Boston Children's Hospital saw a precipitous drop in cases during the spring shutdown, and the trend continues. Researchers are asking why — and what it would take to keep up the change post-pandemic.
Young athletes — especially girls — can struggle with a breathing problem that appears to be asthma. The real cause of the problem is in the vocal cords.
Among Native Americans, asthma rates are high, and those with asthma end up in clinics more often, miss more school and work, and are more likely to die from the condition, according to the CDC.
Pregnant women and people with chronic health conditions such as asthma, diabetes and heart disease are particularly vulnerable to flu complications yet lag the elderly in getting vaccinated.
Many of the 26 million Americans with asthma use a low-dose steroid inhaler daily to prevent symptoms. But a recent study raises questions about this strategy for people with mild, persistent asthma.
New cases of asthma dropped dramatically in Los Angeles communities where air quality improved the most over 20 years. The results illustrate health benefits from pollution control.
A research team tracked the diets and exposures to air pollution of kids inside Baltimore homes. Children with diets high in omega-3 fatty acids seemed less vulnerable to pollution's effect on asthma.
Low-income residents living near highways and agricultural and industrial zones are getting hit with a "double whammy" as wildfire smoke drifts to areas where the air is often polluted already.
Some health systems are encouraging selected emergency room patients who are sick but stable and don't need intensive, round-the-clock care to opt for hospital-level care at home, instead.
Public health agencies are set up to regulate air pollution from cars, trucks and factories. Wildfire smoke presents a different set of threats, prompting some of those agencies to rethink priorities.
Last summer's wildfires handed scientists a rare chance to study effects of smoke on residents. Most previous work had been on wood-burning stoves, urban air pollution and the effects on firefighters.
Women are more likely to have asthma than men. One possible reason? Testosterone could block a protein that helps spark an asthma attack, a study finds, while estrogen may not.
As wildfires spread through Northern California counties, clouds of smoke and ash are spreading, too, far beyond the flames. Air quality officials have a database that's searchable by ZIP code.
But that's not the final word, caution pediatricians, including the Danish author. It's one of several recent studies with contradictory findings that suggest the supplements could help or hurt.
Older siblings can be annoying know-it-alls, but research suggests they may also help younger siblings build up stronger immune systems. And that may help reduce the risk of asthma and allergies.
Most genetic studies look only at people of European descent. But black and Hispanic children are far more likely to die of asthma, and genetic differences may help explain why.
Dust mites, gall wasps and book lice don't bite, but they might make you wheeze. Scientists found about 100 types of arthropods wiggling or munching skin flakes in typical homes. Take a look.
Dust mite allergies are a common trigger for asthma. A new form of immunotherapy that relies on oral tablets rather than shots reduces the risk of a moderate or severe asthma attack, a study finds.
Some people struggle for years with asthma and sinus infections, unaware that they have a disease called aspirin-exacerbated respiratory disease. For them, aspirin can be both cause and cure.
A small study suggests that slathering newborns with their mothers' microbes after cesarean sections could help create healthy microbiomes. Reducing childhood illness later on is the goal.
For the first time in decades, the number of children with asthma isn't increasing, federal scientists report. But cases continue to rise among African-American children and poor children.
Researchers find that babies lacking four types of bacteria in their guts at 3 months appear to have a higher risk for developing asthma later in life.
Cities and towns across the West are warning residents that high levels of smoke from forest fires threaten their health, with no sign of abating. That means indoor recess and no vacuuming.
Health care should go beyond a doctor's office, the creators of this program say. Students work as health advocates, helping patients find affordable housing, fresh food and social services as needed.
