I am a Registered Nurse now retired because of chemical injury. One thing seldom addressed is the indoor air quality in hospitals. The chemical loads in hospitals increases daily and the body load can only tolerate so much before chronic illness manifests.
Nursing is a busy, stressful career.
Add perfumes, outgassing from computers, printers, toxic cleaning products and many others and for many the health can suffer. We have the example of a group of nurses at Brigham and Women's in Boston. For many of us it is the end of our careers. Our numbers are growing. I now communicate with nurses and doctors in other countries.
