People with asthma who vape tend to develop the respiratory disease earlier in life than folks who never vaped, new research shows.

Overall, asthmatic adults who said they'd vaped over the past month were over three times as likely to have developed asthma relatively early in life (before the age of 27) com...

People in homes with gas or propane stoves regularly breathe in unhealthy levels of nitrogen dioxide, a new study says.

Typical use of these stoves increases exposure to nitrogen dioxide (NO2) by an estimated 4 parts per billion, averaged over a year, researchers report.

A protein that shuts down immune cells in the lungs could be key to a new treatment for asthma attacks, a new report says.

The naturally occurring protein, called Piezo1, prevents a type of immune cell called type 2 innate lymphoid cells (ILC2s) from becoming hyperactivated by allergens.

An expe...

Planting trees and bushes near busy highways helps clear the air of harmful air pollutants from motor vehicles, new research affirms.

"They provide benefits that go beyond aesthetics," Roby Greenwald, an associate professor of public health at Georgia State University in Atlanta, said in a university news release.


There's a toxic stew of chemicals in polluted air that can all trigger asthma attacks in kids, new research shows.

Also, where a child lives -- for example, near factories or highways -- greatly influences how much they're exposed to these toxins, reports a team from Washington State University in Spokane.

    People threatened by accidental exposure to foods they're allergic to may have a new weapon of defense: On Friday, the U.S. Food and Drug Administration expanded the use of the asthma drug Xolair to help prevent anaphylactic reactions.

    Xolair (omalizumab) is an injected drug and is not meant as a substitute for EpiPens or other anaphylaxis rescue remedies, the agency stressed.


    The U.S. Environmental Protection Agency has announced that it is cracking down on air pollution.

    Specifically, the agency introduced a tougher air quality standard that takes aim at fine particulate matter -- the tiny bits of pollution that can penetrate the lungs -- by lowering the allowable annual concentration of the deadly pollutant that each state can have.

    "This final air qua...

    Deaths related to ozone air pollution will rise significantly around the world during the next two decades due to climate change, a new study warns.

    In response, the lung association's "State of Tobacco Control"r...

    Fetal exposure to opioids may change a baby's immune system, triggering a rise in risks for eczema and asthma through early childhood, new research shows.

    Children born to women who used opioids during pregnancy had much higher rates of eczema, as well as conditions such as "diaper rash," during infancy, Australian researchers report.

    These children also went on to have significantl...

    An American's income and ethnicity could play a role in how clean the air is that they breathe, a new study finds.

    Air pollution emissions have fallen more in wealthier areas, and less in areas with larger Hispanic or American Indian populations.

    Overall, U.S. air pollution emissions have decreased substantially, but the magnitude of the change varies based on demographics, the rese...

    Drugs already used by millions to lower cholesterol might someday have a new role: Relieving asthma and COPD.

    Research into a possible link between childhood health problems and natural gas wells in western Pennsylvania is wrapping up with some answers.

    It may not get the publicity of some better-known vitamins like D, but vitamin K -- found in leafy green vegetables -- may boost lung health.

    A new, large study -- published Aug. 10 in ERJ Open Research -- suggests that people who have low levels of this vitamin also have less healthy lungs. They are more likely to report having asthma, chronic obstructive pulmonary disease (COPD...
