Lupus is an autoimmune disease. This means that the body's natural defense system (immune system) attacks healthy tissues instead of attacking only things like bacteria and viruses. This causes inflammation. Although some people with lupus have only mild symptoms, the disease is lifelong and can become severe.
Heat Settings for Fabrics.
