Workers, take heed: Your place of work can help bring on or exacerbate asthma, a new study suggests.
Common workplace triggers include poor ventilation and moldy air conditioning systems, cleaning products and even the toner used in printers, the researchers said. Employees with asthma caused by the office environment often quit, the researchers said, especially if employers don't do anyt...
It's more than just an annoyance: Long-term exposure to traffic and train noise may increase the risk of dementia and Alzheimer's disease, Danish researchers report.
The study authors said that more than 1,200 of Denmark's nearly 8,500 cases of dementia in 2017 may have resulted from exposure to noise, which means that reducing traffic noise might help prevent the thinking, memory and beh...
Hotter weather driven by climate change is bad news for people with chronic obstructive pulmonary disease (COPD), a new study warns.
Researchers say warming trends could worsen COPD symptoms, such as shortness of breath, wheezing or coughing. Millions of people have COPD, a combination of emphysema and chronic bronchitis that is often tied to smoking.
While breathing in secondhand smoke is known to harm kids' lungs, new research suggests that children whose parents smoked are also more prone to developing rheumatoid arthritis later in life.
"Our findings give more depth and gravity to the negative health consequences of smoking in relation to [rheumatoid arthritis], one of the most common autoimmune diseases," said lead author Dr. Kazu...
Air pollution could cause sinus misery, new research suggests.
Specifically, tiny particulate air pollution (known as PM2.5) could contribute to chronic rhinosinusitis, a condition in which the sinuses get infected or irritated, become swollen, are severely congested and secrete mucus into the throat for 12 weeks or more.
"To our knowledge, this is the first study to report that lon...
Sun protection is essential as you enjoy the outdoors this summer, a skin expert stresses.
"Skin cancer is the most common cancer in humans so it's important that we do what we can to protect ourselves," Dr. Ida Orengo, a professor of dermatology at Baylor College of Medicine in Houston, said in a school news release.
If you thought the air was cleaner at the height of the COVID-19 pandemic, you weren't imagining it. But clean skies were less evident in poorer areas of the United States, a new study finds.
COVID-19 pandemic-related lockdowns reduced overall levels of nitrogen dioxide air pollution in many U.S. cities. However, levels remained higher in poorer, minority neighborhoods than in richer, whi...
Breathing in smoke from wildfires may significantly increase the spread of COVID-19, researchers say.
The warning, from a new study of links between smoke-caused air pollution and SARS-CoV-2 infections, comes as firefighters battle 80 large wildfires in the western United States. The largest -- 300 miles south of Portland, Ore. -- covers over 500 square miles.
Extreme heat strikes poor and minority neighborhoods in U.S. cities harder than those that are wealthier and mainly white, a new study finds.
"The distribution of excess urban heat varies within cities, and as a result, communities do not share a city's extreme heat burden equally," said study co-author Jennifer Burney. She's chair of global climate policy and research at the University o...
Can childhood lead exposure affect personality into adulthood?
Yes, a big multi-decade study suggests.
The finding stems from an analysis of data on atmospheric lead levels across the United States and 37 European nations since 1960. Lead levels were stacked up against responses to a personality survey of roughly 1.5 million men and women.
Climate change has already become deadly enough to cause 5 million extra deaths worldwide each year, researchers report.
"This is the first study to get a global overview of mortality due to non-optimal temperature conditions between 2000 and 2019, the hottest period since the pre-industrial era," said study co-leader Yuming Guo, a professor at Monash University in Australia.
Could trees be the key to a cool summer in the city?
Yes, claims new research that calculated just how much greenery can bring temperatures down.
"We've long known that the shade of trees and buildings can provide cooling," said study co-author Jean-Michel Guldmann. He is a professor emeritus of city and regional planning at Ohio State University, in Columbus.
As the pandemic eases and children flock to playgrounds this summer, parents need to make sure their kids are safe, the American Academy of Orthopaedic Surgeons (AAOS) says.
"After a challenging school year and months of being socially distanced and kept apart from their friends, children are eager to get outside and play," said AAOS spokesperson Dr. Rachel Goldstein. She is a pediatric o...
The good news: Levels of lead in the air that Londoners breathe are far lower today than they were in the 1980s, when leaded gas was an automotive staple.
The bad news: Decades-old lead particles still pollute the city's air, a stubborn and potentially hazardous leftover of a now banned product. The findings might have implications for the health of city dwellers globally.
A leading medical group is offering testing guidelines for children with autistic behaviors.
The American Academy of Pediatrics Council on Environmental Health emphasized that certain measurements to test for exposure to chemicals are not helpful to guide treatment. The council pointed out that just because a chemical is found in the body doesn't mean it will cause harm.
Exposure to mold both in and out of the home may worsen breathlessness and other symptoms of chronic obstructive pulmonary disease (COPD), new research suggests.
