New York, Nov 16 (UNI) Stress can set off asthma by undermining the immune system, scientists say.
US researchers found soldiers who suffered from post-traumatic stress disorder were 2.3 times as likely to develop asthma than others.
The study, published in the American Journal of Respiratory and Critical Care Medicine, analysed 3,065 male twin pairs who were used to discount genetic factors.
Dr Renee Goodwin, the lead author, said,''It is conceivable that traumatic stress leads to increased vulnerability to immune system-related diseases, including asthma.'' UNI
