Why some people have asthma

The observed fact that poor people and minorities have more asthma than richer people could be due to the social environment as well as the physical one. Researchers have found that a stressful environment during pregnancy causes increased production of cord blood cytokine, and this seems to be related to increased risk of asthma.

The stress in the study was measured by a detailed questionnaire about stressors in their homes, finances, and neighborhoods, including domestic and community violence.

Another factor is lack of vitamin D.

On the other hand, family mealtimes seem to ease asthma, maybe because it lowers separation anxiety.

Too much or too little of so many things causes such bad stuff.
