How chemically sensitive are you?

Answer these three questions from the Brief Environmental Exposure and Sensitivity Inventory (BREESI):

Do you feel sick when you are exposed to tobacco smoke, certain fragrances, nail polish/remover, engine exhaust, gasoline, air fresheners, pesticides, paint/thinner, fresh tar/asphalt, cleaning supplies, new carpet or furnishings? By sick, we mean: headache, difficulty thinking, difficulty breathing, weakness, dizziness, upset stomach, etc.

Are you unable to tolerate or do you have adverse reactions to any foods such as dairy products, wheat, corn, eggs, caffeine, alcoholic beverages, or food additives (e.g., MSG, food dye)?

If you answer YES to any of these three questions, take the Quick Environmental Exposure and Sensitivity Inventory (QEESI) and share the results with your doctor!
