  • Building materials such as brick and cement
  • Household plants
  • Computers and other technologies
  • Consumer household products, especially chemical cleaning products

    VOCs released by consumer and industrial products are two to three times higher than previously estimated, and contributions to air pollution from household products are now estimated to be 50 percent of VOC air pollution. Learn more.

4 Which of the following is a leading cause of heart attacks in otherwise healthy women under 55?

  • Extreme physical exercise
  • Extreme emotional stress and/or "heartbreak"
  • Spontaneous coronary artery dissection (SCAD)

    Symptoms of an uncommon type of heart attack known as SCAD are easily overlooked, as few SCAD patients have risk factors for heart disease. Yet it's a leading cause of heart attacks in healthy women under 55; 80 percent of SCAD patients are women and 20 percent have recently given birth. Learn more.

  • Smoking

5 Rhabdomyolysis is a condition triggered by:

  • Hormone imbalances

6 While dozens of variables can have a significant influence on Alzheimer's, this degenerative neurological disease is primarily rooted in:

  • Insufficient exercise
  • Nutritional deficiencies
  • Lack of mental engagement

7 Which of the following organizations provide the highest level of organic standards and certification?

  • U.S. Department of Agriculture
  • Organic Certifiers
  • Quality Assurance International
  • Biodynamic/Demeter
