What do we know 1 Running head: WHAT DO WE KNOW ABOUT MULTIPLE CHEMICAL SENSITIVITY? WHAT DO WE KNOW ABOUT MULTIPLE CHEMICAL SENSITIVITY?

What do we know 2 Multiple Chemical Sensitivities (MCS) affects between 12.6 % and 33 % of the population and involves sensitivity to and illness reactions from exposures to chemicals in ambient air. Symptoms can affect any organ system and commonly include headaches, dizziness, fatigue, digestive problems, skin reactions, and many others. The condition is often initiated by one large chemical exposure, a series of low-level exposures, or presence during remodeling (with exposure to fresh paint, carpet, and other chemicals). More women than men may be affected. Life impacts include the loss of work, a decline in finances, difficulty finding safe housing, a lack of medical care, psychological upset, and the need to negotiate disability status. Qualitative researchers have discussed themes of isolation, loss of feelings of productivity, identity changes, and the need to cope with disbelief and delegitimization from others. It is imperative to acquire a greater understanding of this problem in order to both help those who have already sensitized and to prevent greater numbers of persons from becoming affected
