Airway hyperresponsiveness in asthma induced by methacholine is partly due to mast cells, a new study reports.
The chances of having asthma are three times higher in teenagers who go to bed late at night compared to those who sleep earlier. The risk of allergic rhinitis is two times higher for late sleepers. Researchers say they can not be certain that staying up late is a cause for asthma, however, they note melatonin is often out of sync in late sleepers, and that could be an influential factor in the allergic response.
On average, women have to work harder to breathe during strenuous exercise than men. The findings not only shed light on how sex may affect exercise dynamics but also the differences in how men and women experience airway disorders, such as asthma and COPD.

Additionally, children may face an increased risk of depression, obesity, and autoimmune diseases as they age.

A new study reveals marijuana may be present in breast milk six days after exposure. Researchers report 63% of samples taken from mothers who used cannabis contained traces of THC up to six days after using the drug.
Kids who play in dirt face exposure to germs and parasites that can help reduce risks of suffering certain allergies and illnesses later in life. Early microbial exposures help our bodies to learn how to regulate inflammation, researchers say.
Researchers have identified a receptor protein that regulates immune response intensity in response to allergens.
According to a new study, children of mothers who took a specific asthma medication while pregnant faced an elevated risk of being diagnosed with autism spectrum disorder.
