Dust mites live in carpeting and bedding. Vacuums can actually stir up dust and molds. Synthetic fibers in upholstery to electric devices to shower curtains can also harbor formaldehyde gases which can worsen allergies and asthma. Heating systems can blow molds, bacteria and pet dander back into the air. Your home or office could be major sources of allergens and toxic fumes.
Many household cleaners give off toxic fumes.
Air conditioning can harbor molds that can grow very fast when not in use and then turned on. Poor ventilation, dirty filters are also major culprits. Doctors and leading experts in the field of environmental health recommend that it is important to take an evaluation of your own personal environment. It makes good sense to reduce or eliminate the causes for so many illnesses such as asthma and allergies in children, for instance. Toxins build up in the body on the cellular level, causing immune deficiencies and sensitivities.
