New building products contain neurotoxic chemicals. A new house takes 12 years to off gas formaldehyde embedded in insulation, plywood, plastics, and other products. Did you know you can buy John Mansfield insulation which has no checmials in it? Did you know that there is a company called AFM that sells products to seal in chemicals? They have a myriad of products that I've used for all my household needs. Some of their products have saved me from reactions so I could live in my home comfortably, without brain fog, headaches, dizziness, nausea, or fatigue.
Check out a product's chemical content before you have it installed in your house. Chose real wood instead of vinyl look-like-wood. Chose tile instead of carpet then buy hemp, suisal, or other natural products and spread healthy throw rugs around.
Buy mindfully so your brain and body will be happy.
