sensitivity to scents - from www.thecanaryreport.org/.../comment-page-1/ Exposure to modern fragrance adversely impacts health June 19, 2009 by Susie Collins Several studies indicate that 15-30% of the general population report some sensitivity to chemicals, including fragrances, and 4-6% report that chemical intolerance has a major impact on their quality of life. Healthy House Institute reports on scents and sensitivity with a well-researched, detailed article covering the problems with synthetic fragrance and the impact on health. The full article is well worth your time to read, and I think would be an excellent resource for you to show family, friends or co-workers who do not fully understand Multiple Chemical Sensitivity. While many people enjoy wearing perfumes and using scented products, there is a growing outcry from some people who claim that exposure to certain fragrances, including perfumes and scented products, adversely impacts their health. They report symptoms such as headaches, dizziness, nausea, fatigue, shortness of breath, difficulty with concentration, and allergy-like symptoms. It has been shown that many asthmatic patients have adverse reactions to perfumes and other fragrances, and some researchers hypothesize that exposure to fragrance may actually cause asthma. People who suffer from multiple chemical sensitivity (MCS), a health condition in which exposure to one chemical is thought to lead to adverse reactions to other chemicals, claim that exposure to fragrance triggers various symptoms, often to the point that sufferers are incapacitated or must forgo many of their usual activities to avoid exposure. As information continues to surface on the issue of indoor air pollution, it appears that fragrances may represent part of the problem. Some researchers believe that exposure to the types of chemicals found in many scented products may contribute to the development and exacerbation of sick building syndrome, a health condition allegedly caused by indoor air pollution. The chemicals in perfumes, colognes, and deodorants worn by employees add to the chemical mixtures in indoor air, as do fragrances in cleaning products. In addition, some building owners pump certain fragrances–believed to evoke an emotional response that results in increased work productivity–through office ventilation systems. Claudia Miller, an associate professor of environmental and occupation al medicine at the University of Texas Health Sciences Center in San Antonio, says that several studies indicate that 15-30% of the general population report some sensitivity to chemicals, including fragrances, and 4-6% report that chemical intolerance has a major impact on their quality of life. Of these people, more than 80% report that exposure to fragrances is bothersome. Miller, who has conducted extensive research on MCS and coauthored the book Chemical Exposures: Low Levels and High Stakes, adds that many Gulf War veterans reported chemical intolerances since the war, including sensitivity to fragrances.
