We spend just about a third of our days sleeping, so it is important that the air in your bedroom be as pristine as possible. Some tips to minimize bedroom allergens:

• Vacuum often with a HEPA (high-efficiency particulate air) filter vacuum, which prevents dust particles from recirculating.

• Wash bedding weekly in hot water (130°F) and dry in a hot dryer.

• Replace bedding made of natural materials like down and cotton with bedding made of synthetic fibers.

• Encase mattresses and pillows in dust mite-proof covers.   Wash blankets and pillowcases which aren't encased once a week in hot water.

•  Do not allow pets into the bedroom. A study by Dr. Shepard of the Mayo Clinic Sleep Disorders Center (USA) reported that 53% of pet owners permitting the animal in the sleeping room had disrupted sleep every night. Pet allergies can also contribute to problems breathing during sleep.

•  Leave dust-prone plants, knick-knacks, and fuzzy stuffed toys out of the bedroom.

The indoor environment [as compared to the outdoors] has higher contaminant levels and provides more immediate and prolonged exposure to pollutants.  ~ Battelle Memorial Institute (USA)
