Modern homes contain thousands of synthetic chemicals that were never part of human environments throughout our evolutionary history, creating indoor air pollution levels that often exceed those found in heavily industrialized outdoor areas. These chemical exposures occur through common household products, building materials, and consumer goods that appear safe but release volatile organic compounds, endocrine disruptors, and other toxic substances into the air you breathe and surfaces you touch every day.

Indoor air pollution from household products including cleaning supplies, air fresheners, personal care products, and furniture can create chemical exposures that are two to five times higher than typical outdoor levels. Volatile organic compounds emitted by these products can cause immediate symptoms including headaches, dizziness, and respiratory irritation while contributing to long-term health problems including asthma, allergies, and potentially cancer through chronic exposure.

Cleaning products contain numerous toxic chemicals including ammonia, chlorine bleach, quaternary ammonium compounds, and synthetic fragrances that can cause respiratory problems, skin irritation, and systemic health effects. The combination of different cleaning products can create dangerous chemical reactions, while the regular use of antimicrobial cleaners may contribute to the development of antibiotic-resistant bacteria and disruption of beneficial microorganisms in the home environment.
