Stress Relief Strategies to Ease Allergy Symptoms

If you suffer with allergy symptoms, you know all about the stress of having a chronic condition. Not only is it difficult to breathe with allergy symptoms, but poor sleep can lead to fatigue and problems concentrating. Allergy medicines can cause appetite changes, low energy, and even irritability. All you want is relief: from the stress, the symptoms, all of it.

Facts About Dust Mites

Dust mites are everywhere -- anywhere there are people or animals, warm temperatures, and high humidity. They like to be indoors, where they can get plenty of food like mold spores and dead skin cells from people and pets.

If you are sensitive or allergic to them, you may have:

  1. Watery, red eyes
  2. Runny or itchy nose and sneezing
  3. Sore throat or hoarse voice
  4. Coughing and other breathing problems
  5. Skin rash and itching

Each year, dust mites cause about 200,000 people with asthma to go to the emergency room.

Dust mites settle down in carpet, draperies, stuffed animals, and upholstered furniture. Mattresses, pillows, and soft bedding are favorite hangouts.

Dust Mite-Proof Covers

Dust mite covers really work. One study found that kids with asthma who were allergic to dust mites were able to cut their medicine in half when they used mattress and pillow covers. Tests of their mattresses showed that dust mites colonies there dwindled.

You can find dust mite covers for mattresses, pillows, and box springs at mattress and allergy supply stores and in a variety of materials.

  • Plastic or vinyl covers with zippers help seal in allergens so you don't inhale them when sleeping.
  • Plastic or vinyl covers are easier to keep clean than covers made of natural fibers.
  • Many plastic covers have an outer layer of material like nylon to make them more comfortable.
  • If possible, cover your mattress and pillows when they are new.
  • Put duct tape or electrical tape over cover zippers to double-block dust-mites from coming and going.

More Ways to Minimize Dust Mites

  • Use a bed with a wooden or metal frame.
  • Wash bedding in hot water. Cold water does not kill dust mites.
  • Wash sheets and pillowcases at least once a week. Wash comforters and bedspreads every one to two months.
  • Replace wool blankets with synthetic ones.
  • Consider using an electric blanket, which can reduce humidity on bed surfaces.
  • Wash and dry stuffed animals often and keep them off beds.
  • Clean mattresses in late winter and early spring. That will kill any dust mites that survived the winter and reduce their numbers in the summer months.
