Multiple Chemical Sensitivity Disorder

We know that some chemicals cause disease. Many people are sensitive to chemicals (synthetic and natural) that are found in carpets, plastics, perfumes, plants, paint, and cigarette smoke. People who are sensitive to a wide range of chemicals have Multiple Chemical Sensitivities (MCS) or Environmental Intolerance (IEI). Individuals with MCS/IEI can react to small amounts of chemicals found in everyday things, such as soaps, cosmetics, candles, and cleaning products.

While each individual with MCS/IEI reacts uniquely, the most common symptoms of multiple chemical sensitivity include:

  • Headaches
  • Rashes
  • Asthma
  • Muscle and joint aches
  • Fatigue
  • Memory loss
  • Confusion

The church, as a caring community, can work to create the most hospitable environment possible for people with MCS/IEI. Below are tips for caring responses for those living with MCS/IEI. As with any accommodation, it is a good idea to ask the person with MCS/IEI what specific changes would be most helpful for them.

Tips for Caring for those with MCS/IEI

For Congregations

  • Use unscented cleaning, laundry, and sanitizing products.
  • Clean the church early in the week to allow time for spaces to air out before Sunday.
  • Do not use air “freshener” sprays and plug-ins, incense, and scented candles.
  • Ventilate buildings with clean, fresh air, and use portable room air filters.
  • Advise the congregation in advance about planned maintenance projects, specifying the timing of paints, finishes, new carpets, and other chemical applications.
  • Avoid pesticides. Use the least toxic pest management possible and advise the congregation in advance of the scheduled service.
  • Create a scent-free zone with a door directly to the outside and a window to the sanctuary (or a livestream of the worship service). If a separate room is not possible, make a corner of the sanctuary scent-free.

For Individuals

  • Avoid using perfume, cologne, breath mints, cough drops, gum, and scented personal care products.
  • Do not apply lip balm or hand lotion in a public place, including the sanctuary or classroom. Apply these products before entering the building.
  • Do not use scented wet wipes or hand sanitizer in a public place. Wash hands and face in the restroom instead.
  • Avoid using aerosol spray products.
  • Avoid using products with strong odors to illustrate a sermon or Sunday School lesson.
  • Avoid snuffing out candles during a service.
  • Maintain contact with people who cannot attend church because of a chemical sensitivity. Before visiting them, shower with unscented soap and shampoo, and do not use scented products. If the weather permits, meet them outdoors instead of entering their home.

Beginner’s Guide to Church Attendance with MCS/IEI

  • Arrive at church early or late to avoid a crowded parking lot.
  • Wear a face mask or respirator and wash your hands before taking off it off.
  • Change clothes and shower right after church. Scents and chemicals can be transferred to your clothes, hair, and skin.
  • Avoid newly built or remodeled buildings.
  • Find an advocate in your congregation to help raise awareness of MCS/IEI and facilitate change.
