Risk Of Asthma Rises Due to Endotoxins
Asthma can be triggered by exposure to endotoxins
in the house, according to the American Journal of Respiratory and Critical Care Medicine study. Humidifiers, pests, dust, pets, and outdoor // air are common sources of endotoxins, according to the University of Iowa’s Dr. Peter S. Thorne.