More than 16 million Americans have COPD, according to the American Lung Association. COPD is an umbrella term for chronic lung diseases such as bronchitis and emphysema, which literally take your breath away. COPD flares can be...
In normal times, a sunny day can lift your mood while a stormy one can darken it, but new British research shows that weather had little effect on people's spirits during the pandemic.
"We know that lockdown restrictions, and the resulting impact on social life and the economy, are linked to at least two major negative public health consequences -- a reduction in physical exercise, both i...
Children may have an increased risk of obesity if their mothers were exposed to high levels of air pollution during pregnancy, researchers say.
In a new study, 123 Hispanic mother-infant pairs were enrolled in an ongoing trial in the Los Angeles region. Before pregnancy, about one-third of the mothers were normal weight, one-third were overweight and one-third were obese.
Human-caused global warming is responsible for more than one-third of heat-related deaths worldwide, but the proportion is much higher in certain countries, a new study finds.
Researchers analyzed data gathered between 1991 and 2018 from 732 locations in 43 countries. They concluded that 37% of all heat-related deaths in recent summer periods were attributable to the warming of the planet...
A native South American population that lives a pre-industrial lifestyle may have a slower rate of brain aging than the typical Westerner, a new study finds.
The study focused on the Tsimane population, whose roughly 16,000 members dwell in a remote part of the Bolivian Amazon. They live by farming, hunting, gathering and fishing - a lifestyle devoid of processed food, couch time and stre...
Rising temperatures caused by climate change could trigger a worldwide increase in stillbirths, researchers warn.
The team at the University of Queensland in Australia analyzed 12 studies on the subject. They found that exposure to extremely high temperatures throughout pregnancy appeared to increase risk of stillbirth, particularly late in pregnancy.
Sixty-seven percent of inmates in California prisons who were offered a COVID-19 vaccine have accepted at least one dose, a Stanford University study found.
"This is one of the largest state prison systems in the country, and if it can achieve high vaccination coverage among its incarcerated population, then the federal and other state prisons systems can and should do the same for the mo...
Steaks and burgers could be killing thousands of Americans each year, but in a way most people wouldn't expect -- via air pollution.
That's the conclusion of a new study estimating that airborne particles generated by food production kill nearly 16,000 Americans each year. Pollution related to animal products -- most notably beef -- accounts for 80% of those deaths.
Call it a silver lining of the pandemic: Asthma attacks fell sharply among Black and Hispanic Americans in the months after the coronavirus first surfaced.
The study included nearly 1,200 participants who provided information about their asthma through monthly online, phone or mail questionnaires for 15 months between the first half of 2019 and first half of 2020.
Air pollution isn't hard on the hearts of adults only, suggests a new analysis that found it can raise blood pressure in kids as young as 5.
Children experienced increases in blood pressure if they had short-term exposure to air polluted with coarser particles or long-term exposure to finer airborne particles, and that also happened with long-term exposure to nitrogen dioxide, an air poll...
The risk of dying within five years of a heart attack is notably higher among poor Americans than their wealthier peers, but race also plays a role, a new study reveals.
While Black residents of poor neighborhoods appear to face a higher risk of death than their counterparts in wealthier ZIP codes, poor Black patients are also more likely to die after a heart attack than poor white patien...
Increasing numbers of wildfires are making poor air quality more common throughout the Western United States, according to a new study.
The findings suggest that many cities may soon have trouble meeting air quality standards, said lead author Kai Wilmot, a doctoral student in atmospheric sciences at the University of Utah in Salt Lake City.
The Middle East and North Africa are already among the hottest spots on the planet, but new research warns that if nothing is done to slow climate change there will be life-threatening heat waves with temperatures of 132 Fahrenheit or higher in those regions.
"Our results for a business-as-usual pathway indicate that, especially in the second half of this century, unprecedented super- an...
Kids exposed to air pollution may be at risk for mental illness in early adulthood, a new study suggests.
Researchers found that young adults in Britain who were exposed to higher levels of traffic-related air pollutants during their childhood and teen years were prone to develop symptoms of mental illness later. Nitrogen oxides were a particular problem, the study authors reported.
When wildfires choked the air and turned the skies orange throughout the American West in recent years, they caused a variety of health problems from coughs and runny noses to life-threatening heart attacks and strokes.
But eczema and other skin issues were a result of the wildfires, too, according to researchers from the University of California, San Francisco (UCSF), and the University ...
Eviction bans during the COVID-19 pandemic reduced infection rates not only in people who avoided displacement but also in their communities, according to a new study.
"When it comes to a transmissible disease like COVID-19, no neighborhood is entirely isolated," said study author Alison Hill, assistant professor of biomedical engineering at Johns Hopkins University, in Baltimore.
