Many consumers are surprised to learn that some of the everyday household products they use contain hundreds of chemicals. In addition, some of these products do not have to be tested for safety prior to going on the market. Dr. Oz talks with Jane Houlihan of Environmental Working Group, a nonprofit research and advocacy organization dedicated to protecting human health and the environment, about simple things you can do to make sure you're not being exposed to chemicals that may present risks to your health.

• Avoid fragrances. Fragrances are one of the top allergens and can contain chemicals that are toxic to the brain and pose risks to reproduction, Jane says. And yet, the components of fragrances don't have to be listed on product labels, she says.
• Avoid powders. These can be easily inhaled and therefore may present a greater health risk, Jane says.
• Avoid synthetic preservatives and colors. "All of those can have toxic properties," Jane says.
• Limit the number of products you use. Women on average use about 12 products a day and 170 unique chemicals, Jane says. Take a look at what can you cut out of your daily routine, which will then cut down on your exposure, she says.
