What is Multiple Chemical Sensitivity

Multiple Chemical Sensitivity description. Find out what Multiple Chemical Sensitivity is and know more about it.


Multiple Chemical Sensitivity (MCS) is a condition in which individuals experience adverse reactions to various chemical substances found in everyday environments. These substances can include perfumes, cleaning products, pesticides, and even certain foods. People with MCS may develop symptoms such as headaches, dizziness, fatigue, difficulty breathing, and skin irritations when exposed to these triggers.


The exact cause of MCS is not fully understood, but it is believed to result from a combination of genetic, environmental, and immune system factors. Some individuals may be more susceptible to developing MCS due to pre-existing allergies or sensitivities.


Managing MCS involves avoiding exposure to the specific chemicals that trigger symptoms. This may require making lifestyle changes such as using fragrance-free products, improving indoor air quality, and adopting a healthy diet. Additionally, individuals with MCS may benefit from seeking support from healthcare professionals who specialize in environmental medicine.


It is important to note that MCS is a complex and controversial condition, and its recognition as a medical diagnosis varies among healthcare providers. Further research is needed to better understand the underlying mechanisms and develop effective treatments for those affected.

When someone has an adverse reaction to a chemical in their environment.

1/6/19 by Cindi 3050

When I answer the door to a delivery man who enters my house for a few minutes to put a heavy parcel down and he is covered in Lynx aftershave I feel exactly like I am being punched in the face repeatedly. When he leaves I am in such a state I cannot think properly, I am highly distressed and I dry vomit and cough and void my bowels. I have nasty headaches as if someone is poking long steel needles into my eyes and head. I have to lie in a darkened room for 72 hours. If someone kind takes me shopping I have to dart away from the smell of people. I get home and put my shopping away. I'm then ill for 72 hours and all the fresh vegetables go off. What a waste. I don't go out much. I'm trapped in my home. There's no pill. The cure is for everyone to feel as I do and then we will stop using poison.

It is when your body cannot handle breathing in strong scents, specifically detergents like Tide, Gain, All, dryer sheets like Bounce, fabric softeners like Snuggle, strong perfumes and colognes, deodorants like Secret, Arid, strong cleaning products, air fresheners like Febreze, Glade, and many other things as such. We get dizzy, we have trouble speaking, we might faint, feel sick, nauseated, tired or emotional. We can't breathe properly. We become isolated and fearful. It isn't normal, goes against the grain of human nature.

Immunological response to your environment causing debilitating, life threatening reactions

Some people cannot process even small amounts of toxic [to them] triggers of chemical structures that others have no noticeable reactions to. When these people must remove themselves from these triggers and go to a queit space with clean air, and water to recover, we say they have MCS or chemical intolerance, or environmental intolerance. Really it is these people that are well, and their environment is toxic. Therefore many refer to them as canaries, as those in coal mines, that signal danger.

A normal reaction to the abnormal world conditions

MCS is a chronic illness that causes a person to not be able to tolerate chemicals that are typically tolerable. When a chemical is intolerable, that means that it produces any number of sick-like symptoms, including those which I listed in a previous stub. It is also an environmental illness -- caused by what is in our environment. It is a syndrome, because it affects multiple organ systems.

MCS is a genetic disease that negatively impacts the body's ability to detox natural and synthetic chemicals, leading to the development of a toxic load and reactivity.
