 40 percent to reduce dust mites. Regularly change and clean the filter in your humidifier to prevent mold growth. Also regularly clean the humidifier itself. Use demineralized or distilled water in your humidifier, which will help lessen bacteria and dust. Read more

Agricultural Pesticides May Affect Kids' Breathing

Posted 3 Dec 2015 by Drugs.com

THURSDAY, Dec. 3, 2015 – Early exposure to widely used pesticides may harm children's lungs, a new study says. Previous research has looked at the harmful effect of organophosphate pesticides – chemicals that target the nervous system – on adult agricultural workers. This new study looked at children living in an agricultural area where the organophosphates are used. "This is the first evidence suggesting that children exposed to organophosphates have poorer lung function," said study senior author Brenda Eskenazi, a professor of epidemiology and of maternal and child health at the University of California, Berkeley. For this study, researchers measured levels of organophosphate pesticides in urine samples collected on five occasions from 279 children in California's Salinas Valley between the ages of 6 months and 5 years. The area is an agricultural hub, producing lettuce, grapes, ... Read more

'Green' Public Housing May Help Families Breathe Easier

Posted 20 Oct 2015 by Drugs.com

TUESDAY, Oct. 20, 2015 – Low-income families living in "green" public housing may have fewer problems with asthma and other respiratory conditions, a new study finds. Researchers found that children living in Boston's newer, greener public housing had fewer asthma attacks, hospital visits and missed school days, compared with their peers in standard public housing. Adults, meanwhile, were less likely to report symptoms consistent with a condition called "sick building syndrome" – which include dizziness, headaches, nausea and eye irritation. The research, reported in the American Journal of Public Health, did not find a cause-and-effect link that proves green housing improves people's respiratory health. But it makes sense that it would, said lead researcher Meryl Colton, who was at the Harvard T.H. Chan School of Public Health in Boston when the study was conducted. It's known that ... Read more

Heating, Cooking Are Top Contributors to Air-Pollution Deaths Worldwide

Posted 16 Sep 2015 by Drugs.com

WEDNESDAY, Sept. 16, 2015 – While traffic exhaust and power plant emissions are the leading causes of air pollution deaths in the United States, that's not the case worldwide, a new study reports. Instead, smoke spewing from wood-burning stoves, and ammonia wafting from fertilizer and manure are the world's two biggest sources of deadly air pollution, according to results from a computer model of pollution's effect on human health. "Residential energy use is an inefficient form of fuel combustion that causes a lot of smoke, and is the foremost source of premature air pollution-related mortality in Asia," the region most affected by outdoor air pollution, said lead author Jos Lelieveld, a professor of atmospheric physics at the Max Planck Institute for Chemistry in Mainz, Germany. Deaths because of outdoor air pollution will double globally by the year 2050 unless nations improve their ... Read more
