Stressful and depressing events could make certain children's asthma worse. Researchers from the State University of New York at Buffalo showed 90 children with asthma scenes from E.T. The children were 7-17 years old and half of them had depression as well as asthma. The children with asthma and depression consistently showed breathing difficulties after watching distressing scenes from the film whereas the children with asthma but no depression were unaffected.
