Allergy busting

We've always known that some common household substances can cause reactions - what's different now is that they're on the increase - because our modern houses are so well sealed.

According to one recent survey, 38% of adults in America experience symptoms of allergies. The American College of Allergy, Asthma, and Immunology said that was nearly double what it expected to find.

And even if you don't suffer an extreme allergic reaction, irritations are said to be more common.

Many doctors believe it's because insulating homes seals in the chemicals and parasites, like house dust mites, which cause the problems.

And of course we live in a world of artificial chemicals, from cleaning solutions to paints and dyes.
