Multiple Chemical Sensitivity Awareness Month (M.C.S) is observed every year throughout May. M.C.S. is a chronic, physical illness that causes people to experience severe reactions when their bodies are exposed to very low levels of toxins or chemicals in food, chemical products, or their immediate environment. Though M.C.S. hasn’t been recognized as an illness, it’s still important to offer support to those forced to live with it, as well as raise more awareness about the illness itself.

History of MCS Awareness Month

Multiple chemical sensitivity, also known as environmental sensitivities, is a physical illness that causes people to experience allergic-type reactions when exposed to very low levels of chemicals in cleaning products, food, medicines, natural products, electromagnetic fields, etc. This occurs when the immune and detoxification systems stop working properly, preventing the body from effectively processing toxins. M.C.S. affects people of all ages and can be triggered by a large variety of factors. Common triggers of allergic reactions include tobacco smoke, exhaust fumes, pesticide, perfume, detergent, shampoo, and chlorine. Often, symptoms manifest in the form of headaches, dizziness, fatigue, breathing problems, sneezing, nausea, nasal congestion, itching, sore throat, chest pain, changes in heart rhythm, skin rash, bloating, confusion, trouble concentrating, memory problems, mood changes, and muscle pain.It is believed that the common causes of M.C.S. are prolonged or repeated chemical exposure or one-time exposure to certain toxins. It can also develop after a period of ill health or a viral infection. Unfortunately, there is no prescribed treatment method or cure for M.C.S. Some people find that avoiding certain products or foods alleviates symptoms.However, neither the World Health Organization nor the American Medical Association has recognized M.C.S. as an illness. Some groups, such as the Health Justice Commons, advocate against the stigmatization of people with M.C.S. They call on the rest of the world to recognize the role of people with M.C.S. as ‘planetary whistle blowers’ whose bodies alert us of the presence of toxins that may be otherwise indiscernible.
